  When a route search request is output from the route calculation unit 23 to the vehicle information providing device 3 in step S202, the vehicle information providing device 3 calculates the presented route in the processing procedure (steps S401 to S411) shown in FIG. This is determined and transmitted to the route calculator 23 of the terminal device 2 (details will be described later with reference to FIG. 6). Next, proceeding to step S203, the route calculation unit 23 receives the information including the presentation route information, the power consumption information, and the charging route information transmitted from the vehicle information providing device 3 (from step S411 in FIG. 6). ). In step S202, when the presented route cannot be determined, the route calculation unit 23 receives planned route information instead of the presented route information.

  Subsequently, the process proceeds to step S204, and the route calculation unit 23 determines whether or not the information on the presented route has been received in step S203. If the route calculation unit 23 determines that the information of the presentation route has been received (step S204 = Yes), the route calculation unit 23 proceeds to step S205. On the other hand, if the route calculation unit 23 determines that the information on the planned route is received instead of the information on the presented route (step S204 = No), the route calculation unit 23 proceeds to step S207.

  If it is determined that the presentation route information has been received, the process proceeds to step S205. In step S205, the route calculation unit 23 obtains the information acquired in step S203 described above (presentation route information, power consumption information, and charging via point). The control command to display the information on the presentation route and the information on the waypoint through charging is output to the display unit 24. In the following step S206, the route calculation unit 23 displays a control command for displaying power consumption information among the information (presentation route information, power consumption information, and charging via point information) acquired in step S203 described above. After outputting to the unit 24, the route providing process is terminated. Thereby, the display shown in FIG. 2A is performed on the display screen.

  On the other hand, if it is determined that the presented route information has not been received, the process proceeds to step S207. In step S207, the route calculation unit 23 obtains the information (plan route information, power consumption information) acquired in step S203 described above. Control information for displaying the information on the planned route and the information on the charging route is output to the display unit 24.

  In the subsequent step S208, the route calculation unit 23 displays a control command for displaying power consumption information among the information (plan route information, power consumption information, and charging via point information) acquired in step S203 described above. After outputting to the unit 24, the route providing process is terminated. Thereby, the display as shown in FIG. 2A is performed on the display screen.

<History accumulation processing>
FIG. 5 is a flowchart showing a subroutine of the history accumulation process (step S30) of FIG. 2B. The history storage process is executed by the travel history storage unit 26 of the vehicle information providing device 3. When the travel history storage unit 26 receives the first travel history information or the second travel history information from the route calculation unit 23, the history storage process is performed. Execute.

  In step S301 in FIG. 5, the travel history storage unit 26 stores the first travel history information or the second travel history information received from the travel history recording unit 19 of the in-vehicle device 1 as travel history information, and ends the history storage process. To do. At that time, the travel history accumulating unit 26 also stores travel history information (first travel history information, second travel history information, second day, season, weather, travel time zone, air conditioner power consumption, travel power consumption, and average speed information). (Including travel history information).

  As information on the presence or absence of traffic jams, for example, the presence or absence of traffic jams can be detected in the travel date and time and the travel route included in the first travel history information, and the detected traffic jam information can be used. The day information includes, for example, the day of the week to which the traveling date and time included in the first traveling history information belongs. Furthermore, as the season information, for example, there is a season to which the date and time of travel included in the first travel history information belongs. Further, as the weather information, for example, the weather at the date and time of latitude and latitude and longitude included in the first travel history information can be detected, and the detected information can be used.

  Furthermore, as the time zone information, for example, the time zone to which the date and time of travel included in the first travel history information belongs can be mentioned. Examples of the information on the power consumption of the air conditioner include information on the air conditioner on / off included in the first travel history information and information on the power consumption per unit time of the air conditioner. The travel power consumption information includes, for example, a reduction amount per unit time of the remaining battery level during travel included in the first travel history information. Furthermore, examples of the average speed information include an average value in a set time (for example, 10 minutes) of the vehicle speed included in the first travel history information.

  In the present embodiment, the travel history recording unit 19 uses the information on the guide route output from the navigation device 18 as the travel route. However, other configurations may be employed. For example, when there is a portion in which the vehicle A actually travels on a different route in the travel route of the first travel history information, the travel history storage unit 26 stores the travel history stored in the travel history storage unit 26. Based on the information (latitude and longitude), the travel route on which the vehicle A actually traveled is corrected. Thereby, the travel history accumulating unit 26 accumulates information on the travel route on which the vehicle A actually traveled.

  As the information of the actually traveled route, a general latitude / longitude sequence after dead reckoning, or a road link sequence, and further a latitude / longitude sequence after map matching or a road link sequence can be adopted. Dead reckoning is, for example, position information obtained by correcting GPS latitude and longitude detected by the position detection unit 5 according to speed information from the vehicle speed detection unit 9. Furthermore, a method for improving the correction accuracy by adding information of a gyro sensor (acceleration sensor) (not shown) is also known and may be used. The map matching means the GPS latitude / longitude detected by the position detection unit 5 or the latitude / longitude after the dead reckoning, the road link and node information held by the navigation device 18, and the guidance route information if navigation is being performed. In addition, it is known as a method for detecting a plausible road location after determining whether or not the vehicle is traveling on a road and on which road the vehicle has passed.

  In this embodiment, when accumulating the travel route information output from the in-vehicle device 1, the start point and the end point that are the end points of the travel route are extracted, and only the information on the end points is accumulated. Data may be generated. Even if the position of the two end points and the travel route between them are the same travel route, the battery power consumption is different when traveling from one end point to the other end point and traveling from the other end point to the other end point. This is because they may be different. For example, when the altitudes of the two end points are different, the uphill and the downhill are reversed, and the power consumption of the battery increases when there are more uphills. Even if the altitudes of the two end points are the same, the degree of traffic congestion may be different between the upstream lane and the downstream lane, and the greater the traffic congestion, the longer the travel time and the power consumption of the battery. For this reason, the start point and end point of the travel route may be distinguished and stored in the sub-database. The information in this sub-database (referred to as the endpoint sub-database) can be used when determining the order of searching for the same / similar route, and specifically can be used for the processing in step S703 in FIG. Details will be described later.

<Running history statistical processing>
FIG. 6 is a flowchart showing a subroutine of the travel history statistical process (step S40) of FIG. 2B. The travel history statistical processing is executed by the history statistical processing unit 27 of the vehicle information providing device 3, and when the history statistical processing unit 27 receives the presentation route search request (step S202 in FIG. 4) transmitted by the terminal device 2. The following history statistical processing is executed.

As shown in FIG. 6, firstly in step S401, historical statistics processor 27 obtains the start point P _O and destination point P _D from the received presentation route search request. Then, the history statistical processing unit 27, based on the map information by the map information storage section 25 has stored, retrieves the planned route to the destination P _D from the start point P _O acquired (acquired). The planned route may be a route that can be reached from the starting point P _O to the destination P _D, it is not particularly limited, for example, capable of traveling a departure point P _O and destination point P _D in the shortest time travel A route, a travel route that travels in the shortest distance, a travel route that uses a highway / toll road, a travel route that uses a general road, and the like are set as necessary.

  In the present embodiment, the history statistics processing unit 27 provided in the vehicle information providing device 3 searches for (acquires) the planned route. However, other configurations may be employed. For example, the navigation device 18 provided in the in-vehicle device 1 may be configured to search for a planned route. In this case, if the navigation device 18 transmits the search result of the planned route to the history statistical processing unit 27 and the history statistical processing unit 27 receives (acquires) the planned route transmitted from the navigation device 18. Good.

  Subsequently, the process proceeds to step S402, and the history statistics processing unit 27 acquires information on the remaining battery level in accordance with the received presentation route search request. As a method for acquiring information on the remaining battery level, a method may be used in which the terminal device 2 makes an inquiry to the remaining battery level detection unit 11 of the vehicle A via the data center B, or the user inputs an arbitrary remaining battery level. It is good also as a method. According to the former method, the calculation based on the latest remaining battery level can be performed when actually departing, so that a result according to the current state can be obtained. In addition, according to the latter method, since the user can designate the remaining battery level in advance, for example, it is possible to obtain a result assuming that the battery starts after it is 100% charged.

Next, the process proceeds to step S403. In step S403, the history statistics processing unit 27 executes a similar route search process. FIG. 8 is a flowchart showing an example of the subroutine of step S403 in FIG. In step S701, the history statistics processing unit 27 sets a departure area R _O and a destination area R _D based on the departure point P _O and the destination point P _D included in the received presentation route search request. If the presentation route search request that contains the via point P _W is also set via regional R _W.

FIG. 7 is a diagram for explaining a similar route search method according to this embodiment. As shown in FIG. 7 (A), in the present embodiment, the history statistical processing unit 27 sets the circular range with a radius r _O centered on the departure point P _O to the starting area R _O, and, setting the circular range with a radius r _D centered on the destination point P _D in the destination area R _D. Also set to via local R _W a circular range with a radius r _W centered on the waypoints P _W. Note that the method of setting the departure area, the destination area, and the route area from the departure point, the destination point, and the waypoint is not limited to a circular range having a constant radius, and may be a predetermined geometric shape such as a regular polygon.

At next step S702, the history statistical processing section 27, the departure point P _O contained in presenting the route search _request, on the basis of the destination point P _D and via-point P _W, scan exclusion range if the search range of similar route (i.e. ) Is set. The search results include unintended travel routes, such as when the number of travel route data stored in the travel history storage unit 26 is enormous, or there are many combinations of travel routes in areas where the road itself is complex. there be, but in the present embodiment, these are not intended presentation route, start point P _O to the user in other words, _set, the distance relationships and temporal relationship between the object point P _D and waypoints P _W dilute Or prohibiting the provision of a simple travel route as a presentation route. Therefore, to suppress or inhibit the provision of presentation route larger than a prescribed threshold value for the distance relationship or temporal relationship between at least the starting point P _O and destination point P _D. In order to suppress or prohibit the provision of the presented route, as described below, the method for limiting the search range of similar routes and the search range to the full range as before, limiting the search results obtained. Any method may be adopted.

At least specific means for inhibiting the provision of presentation route larger than a prescribed threshold value for the distance relationship or temporal relationship between the start point P _O and destination point P _D are various contemplated. 9A to 9C, FIGS. 10A to 10D, and FIGS. 11A to 11B are road diagrams for explaining specific examples thereof.

First example shown in FIG. 9A, with respect to the straight line distance L connecting the start point P _O and destination point P _D included in the presentation route search request, N times the predetermined magnification (e.g. L (N is a positive number) ) With regard to the travel route described above, provision as a presentation route is suppressed or prohibited. May be a distance L in consideration of this case there is a height difference between the starting point P _O and destination point P _D. Since each of the starting point P _O and destination point P _D including altitude information and information latitude and longitude can be calculated linear distance L, set the value NL multiplied by the predetermined factor N to the ratio threshold . Then, from among the travel route start point of the travel route is present in the starting region R _O in such step S703, excluding those running distance of the travel route is more magnification threshold NL. Thereby, it is possible to suppress providing an unintended travel route such as a detour travel route as a presentation route.

Although not shown in FIG. 9A, if it contains waypoints P _W in presenting the route search request, a distance L ₁ of a straight line connecting the waypoints P _W as a starting point P _O, waypoint and a destination point A value N (L ₁ + L ₂ ) obtained by multiplying a distance L ₁ + L _{2 obtained} by adding a distance L _{2 of a} straight line connecting the _two and a predetermined magnification N is set as a magnification threshold value, and in step S703 and the like, the starting point of the travel route starts. What is necessary is just to exclude from the travel routes existing in the region R _O that the travel distance of the travel route is equal to or greater than the magnification threshold N (L ₁ + L ₂ ). In addition, when a plurality of waypoints P _W are included, the magnification threshold value may be set similarly.

The second example shown in FIG. 9B, with respect to the distance L of the planned route obtained from the starting point P _O and destination point P _D included in the presentation route search request, N times the predetermined magnification (e.g. L (N is a positive Number)) For travel routes that are equal to or greater than the above, provision as presentation routes is suppressed or prohibited. The planned route is calculated by the history statistics processor 27 of the vehicle information providing device 3 as described above, with reference to the map information by the map information storage section 25 has stored, the destination point P _D from the start point P _O up to, for example, it extracts the departure point P _O and destination point P _D as a travel route planning routes that travels at a possible travel routes and the shortest distance in the shortest time. Since this planned route includes travel distance information, a value NL obtained by multiplying the planned route by a predetermined magnification N is set as a magnification threshold. Then, in such step S703, from among the travel route start point of the travel route is present in the starting region R _O, excluding those running distance of the travel route is more magnification threshold NL. Thereby, it is possible to suppress providing an unintended travel route such as a detour travel route as a presentation route.

Although not shown in FIG. 9B, even if one or more waypoints P _W are included in the presented route search request, the obtained planned route is also a travel route that passes through this way point P _W. Therefore, NL obtained by multiplying the travel distance L of the planned route by a predetermined magnification N may be set as the magnification threshold.

The third example shown in FIG. 9C to the planned route obtained from the starting point P _O and destination point P _D included in the presentation route search request, it searches the traveling route similar to this, most mileage therein With respect to the shortest travel route L, the travel route that has a predetermined magnification (for example, N times L (N is a positive number)) or more with respect to the shortest distance L is suppressed from being provided as a presentation route. Or prohibit it. For example, as shown in the figure, when three presented routes (similar routes) are extracted from the planned route, and the travel route with the shortest distance among these three presented routes is presented route 2, A value NL obtained by multiplying the travel distance L of the presented route 2 by a predetermined magnification N is set as a magnification threshold. For example, in step S710, the travel distance of the travel route is determined from among the third travel routes finally extracted. Exclude those that are greater than or equal to the magnification threshold NL. Thereby, it is possible to suppress providing an unintended travel route such as a detour travel route as a presentation route.

Although not shown in FIG. 9C, even if the presented route search request includes one or more waypoints P _W , the obtained route route is also a travel route that passes through this waypoint P _W. Therefore, NL obtained by multiplying the travel distance L of the shortest presentation route by a predetermined magnification N may be set as the magnification threshold. Further, the determination of the reference route from a plurality of presented routes is not limited to the shortest distance, and the number of the same traveling route, that is, the frequency of the traveling route may be highest.

In second and third examples shown in FIGS. 9B and 9C, the planned route and presenting the route obtained from the starting point P _O and destination point P _D included in the presentation route search request (similar route), except the travel path May include the attribute of the travel route. For example, the attribute of the travel route includes whether it is a toll road or a general road. When the attribute of the travel route is included in this way, different magnifications N ₁ and N ₂ may be set for each attribute. In this case, if the retrieved presentation route passes through the toll road, the magnification N ₁ is used to exclude the presentation route having a magnification threshold N ₁ L or more, while the retrieved presentation route is determined as a toll road. For a road that passes through a general road that does not pass, the magnification N ₂ can be used, and a presentation route with a magnification threshold N ₂ L or more can be excluded.

First to third examples shown above in FIG. 9A~ 9C are inhibiting the provision of presentation route equal to or greater than a predetermined threshold value with respect to the "distance relationship" between the departure point P _O and destination point P _D it is a specific means for, which can be replaced with means for inhibiting the provision of presentation route larger than a prescribed threshold value for the "temporal relationship" between the departure point P _O and destination point P _D . That is, for the first example shown in FIG. 9A, the starting point P _O and destination point P _D and the predetermined velocity V a distance L of a straight line connecting included in presentation route search request (V is a constant value) when the vehicle travels at For a travel route that has a predetermined magnification (for example, N times T (N is a positive number)) or more with respect to the travel time T, provision as a presentation route may be suppressed or prohibited. Then, from among the travel route start point of the travel route is present in the starting region R _O in such step S703, excluding those travel time of the travel route is the magnification threshold NT more. As a result, it is possible to suppress providing an unintended travel route such as a travel route that takes too much time (detour in time) as the presentation route.

Incidentally, the travel of the case is not shown in FIG. 9A, if it contains waypoints P _W in presenting the route search request that was traveling on a straight distance connecting the via-point P _W as a starting point P _O at a predetermined speed V the time T _1, via point and travel time linear distance connecting the destination point was also added to the travel time T ₂ of the case where the vehicle travels at a predetermined speed V T _{1 +} T ₂ value multiplied by a predetermined factor N to N (T ₁ + T ₂₎ was set to the magnification threshold, such as in step S703, from among the travel route start point of the travel route is present in the starting region R _O, the travel route of the traveling time ratio threshold N (T 1 ₊ T ₂₎ What is necessary is just to exclude. In addition, when a plurality of waypoints P _W are included, the magnification threshold value may be set similarly.

Similarly, for the second example shown in FIG. 9B, with respect to presenting the route search request is included in the start point P _O and travel time planned route obtained from an object point P _D T, a predetermined magnification (e.g. T N For travel routes that are more than double (N is a positive number), provision as a presentation route may be suppressed or prohibited. Then, in such step S703, from among the travel route start point of the travel route is present in the starting region R _O, excluding those travel time of the travel route is the magnification threshold NT more. As a result, it is possible to suppress providing an unintended travel route such as a travel route that takes too much time (detour in time) as the presentation route.

Similarly, the third example shown in FIG. 9C to the planned route obtained from the starting point P _O and destination point P _D included in the presentation route search request, it searches the traveling route similar thereto, therein With respect to the travel time T of the travel route with the shortest travel time, a travel route that has a predetermined magnification (for example, N times T (N is a positive number)) or more with respect to the shortest time T is used as a presentation route. May be suppressed or prohibited. For example, as shown in the figure, when three presented routes (similar routes) are extracted with respect to the planned route, and the travel route of the shortest time among these three presented routes is the presented route 2, A value NT obtained by multiplying the travel time T of the presented route 2 by a predetermined magnification N is set as a magnification threshold value. For example, in step S710, the travel time of the travel route is extracted from the finally extracted third travel route. Exclude those that are greater than or equal to the magnification threshold NT. As a result, it is possible to suppress providing an unintended travel route such as a travel route that takes too much time (detour in time) as the presentation route.

  The examples shown in FIGS. 10A to 10D are specific examples of limiting the search range when searching for a travel route similar to the planned route. In these fourth to seventh examples, the search range is limited to a rectangular search range.

In the fourth example shown in FIG. 10A, the departure point P _O (or departure region R _O ), the destination point P _D (or destination region R _D ), the departure point P _O and the destination point included in the presented route search request are shown. a planned route obtained from P _D, is to suppress or inhibit the provision of the rectangular search range 1 (or a rectangular search range 2) more than presentation route including. In the figure, the rectangular search range 1 shows a rectangular search range including the planned route and the starting point P _O and destination point P _D, rectangular search range 2, the planned route to the starting area R _O and the destination area R _D Indicates a rectangular search range that includes. Any of the rectangular search ranges 1 and 2 may be set. The starting point P _O and destination point P _D included in the presentation route search _request, and the planned route obtained from these starting points P _O and destination point P _D, because it contains the latitude and longitude information, the latitude and longitude information By extracting the minimum longitude, the maximum longitude, the minimum latitude, and the maximum latitude from the above and connecting them into a rectangle along the latitude and longitude direction, the rectangular search range 1 shown in the figure can be generated. For rectangular search range 2 also departure point P _O and destination point P _D in the latitude and longitude information and respective radii r _O, minimum longitude from the r _D, maximum longitude, it extracts the minimum latitude and maximum latitude, these The rectangular search range 2 shown in the figure can be generated by connecting the rectangles along the latitude and longitude directions.

Then, from among the travel route start point of the travel route is present in the starting region R _O in such step S703, the running route excludes those exceeding the rectangular search range 1 or 2. Accordingly, it is possible to suppress providing an unintended travel route such as a travel route that makes a detour in terms of distance or time as a presentation route.

As in the fourth example, the fifth example shown in FIG. 10B includes the departure point P _O (or departure region R _O ) and the destination point P _D (or destination region R _D ) included in the presented route search request, a planned route obtained from these starting points P _O and destination point P _D, but is intended to suppress or inhibit the provision of the rectangular search range 1 (or a rectangular search range 2) more than presentation route including, rectangular outline There is constituted by parallel or perpendicular line to a straight line connecting the starting point P _O and destination point P _D, differs from the fourth example in that it does not limited to latitude and longitude. In this fifth example, in the figure, the rectangular search range 1 shows a rectangular search range including the planned route and the starting point P _O and destination point P _D, rectangular search range 2, the starting region R _O and purpose A rectangular search range including the area _RD and the planned route is shown, and any of the rectangular search ranges 1 and 2 may be set.

The starting point P _O and destination point P _D included in the presentation route search _request, and the planned route obtained from these starting points P _O and destination point P _D, because it contains the latitude and longitude information, the latitude and longitude information Min longitude, maximum longitude, extracts the minimum latitude and maximum latitude, determining the smallest rectangle enclosing parallel or perpendicular line to a straight line connecting the starting point P _O and destination point P _D as shown them from Thus, the rectangular search range 1 can be generated. For rectangular search range 2 also departure point P _O and destination point P _D in the latitude and longitude information and respective radii r _O, minimum longitude from the r _D, maximum longitude, it extracts the minimum latitude and maximum latitude, these it is possible to generate a square search range 2 shown by connecting rectangular along a parallel or perpendicular line to a straight line connecting the starting point P _O and destination point P _D.

Sixth example shown in FIG. 10C, the similar to the fourth example and fifth example, the starting point P _O contained in presenting the route search request, the destination point P _D, these start point P _O and destination point P _D a planned route obtained from, but is intended to suppress or inhibit the provision of presentation route exceeding the rectangular search range 1 containing, rectangular outline is centered on each of the starting point P _O and destination point P _D is composed of fan-shaped radial line is different from the fourth example and fifth example in that it does not necessarily parallel or perpendicular to the straight line connecting the latitude and longitude and the starting point P _O and destination point P _D. Here, one of the sector radius centered on the starting point P _O, the other sector radius centered on destination point P _D may be different be equal. By equalizing the two fan-shaped radial, since the rectangular search range set becomes rhombic, it can be made uniform range without being biased to one of the starting point P _O and destination point P _D.

The seventh example illustrated in FIG. 10D is an example illustrating a method for setting a rectangular search range in the case where the waypoint search request includes the waypoint _PW . Even when it contains one or more transit point P _W, by treating the via-point P _W equivalent to the starting point P _O and destination point P _D, a fourth example to sixth example of the above-described Similarly, a rectangular search range can be set. That is, the seventh example of FIG. 10D corresponds to an example in which the waypoint P _W is added to the fourth example of FIG. 10A, but the departure point P _O (or the departure area R _O ) and the destination point P _D (or In addition to the destination area R _D ) and the planned route obtained from the departure point P _O and the destination point P _{D, the} rectangular search range 1 (or the rectangular search range 2) including the via point P _W (or the via region R _W ) )And it is sufficient. In the figure, the rectangular search range 1 shows a rectangular search range that includes a transit point P _W and the planned route to the starting point P _O and destination point P _D, rectangular search range 2, the starting region R _O and the destination area R shows a rectangular search range that includes a via region R _W and _D and the planned route. Any of the rectangular search ranges 1 and 2 may be set.

The starting point P _O and destination point P _D and waypoint P _W contained in the presentation route search _request, and the planned route obtained from these starting points P _O and destination point P _D, because it contains the latitude and longitude information, By extracting the minimum longitude, the maximum longitude, the minimum latitude, and the maximum latitude from the latitude / longitude information and connecting them to a rectangle along the latitude / longitude direction, a rectangular search range 1 shown in the figure can be generated. For rectangular search range 2 also latitude and longitude information and respective radii _r O point of departure _{P O} and destination point _{P D} and waypoint _{P W,} r D, the minimum from the _{r W} longitude, maximum longitude, minimum latitude and A rectangular search range 2 shown in the figure can be generated by extracting the maximum latitude and connecting these to a rectangle along the latitude and longitude directions.

Then, from among the travel route start point of the travel route is present in the starting region R _O in such step S703, the running route excludes those exceeding the rectangular search range 1 or 2. Accordingly, it is possible to suppress providing an unintended travel route such as a travel route that makes a detour in terms of distance or time as a presentation route.

In the above-described fourth to seventh examples, instead of the planned route, among the presented routes searched as being similar to the planned route, the shortest distance presented route, the most frequent value presented route, and the minimum power consumption A rectangular range including any of these presentation routes, the departure point P _O (or departure region R _O ), and the destination point P _D (or destination region R _D ) is extracted as a rectangular search range. Also good.

  When the search range when searching for a travel route similar to the planned route is limited, it is not limited to the rectangular search ranges 1 and 2 as shown in FIGS. 10A to 10D. The eighth to ninth examples shown in FIGS. 11A to 11B limit the search range to a range of a predetermined distance in the width direction from the planned route.

In the eighth example shown in FIG. 11A, the departure point P _O (or departure region R _O ), the destination point P _D (or destination region R _D ), the departure point P _O and the destination point included in the presented route search request are shown. It includes a planned route obtained from P _D, the starting point P _{O (or} starting regional R _O) and destination point P _{D (or} target area R _D) and the planned route from the respective predetermined distances m on both sides in the width direction The range is set as the search range. The starting point P _O and destination point P _D included in the presentation route search _request, and the planned route obtained from these starting points P _O and destination point P _D, because it contains the latitude and longitude information, the latitude and longitude information By calculating the position coordinates of the predetermined distance m in the width direction from each of them and connecting them, the search range shown in the figure can be generated.

Then, in step S703 and the like, from the travel routes whose start point of the travel route exists in the departure area R _O , those whose travel route exceeds the search range are excluded. Accordingly, it is possible to suppress providing an unintended travel route such as a travel route that makes a detour in terms of distance or time as a presentation route.

Figure 10B is a ninth embodiment illustrating a case where the planned route obtained from the starting point P _O and destination point P _D are multiple extracted, predetermined in this case, for each of the planned route 1 and planned route 2 in the width direction The range of the distance m is calculated, and the maximum range obtained by combining these is set as the search range.

In the above-described eighth to ninth examples, instead of the planned route, among the suggested routes retrieved as being similar to the planned route, the shortest distance suggested route, the most frequent value suggested route, and the minimum power consumption A rectangular range including any of these presentation routes, the departure point P _O (or departure region R _O ), and the destination point P _D (or destination region R _D ) is extracted as a rectangular search range. Also good.

Returning to step S703 in FIG. 8, the history statistical processing unit 27 includes the set departure region _RO and destination region _RD in the first traveling history information (traveling route) stored in the traveling history storage unit 26. Then, a travel route having a start point and an end point is retrieved, and the retrieved travel route is extracted as a similar route. Specifically, at step S703, the start point from among the accumulated travel routes extracts the travel route existing in the starting region R _O, if present willing the travel route first travel to step S704 The route is temporarily stored, but if it does not exist, it is determined that it is not a similar route, and the process proceeds to step S711.

In performing the process of this step S703, the magnification threshold NL of the first example - the second example of FIG 9A~ Figure 9B as described above, by NT, magnification threshold NL things starting point present in the starting region _{R O.} Travel routes that are greater than NT are excluded and are not temporarily stored as the first travel route. Similarly, by setting the search range in the fourth to ninth examples in FIGS. 10A to 11B, the start point is present in the departure area R _O but the travel route exceeding the search range is excluded, and is temporarily set as the first travel route. Do not remember.

Next, in step S705, a travel route whose end point exists in the destination area _RD is extracted from the first travel route. If it exists, the process proceeds to step S706, and the travel route is temporarily set as the second travel route. If it does not exist, it is determined that the route is not a similar route, and the process proceeds to step S711. Set as similar route. Next, in step S707, a travel route that passes through the transit area RW is extracted from the second travel route, and if it exists, the process proceeds to step S708 to temporarily store the travel route as the third travel route. If it does not exist, it is determined that the route is not similar, and the process proceeds to step S711. If the waypoint PW is not set, the process proceeds to step S708 without performing the process of step S707.

In step S709, it is determined whether or not the search has been completed for all travel routes within the search range. If not completed, the process returns to step S703 to repeat the processes in steps S703 to S709, and if completed, the process returns to step S710. move on. In step S710, the travel route temporarily stored as the third travel route is output as a similar route (presented route). For example, in the example shown in FIG. 7 (B), with respect to the planned route connecting the departure point P _O and destination point P _D, two "similar route 1" and an example that the detected "similar route 2" Show.

In the present embodiment, the radius r _O and the radius r _D that define the size (width) of the departure area R _O and the destination area R _D are set to a predetermined distance (for example, 5 km). Can do. According to the present embodiment, when searching for a similar route in this way, by setting a certain range such as a departure area R _O and a destination area R _D having a predetermined range, the travel history accumulation unit 26 accumulates It is possible to reduce the situation that there is no corresponding similar route in the first travel history information (travel route), and thus it is possible to appropriately set the similar route. Conversely, by limiting this range to a certain range, that is, by not setting an excessively wide range, the search load for similar routes can be reduced and the search time can be shortened.

  Returning to step S403 in FIG. 6, the similar route that has been searched and hit in this way is set as a presentation route. The number of presentation routes is not particularly limited, and may be one or more. When similar routes are detected, all the detected similar routes may be set as the presentation routes, or one of all detected similar routes may be set according to a predetermined condition. Two or more similar routes may be selected and used as the presentation route. Examples of the predetermined condition include a method of selecting a similar route close to the current condition in consideration of conditions such as travel time (season, temperature), use of air conditioner during travel, and the like. Alternatively, a similar route may be selected in consideration of power consumption (for example, a route having the largest and smallest power consumption among the similar routes may be selected).

In step S403, the history statistical processing unit 27 determines that there is no similar route in the first travel history information (travel route) accumulated by the travel history accumulation unit 26, that is, the departure region R _O and If there is no travel route having a start point and an end point in the destination area _RD , the extraction of a similar route is abandoned. When the similar route is abandoned, the fact is temporarily stored by setting a corresponding flag.

In the similar route search process of this example shown in FIG. 8, the following procedure may be adopted in order to reduce the search load (which can also be referred to as search cost such as search time) as much as possible. That is, the starting point and the ending point of the travel route accumulated in the travel history accumulating unit 26 are respectively extracted, the end point sub-database storing the number of data is generated in advance, and the end point is processed before step S703 is processed. Using the end point information of the travel history information accumulated in the database, the number of data N _{O of} the start point (similar start point) existing in the departure area R _O and the end point (similar end point) existing in the destination area R _D ) And the number of data N _D are extracted. In the end point sub-database, starting point information consisting of longitude / latitude information and ending point information are stored separately, and when starting area is specified, starting point information existing within that range is immediately extracted, When the destination area is specified, end point information existing within the range is immediately extracted.

Next, a comparison is made between the number of starting data N _O existing in the extracted starting area R _O and the number of end data N _D existing in the destination area R _D , and the area R having the smaller number of data is compared. It is determined which of _O 1 and _RD is. If the start point data number N _O is smaller than the end point data number N _{D, the} search is started from the departure area as shown in steps S703 and S705 of FIG. 8, otherwise, that is, the end point data number. If N _D is less than the data number N _O starting point it may be and start searching the destination area by reversing the order of steps S703 and S705 in FIG. 8. As described above, the number of data of the end points of the travel data stored in the travel history storage unit 26 is determined, and the corresponding travel data is first extracted for the end points with a small number of data, and the other of the extracted travel data is extracted. If it is determined whether or not the end point is applicable, a similar route can be extracted with a minimum search load.

  Returning to step S404 in FIG. 6, the history statistical processing unit 27 determines whether or not a similar route (presented route) has been determined by the processing in step S403 described above. If the history statistical processing unit 27 determines that the similar route has been determined (step S404 = Yes), the history statistics processing unit 27 proceeds to step S405. On the other hand, if the history statistical processing unit 27 determines that the similar route could not be determined (step S404 = No), the history statistical processing unit 27 proceeds to step S407.

  If it is determined in step S404 that the similar route has been determined, the process proceeds to step S405. In step S405, the history statistical processing unit 27 selects the first travel history information stored in the travel history storage unit 26. The first traveling history information including the similar route is retrieved, and the second traveling history information (the charging via point) stored in the traveling history accumulation unit 26 is associated with the retrieved first traveling history information. The charging via point is extracted from the second traveling history information.

  Subsequently, the process proceeds to step S406, where the history statistical processing unit 27 selects the similar route (presentation) determined in step S403 described above from the first travel history information (power consumption information) stored in the travel history storage unit 26. The power consumption consumed when traveling on the route) is extracted. For example, when the presented route that is a similar route is determined in step S403 described above, the history statistical processing unit 27 extracts the power consumption from the first traveling history information including the similar route.

  If it is determined in step S404 that a similar route (presented route) could not be determined, the process proceeds to step S407. In step S407, the history statistical processing unit 27 described above based on the theoretical performance of the host vehicle A. Power consumption consumed when traveling on the planned route searched in step S401 (hereinafter also referred to as theoretical power consumption) is calculated. Specifically, the history statistical processing unit 27 sets the theoretical power consumption as the multiplication result of the total length of the planned route and the power consumption per unit distance determined in advance, and proceeds to step S408.

  Subsequently, the process proceeds to step S408, and the history statistical processing unit 27 extracts the position of the charging facility C existing in the vicinity of the planned route searched in step S401 described above based on the map information stored in the map information storage unit 25. Then, the process proceeds to step S409. Examples of the charging facility C in the vicinity of the planned route include the charging facility C existing along the planned route and the charging facility C within a set distance (for example, 20 m) from the planned route.

  Next, in step S409, the history statistical processing unit 27 performs a charging via point extraction process (see FIG. 12) based on the remaining battery level acquired in step S402 described above. In the charging via point extraction process, the history statistical processing unit 27 extracts a charging via point to be transmitted (provided) to the transmission source terminal device 2 from the charging via points acquired in step S405 or S408 described above. An example of the transmission source terminal device 2 is the terminal device 2 that is the transmission source of the presentation route search request that triggered the start of the history statistical processing. Further, in the charging via point extraction process, the possibility that the vehicle A cannot reach the destination point is determined, and when it is determined that there is a possibility that the destination point cannot be reached, an unreachable warning is given to warn to that effect. decide.

  FIG. 12 is a flowchart showing a sub-routine of the charging via point extraction process in step S409 of FIG. As shown in FIG. 12, first, in step S501, the history statistical processing unit 27 uses the remaining battery power acquired in step S402 described above as the power consumption extracted in step S406 or S407 described above (hereinafter also referred to as extracted power consumption). ) It is determined whether it is larger. When the history statistical processing unit 27 determines that the remaining battery capacity is greater than the extracted power consumption (step S501 = Yes), the history statistics processing unit 27 proceeds to step S502. On the other hand, when the history statistical processing unit 27 determines that the remaining battery level is equal to or less than the extracted power consumption (step S501 = No), the history statistical processing unit 27 proceeds to step S505.

  If it is determined in step S501 that the remaining battery level is greater than the extracted power consumption, the process proceeds to step S502. In step S502, the history statistical processing unit 27 stores the second travel history stored in the travel history storage unit 26. With reference to the information (charging point), it is determined whether or not there is an actual charging point among the charging points acquired in step S405 or S408 described above. The actual charging point includes the position of the charging facility C where at least one of the plurality of vehicles A has actually charged. When the history statistics processing unit 27 determines that there is a track record charging point (step S502 = Yes), the history statistics processing unit 27 proceeds to step S503.

  If the history statistical processing unit 27 determines that there is no actual charging point (step S502 = No), the history point processing unit 27 ends the charging point extraction process without extracting the charging point. Thereby, the history statistical processing unit 27 has a sufficient remaining battery capacity of the traveling battery 14 and when there is no actual charging via point among the charging via points acquired in step S405 or S408 described above. The information on the actual charging via point is not transmitted (provided) to the transmission source terminal device 2. Since the actual charging point may be a dedicated charging facility for a specific individual or corporation, it is desirable to preferentially extract a facility that is surely a public charging facility by statistical processing. For example, it has a configuration with a separate public charging facility database, and a method of extracting the data at the same location as this data, or a plurality of vehicles (for example, 5 or more) with different names (including corporations and individuals) are the same A method of extracting charging facilities that have a track record of charging at a point can be considered. In addition, when using these data, it is desirable to select the charging facility that is actually available in the expected arrival time zone of the route by giving priority to the available time zone. .

  On the other hand, if it is determined that there is an actual charging via point, the process proceeds to step S503, and in step S503, the history statistical processing unit 27 stores the second traveling history information (the charging via point) accumulated in the traveling history accumulation unit 26. ), The actual charging point is extracted from the charging points acquired in step S405 or S408 described above, and then the charging point extraction process is terminated. Thereby, the history statistical processing unit 27 has a sufficient battery remaining amount of the traveling battery 14 and when there is an actual charging via point among the charging via points acquired in step S405 or S408 described above. Only the information on the actual charging via point is transmitted (provided) to the transmission source terminal device 2.

  If it is determined in step S501 described above that the remaining battery level is equal to or less than the extracted power consumption, the process proceeds to step S504. In step S504, the history statistical processing unit 27 is stored in the map information storage unit 25. Based on the map information, it is determined whether or not the charging facility C exists in the vicinity of the similar route (presented route) determined in step S403 described above. Examples of the charging facility C that exists in the vicinity of the presentation route include the charging facility C that exists along the presentation route and the charging facility C that is within a set distance (for example, 20 m) from the presentation route. When the history statistics processing unit 27 determines that the charging facility C exists in the vicinity of the presentation route (step S504 = Yes), the history statistics processing unit 27 proceeds to step S505. On the other hand, if the history statistical processing unit 27 determines that there is no charging facility C in the vicinity of the presented route (step S504 = No), the history statistical processing unit 27 proceeds to step S506.

  If the presented route cannot be determined in step S403 described above, the history statistical processing unit 27 uses the map route stored in the map information storage unit 25 to search for the planned route searched in step S401 described above. It is determined whether or not the charging facility C exists in the vicinity. If the history statistical processing unit 27 determines that the charging facility C exists in the vicinity of the planned route (step S504 = Yes), the history statistical processing unit 27 proceeds to step S505. On the other hand, if the history statistics processing unit 27 determines that there is no charging facility C in the vicinity of the planned route (step S504 = No), the history statistics processing unit 27 proceeds to step S506.

  If it is determined in step S504 that the charging facility C exists in the vicinity of the presented route, the process proceeds to step S505. In step S505, the history statistical processing unit 27 stores the map information stored in the map information storage unit 25. Based on this, after extracting the position of the charging facility C existing in the vicinity of the similar route (presentation route) (hereinafter also referred to as a recommended nearby charging route), the charging route point extraction process is terminated. When the similar route (presented route) cannot be determined in step S403 described above, the history statistical processing unit 27 exists in the vicinity of the planned route based on the map information stored in the map information storage unit 25. The recommended nearby charging via points are extracted. Thereby, the history statistical processing unit 27, when the remaining battery level of the traveling battery 14 is insufficient and there is a recommended nearby charging via point, only the information of the recommended neighboring charging via point is transmitted from the transmission source terminal. Transmit (provide) to the device 2.

  On the other hand, if it is determined in step S504 that the charging facility C does not exist in the vicinity of the presentation route, the process proceeds to step S506. In step S506, the history statistical processing unit 27 determines to perform an unreachable warning. The charging via point extraction process is terminated. Thereby, the history statistical processing unit 27, when the remaining battery capacity of the traveling battery 14 is insufficient and there is no recommended nearby charging via point, information on the recommended neighboring charging via point (charging via point). Is not transmitted (provided) to the transmission source terminal device 2.

  Returning to FIG. 6, when the charging route extraction process ends, the process proceeds to step S <b> 410, and the history statistical processing unit 27 executes a power consumption correction process (see FIG. 13) based on the power consumption tendency of the driver of the vehicle A. In the power consumption correction process, the history statistics processing unit 27 includes the first driving history information stored in the traveling history storage unit 26 and the first driver ID specified by the driver ID included in the presentation route search request. With reference to the travel history information, power consumption consumed when traveling on a similar route (presented route) is calculated. Subsequently, the history statistical processing unit 27 corrects the power consumption extracted in step S405 or S408 described above based on the calculated power consumption.

  FIG. 13 is a flowchart showing a subroutine of power consumption correction processing in step S410 of FIG. As shown in FIG. 13, first, in step S601, the history statistics processing unit 27 acquires a driver ID (information for specifying a driver) from the received presentation route search request. Subsequently, the history statistics processing unit 27 includes first traveling history information (including the same driver ID as the acquired driver ID) in the first traveling history information accumulated by the traveling history accumulating unit 26 ( Hereinafter, it is determined whether there is transmission source travel history information). If the history statistics processing unit 27 determines that there is transmission source travel history information (step S601 = Yes), the history statistics processing unit 27 proceeds to step S603. On the other hand, if the history statistics processing unit 27 determines that there is no transmission source travel history information (step S601 = No), the history statistics processing unit 27 proceeds to step S602.

  If it is determined in step S601 that there is transmission source travel history information, the process proceeds to step S602. In step S602, the history statistical processing unit 27 directly corrects the power consumption calculated in step S406 or S407 described above. The power consumption is corrected (hereinafter also referred to as “corrected power consumption”), and the power consumption correction process is terminated. Thereby, the history statistical processing unit 27, when there is no transmission source travel history information in the first travel history information stored in the travel history storage unit 26, the consumption calculated in step S406 or S407 described above. The power information is transmitted (provided) to the transmission source terminal device 2 as it is.

  On the other hand, if it is determined in step S601 that there is no transmission source travel history information, the process proceeds to step S603. In step S603, the history statistical processing unit 27 stores the transmission source travel history stored in the travel history storage unit 26. It is determined whether or not the information (travel route) includes the same travel route (hereinafter also referred to as the same travel route) as the similar route extracted in step S403 described above. When the history statistical processing unit 27 determines that there is the same travel route (step S603 = Yes), the history statistical processing unit 27 proceeds to step S604. On the other hand, when the history statistical processing unit 27 determines that there is no identical travel route (step S603 = No), the history statistical processing unit 27 proceeds to step S606. Note that the same travel route may be any route that can be determined to be the same as the similar route extracted in step S403 described above, and there may be a different portion as long as the amount can be determined as an error range.

  If it is determined in step S603 that there is the same travel route, the process proceeds to step S604. In step S604, the history statistical processing unit 27 selects the transmission source travel history information stored in the travel history storage unit 26. The power consumption consumed when traveling on the same travel route is extracted. Subsequently, the history statistical processing unit 27 sets the extracted power consumption as correction power consumption.

  In step S605, the history statistical processing unit 27 corrects the power consumption calculated in step S406 or S407 described above based on the power consumption for correction calculated in step S604 described above. As a power consumption correction method, for example, a method of replacing power consumption with power consumption for correction, a method of calculating an average value of power consumption and power consumption for correction, and a difference between power consumption b and power consumption for correction a There is a method of expressing a ± c using c. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and then ends the power consumption correction process. As a result, the history statistical processing unit 27 consumes power consumed when traveling on the same travel route when the same travel route exists in the transmission source travel history information stored in the travel history storage unit 26. And the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, when it is determined in step S603 described above that there is no same travel route, the process proceeds to step S606, and in step S606, the history statistical processing unit 27 stores the transmission source travel history stored in the travel history storage unit 26. It is determined whether or not there is a similar type travel route in the information (travel route). As the similar type travel route, for example, there is a travel route having the same or similar road type as the similar route (presented route) determined in step S403 described above. If the similar route (presented route) cannot be determined in step S403 described above, the planned route searched in step S401 described above is set as the similar type travel route. When the history statistics processing unit 27 determines that there is a similar type travel route (step S606 = Yes), the history statistics processing unit 27 proceeds to step S607. On the other hand, when the history statistics processing unit 27 determines that there is no similar type travel route (step S606 = No), the history statistics processing unit 27 proceeds to step S610.

  If it is determined in step S606 that there is a similar type travel route, the process proceeds to step S607. In step S607, the history statistical processing unit 27 refers to the transmission source travel history information stored in the travel history storage unit 26. Then, the power consumption per unit distance of the similar type travel route (hereinafter also referred to as the similar type power consumption rate) is calculated.

  In step S608, the history statistical processing unit 27 multiplies the similar type power consumption rate calculated in step S607 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S609, the history statistical processing unit 27 corrects the power consumption calculated in step S406 or S407 described above based on the power consumption for correction calculated in step S608 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thereby, the history statistical processing unit 27 corrects the power consumption with the similar type power consumption rate when there is a similar type travel route in the transmission source travel history information accumulated in the travel history accumulation unit 26. Then, the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S606 described above that there is no similar type travel route, the process proceeds to step S610. In step S610, the history statistical processing unit 27 stores the transmission source travel stored in the travel history storage unit 26. It is determined whether or not there is a similar distance travel route in the history information (travel route). As the similar distance travel route, for example, there is a travel route having the same or similar total length as the similar route (presented route) determined in step S403 described above. If the similar route (presented route) cannot be determined in step S403 described above, the planned route searched in step S401 described above is set as the similar distance travel route. For example, the history statistical processing unit 27 has a difference from the total length of the presented route in the transmission source travel history information (travel route) stored in the travel history storage unit 26 that is less than a set value (for example, ± 100 m). It is determined whether there is a travel route. When the history statistics processing unit 27 determines that there is a similar distance travel route (step S610 = Yes), the history statistics processing unit 27 proceeds to step S611. On the other hand, when the history statistics processing unit 27 determines that there is no similar distance travel route (step S610 = No), the history statistics processing unit 27 proceeds to step S614.

  If it is determined in step S610 that there is a similar distance travel route, the process proceeds to step S611. In step S611, the history statistical processing unit 27 refers to the transmission source travel history information stored in the travel history storage unit 26. Then, power consumption per unit distance of the similar distance travel route (hereinafter also referred to as similar distance power consumption rate) is calculated.

  In step S612, the history statistical processing unit 27 multiplies the similar distance power consumption rate calculated in step S611 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S613, the history statistical processing unit 27 corrects the power consumption calculated in step S406 or S407 described above based on the power consumption for correction calculated in step S612 described above. The power consumption correction method is the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thus, the history statistical processing unit 27 corrects the power consumption with the similar distance power consumption rate when there is a similar distance travel route in the transmission source travel history information stored in the travel history storage unit 26. Then, the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S610 described above that there is no similar distance travel route, the process proceeds to step S614. In step S614, the history statistical processing unit 27 stores the transmission source travel stored in the travel history storage unit 26. It is determined whether or not there is a similar average speed travel route in the history information (travel route). As the similar average speed travel route, for example, there is a travel route having the same or similar average speed as the similar route (presented route) determined in step S403 described above.

  If the similar route (presented route) cannot be determined in step S403 described above, the planned route searched in step S401 described above is set as the similar average speed travel route. For example, the history statistical processing unit 27 has a difference from the average speed of the presented route in the transmission source travel history information (travel route) stored in the travel history storage unit 26 as a set value (for example, ± 5 km / h). ) Determine whether there are less travel routes. If the history statistical processing unit 27 determines that there is a similar average speed travel route (step S614 = Yes), the history statistical processing unit 27 proceeds to step S615. On the other hand, when the history statistical processing unit 27 determines that there is no similar average speed travel route (step S614 = No), the history statistical processing unit 27 proceeds to step S618.

  If it is determined in step S614 that there is a similar average speed travel route, the process proceeds to step S615. In step S615, the history statistical processing unit 27 displays the transmission source travel history information stored in the travel history storage unit 26. Referring to this, power consumption per unit distance of the similar average speed travel route (hereinafter also referred to as similar average speed power consumption rate) is calculated.

  Subsequently, the process proceeds to step S616, where the history statistical processing unit 27 multiplies the similar average speed power consumption rate calculated in step S615 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S617, the history statistical processing unit 27 corrects the power consumption calculated in step S406 or S407 described above based on the power consumption for correction calculated in step S616 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thereby, the history statistical processing unit 27 calculates the power consumption at the similar average vehicle speed power consumption rate when there is a similar average speed travel route in the transmission source travel history information accumulated by the travel history accumulation unit 26. The corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S614 described above that there is no similar average speed travel route, the process proceeds to step S618. In step S618, the history statistical processing unit 27 stores the transmission source stored in the travel history storage unit 26. With reference to the travel history information, an average value of power consumption per unit distance (hereinafter also referred to as an average power consumption rate) of the travel route of all transmission source travel history information is calculated.

  Subsequently, the process proceeds to step S619, and the history statistical processing unit 27 multiplies the average power consumption rate calculated in step S618 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S620, the history statistical processing unit 27 corrects the power consumption calculated in step S406 or S407 described above based on the power consumption for correction calculated in step S619 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. As a result, the history statistical processing unit 27 corrects the power consumption with the average power consumption rate when all the determinations of the above-described steps S603, S606, S610, and S614 are “No”, and the corrected consumption The power is transmitted (provided) to the transmission source terminal device 2.

  Returning to FIG. 6, when the power consumption correction process is completed, the process proceeds to step S <b> 411, and the history statistics processing unit 27 determines the similar route (presentation route) determined in step S <b> 403 described above, the charging via point extracted in step S <b> 409 described above, After transmitting (providing) the power consumption information corrected in step S410 to the transmission source terminal device 2, the travel history statistical processing is terminated. Note that if the presented route cannot be determined in step S403 described above, the history statistics processing unit 27 determines the planned route searched in step S401 described above, the charging via point extracted in step S409 described above, and step S407 described above. The information on the power consumption (theoretical power consumption) calculated in step 1 is transmitted.
