Description

  The present invention relates to a travel guidance device and a computer program for performing travel guidance of a user who moves to a destination.

  2. Description of the Related Art In recent years, a vehicle is often equipped with a navigation device that provides travel guidance for a vehicle and enables a driver to easily reach a desired destination. Here, the navigation device means that the current position of the vehicle is detected by a GPS receiver or the like, and map data corresponding to the current position is obtained through a recording medium such as a DVD-ROM or HDD or a network and displayed on a liquid crystal monitor. It is a device that can do. Further, such a navigation device is provided with a route search function for searching for a recommended route from the vehicle position to the destination when a desired destination is input, setting the searched recommended route as a guidance route, and displaying the recommended route. A guidance route is displayed on the screen, and voice guidance is provided when approaching an intersection or the like, so that the user is reliably guided to a desired destination. In recent years, some mobile phones, smartphones, tablet terminals, personal computers, and the like have functions similar to those of the navigation device.

  Furthermore, conventionally, when performing travel guidance along the guide route, the travel history of the user's travel in the past is provided as a comparison target to be compared with the travel of the current vehicle. For example, in Japanese Patent Application Laid-Open No. 2007-114147, while the past traveling history of the vehicle is stored, when the vehicle travels along the guide route, if there is a traveling history traveling on the same route in the same time zone, It describes a technique of calculating an average vehicle speed of those traveling histories and displaying a virtual own vehicle symbol that moves on a guide route at the calculated average vehicle speed on a map image.

JP 2007-114147 A (pages 12-13, FIG. 3)

  Here, in the technique of Patent Document 1, in order to display a virtual own vehicle symbol, at least one or more traveling histories of traveling on the same route as the guide route targeted for traveling guidance are required. Therefore, there is a problem that even if there is a traveling history with the same destination, if there is no traveling history in which the route traveled completely matches the guidance route, the traveling history cannot be guided.

  On the other hand, if a guidance route, that is, a traveling history that does not completely match the planned traveling route that the vehicle is to travel this time is also included in the guidance target, it is difficult to compare the traveling history of the current vehicle with the guided traveling history. A new problem arises.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described conventional problems, and is intended for a case where a user moves to a destination and there is no movement history of the same route as the user's planned route. It is another object of the present invention to provide a travel guidance device and a computer program that can guide a user as a comparison target in an appropriate mode that makes it easy to compare the travel histories of users heading for the same destination.

In order to achieve the above object, a first movement guidance device according to the present invention associates a destination setting means for setting a destination, a setting history of a destination of a user, and a movement history of the user with respect to the set destination. History storage means for storing in a storage medium by means of a storage device, a planned travel route obtaining means for obtaining a planned travel route of a user, and a history acquisition for obtaining the travel history having the same point as the planned travel route as a destination from the storage medium. Means, and when the user starts moving along the expected movement route, the user's virtual moving toward the destination along a history route specified by the movement history acquired by the history acquisition means. has a virtual position display means for displaying the position, wherein the virtual position indicating means, moves on the movement scheduled route a on period of the history path that does not overlap with the moving prediction path Among the user point within a predetermined distance, displaying a virtual position of the user to be moved toward the destination the point of most departure side as the movement start point.
In addition, the second movement guidance device according to the present invention stores a destination setting means for setting a destination, a setting history of the destination of the user and a movement history of the user with respect to the set destination in a storage medium in association with each other. A history storage unit for storing, a planned route acquisition unit for acquiring a planned route of the user, a history acquisition unit for acquiring the travel history having the same point as the planned route as a destination from the storage medium, When the user starts moving along the planned movement route, the virtual position of the user moving toward the destination is displayed along the history route specified by the movement history acquired by the history acquisition unit. Virtual position display means, comprising: virtual position display means; and path length obtaining means for obtaining a path length from a point at which the user starts moving on the planned movement path to a destination. Means displays the virtual position of the user to be moved toward the destination the point spaced the history path on the A and the path length along the history path from the destination only as the moving start point.

Further, the computer program according to the present invention is a program for comparing a user's movement guide with a past movement history. Specifically, a computer, a destination setting means for setting a destination, a history storage means for storing in a storage medium in association with the setting history of the destination of the user and the movement history of the user to the set destination, A scheduled travel route obtaining unit that obtains a scheduled travel route of the user, a history obtaining unit that obtains the travel history having the same point as the scheduled travel route as a destination from the storage medium, Virtual position display means for displaying a virtual position of the user moving toward a destination along a history path specified by the movement history acquired by the history acquisition means, when the movement is started along; Function. In addition, the virtual position display means is a section on the section of the history route that does not overlap with the planned movement route and within a predetermined distance from a user who moves on the planned movement route, among the points closest to the departure point. A virtual position of the user moving toward the destination is displayed as a movement start point.

According to the first movement guidance device and the computer program of the present invention having the above-described configuration, when the user moves to the destination, the same route may be used regardless of whether the route is the same as the user's planned route. The history route of the user who has traveled to the destination in the past is acquired from the storage medium, and the virtual position of the user moving to the destination along the history route is displayed. Even when there is no moving history that has been moved, it is possible to guide the moving history of the user heading to the same destination as a comparison target in an appropriate manner that is easy to compare. In addition, since the movement start point at which the movement of the virtual position is started is corrected to a position corresponding to the position of the user who moves on the planned movement route, even if the departure place of the planned movement route and the history route is different, It is possible to easily compare the planned route and the history route. Then, the user can select a more appropriate route to the destination by referring to the guided comparison result. In addition, even when the departure point of the planned route and the departure point of the history route are far from each other, the movement of the virtual position can be started from a point close to the route that the user moves, so that the planned movement route and the history route can be easily set. Can be compared with In addition, by setting the movement start point on the departure place side as much as possible, it is possible to compare the planned movement route and the history route in a longer period.
On the other hand, according to the second movement guide device, even when the planned movement route and the history route are routes having greatly different path lengths and shapes, the movement start position of the virtual position is determined by the movement distance to the destination. By correcting the distance so as to be the same as the planned travel route of the user, it is possible to compare the planned travel route and the history route using the order of arrival at the destination.

Then, the navigation ECU 13 calculates the rotation speed and the moving distance of the drive wheels by counting the generated pulses. It is not necessary for the navigation device 1 to include all of the above four types of sensors, and the navigation device 1 may be configured to include only one or a plurality of types of these sensors.

  In addition, the data recording unit 12 reads an external storage device and a hard disk (not shown) as a recording medium, a map information DB 31, a driving history DB 32, a predetermined program, and the like recorded on the hard disk, and stores predetermined data in the hard disk. A recording head (not shown) which is a driver for writing. Note that the data recording unit 12 may include a flash memory, a memory card, or an optical disk such as a CD or DVD instead of the hard disk. The map information DB 31 and the travel history DB 32 may be stored in an external server, and the navigation device 1 may acquire the information through communication.

  Here, the map information DB 31 displays, for example, link data 33 relating to roads (links), node data 34 relating to node points, search data 35 used for processing relating to route search, point data relating to points such as facilities, and a map. Storage means for storing map display data, intersection data relating to each intersection, search data for searching for points, and the like.

  Further, as the search data 35, various data used in a route search process for searching for a route from a departure place (for example, the current position of the vehicle) to a set destination as described later are recorded. Specifically, costs such as a numerical value of an appropriate degree as a route to an intersection (hereinafter referred to as an intersection cost), costs such as a numerical value of an appropriate degree as a route to a link constituting a road (hereinafter referred to as a link cost), and the like. Cost calculation data used to calculate a search cost is stored.

Here, the intersection cost is set for each node corresponding to the intersection included in the route for which the search cost is to be calculated, and the presence / absence of a traffic light, the traveling route of the own vehicle when passing through the intersection (that is, straight ahead, right turn, and left turn) The value is calculated by (type).
The link cost is set for each link included in the route for which the search cost is to be calculated. Based on the link length, the link attributes, road type, road width, number of lanes, traffic conditions, and the like are considered. Is calculated.

  On the other hand, the travel history DB 32 is storage means for accumulating and storing past travel histories of the vehicle (user). Specifically, the history of the detection points (position coordinates) of the current position of the vehicle with the passage of time from when the destination is set by the navigation device 1 to when the vehicle arrives at the destination is detected. The time is stored in association with the time (ie, the time at which the vehicle is located at each detection point). Further, the travel history also stores the destination set in the navigation device 1 at the time of traveling (that is, the destination of the travel history) in association with the travel history. Note that a configuration may be adopted in which the elapsed time from the departure time is stored in association with the time at which each detection point is detected.

  In addition, the traveling history when the destination is not set in the navigation device 1 may be stored. In this case, for example, the history of the detection points of the current position of the vehicle with the passage of time from when the ACC power supply (accessory power supply) is turned on (or the engine is turned on) to when the ACC power supply is turned off (or the engine is turned off) is stored. Is stored in association with the time at which each detection point is detected. Further, a point where the ACC power is turned off is associated as a destination.

  Here, FIG. 2 is a diagram showing an example of the travel history of the user stored in the travel history DB 32. FIG. 2 shows a traveling history when the vehicle has departed from the departure place 51 at 9 o'clock and traveled to the destination 52. In the example shown in FIG. 2, the position coordinates of the detection points 53 of the current position of the vehicle when the vehicle has traveled from the departure point 51 to the destination 52 are associated with the time at which each detection point 53 was detected. Is stored as a travel history of travel to the destination 52. In the example shown in FIG. 2, the current position of the vehicle is detected at an interval of 5 seconds, but the time interval of the detection can be changed as appropriate.

  Then, when performing navigation guidance of the vehicle as described later, the navigation ECU 13 guides a traveling history traveling to the same destination among the traveling histories stored in the traveling history DB 32 as a comparison target (FIG. 8). , FIG. 9).

  On the other hand, a navigation ECU (Electronic Control Unit) 13 is an electronic control unit that controls the entire navigation device 1, and includes a CPU 41 as an arithmetic device and a control device, and a working memory when the CPU 41 performs various arithmetic processes. RAM 42 for storing route data when a route is searched, a control program, a running history storage processing program (see FIG. 3) and a running guidance processing program (see FIG. 4). ), Etc., and an internal storage device such as a flash memory 44 for storing a program read from the ROM 43. The navigation ECU 13 has various means as a processing algorithm. For example, the destination setting means sets a destination. The history storage unit stores the destination setting history of the user and the traveling history of the user with respect to the set destination in the traveling history DB 32 in association with each other. The scheduled travel route acquisition means acquires a scheduled travel route of the user. The history acquisition unit acquires, from the travel history DB 32, a travel history having the same point as the planned travel route as the destination. The virtual position display means is, when the user starts traveling along the planned travel route, the virtual position of the user moving toward the destination along the route specified by the travel history acquired by the history acquisition means. Is displayed.

  The operation unit 14 is operated when inputting a departure place as a travel start point and a destination as a travel end point, and has a plurality of operation switches (not shown) such as various keys and buttons. Then, the navigation ECU 13 performs control to execute various corresponding operations based on a switch signal output when each switch is pressed or the like. The operation unit 14 may have a touch panel provided on the front of the liquid crystal display 15. Further, a microphone and a voice recognition device may be provided.

  In addition, the liquid crystal display 15 displays a map image including roads, traffic information, operation guidance, operation menus, key guidance, a guidance route from the departure place to the destination, guidance information along the guidance route, news, weather forecast, Time, mail, television programs, etc. are displayed. In particular, in the first embodiment, when traveling guidance of a vehicle along a guidance route is performed, the traveling history of traveling to the same destination in the past is also displayed on the liquid crystal display 15. Note that a HUD or HMD may be used instead of the liquid crystal display 15.

  Further, the speaker 16 outputs voice guidance for guiding traveling along the guidance route based on an instruction from the navigation ECU 13 and guidance of traffic information.

  The DVD drive 17 is a drive that can read data recorded on a recording medium such as a DVD or a CD. Then, based on the read data, reproduction of music and video, updating of the map information DB 31 and the like are performed. Note that a card slot for reading and writing a memory card may be provided instead of the DVD drive 17.

  The communication module 18 is a communication device for receiving traffic information, probe information, weather information, and the like transmitted from a traffic information center, for example, a VICS center, a probe center, or the like, and corresponds to, for example, a mobile phone or a DCM. .

  Next, a running history storage processing program executed by the CPU 41 in the navigation device 1 having the above configuration will be described with reference to FIG. FIG. 3 is a flowchart of a traveling history storage processing program according to the first embodiment. Here, the traveling history storage processing program is a program that is executed after the ACC power supply (accessory power supply) of the vehicle is turned on, and stores the traveling history of the vehicle. The program shown in the flowchart of FIG. 3 below is stored in the RAM 42 or the ROM 43 provided in the navigation device 1 and executed by the CPU 41.

  First, in the traveling history storage processing program, in step (hereinafter abbreviated as S) 1, the CPU 41 determines whether or not a guidance route is set in the navigation device 1. Note that the guide route is a recommended route from the departure point to the destination set by the navigation device 1, and is searched using, for example, a known Dijkstra method.

  When it is determined that the guidance route is set in the navigation device 1 (S1: YES), the process proceeds to S2. On the other hand, when it is determined that the guidance route is not set in the navigation device 1 (S1: NO), the traveling history storage processing program ends.

  Next, in S2, the CPU 41 acquires the guidance route set by the navigation device 1. In the first embodiment, a point or a facility set as a destination of a guide route is acquired. When a stopover is set, a point or facility set as a stopover may be acquired.

  Subsequently, in S3, the CPU 41 acquires the current position of the vehicle based on the detection result of the current position detection unit 11. Specifically, position coordinates on a map indicating the current position of the vehicle are acquired. When detecting the current position of the vehicle, a map matching process for matching the current position of the vehicle with the map data is also performed. Further, the current position of the vehicle may be determined using precision location technology. Here, the high-accuracy location technology means that a white line or road surface paint information captured from a camera behind the vehicle is detected by image recognition, and further, the white line or road surface paint information is compared with a map information DB stored in advance to drive the vehicle. This technology enables detection of lanes and highly accurate vehicle positions. The details of the high-accuracy location technology are already known and will not be described.

  Thereafter, in S4, the CPU 41 temporarily stores the position coordinates of the current position of the vehicle detected in S3 in a storage medium such as a memory in association with the time at which the current position of the vehicle is detected. Note that a configuration may be adopted in which the elapsed time from the departure time is stored in association with the time at which the current position of each vehicle is detected.

  Subsequently, in S5, the CPU 41 determines whether or not the vehicle has arrived at the destination of the guide route acquired in S2.

  If it is determined that the vehicle has arrived at the destination of the guide route acquired in S2 (S5: YES), the process proceeds to S6. On the other hand, when it is determined that the vehicle has not arrived at the destination of the guidance route acquired in S2 (S5: NO), the process returns to S3. Then, the processes of S3 and S4 are repeatedly executed at predetermined time intervals (for example, every 5 seconds) until the vehicle arrives at the destination.

  In S6, the CPU 41 stores the coordinate sequence and the time accumulated and stored in S4 in the travel history DB 32 as a travel history in association with the destination acquired in S2. As a result, the history of the detection points (position coordinates) of the current position of the vehicle with the lapse of time from when the navigation device 1 sets the destination to when the vehicle arrives at the destination is determined by the time at which each detection point was detected ( That is, the time is stored in the travel history DB 32 in association with the time at which the vehicle is located at each detection point (see FIG. 2). When a stopover is set, the stopover may be stored in association with the stopover.

  In the first embodiment, the travel history when the destination is set in the navigation device 1 is stored. However, the travel history when the destination is not set in the navigation device 1 is also stored. It is possible to In this case, for example, it is determined whether or not the ACC power is turned on (or the engine is turned on) in S1, and whether or not the ACC power is turned off (or the engine is turned off) is determined in S5. Further, a point where the ACC power is turned off is associated as a destination.

  Further, the running history storage processing program may be configured to be executed only in a state where the user has previously selected to store the running history on the setting screen of the navigation device 1. Further, a configuration may be adopted in which the user is allowed to select whether or not to leave the current travel history in the travel history DB 32 when the vehicle arrives at the destination.

  Next, a driving guidance processing program executed by the CPU 41 in the navigation device 1 will be described with reference to FIG. FIG. 4 is a flowchart of the travel guidance processing program according to the first embodiment. Here, the traveling guidance processing program is a program that is executed after a predetermined operation is performed on the navigation device 1 by the user, and sets a guidance route and performs traveling guidance of the vehicle based on the set guidance route. 4 is stored in the RAM 42 or the ROM 43 of the navigation device 1 and executed by the CPU 41.

  First, in the travel guidance processing program, in S11, the CPU 41 reads the travel history stored in the travel history DB 32. Note that all the traveling histories stored in the traveling history DB 32 may be read, or only the traveling histories within a predetermined period (for example, the latest one month) may be read.

  Next, in S12, the CPU 41 displays a list of destinations included in the travel history read from the travel history DB 32 in S11 on the liquid crystal display 15. As described above, the traveling history stores the history of the detection points of the current position of the vehicle in association with the destination set in the navigation device 1 at that time. That is, what is displayed in S12 is the destination of the route on which the user has traveled in the past, more specifically, the destination set in the navigation device 1 in the past.

  Here, FIG. 5 is a view showing a destination list screen 61 displayed on the liquid crystal display 15 in S12. As shown in FIG. 5, the destination list screen 61 is provided with an information display space 62 for displaying a list of destination names of routes on which the user has traveled in the past. The information display space 62 also displays the date and time when the corresponding travel history was created, that is, the date and time when the vehicle traveled to the displayed destination. Further, the names of destinations displayed in the information display space 62 are displayed in the order in which the travel histories are created. In addition, since the name of the destination is displayed in the information display space 62 for each traveling history, a plurality of names of the same destination may be displayed (for example, in FIG. Two are displayed). Although only the final destination is displayed in the example shown in FIG. 5, if there is a waypoint, the waypoint may also be displayed.

  A scroll bar 63 is arranged beside the information display space 62. Then, by operating the scroll bar 63 up and down, the user can scroll the name of the destination displayed in the information display space 62 and switch to another name. Further, when the user selects any destination name displayed in the information display space 62 as described later, the facility or point corresponding to the selected destination name is set as the destination of the navigation device 1, The running history can be displayed.

  Subsequently, in S13, the CPU 41 determines whether or not a destination setting operation has been performed on the destination list screen 61 displayed in S12. Here, as shown in FIG. 6, when an operation of touching any destination name displayed in the information display space 62 of the destination list screen 61 is accepted, the destination setting button 64 and the destination setting button 64 are displayed in the information display space 62. A history display button 65 is newly displayed. Then, when an operation of further touching the destination setting button 64 is received while the destination setting button 64 and the history display button 65 are displayed, a facility or point corresponding to the touched destination name is navigated as described later. The destination of the device 1 is set. On the other hand, when an operation of touching the history display button 65 is received, a travel history corresponding to the touched destination name is displayed on the liquid crystal display 15 as described later.

  If it is determined that the destination setting operation has been performed on the destination list screen 61 displayed in S12 (S13: YES), that is, if it is determined that the destination setting button 64 has been operated, The process moves to S16. On the other hand, if it is determined that the destination setting operation has not been performed on the destination list screen 61 displayed in S12 (S13: NO), the process proceeds to S14.

  In S14, the CPU 41 determines whether or not a browsing operation of the travel history has been performed on the destination list screen 61 displayed in S12. Specifically, when an operation of touching the history display button 65 shown in FIG. 6 is received, it is determined that the browsing operation of the travel history has been performed.

  If it is determined that the browsing operation of the travel history has been performed on the destination list screen 61 displayed in S12 (S14: YES), that is, if it is determined that the history display button 65 has been operated, the process proceeds to S15. Move to. On the other hand, if it is determined that the browsing operation of the travel history has not been performed on the destination list screen 61 displayed in S12 (S14: NO), the process returns to S13.

  In S15, the CPU 41 reads a travel history corresponding to the name of the destination selected by the user from the travel history DB 32, and displays a route (hereinafter, referred to as a history route) of the vehicle included in the read travel history on the liquid crystal display 15. indicate. Note that the history route is a route indicating what route the vehicle has traveled to the destination in the past, and the history of the detection points (position coordinates) of the current position of the vehicle included in the travel history is time-series. The line segment connected by is applicable. Here, FIG. 7 is a diagram showing an example of the history guidance screen 70 in which the history route is displayed on the liquid crystal display 15 in S15. The history guidance screen 70 displays a map image 71 around the history route, a history route 72, a destination 73 of the history route 72, and a vehicle position mark 74 indicating the current position of the vehicle matched on the map. You. In the example shown in FIG. 7, the current position of the vehicle coincides with the departure point of the history route 72, but may not coincide. Then, by referring to the history guidance screen 70, the user can grasp the past traveling history of the vehicle.

  On the other hand, in S16, the CPU 41 sets the facility or point corresponding to the destination name selected by the user as the destination of the navigation device 1, and searches for a recommended route from the departure point to the set destination. Execute Note that the departure place may be the current position of the vehicle or an arbitrary point designated by the user. Specifically, based on the link data 33, the node data 34, the search data 35, and the like, a link cost that quantifies an appropriate degree as a route to a link (road) or an appropriate degree as a route to an intersection (node) is determined. A numerical intersection cost, a toll cost that quantifies the degree of cost required for traveling, and the like are calculated, and a search for a recommended route is performed using the calculated search costs. For example, using a known Dijkstra method, a route with the minimum total cost value is set as a recommended route. It should be noted that the route search processing using the Dijkstra method is already known, and thus the details are omitted. In addition to the recommended route, a search may be made for other candidate routes (for example, routes searched with priority on distance, general road, or toll road) with different search conditions. If the travel history corresponding to the destination name selected by the user includes a stopover, a stopover is set in addition to the destination, and a route via the stopover is searched. May be.

  Subsequently, in S17, the CPU 41 sets the route searched in the route search process in S16 as a guide route (scheduled movement route) as a target of travel guidance by the navigation device 1. When there are a plurality of searched routes, the route selected by the user's selecting operation is set as the guide route.

  Next, in S18, the CPU 41 reads, from the travel history DB 32, a travel history corresponding to the name of the destination selected by the user on the destination list screen 61 (FIG. 6). Note that the recommended route to the destination changes variously depending on the position of the departure place and the route search condition even if the destination is the same. Therefore, the traveling history read from the traveling history DB 32 in S18 is not necessarily the traveling history of traveling on the same route as the guide route set in S17. This is a traveling history that satisfies at least the condition of being the same destination as the guide route.

  Subsequently, in S19, the CPU 41 performs a movement start point setting process described later. The movement start point setting process is a process of setting the movement start point (initial position) of the virtual position in the case of indicating the virtual position of the vehicle moving to the destination along the history route (S21, S26) as described later. It is. Further, the timing for starting the movement of the virtual position is also set.

  Thereafter, in S20, the CPU 41 displays, on the liquid crystal display 15, the history route included in the travel history read from the travel history DB 32 in S18, together with the guide route set in S17. Note that the history route is a route indicating what route the vehicle has traveled to the destination in the past, and the history of the detection points (position coordinates) of the current position of the vehicle included in the travel history is time-series. The line segment connected by is applicable.

  Further, in S21, the CPU 41 displays the own vehicle position mark indicating the current position of the vehicle and the virtual position mark indicating the virtual position of the vehicle moving toward the destination along the history path on the liquid crystal display 15, respectively. Note that the initial position where the virtual position mark is displayed is the movement start point set in S19. Note that the movement start point is not always the departure point of the history route. Here, FIG. 8 is a diagram showing an example of the travel guidance screen 75 immediately after the guidance route, the history route, the own vehicle position mark, and the virtual position mark are displayed on the liquid crystal display 15 in S20 and S21. The travel guide screen 75 includes a map image 71 around the own vehicle position, a history route 72, a guide route 76, an own vehicle position mark 74 indicating the current position of the vehicle matched on the map, a virtual position mark 77, Is displayed.

  In the example shown in FIG. 8, the movement start point of the virtual position is different from the departure point of the history route. In the example shown in FIG. 8, the current position of the vehicle (the departure point of the guide route) does not coincide with the movement start point of the virtual position, but may coincide. If the current position of the vehicle coincides with the movement start point of the virtual position, the own vehicle position mark 74 and the virtual position mark 77 are displayed at the time of guidance start. Then, by referring to the travel guide screen 75, the user can grasp the past travel history of the vehicle heading for the same destination as compared with the guide route. The virtual position mark 77 may be displayed at a point in time when the movement start timing of the virtual position is satisfied (S24: YES), as described later.

  Thereafter, in S22, the CPU 41 starts traveling guidance of the vehicle based on the guidance route set in S17. For example, when the guidance intersection approaches in the forward direction of the vehicle, guidance for turning left or right at the guidance intersection is performed using the liquid crystal display 15 or the speaker 16.

  Next, in S23, the CPU 41 determines whether or not the vehicle has started moving from the initial position (the position when the guide route is set). The determination as to whether the vehicle has started moving may be made by determining that the vehicle has started moving when the position coordinates of the vehicle detected by the GPS 21 at predetermined intervals are displaced from the previous detected position. Alternatively, the determination may be made using the detection result of the vehicle speed sensor 22.

  When it is determined that the vehicle has started moving from the initial position (S23: YES), the process proceeds to S24. On the other hand, when it is determined that the vehicle has not started moving from the initial position (S23: NO), the process stands by until it is determined that the vehicle has started moving.

  In S24, the CPU 41 determines whether or not it is time to start moving the virtual position. Here, the timing of starting the movement of the virtual position is set in S19. Specifically, when there is a movement start point of the virtual position on the guide route, it is the timing when the vehicle reaches the movement start point of the virtual position. On the other hand, when there is no movement start point of the virtual position on the guide route, it is the timing when the vehicle reaches the point closest to the movement start point of the virtual position on the guide route. As a result, even if the departure place of the guide route and the departure place of the history route are separated as described later, the virtual position starts moving from the same position as or close to the current position of the vehicle, Both can be easily compared.

  Then, when it is determined that it is time to start moving the virtual position (S24: YES), the process proceeds to S26. On the other hand, when it is determined that the timing to start moving the virtual position has not come (S24: NO), the process proceeds to S25.

  In S25, the CPU 41 detects the displacement of the current position of the vehicle by the current position detection unit 11, while displaying the own vehicle position mark indicating the current position of the vehicle displayed on the liquid crystal display 15 with the displacement of the current position of the vehicle. Move the location on the map. Specifically, the vehicle position mark is moved so that the vehicle position mark is located at a position on the map corresponding to the current position of the current vehicle. When the position of the vehicle position mark on the screen is fixed, the surrounding map image relatively scrolls. Then, the process returns to S24.

  On the other hand, in S26, the CPU 41 starts moving the virtual position mark indicating the virtual position of the vehicle together with the own vehicle position mark indicating the current position of the vehicle. Specifically, when the virtual position of the vehicle departs from the movement start point set in S19 and travels along the history route to the destination side in the same traveling manner as in the past at the timing satisfying the condition of S24. The virtual position mark is defined and moved so that the virtual position mark is located at a position on the map corresponding to the current virtual position. Note that the travel history stores the history of the detection points (position coordinates) of the current position of the vehicle with the lapse of time until the vehicle arrives at the destination. It is possible to specify the position with the passage of time. As a result, it is possible to reproduce the travel mode (stop at an intersection, acceleration / deceleration associated with the road shape, vehicle speed, etc.) when the vehicle has traveled on the history route in the past by the movement of the virtual position mark.

  Here, FIG. 9 is a diagram showing an example of a travel guidance screen 75 displayed on the liquid crystal display 15 after the vehicle starts moving. On the travel guidance screen 75, a virtual position mark 77 indicating a virtual position of a vehicle moving on the history route 72 is displayed separately from the own vehicle position mark 74. Note that, since the map image 71 is to display the area around the own vehicle position, the virtual position mark 77 may not be displayed when the virtual position is far from the current position of the vehicle. Then, when referring to the travel guidance screen 75, the user can grasp the traveling mode of the past vehicle heading for the same destination by the virtual position mark 77.

  When the virtual position of the vehicle is specified based on the travel history, the history of the position coordinates of the vehicle that has moved along the history route 72 from the departure point to the movement start point set in S19 is described below. Exclude and move the virtual position of the vehicle for the remaining history. That is, the virtual position moves from the movement start point to the destination along the history route 72.

  Thereafter, in S27, the CPU 41 determines whether or not the vehicle has arrived at the destination. Specifically, when it is determined that the current position of the vehicle is within a predetermined distance (for example, within 50 m) from the destination, it is determined that the vehicle has arrived at the destination.

  When it is determined that the vehicle has arrived at the destination (S27: YES), the travel guidance processing program ends. On the other hand, when it is determined that the vehicle has not arrived at the destination (S27: NO), the process returns to S26, and guidance of the own vehicle position mark and the virtual position mark is continuously performed.

  Next, a sub-process of the movement start point setting process executed in S19 will be described with reference to FIG. FIG. 10 is a flowchart of a sub-processing program of the movement start point setting processing.

  First, in S31, the CPU 41 compares the guide route set in S17 with the history route, and determines whether at least a part of the guide route and the history route overlap (except when only the destination overlaps). judge.

  When it is determined that the guidance route and the history route overlap at least partially except for the destination (S31: YES), the process proceeds to S32. On the other hand, when it is determined that the guidance route and the history route do not overlap each other except at the destination (S31: NO), the process proceeds to S33.

  In S32, the CPU 41 moves the virtual start position to the point closest to the departure point among the points on the history route that overlap with the guidance route (that is, overlap with the vehicle moving on the guidance route). Set as For example, when the guide route 76 and the history route 72 overlap as shown in FIG. 11, the point X is set as the movement start point. The point X is a point corresponding to the position of the vehicle (user) moving on the guide route 76.

  In step S32, the CPU 41 determines a point on the history route that is within a predetermined distance (for example, 300 m) from the guide route (that is, within a predetermined distance from the vehicle traveling on the guide route), and is a point closest to the departure point. May be set as the movement start point. For example, when the guide route 76 and the history route 72 overlap as shown in FIG. 12, the point X may be set as the movement start point, but the distance L from the guide route 76 is a predetermined distance (for example, 300 m). The point Y, which is the point closest to the departure point within the parentheses, may be set as the movement start point. Note that if the point Y is the movement start point, the virtual position cannot be started to move from the same position as the current position of the vehicle. However, the virtual position and the current position of the vehicle can be compared with the case where the point X is the movement start point. Can be extended. Then, the process proceeds to S34.

  On the other hand, in S33, the CPU 41 determines the most departure point side point among the points on the history route and within a predetermined distance (for example, 300 m) from the guidance route (that is, within a predetermined distance from the vehicle traveling on the guidance route). Set as the movement start point. For example, when the guide route 76 and the history route 72 do not overlap except for the destination as shown in FIG. 13, the distance L from the guide route 76 is within a predetermined distance (for example, 300 m) and is closest to the departure point. A point Y, which is a point, is set as a movement start point. The point Y is a point corresponding to the position of the vehicle (user) moving on the guide route 76. Then, the process proceeds to S34.

  In S34, the CPU 41 determines whether or not the movement start point set in S32 or S33 is on the guide route.

  When it is determined that the movement start point is on the guide route (S34: YES), the process proceeds to S35. On the other hand, when it is determined that the movement start point is not on the guide route (S34: NO), the process proceeds to S36.

  In S35, the CPU 41 sets the timing at which the vehicle reaches the movement start point on the guide route as the timing to start moving the virtual position. For example, as shown in FIG. 11, when the point X where the guide route 76 and the history route 72 overlap is set as the movement start point, the timing at which the vehicle arrives at the point X starts the movement of the virtual position. Set the timing to perform. As a result, after that, when the vehicle travels along the guide route and reaches the point X, the virtual position starts to move simultaneously from the same point X (S26). Thereafter, the process proceeds to S20.

  On the other hand, in S36, the CPU 41 sets the timing at which the vehicle arrives at the point closest to the movement start point on the guide route as the timing to start moving the virtual position. For example, as shown in FIGS. 12 and 13, when the point Y that is the history route 72 and approaches the guide route 76 within a predetermined distance is set as the movement start point, the vehicle comes closest to the point Y. The timing at which point Z is reached is set as the timing at which the movement of the virtual position is started. As a result, after that, when the vehicle travels along the guide route and reaches the point Z, the virtual position starts moving from the point Y (S26). Thereafter, the process proceeds to S20.

  As described above in detail, in the navigation device 1 according to the first embodiment and the computer program executed by the navigation device 1, the traveling is performed by associating the setting history of the destination of the user with the traveling history of the vehicle with respect to the set destination. On the other hand, when the vehicle travels according to the guidance route, the traveling history of traveling to the same destination as the guidance route is acquired from the traveling history DB 32 (S18), and the acquired traveling is stored in the history DB 32 (S6). A point on the history route specified by the history and corresponding to the position of the vehicle traveling on the guide route is set as a movement start point (S19), and the vehicle moves from the movement start point to the destination along the history route. Since the virtual position of the traveling vehicle is displayed on the liquid crystal display 15 (S26), the traveling history of traveling on the same route as the planned traveling route of the vehicle Even if it does not exist, it is possible to guide as compared with the same easy suitable manner comparing the travel history of the vehicle towards the destination. Further, since the movement start point at which the movement of the virtual position is started is corrected to a position corresponding to the position of the vehicle traveling on the planned movement route, even if the departure place of the planned movement route and the departure point of the history route are different, It is possible to easily compare the planned route and the history route. Then, the user can select a more appropriate route to the destination by referring to the guided comparison result. For example, even if the facility that is the departure place of the planned travel route and the history route is the same, if the area of the facility is large (for example, in the case of a large parking lot), the departure places are separated from each other. Although it becomes difficult to compare the planned route and the history route, the comparison is facilitated by correcting the movement start point of the virtual position. Further, even when the user starts moving from a point in the middle of the history route, the position of the vehicle and the virtual position can be matched, which is very effective.

[Second embodiment]
Next, a navigation device according to a second embodiment will be described with reference to FIGS. In the following description, the same reference numerals as those of the configuration of the navigation device 1 according to the first embodiment in FIGS. 1 to 13 indicate the same or corresponding parts as those of the navigation device 1 and the like according to the first embodiment. It is.

The schematic configuration of the navigation device according to the second embodiment is substantially the same as the configuration of the navigation device 1 according to the first embodiment. Further, various control processes are substantially the same as the navigation device 1 according to the first embodiment.
However, in the first embodiment, the navigation device 1 determines that the point closest to the departure point on the history route and overlaps with the guide route or within a predetermined distance from the guide route is the movement start point of the virtual position. In contrast to the setting (S32, S33), the navigation device according to the second embodiment starts moving the virtual position to a point on the history route that is separated from the destination by the route length of the guide route along the history route. It differs from the navigation device 1 according to the first embodiment in that it is a point.

  Hereinafter, the sub-process of the movement start point setting process of S19 in the travel guidance process program executed in the navigation device according to the second embodiment will be described with reference to FIG. FIG. 14 is a flowchart of a sub-processing program of a movement start point setting process according to the second embodiment.

  First, in S41, the CPU 41 acquires a route length T from the departure point (that is, the point where the vehicle starts running) of the guide route set in S17 to the destination.

  Next, in S42, the CPU 41 sets a point on the history route that is separated from the destination by the route length T along the history route as a movement start point at which the movement of the virtual position is started. For example, when the guide route 76 and the history route 72 exist as shown in FIG. 15, a point Q separated from the destination by the route length T to the departure point side is set as the movement start point. The point Q is a point corresponding to the position of the vehicle (user) moving on the guide route 76.

  Here, assuming that the point Q is a movement start point, the guide route 76 and the history route 72 are routes having greatly different route lengths and shapes as shown in FIG. In the case where the other is a route traveling on a general road, for example), the guide route 76 and the history route 72 can be compared.

  That is, as shown in FIG. 15, when the guide route 76 and the history route 72 have the same departure place but have different route lengths and shapes, if the virtual position is to be moved from the departure place, The history route 72 and the virtual position mark 77 indicating the virtual position (see FIG. 9) are displayed on the screen at the start of the guidance, but are hardly displayed on the screen until the destination is reached. A guide effective for the user cannot be provided. On the other hand, assuming that the movement start point of the virtual position is not the departure point but the point Q separated from the destination by the path length T toward the departure point, it is assumed that the history path 72 and the virtual position mark 77 are hardly displayed on the screen. Also, the user can know whether or not the history route 72 is a superior route compared to the guide route 76. Specifically, if the virtual position arrives at the destination before the vehicle, it can be understood that the history route 72 is an excellent route that can travel the same distance faster than the guide route 76. On the other hand, if the vehicle arrives at the destination before the virtual position, it can be understood that the guide route 76 is an excellent route that can travel the same distance faster than the history route 72.

  Thereafter, in S43, the CPU 41 sets the timing at which the vehicle starts moving as the timing at which the movement of the virtual position is started. As a result, as shown in FIG. 15, when the point Q on the history route 72 is set as the movement start point, the vehicle starts moving from the departure point, and the virtual position is not the departure point but the point Q. The movement is started (S26).

  As described above in detail, the navigation device according to the second embodiment and the computer program executed by the navigation device associate the travel history of the vehicle with the travel history of the vehicle with respect to the set destination by associating the travel history DB32 On the other hand, when the vehicle travels according to the guide route, the travel history of traveling to the same destination as the guide route is acquired from the travel history DB 32, and the history is specified on the history route specified by the acquired travel history. In particular, a point that is separated from the destination by the route length T of the guide route along the history route is set as the movement start point (S42), and the vehicle moves from the movement start point to the destination along the history route. Is displayed on the liquid crystal display 15, so that there is no traveling history of traveling on a route close to the planned route of the vehicle. Even, it is possible to guide as compared with the same easy suitable manner comparing the travel history of the vehicle towards the destination. Then, the user can select a more appropriate route to the destination by referring to the guided comparison result.

It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.
For example, in the first and second embodiments, the history of the detection points (position coordinates) of the destination and the current position of the vehicle is stored as the traveling history of the vehicle, but the departure point and the waypoint are also stored. It is good also as a structure which performs. Further, a configuration may be employed in which a line segment (travel locus) connecting the detection points is stored instead of the detection point (position coordinates) of the current position of the vehicle.

  Further, in the first embodiment and the second embodiment, the traveling history that is the same destination as the guidance route is set as the guidance target, but the traveling history in which both the destination and the departure place match may be set as the guidance target. In addition, when a stopover is set, a traveling history that matches the stopover may be set as the guidance target. Further, not only the traveling history of the own vehicle but also the traveling history of another vehicle may be set as the guidance target. In such a case, the driving history of another vehicle is acquired by communication with an external server or inter-vehicle communication.

  In the first and second embodiments, the destination is selected from a list of past destinations displayed on the destination list screen 61 (FIG. 5), and is set as the destination of the navigation device 1. However, the destination may be searched for from the genre or the name and set.

  Further, in the first embodiment and the second embodiment, when the guidance route is set in the navigation device 1 and the traveling guidance based on the guidance route is performed, the virtual position of the vehicle is displayed. It is possible to display the virtual position of the vehicle even if the route to be moved in the future can be specified, even if the guidance route is not set or the traveling guidance based on the guidance route is not performed.

  Further, the present invention can be applied to a device having a function of guiding a user's movement in addition to a navigation device. For example, the present invention can be applied to a mobile phone, a smartphone, a tablet terminal, a personal computer, and the like (hereinafter, referred to as a mobile terminal and the like). Further, the present invention can be applied to a system including a server and a portable terminal. In that case, each step of the above-described travel history storage processing program (FIG. 3) and the travel guidance processing program (FIG. 4) may be configured to be performed by any of the server and the portable terminal. When the present invention is applied to a mobile terminal or the like, a configuration is adopted in which a travel history of a mobile body other than a vehicle, for example, a user of a mobile terminal or a motorcycle or the like is stored in the travel history DB 32 and guided. You may.

  Further, although the embodiment in which the movement guide device according to the present invention is embodied has been described above, the movement guide device can also have the following configuration, and in that case, the following effects can be obtained.

Therefore, when there is no movement history that has moved along the same route as the planned route. However, it is possible to guide the user's movement histories toward the same destination as a comparison target in an appropriate mode that is easy to compare. In addition, since the movement start point at which the movement of the virtual position is started is corrected to a position corresponding to the position of the user who moves on the planned movement route, even if the departure place of the planned movement route and the history route is different, It is possible to easily compare the planned route and the history route. Then, the user can select a more appropriate route to the destination by referring to the guided comparison result. For example, even if the facility that is the departure place of the planned travel route and the history route is the same, if the area of the facility is large (for example, in the case of a large parking lot), the departure places are separated from each other. Although it becomes difficult to compare the planned route and the history route, the comparison is facilitated by correcting the movement start point of the virtual position. Further, even when the user starts moving from a point in the middle of the history route, the position of the vehicle and the virtual position can be matched, which is very effective.

Since the movement can be started at the same time, the planned movement path and the history path can be easily compared based on the movement of the virtual position.

The sixth configuration is as follows.
A route length acquisition unit (13) for acquiring a route length from a point at which the user starts to move to the destination on the planned movement route (76); and the virtual position display unit includes the history route (72). A point that is above and is separated from the destination by the route length along the history route is defined as the movement start point.
According to the movement guidance device having the above configuration, even when the planned movement route and the history route are routes having greatly different path lengths and shapes, the movement start position of the virtual position and the movement distance to the destination are determined by the user. Is corrected so as to be the same distance as the planned travel route, it is possible to compare the planned travel route and the history route using the order of arrival at the destination.

The seventh configuration is as follows.
