  The driving habit DB 24 is connected to the driving habit specifying unit 32 and the charging plan creating unit 33 and stores driving habits in which the vehicle specified by the driving habit specifying unit 32 is used. The driving habit is a driving tendency by the driver at a predetermined time (24 hours, one week, one month, etc.), and the driving situation (average driving time, average driving distance, driving) in the driving habit DB 24 for each predetermined period. Time zone) is stored.

  Specifically, as shown in FIG. 5, the driving habit DB 24 indicates that “the average number of driving days per month, the average driving time of the day, the average driving distance of the day, the driving time zone, the frequency information of the destination (setting Etc.) ”is stored. FIG. 5 is a diagram illustrating an example of information stored in the driving habit DB.

  The control unit 30 has a memory for storing a control program, a program defining various processing procedures, and necessary data, and in particular, a travel history storage unit 31, a driving habit identification unit 32, and a charging plan creation unit. 33 and the charge plan execution part 34, and various processes are performed by these.

  Further, the control unit 30 is connected to a drive motor of the vehicle, and when a starter (ignition key or the like) is turned on, the controller 30 outputs the electricity stored in the rechargeable battery 21 to the drive motor, and according to the accelerator opening. , Adjust its output amount.

Specifically, the travel history storage unit 31 includes vehicle travel information from the camera 12, GPS receiver 13, VICS receiver 14, drive recorder 15, vehicle speed sensor 16, acceleration sensor 17, brake sensor 18, car navigation 19, and the like. For example, date / time, destination, travel distance, speed, acceleration, image, and drive recorder travel data are acquired. Then, the travel history storage unit 31 extracts from the acquired travel information of the vehicle, such as “date and time, day of the week, destination, distance”, “when and how far” the travel history DB 23 extracts. To store.

  The driving habit specifying unit 32 specifies a driving habit in which the vehicle is used from the driving history of the vehicle. Specifically, the driving habit identification unit 32 determines, based on the travel history stored in the travel history DB 23, “what date and day of the week, what time zone, what distance A driving habit indicating whether the vehicle is traveling to a place is specified, and the specified driving habit is stored in the driving habit DB 24. For example, the driving habit identification unit 32 may determine, based on the driving history stored in the driving history DB 23, “average driving days per month, average driving time per day, average driving distance per day, driving time zone, destination Is specified and stored in the driving habits DB 24.

  In addition, the driving habit specifying unit 22 acquires the driving history from the driving history DB 23 in units of one week or one day (24 hours), and specifies driving habits in units of one week or one day. Also good. That is, the driving habit specifying unit 32 can specify the driving habits in arbitrary units according to the driving cycle in which the driver drives the car, and thus can specify appropriate driving habits.

  The charging plan creation unit 33 creates a charging plan for charging the vehicle with electric energy based on the driving habits specified by the driving habit specifying unit 32. Specifically, the charging plan creation unit 33 considers the specified driving habits, the remaining amount at the local point, the electricity bill, etc., while maintaining the amount of electricity that can be operated immediately, and the charging plan that can be charged as cheaply as possible, Create a charging plan that charges only the amount of electricity that can be operated immediately in a short time and reduces the cost of the remaining charge. For example, as shown in FIG. 6, the charging plan creation unit 33 charges at night when the electricity bill is low, and the plan “19:00 to 21:00: standby for supplying electricity to other electrical appliances in other time zones” , 21: 00-24: 00: Power (electricity) supply to other electrical appliances, 24: 00-6: 00: Charging ”and plan“ 19: “00 to 22:00: Supply power (electricity) to other electrical appliances, 22:00 to 4:00: Charge until XXW, 4:00 to 6:00: Standby”, etc. The created charging plan may be stored in a memory or the like. FIG. 6 is a diagram illustrating an example of a charging plan to be created.

  Moreover, the charging plan preparation part 33 can set arbitrarily the plan period and preparation timing of the plan mentioned above. Specifically, the charging plan creation unit 33 charges the battery in one week, that is, how to charge the battery in one week from Monday to Sunday, or how in each day of the week from Monday to Sunday. It is possible to create a weekly charging plan such as whether to charge the battery. However, the unit of one week shown here is merely an example, and can be arbitrarily set, for example, a unit of one day or a unit of driving habits specified by the driving habit specifying unit 22. In consideration of the fact that many people generally drive on a weekly basis or on a daily basis, an appropriate plan can be created by creating a period as described above.

  Further, the charging plan creation unit 33 may review the charging plan created every predetermined time (for example, every 6 hours). For example, the charging plan creation unit 33 confirms the actual charging capacity (remaining amount) every 6 hours, and reviews the created charging plan in units of one week or one day. Check. Then, for example, when the charging time is large but the remaining amount is large or the charging time is not long but the remaining amount is small, the charging plan creating unit 33 re-creates the charging plan. By doing in this way, the charge plan according to the actual charge (power storage) status can be created, and the created plan can be updated according to the actual charge (power storage) status.

  The charge plan execution unit 34 charges the vehicle with electric energy according to the charge plan created by the charge plan creation unit 33. Specifically, when the charging plug 25 is connected to a household outlet or a vehicle charging outlet, the charging plan execution unit 34 acquires the charging plan created by the charging plan creation unit 33 and the like, The rechargeable battery 20 is charged with electric energy along For example, the charge plan execution unit 34 may have a charge plan of “19: 00-21: 00: Standby, 21: 00-24: 00: Supplying power (electricity) to other electrical appliances, 24: 00-6: 00: 00: In the case of “charging”, even if the charging plug 21 is connected to a household outlet, a vehicle charging outlet, or the like, the charging is not performed until 21:00. Then, the charging plan execution unit 34 supplies the electricity stored in the rechargeable battery 21 to other electrical appliances (electricity) via a charging plug or an outlet between 21:00 and 24:00. Thereafter, the charging plan execution unit 34 starts charging at 24:00 and ends at 6:00.

  The charge plan execution unit 34 can also notify the driver of the execution of the charge plan created by the charge plan creation unit 33. Specifically, the charging plan execution unit 34 notifies the entire charging plan when the engine is stopped, when it arrives at the destination or home, when the charging is scheduled, when the engine is started, Connect the plug "etc.). Moreover, the charging plan execution part 34 may notify with an audio | voice and may display on a display with an image.

[Processing by in-vehicle device]
Next, processing by the in-vehicle device will be described with reference to FIG. FIG. 7 is a flowchart illustrating the flow of the charging plan process in the in-vehicle device according to the first embodiment.

  As illustrated in FIG. 7, when the driving habit identification unit 32 of the in-vehicle device 10 receives the charging plan creation start instruction (Yes in step S101), the driving history storage unit 31 uses the traveling history stored in the traveling history DB 23. The driving habit is specified (step S102).

  For example, the driving habit identification unit 32 is set by the user when the position of the vehicle approaches the vicinity of the home, when a user's start instruction is received, or when a predetermined cycle such as one month or one week is reached. Identify driving habits at any time.

  Subsequently, the charging plan creation unit 33 of the in-vehicle device 10 creates a charging plan for charging the vehicle with electric energy based on the driving habits specified by the driving habits specifying unit 32 (step S103).

  Thereafter, when the vehicle is parked and the charging plug 25 is connected to a household outlet, a vehicle charging outlet, or the like (Yes at step S104), the charging plan execution unit 34 sets the charging plan created by the charging plan creation unit 33. Therefore, the electric energy is charged in the rechargeable battery 21 (step S105).

  Then, when the charging plan execution unit 34 detects that the engine (drive motor) has been started during charging in step S105 (Yes in step S106), the charging plan execution unit 34 ends the charging (step S107).

[Effects of Example 1]
As described above, according to the first embodiment, it is possible to omit unnecessary charging, to perform charging at night when the electricity bill is cheap, or to provide surplus electricity to other electric devices. It is possible to efficiently charge a vehicle that uses electricity as energy, such as an electric vehicle. Moreover, since it charges with the charge plan created based on the driving | operation habit, when it wants to drive, the charge amount which can be drive | operated immediately can be ensured.

  By the way, in Example 1, although the example which performs a series of processing which specifies driving habits of vehicles, creates a driving plan, and performs charge by an in-vehicle device was explained, this application is not limited to this, Some processing can be performed by the center.

  Therefore, in the second embodiment, a processing flow of the in-vehicle system that creates a charging plan using the center will be described with reference to FIG. FIG. 8 is a sequence diagram showing a processing flow of the in-vehicle system that creates a charging plan using the center.

  As shown in FIG. 8, the in-vehicle device 10 obtains information from the camera 12, GPS receiver 13, VICS receiver 14, drive recorder 15, vehicle speed sensor 16, acceleration sensor 17, brake sensor 18, car navigation 19 and the like as needed. Then, the travel history is stored in the travel history DB 23 as needed (step S201).

  The in-vehicle device 10 can be set to any user, such as when the position of the vehicle approaches the vicinity of the home, when a user's start instruction is received, or when a predetermined cycle such as one month or one week is reached. When predetermined triggers such as various triggers are reached (Yes at Step S202), the travel history is acquired from the travel history DB 23 and transmitted to the center (Step S203).

  Thereafter, the center specifies the driving habits of the vehicle that has transmitted the driving history based on the driving history acquired from the in-vehicle device 10 (step S204), and the charging plan created based on the specified driving habits is stored in the in-vehicle device 10. Transmit (step S205). As described above, the center can uniquely identify a vehicle by exchanging information using a wireless communication device assigned an identifier (for example, vehicle ID) from a management company that manages the center. it can.

  And the vehicle-mounted apparatus 10 receives a charge plan from a center (step S206), and performs charge according to the received charge plan (step S207).

  By doing in this way, while being able to reduce the processing load by the vehicle-mounted apparatus side, a charge plan can be collectively managed by the center side. Therefore, the user can access the center using the Internet or the like to check the charging plan of his / her vehicle from his home or the like, and can change the charging plan as necessary. When the charging plan is changed, the center supplies electricity to a part of the communication port of the in-vehicle device whose motor (engine) is stopped, and distributes the changed charging plan to the in-vehicle device. You can also. Thus, convenience for the user is improved.

  The center can collect charging plan information for many vehicles. Therefore, in the center, in order to prevent the charging facility in the facility from being full, it is possible to provide guidance to each vehicle in consideration of the empty state of the charging facility. The vacant state of the charging facility is grasped by, for example, judging from the charging schedule of each vehicle. As another method, a communication network is constructed between the center and the charging facility, and it is possible to collect information on the usage status of the charging facility at the center and grasp the vacant state of the charging facility.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above. Therefore, as shown below, (1) regenerative planning, (2) battery characteristics, (3) sending to the owner, (4) system configuration, etc., (5) different examples will be described by dividing them into programs. .

(1) Regenerative planning For example, when creating a charging plan, an in-vehicle device or center predicts the destination of the next day from driving habits, and determines the gradient from the home (vehicle parking location) to the destination as navigation information or HDD. Check from the map data. And the in-vehicle device or center should create a charging plan that does not charge the amount that can be charged by regeneration, considering the amount and location that can be charged by regeneration, such as many downhills, entering the downhill immediately from home, etc. You can also.

  As a specific example, the in-vehicle device or the center stores map data including gradient data shown in the following table in an HDD or the like. The “road link ID” shown in the following table is information (road characteristic data) that specifies roads separated by predetermined sections such as intersections, and the “start node position” is specified by the road link ID. The “end node position” is the end position of the road specified by the road link ID. The “link length” is information indicating the length (distance) from the start node position to the end node position, and the “reference power amount” is used to travel on the road specified by the road link ID. This is the amount of power that is required. When power is obtained by regeneration, it is indicated by “+ power amount”, and when power is not obtained by regeneration (only consumed), it is indicated by “−power amount”. It is to be noted that nodes (road position data) indicate the ends of roads such as intersections, and lines connecting the nodes are links (road characteristic data indicating distances and road characteristics). Set by the designer to be done properly.

  By holding such data, the in-vehicle device or the center can grasp how much power is consumed and how much can be recovered in the travel route from the current location of the vehicle to the destination. Considering the amount and location that can be charged, it is possible to create a charging plan such as not charging the amount that can be charged by regeneration.

  In addition, instead of gradient data (table (1)), a method of directly storing regenerative data (electricity consumption, regenerative amount) in association with each other is also conceivable. In this case, the regenerative reference value is directly stored as regenerative data, and is corrected with a predetermined correction value for each vehicle type (for example, the reference value and the correction value are integrated) to obtain the actual regenerative amount.

  For example, assume that the reference value is “X”, the correction value of the electric vehicle is “Y”, and the correction of the hybrid automatic person is “Z”. Further, “X” is stored in the center or in-vehicle device in association with the “road link ID, start node position, end node position, link length” described above. In this case, the regeneration value can be calculated with “X × Y” for an electric vehicle, and the regeneration value can be calculated with “X × Z” for a hybrid vehicle. By doing so, as in the case described above, the in-vehicle device or the center can grasp how much power is consumed and how much can be recovered in the travel route from the current location of the vehicle to the destination. Considering the amount and location that can be charged, it is possible to create a charging plan such as not charging the amount that can be charged by regeneration.

(2) Battery characteristics The in-vehicle device or the center can also create a charging plan in consideration of the characteristics of the rechargeable battery 21 mounted on the vehicle. For example, in the case of the rechargeable battery 21 that is severely deteriorated if electricity is not charged more than a predetermined value, when the charging plug 25 is connected to an outlet or the like, it is immediately charged up to a predetermined value (predetermined value + α). A simple charging plan can be created. In addition, it is possible to control the regenerative charging so that the remaining amount does not always become a predetermined value (predetermined value + α) or less.

  In this case, the storage amount is detected, and the charging time is calculated so that the storage amount is a predetermined value + α. In addition, since there is a case where the vehicle needs to run suddenly, it is desirable to set α so that the storage amount has a certain margin.

(3) Sending to owner The in-vehicle device or the center can also transmit the created charging plan to the owner's mobile terminal by possessing the mobile terminal address of the vehicle owner. Further, as described above, even when the created charging plan is changed, the changed charging plan can be transmitted to the owner's mobile terminal.

(4) System configuration etc. In addition, among the processes described in the present embodiment, all or part of the processes described as being automatically performed can be manually performed or manually performed. All or a part of the processing described as a thing can also be automatically performed by a known method. In addition, when performing manually, it is desirable to perform notification (display / sound) of a charging plan using the display 40, the speaker 50, or the like. In addition, the processing procedures, control procedures, specific names, and information including various data and parameters (for example, FIG. 3 to FIG. 6) shown in the above documents and drawings are optional unless otherwise specified. Can be changed.

  Each component of each illustrated device is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. It can be configured by integrating (for example, integrating the charging plan creation unit 33 and the charging plan execution unit 34). Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

(5) Program The charging plan creation method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.
