Description

  The present invention relates to a route registration device and a route registration method for registering a travel route on which a vehicle travels on a daily basis.

  Conventionally, as this type of route registration device, for example, an in-vehicle navigation device described in Patent Document 1 has been proposed. In this in-vehicle navigation device, a travel route on which the host vehicle travels is registered as a travel history.

  The travel history registered in this way is used in various vehicle controls. For example, when the vehicle travels on a travel route registered as a travel history, the fuel supply mode can be appropriately controlled so that fuel efficiency is improved.

JP 2008-249536 A

  By the way, some navigation devices that can register the travel history of the host vehicle acquire a travel route every time the host vehicle travels. In such a navigation device, every time the host vehicle arrives at the destination, the occupant is notified whether or not to register the acquired travel route. When the occupant permits registration, the acquired travel route is registered in the memory. That is, in the memory of the navigation device, there is a possibility that not only a travel route on which the host vehicle travels on a daily basis (also referred to as “daily route”) but also a travel route on which the vehicle travels only once is registered. Therefore, since a large number of travel routes may be registered in the memory, it becomes necessary to mount a large-capacity memory in the navigation device. Therefore, there has been a demand for a technique for limiting the opportunity for a travel route other than the daily route to be registered in the memory.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a route registration device and a route registration method capable of suppressing registration of a travel route other than a travel route that travels on a daily basis. It is to provide.

In order to achieve the above object, the route registration apparatus of the present invention comprises a data storage means for storing management data including a departure place and an arrival place, and the number of times the vehicle has traveled from the departure place to the arrival place; a position acquisition means for acquiring a departure and arrival locations, at the time of but traveled, when management data including has been the departure and arrival locations acquired by the position acquiring means is not yet stored in the data storage device, the starting Data registration means for registering new management data including the place and the arrival place in the data storage means, and management data including the departure place and the arrival place acquired by the position acquisition means are stored in the data storage means. The update means for updating the number of times of travel included in the management data, the starting point at the start of the current vehicle travel, and the number of times of travel greater than a predetermined value A route that starts acquisition of the travel route of the vehicle when the management data is already stored in the data storage means, and ends the acquisition of the travel route when the vehicle arrives at the arrival location included in the management data. The gist of the invention is to include an acquisition unit and a route storage unit that stores the travel route acquired by the route acquisition unit.

  According to the above configuration, when the vehicle travels, the departure place and the arrival place of the vehicle are acquired. If the management data including the acquired departure place and arrival place is not stored in the data storage means, the management data is registered in the data storage means. On the other hand, when the management data including the acquired departure place and arrival place is stored in the data storage means, the number of travels included in the management data is updated. In the case where management data (also referred to as “current management data”) having the starting point and the number of times of travel exceeding the specified value is stored in the data storage means, the travel route of the vehicle is acquired. Is started. In this state, when the vehicle arrives at the arrival location included in the current management data, the acquisition of the travel route of the vehicle is terminated and the travel route is stored in the route storage means.

  Here, when the “specified value” is a determination value for determining whether or not the travel route on which the vehicle will travel is a route on which the vehicle travels on a daily basis (also referred to as “daily route”), When it is determined that there is a possibility that the vehicle does not travel on the daily route, the travel route is not acquired. That is, even an opportunity for registering the travel route is not given. Therefore, it is possible to suppress registration of travel routes other than the daily route, and consequently to suppress an increase in the storage amount stored in the route storage means.

  The route registration apparatus according to the present invention includes an information acquisition unit that acquires determination information used for determining whether to forcibly end acquisition of a travel route by the route acquisition unit, and a determination acquired by the information acquisition unit. Determination means for determining whether or not a forced termination condition is satisfied based on the information, and the route acquisition means, when the determination means determines that the forced termination condition is satisfied, And the travel route acquired before the forced termination condition is satisfied is not stored in the route storage means.

  Even if the acquisition start condition of the travel route of the vehicle is satisfied and the acquisition of the travel route is started, the vehicle is actually at a point different from the arrival place included in the read management data (current management data). May be heading. Moreover, even if the vehicle is heading to the arrival place included in the current management data, the vehicle may travel along a travel route different from the daily route. In such a case, it is preferable to forcibly end the acquisition of the travel route and restrict the storage of the travel route in the route storage means. Therefore, in the present invention, when it is determined that the vehicle is not traveling on the daily route based on the obtained determination information, the acquisition of the travel route is forcibly terminated, and the travel route is stored in the route storage means. Not remembered. Therefore, the control load of the route registration device associated with the acquisition of the travel route can be reduced by the amount that the acquisition of the travel route is forcibly terminated when it is determined that the vehicle is not traveling on the daily route.

  In the route registration device of the present invention, the information acquisition unit acquires the current time as the determination information, and the determination unit acquires the current time acquired by the information acquisition unit by the position acquisition unit. If the determination time set based on the management data including the departure place and the arrival place is exceeded, it is determined that the forced termination condition is satisfied.

  According to the above configuration, when the vehicle travel route acquisition start condition is satisfied and the travel route acquisition is started, the current time is acquired as the determination information. When the acquired current time exceeds the determination time set based on the read management data (current management data), it is determined that the forced termination condition is satisfied, and the travel route is It is not stored in the route storage means. Therefore, the control load of the route registration device associated with the acquisition of the travel route can be reduced by the amount that the acquisition of the travel route is forcibly terminated when it is determined that the vehicle is not traveling on the daily route.

  In the route registration device of the present invention, the management data further includes a departure time when the vehicle departs from the departure place, and the position acquisition means includes the departure place and the arrival place when the vehicle travels, The departure time when the vehicle departed from the departure place is acquired, and the data registration means stores management data including the departure place, arrival place and departure time acquired by the position acquisition means in the data storage means. In some cases, the management data is registered in the data storage means, and the update means stores management data including the departure place, arrival place, and departure time acquired by the position acquisition means in the data storage means. In some cases, the number of times of travel included in the management data is updated, and the route acquisition means is configured to determine whether the current vehicle travels at a departure point, a departure time, and a travel exceeding the specified value If the management data including the number is already stored in the data storage means, it starts acquiring travel route of the vehicle.

  When a vehicle travels on a daily route, the departure time of the vehicle is often the same as the departure time when the vehicle traveled on a daily route by the previous time. Therefore, according to the present invention, when management data (current management data) including the departure point, departure time, and the number of times of travel exceeding the specified value is stored in the data storage unit, the vehicle travels. Route acquisition starts. On the other hand, when there is a possibility that the current travel route of the vehicle is a travel route other than the daily route, the current travel route of the vehicle is not acquired. Therefore, acquisition of travel routes other than the daily route can be suppressed.

The present invention relates to a route registration method for acquiring a travel route traveled by a vehicle and storing the travel route in a route storage means of a control device. The control device includes a departure place, an arrival place, and the departure place. A data storage means for storing management data including the number of times the vehicle has traveled to the arrival place is provided, a position acquisition step for acquiring a departure place and an arrival place when the vehicle has traveled, and the position acquisition step A data registration step for registering new management data including the departure place and the arrival place in the data storage means when the management data including the departure place and the arrival place acquired in (2) is not stored in the data storage means; When the management data including the departure place and the arrival place acquired in the position acquisition step has been stored in the data storage means, the number of times of travel included in the management data An update step to be updated, and when the management data including the departure point at the start of the current vehicle travel and the number of times of travel exceeding a preset specified value have been stored in the data storage means, the travel route of the vehicle is acquired. A route acquisition step for starting the acquisition of the travel route when the vehicle arrives at the arrival location included in the management data, and the travel route for which the acquisition in the route acquisition step is completed in the route storage means And a path storing step for storing.

  According to the said structure, the effect | action and effect equivalent to the said path | route registration apparatus can be acquired.

Is remembered. The facility data storage unit 242 stores various facilities such as restaurants, gas stations, hospitals, parking lots, and facility data such as addresses and telephone numbers of the various facilities.

  The history information storage unit 25 is a storage unit for storing a travel route on which the host vehicle travels on a daily basis as a daily route (daily route), and includes a nonvolatile memory such as an EEPROM. The history information storage unit 25 includes a table storage area 250 as data storage means for storing the daily route prediction management table shown in FIG. 2, a route storage area 251 as route storage means for storing daily routes, An IG on / off storage area 252 for storing a departure place and an arrival place when the host vehicle traveled last time is formed.

Next, the daily route prediction management table will be described with reference to FIG.
In this daily route prediction management table, management data necessary for determining whether or not the vehicle travels this time is acquired. As shown in FIG. 2, the daily route prediction management table can manage a maximum of M pieces of management data (M is an integer of 2 or more, for example, 10 pieces). The management data includes departure place relation information for specifying the departure place PS and departure time TS of the host vehicle, arrival place relation information for specifying the arrival place PG and arrival time TG, the number of times of travel N, and the presence / absence of route registration. The data structure is included. The number of times of travel N is the number of times that the vehicle departed from the departure place PS indicated by the departure place relation information at around the departure time TS, and the own vehicle arrived at the arrival place PG indicated by the arrival place relation information at around the arrival time TG. is there. The presence / absence of route registration refers to whether or not the travel route from the departure point PS indicated by the departure point relationship information to the arrival point PG indicated by the arrival point relationship information is stored (registered) in the route storage area 251 as an everyday route. Is to judge.

Next, each management data shown in FIG. 2 will be described.
In the management data with the candidate number P being “1”, the departure time TS is set to “8:00” and the departure place PS is set to “home”. In addition, the arrival time TG is set to “9:00”, and the arrival place PG is set to “XX town”. Further, the number N of times of travel is set to “20 times”, and whether or not there is route registration is set. In the management data with the candidate number P being “2”, the departure time TS is set to “7:30” and the departure place PS is set to “home”. In addition, the arrival time TG is set to “8:30” and the arrival place PG is set to “◯ △ town”. Furthermore, the number N of times of travel is set to “10 times”, and whether or not there is route registration is set.

  In the management data with the candidate number P being “3”, the departure time TS is set to “8:30” and the departure place PS is set to “◯ △ town”. In addition, the arrival time TG is set to “10:00”, and the arrival place PG is set to “Ox Town”. Further, the number N of times of travel is set to “10 times”, and whether or not there is route registration is set. In the management data with the candidate number P being “4”, the departure time TS is set to “18:30”, and the departure place PS is set to “Ox Town”. Also, the arrival time TG is set to “19:30” and the arrival place PG is set to “home”. Further, the number N of times of travel is set to “30 times”, and whether or not there is route registration is set.

  In the management data with the candidate number P being “5”, the departure time TS is set to “12:10”, and the departure place PS is set to “□ Δ town”. In addition, the arrival time TG is set to “18:00” and the arrival place PG is set to “XX town”. Further, the number N of times of travel is set to “1”, and the presence / absence of route registration is set to be absent. The management data with the candidate number P being “10” is not set.

  The navigation device 11 of the present embodiment has a function of registering a travel route on which the host vehicle travels on a daily basis as a daily route. In order to register the daily route, the travel route from the departure point of the vehicle (that is, the point where an ignition switch (not shown) is turned on) to the arrival point of the vehicle (that is, the point where the ignition switch is turned off) is Need to get. On the other hand, there is no need to register a travel route that does not travel on a daily basis. In the present embodiment, the use of the daily route prediction management table determines whether or not the travel route can be acquired during the current vehicle travel.

  Therefore, various control processing routines executed by the control unit 22 of the present embodiment will be described with reference to the flowcharts shown in FIGS. 3, 4, and 5. In addition, the flowchart shown in FIG. 3 is a flowchart for demonstrating the IG on / off information acquisition process routine for acquiring the departure place and arrival place at the time of driving | running | working of the own vehicle. Further, the flowcharts shown in FIGS. 4 and 5 are flowcharts for explaining a daily route registration processing routine for acquiring a travel route when the host vehicle is traveling this time.

First, the IG on / off information acquisition processing routine will be described with reference to FIG.
Now, the IG on / off information acquisition processing routine is executed at predetermined intervals (for example, every 0.1 second) while the ignition switch (not shown) of the host vehicle is on. In the IG on / off information acquisition processing routine, the control unit 22 determines whether or not the IG flag FLG is off (step S10). The IG flag FLG is “off” immediately after an ignition switch (not shown) of the host vehicle is turned on. That is, in step S10, it is determined whether or not it is immediately after an ignition switch (not shown) is turned on.

  When the IG flag FLG is on (step S10: NO), the control unit 22 shifts the process to step S13, which will be described later, because it is not immediately after the ignition switch (not shown) is turned on. On the other hand, when the IG flag FLG is off (step S10: YES), the control unit 22 acquires the current position and the current time of the host vehicle as the departure place and the departure time (step S11). Subsequently, the control unit 22 sets the IG flag FLG to ON (step S12), and proceeds to the next step S13.

  In step S13, the control unit 22 determines whether or not the IG is turned off, that is, whether or not an ignition switch (not shown) is turned off. When the IG is not turned off (step S13: NO), the control unit 22 determines that the host vehicle is traveling and ends the IG on / off information acquisition processing routine once. On the other hand, when the IG is turned off (step S13: YES), the control unit 22 acquires the current position and the current time of the host vehicle as the arrival place and the arrival time (step S14). Subsequently, the control unit 22 determines the departure place relation information for specifying the departure place and the departure time acquired in step S11 and the arrival place relation information for specifying the arrival place and arrival time acquired in step S14. A storage process to be stored in the on / off storage area 252 is performed (step S15), and the IG on / off information acquisition process routine is terminated.

Next, the daily route registration processing routine executed by the control unit 22 of the present embodiment will be described with reference to the flowcharts shown in FIGS.
The routine route registration process routine is started at the timing when an ignition switch (not shown) of the host vehicle is turned on. Then, in the daily route registration processing routine, the control unit 22 acquires the departure point relationship information at the previous travel of the host vehicle from the IG on / off storage area 252 (step S20), and the arrival point relationship information at the previous travel of the host vehicle. Is acquired from the IG on / off storage area 252 (step S21). That is, in each step S20, S21, the departure place and departure time at the previous travel indicated by the departure place relation information and the arrival place and arrival time at the previous travel indicated by the arrival place relation information are acquired. Therefore, in the present embodiment, the control unit 22 functions as a position acquisition unit that acquires a departure place and an arrival place when the vehicle travels. Moreover, a position acquisition step is comprised by step S20, S21.

Subsequently, the control unit 22 determines whether or not the management data including the acquired departure place, departure time, arrival place, and arrival time is in the daily route prediction management table (see FIG. 2) (step S22). For example, in step S22, it is determined whether or not management data that satisfies all of the following four conditions is in the daily route prediction management table.
(First condition) Management data including a departure point PS located in a region whose radius centered on the departure point acquired in step S20 is a reference value (for example, 100 m).
(Second condition) Management data including an arrival place PG having a radius centered on the arrival place acquired in step S21 and located within a reference value area.
(Third condition) Management data including a departure time TS that is between a time obtained by subtracting a reference time (for example, 30 minutes) from the departure time acquired in step S20 and a time obtained by adding the reference time from the departure time. There is.
(Fourth condition) Management data including arrival time TG between the time obtained by subtracting the reference time from the arrival time acquired in step S21 and the time obtained by adding the reference time from the arrival time.

  When there is management data that satisfies all the conditions, the control unit 22 determines that the management data including the departure place, departure time, arrival place, and arrival time acquired in steps S20 and S21 is in the daily route prediction management table. (Step S22: YES). Then, the control unit 22 increments the number N of times of travel included in the corresponding management data (also referred to as “previous management data”) by “1” (step S23). Therefore, in this embodiment, when the control unit 22 stores the management data (previous management data) including the acquired departure place and arrival place in the table storage area 250 (predictive management table), the management data It also functions as an updating means for updating the number N of times of travel included in the data. Step S23 corresponds to an update step. Then, the control part 22 transfers the process to step S27 mentioned later.

  On the other hand, when there is no management data that satisfies all the conditions, the control unit 22 does not have the previous management data including the departure place, departure time, arrival place, and arrival time acquired in steps S20 and S21 in the daily route prediction management table. (Step S22: NO). Subsequently, the control unit 22 determines whether or not there is a space for storing new management data (previous management data) in the daily route prediction management table (step S24). If it is determined that there is a vacancy (step S24: YES), the control unit 22 proceeds to step S26 described later. On the other hand, if it is determined that there is no free space (step S24: NO), the control unit 22 discards the management data that minimizes the number of times of travel N among all the management data in the daily route prediction management table (step S25). ). Then, the control part 22 transfers the process to following step S26.

  In step S26, the control unit 22 performs a registration process for registering (storing) the previous management data including the departure place, departure time, arrival place, and arrival time acquired in steps S20 and S21 in the daily route prediction management table. At this time, the running count N included in the previously registered management data is set to “1”. Therefore, in this embodiment, when the previous management data including the acquired departure place and arrival place is not stored in the table storage area 250 (prediction management table), the control unit 22 stores the previous management data. It also functions as data registration means for registering in the table storage area 250 (prediction management table). Step S26 corresponds to a data registration step. And the control part 22 transfers the process to following step S27.

In step S27, the control unit 22 acquires the current position and the current time of the host vehicle as the departure place and the departure time at the start of the current travel. Subsequently, the control unit 22 determines whether or not the management data including the acquired departure time and departure time at the start of the current traveling is in the prediction management table (step S28). For example, in step S28, it is determined whether or not management data that satisfies all of the following two conditions exists in the daily route prediction management table. In the following description, “management data including the departure place and departure time at the start of the current travel” is referred to as “current management data”.
(Fifth condition) Management data including a departure point PS whose radius centered on the departure point at the start of traveling this time is located within a reference value region.
(Sixth condition) Management data including a departure time TS that is between a time obtained by subtracting a reference time (for example, 30 minutes) from the departure time at the start of the current traveling and a time obtained by adding the reference time from the departure time. Be.

  If the current management data is not in the prediction management table (step S28: NO), the control unit 22 ends the routine route registration processing routine. On the other hand, when the current management data is in the prediction management table (step S28: YES), the control unit 22 determines whether or not the daily route from the departure point to the arrival point included in the present management data has been registered. Determination is made (step S29). When the daily route is not registered (step S29: NO), the control unit 22 proceeds to step S31 described later. On the other hand, if the daily route has been registered (step S29: YES), the candidate number P (for example, 1) of the current management data is acquired as the registered number F (step S30), and then the processing is performed in the next step. The process proceeds to S31.

  In step S31, the control unit 22 determines whether or not the number N of times of travel included in the current management data is equal to or greater than a preset specified value Nth (for example, 10). This specified value Nth is a determination value for determining whether or not the travel route on which the host vehicle will travel is an everyday route. If the number N of travels is less than the specified value Nth (step S31: NO), the control unit 22 ends the routine route registration process routine. On the other hand, if the number of times of travel N is equal to or greater than the specified value Nth (step S31: YES), the control unit 22 determines that the acquisition start condition for the travel route of the host vehicle is satisfied, and A travel route is acquired (step S32). At this time, the control unit 22 stores the travel route in a predetermined storage area of the RAM 222.

  Then, the control unit 22 determines whether or not the own vehicle has arrived at the arrival place PG included in the current management data (step S33). For example, when the current management data is management data with the candidate number P being “1”, the control unit 22 determines whether or not it has arrived at “Ox Town”. Specifically, when it is established that the current position of the host vehicle is located within the reference value area with the radius centered on the arrival point PG included in the current management data, the control unit 22 It determines with having arrived at the ground PG.

  When the host vehicle has arrived at the arrival place PG (step S33: YES), the control unit 22 ends the acquisition of the travel route, and the process proceeds to step S36 described later. Therefore, in the present embodiment, the control unit 22 also functions as a route acquisition unit. In addition, a route acquisition step is configured by steps S32 and S33.

  On the other hand, when the host vehicle has not arrived at the arrival place PG (step S33: NO), the control unit 22 acquires forced termination determination information used to determine whether or not to forcibly end the acquisition of the travel route. (Step S34). And the control part 22 determines whether the forced termination condition was satisfied based on the acquired forced termination determination information (step S35). When the forced termination condition is satisfied (step S35: YES), the control unit 22 terminates the daily route registration processing routine without storing the travel route acquired so far in the route storage area 251. On the other hand, when the forced termination condition is not satisfied (step S35: NO), the control unit 22 proceeds to step S32 described above. That is, the control unit 22 continues to acquire the travel route. Therefore, in the present embodiment, the control unit 22 also functions as an information acquisition unit and a determination unit.

  In the present embodiment, the current time (current time) is acquired as the forced termination determination information. The forced termination condition is set to a condition that the current time has exceeded the determination time set based on the current management data. For example, the determination time is a time obtained by adding the reference time to the arrival time TG included in the current management data. That is, when the management data of this time is management data with the candidate number P being “1”, the determination time is a time obtained by adding a reference time (for example, 30 minutes) to “9:00” (for example, 9:00) 30 minutes). Therefore, in step S35, it is determined whether or not the current time has exceeded “9:30”. If the current time does not exceed “9:30”, the acquisition of the travel route is continued. On the other hand, if the current time exceeds “9:30”, the current travel route is not an everyday route because the host vehicle cannot arrive at the arrival place PG by “9:30” as the determination time. It is determined that the travel route is forcibly terminated.

  In step S36, the control unit 22 determines whether the registered number F has not been acquired. When the registered number F has not been acquired (step S36: YES), the control unit 22 determines whether or not to register the travel route acquired this time (hereinafter also referred to as “current travel route”) as the daily route. A registration confirmation process is performed to prompt the passenger of the vehicle to make such a determination (step S37). At this time, the control unit 22 causes the display 13 to display a message requesting the passenger to permit registration of the current travel route. Then, the control part 22 transfers the process to step S40 mentioned later.

  On the other hand, when the registered number F has been acquired (step S36: NO), the control unit 22 reads the daily route corresponding to the registered number F from the route storage area 251. Then, the control unit 22 determines whether or not the current travel route matches the read daily route (step S38). Therefore, in this embodiment, when the acquisition of the travel route is completed, the control unit 22 uses a route different from the travel route (daily route) stored in the route storage area 251 when the travel route (current travel route) is stored. It also functions as route determination means for determining whether or not there is.

  When the current travel route matches the read daily route (step S38: NO), the control unit 22 determines that it is not necessary to newly store (register) the current travel route, and the daily route registration processing routine Exit. On the other hand, if the current travel route does not match the read daily route (step S38: YES), the control unit 22 permits the current travel route to be stored (registered) in the route storage area 251 as the daily route. . Therefore, in the present embodiment, when the control unit 22 determines that the current travel route is different from the travel route (daily route) stored in the route storage area 251, the acquired current travel route. It also functions as a permission means for permitting storage in the root storage area 251.

  And the control part 22 performs the route replacement confirmation process which confirms with the passenger | crew of the own vehicle whether the registered daily route may be changed into this driving | running route (step S39). At this time, the control unit 22 causes the display 13 to display a message to the occupant asking for permission to replace the daily route. Then, the control part 22 transfers the process to following step S40.

  In step S40, the control unit 22 determines whether or not the occupant is permitted to store the current travel route by an input operation by the occupant of the host vehicle. If storage of the current travel route is not permitted by the input operation by the occupant (step S40: NO), the control unit 22 does not store the current travel route in the route storage area 251 and does not store the current travel route. Exit. On the other hand, when storage of the current travel route is permitted by an input operation by the occupant (step S40: YES), the control unit 22 stores the current travel route as the daily route in the route storage area 251 (step S41). . At this time, the control unit 22 stores the current travel route in the route storage area 251 in association with the candidate number P attached to the current management data. Therefore, in this embodiment, step S41 corresponds to a route storage step. Thereafter, the control unit 22 ends the routine route registration processing routine.

  Next, the operation when the travel route is acquired will be described. Here, it is assumed that “home” departs at “8:00” and the vehicle arrives at “XX town” at “9:00”.

  When the host vehicle departs from the home, the navigation device 11 reads management data with the candidate number “1” from the daily route prediction management table as current management data including the current departure place PS and departure time TS. (See FIG. 2). Then, acquisition of the current travel route is started.

  Then, when the current position of the host vehicle is located in an area where the radius centered on the arrival point PG included in the current management data is the radius of the reference value (for example, 100 m), the travel route is acquired. Is terminated. At this time, the driver may be decelerating the host vehicle because the host vehicle is located near the destination PG, which is the destination.

  Then, a message for confirming whether or not to register the current travel route as the daily route is displayed on the display 13 of the navigation device 11. This message is often displayed on the display 13 during deceleration of the host vehicle (that is, before stopping). And if the passenger | crew of the own vehicle inputs that registration is permitted, this driving | running route will be registered into the route memory | storage area | region 251 as a daily route.

Therefore, in this embodiment, the following effects can be obtained.
(1) When the host vehicle travels, the departure point and the arrival point of the host vehicle are acquired. When the management data including the acquired departure place and arrival place is not stored in the table storage area 250 (daily route prediction management table), the management data is registered in the table storage area 250. On the other hand, when the management data including the acquired departure place and arrival place is stored in the table storage area 250, the number N of travels included in the management data is updated. Then, when management data (current management data) having the number of times of travel N equal to or greater than the starting point PS and the specified value Nth during the current vehicle travel is stored in the table storage area 250, the travel route of the host vehicle is acquired. Is started. In this state, when the host vehicle arrives at the arrival place PG included in the current management data, acquisition of the travel route of the host vehicle is terminated, and the travel route is stored in the route storage area 251 as the daily route. Is allowed.

  In the present embodiment, the “specified value Nth” is a determination value for determining whether or not the travel route on which the host vehicle will travel is an everyday route. Therefore, when it is determined that there is a possibility that the host vehicle does not travel on the daily route, the travel route is not acquired. That is, even an opportunity for registering a travel route is not given. Therefore, registration of travel routes other than the daily route can be suppressed, and as a result, an increase in the storage amount stored in the route storage area 251 can be suppressed.

  (2) In the present embodiment, when the travel route is acquired, it is determined whether or not the current time has exceeded a determination time based on the arrival time TG included in the current travel route. When the current time exceeds the determination time and the current position of the host vehicle is not the arrival place PG, it is determined that the host vehicle is not traveling on the daily route, and acquisition of the travel route of the host vehicle is compulsory. Is finished. Then, storage (registration) of the travel route acquired so far in the route storage area 251 is restricted. Therefore, the control load of the control device 20 accompanying the acquisition of the travel route can be reduced by the amount that the acquisition of the travel route is forcibly terminated when it is determined that the host vehicle is not traveling on the daily route.

  (3) In the present embodiment, the management data (current management data) including the departure place PS, the departure time TS, and the number N of times of travel equal to or greater than the specified value Nth when the vehicle is traveling is stored in the table storage area 250. First, acquisition of the travel route of the host vehicle is started. On the other hand, when the management data (current management data) including the departure place PS, the departure time TS, and the number of times of travel N equal to or greater than the specified value Nth when the vehicle is traveling is not stored in the table storage area 250, It is determined that the current travel route of the vehicle may be a travel route other than the daily route, and the current travel route of the vehicle is not acquired. Therefore, acquisition of a travel route other than the daily route can be suppressed.

  (4) When the management data (current management data) that includes the departure place PS and departure time TS at the time of the current vehicle travel and the number N of travels is equal to or greater than the specified value Nth is stored in the table storage area 250 The current management data is read from the table storage area 250, and acquisition of the travel route of the host vehicle is started. Then, when the host vehicle arrives at the arrival place PG included in the current management data by the determination time based on the arrival time TG included in the current management data, the acquisition of the travel route is ended. The storage (registration) of the travel route thus acquired in the route storage area 251 is permitted.

  In addition, when the travel route is acquired and the ignition switch (not shown) of the host vehicle is turned off at a point other than the arrival point PG included in the current management data, the current travel route is stored in the route storage area. 251 is not stored (registered). This is because the previous travel route is erased from the RAM 222 when the ignition switch (not shown) is turned on next time. Therefore, the possibility that other travel routes other than the daily route are registered can be reduced.

  (5) Even if the travel route corresponding to the current management data is stored in the route storage area 251, the current travel route is different from the travel route (daily route) stored in the route storage area 251. Sometimes, storage (registration) of the current travel route in the route storage area 251 is permitted. Therefore, the newly acquired travel route can be stored (registered) in the route storage area 251 as the daily route.

In addition, you may change the said embodiment into another embodiment as follows.
In the embodiment, when the acquisition of the current travel route is completed and the registered number F is acquired (steps S33 and S36: YES), the time when the acquisition is completed and the current management data include The arrival time TG may be compared. If the time when the acquisition is completed is a time before the arrival time TG included in the current management data, the host vehicle may have traveled the shortest route from the departure point PS to the arrival point PG. . Therefore, when the time when the acquisition is completed is before the arrival time TG included in the current management data, the replacement of the daily route to the current travel route may be permitted. In this case, the travel route that requires the shortest time required from the departure point PS to the arrival point PG can be stored (registered) in the route storage area 251 as an everyday route.

  In the embodiment, when the acquisition of the current travel route is completed and the registered number F is acquired (steps S33, S36: YES), the time required for the current travel is determined as the travel time ("current travel It may also be acquired as “time”. Then, an estimated travel time (= TG−TS) based on the departure time TS and arrival time TG included in the current management data may be calculated, and the predicted travel time may be compared with the current travel time. If the current travel time is less than the expected travel time, the host vehicle may travel on the shortest route from the departure point PS to the arrival point PG. Therefore, when the current travel time is less than the expected travel time, replacement of the daily route with the current travel route may be permitted. In this case, the travel route that requires the shortest time required from the departure point PS to the arrival point PG can be stored (registered) in the route storage area 251 as an everyday route.

  In the embodiment, the management data may have a data configuration that does not include the arrival time TG. In this case, the determination time may be set as shown below. For example, a recommended route (recommended route) from the departure point PS to the arrival point PG included in the current management data is searched, and travel required when the vehicle travels from the departure point PS to the arrival point PG along the recommended route. Time (also referred to as “estimated travel time”) is estimated. Then, the estimated travel time may be added to the departure time TS included in the current management data, and the determination time may be set based on the time based on the addition result. The determination time may be a time obtained by adding the estimated traveling time to the departure time TS included in the current management data. The determination time may be a time obtained by adding an estimated travel time and a reference time (for example, 30 minutes) to the departure time TS included in the current management data.

  The determination time may be a time based on a value obtained by adding the estimated travel time to the time at which the acquisition of the travel route is started. Note that the determination time may be a time obtained by adding an estimated travel time and a reference time (for example, 30 minutes) to a time at which acquisition of a travel route is started.

  In the embodiment, the management data may have a data configuration that does not include the departure time TS. In this case, in step S28, it is determined whether or not the management data including the departure place at the start of the current travel is in the daily route prediction management table.

  In the embodiment, during the acquisition of the travel route, the predicted arrival time from the current position to the arrival place PG may be acquired as forced termination determination information. In this case, the forced termination condition may be “the predicted arrival time has exceeded the determination time based on the arrival time TG”. If comprised in this way, acquisition of a driving | running route can be forcedly terminated at an earlier timing than the case of the said embodiment.

  In the embodiment, during acquisition of the travel route, whether or not the route on which the vehicle is currently traveling is in a traffic jam may be acquired as forced termination determination information. Road traffic information such as traffic congestion may be acquired by VICS (registered trademark) or the like. The forced termination condition in such a case may be “the route on which the vehicle is currently traveling is in a traffic jam”. VICS (registered trademark) is an abbreviation for “Vehicle Information and Communication System”.

  In the embodiment, a recommended route from the departure place PS to the arrival place PG included in the current management data may be searched. Then, the shortest distance from the recommended route to the current position of the host vehicle is acquired, and when the shortest distance is equal to or greater than a predetermined distance (for example, 300 m), the acquisition of the travel route is forcibly terminated. May be. In this case, the shortest distance from the recommended route to the current position of the host vehicle corresponds to the forced termination determination information, and “the shortest distance is equal to or greater than the specified distance” corresponds to the forced termination condition. When the host vehicle is traveling on the recommended route, the shortest distance is “0 (zero)” or a value close to “0 (zero)”.

At this time, the recommended route from the departure place PS to the arrival place PG included in the current management data may be one or plural (for example, five).
In the embodiment, each process of steps S34 and S35 may be omitted.

In the embodiment, when the determination result in step S36 is YES, the current travel route may be automatically stored in the route storage area 251 as the daily route.
In the embodiment, when the determination result of step S36 is NO and the determination result of step S38 is YES, the current daily route may be automatically replaced with the current travel route.

In the embodiment, the specified value Nth may be an arbitrary integer other than “10” (for example, 15) as long as it is an integer of “2” or more.
The route registration device of the present invention may be embodied in a server device that can communicate with the in-vehicle navigation device 11. In this case, it is preferable that the server device has a function capable of acquiring the current position of the vehicle.

The route registration device of the present invention may be embodied in a system that includes a server device having a function of specifying the position of a vehicle and an information terminal that communicates with the server device.
