As shown in FIG. 1, the charging control device 100 according to the first embodiment includes a vehicle position detection device 110, a battery controller 120, a battery 125, an in-vehicle communication device 130, and an in-vehicle control device 140. In FIG. 1, for the sake of convenience of explanation, only the charging control device 100 mounted on the own vehicle is displayed. However, in the present embodiment, a plurality of vehicles including the own vehicle include the charging control device illustrated in FIG. 1. Accordingly, these vehicles can exchange information with each other via the in-vehicle communication device 130.

  The own vehicle position detection device 110 includes a GPS unit, a gyro sensor, a vehicle speed sensor, and the like, detects radio waves transmitted from a plurality of satellite communications by the GPS unit, and periodically acquires position information of the own vehicle. In addition, the current position of the host vehicle is detected based on the acquired position information of the host vehicle, the angle change information acquired from the gyro sensor, and the vehicle speed acquired from the vehicle speed sensor. The position information of the own vehicle detected by the own vehicle position detection device 110 is transmitted to the in-vehicle control device 140.

  The battery controller 120 charges the battery 125 based on the detection values of a voltage sensor (not shown) and a current sensor (not shown) connected to the battery 125 and a temperature sensor (not shown) that detects the temperature of the battery 125. The amount (SOC) is calculated, and the calculated charge amount (SOC) of the battery 125 is transmitted to the in-vehicle controller 140.

  The in-vehicle communication device 130 directly performs communication between the own vehicle and another vehicle by inter-vehicle communication without using an external server. Specifically, the in-vehicle communication device 130 acquires the charge amount (SOC) of the battery 125 of the host vehicle from the in-vehicle control device 140, and the acquired charge amount (SOC) of the battery 125 of the host vehicle is obtained by inter-vehicle communication. Send to other vehicles. In-vehicle communication device 130 receives the charge amount (SOC) of the battery of the other vehicle from the other vehicle by inter-vehicle communication, and outputs the received charge amount (SOC) of the battery of the other vehicle to in-vehicle control device 140. .

  The in-vehicle control device 140 determines a priority order of the battery 125 of the host vehicle when the battery 125 is charged by the charger 200, and a program for presenting information based on the priority order to the user of the charger 200. ROM (Read Only Memory) stored, CPU (Central Processing Unit) as an operation circuit for executing a program stored in the ROM, and RAM (Random Access Memory) functioning as an accessible storage device I have. As an operation circuit, instead of or in addition to a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. Can be used.

  And the vehicle-mounted control apparatus 140 implement | achieves a vehicle information acquisition function, a charge order determination function, and a charge information presentation function by running the program stored in ROM by CPU. Below, each function which the vehicle-mounted control apparatus 140 implement | achieves is demonstrated.

  The vehicle information acquisition function of the in-vehicle control device 140 acquires the charge amount (SOC) of the battery 125 of the other vehicle transmitted from the other vehicle by inter-vehicle communication. Specifically, as shown in FIG. 2, the vehicle information acquisition function exists in the processing target range when the host vehicle enters the processing target range that is within a predetermined distance from the position of the charger 200. The battery charge amount (SOC) of the other vehicle existing in the processing target range is obtained from the other vehicle existing in the processing target range by inquiring the battery charge amount (SOC) to the other vehicle. get. For example, in the example shown in FIG. 2, the vehicle information acquisition function calculates the charge amount (SOC) of the battery 125 of the other vehicle A and the charge amount (SOC) of the battery 125 of the other vehicle B that exist within the processing target range. Can be acquired. In addition, FIG. 2 is a figure for demonstrating the charge control process which concerns on this embodiment.

  The processing target range includes the position of the charger 200 and is not particularly limited as long as it is set with reference to the position of the charger 200. For example, a radius of 10 meters centered on the position of the charger 200 is used. Range. In the present embodiment, the position information of the charger 200 is stored in advance in the RAM of the in-vehicle control device 140, and the vehicle information acquisition function is based on the position information of the charger 200 stored in the RAM. A range can be set. Moreover, it is possible to detect that the vehicle is stopped in a specific parking space by detecting the presence of a marker provided in the parking space, for example, without using a GPS system as the vehicle position detection device 110 By using a simple parking position detection device, it can also be determined that the vehicle is stopped in a parking space where charging by the charger 200 is possible, that is, the host vehicle has entered the processing target range.

  Further, the vehicle information acquisition function is performed when the preparatory operation for starting the charging of the battery 125 is performed, for example, when the power feeding connector of the charger 200 is disconnected from the power receiving connector of another vehicle. Inquires about the amount of charge (SOC) of the battery with respect to other vehicles existing in the processing target range by acquiring information that the preparation operation has been performed from the other vehicle from which the power supply connector is removed. Thus, it is also possible to obtain a charge amount (SOC) of the battery of the other vehicle existing in the processing target range from the other vehicle existing in the processing target range.

  Furthermore, the vehicle information acquisition function also acquires the position information of the host vehicle and the amount of charge (SOC) of the battery 125 of the host vehicle. Specifically, the vehicle information acquisition function acquires the position information of the own vehicle detected by the own vehicle position detection device 110 from the own vehicle position detection device 110, and the vehicle information calculated by the battery controller 120. The amount of charge is acquired from the battery controller 120.

  The charge order determination function of the in-vehicle control device 140 compares the charge amount (SOC) of the own vehicle acquired by the vehicle information acquisition function with the charge amount (SOC) of another vehicle existing in the processing target range. Thus, the priority of the battery 125 of the own vehicle when the battery 125 is charged by the charger 200 is determined.

  Specifically, the charging order determination function sets a priority order when charging the battery 125 by the charger 200 for a battery 125 having a lower charge amount (SOC) among a plurality of vehicles existing within the processing target range. Judge high. For example, the charging order determination function determines a vehicle having the lowest charge amount of the battery 125 among a plurality of vehicles existing in the processing target range as a vehicle having the highest order of charging the battery 125, The vehicle with the next lowest charge amount is determined as the vehicle with the next highest order for charging the battery 125 of the host vehicle (the vehicle with the second highest order for charging the battery 125). Similarly, the charging order determination function also determines a vehicle whose order of charging the battery 125 is the third or later. In this way, the charging order determination function determines the priority order of the battery 125 of each vehicle when the battery 125 is charged by the charger 200.

  The charging information presentation function of the in-vehicle control device 140 presents information based on the priority determined by the charging order determination function to the user of the charger 200. For example, the charging information presentation function gives priority to charging of the battery 125 of the own vehicle when it is determined that the priority of the battery 125 of the own vehicle is the highest among the plurality of vehicles existing in the processing target range. Information indicating that the operation is to be performed can be presented to the user of the charger 200 as information based on the priority order of the battery 125 of the host vehicle.

  In addition, when the charging information presentation function is not the highest in the order of charging the battery 125 of the own vehicle among the plurality of vehicles existing in the processing target range, the order of the battery 125 of the own vehicle (for example, second). Such information may be presented to the user of the charger 200 as information based on the rank of the battery 125 of the host vehicle. Or it is good also as a structure which shows the information of the other vehicle with the highest order | rank which charges the battery 125 with respect to the user of the charger 200 as information based on the order | rank of the battery 125 of the own vehicle.

  Moreover, the user of the charger 200 is a person who actually charges the battery 125 of the own vehicle using the charger 200. For example, the driver himself charges the battery 125 in the charging information presentation function. In this case, information based on the rank of the battery 125 of the host vehicle can be presented to a driver who is a user of the charger 200 via a display or a speaker (not shown).

  On the other hand, for example, when a person other than the driver, such as an employee of a car rental store or a car sharing store, charges the battery 125, the charging information presentation function displays the battery 125 of the own vehicle on the display provided in the charger 200. By presenting the information based on the priority order, the information based on the order of the battery 125 of the host vehicle can be presented to the user of the charger 200 other than the driver. Alternatively, when a person other than the driver charges the battery 125, the charging information presentation function charges the vehicle other than the driver by lighting or blinking the dashboard, headlight, blinker, hazard, etc. of the own vehicle. Information based on the priority of the battery 125 of the host vehicle can be presented to the user of the device 200.

  Then, with reference to FIG. 3, the charge control process which concerns on 1st Embodiment is demonstrated. FIG. 3 is a flowchart showing the charging control process according to the first embodiment. Note that the charging control process shown in FIG. 3 is executed by the in-vehicle control device 140 when, for example, the main power switch of the vehicle is turned on.

  In step S101, the position information of the host vehicle is acquired by the vehicle information acquisition function. In step S102, the vehicle information acquisition function determines whether or not the host vehicle has entered the processing target range based on the position information of the host vehicle acquired in step S101. If it is determined that the host vehicle has not entered the processing target range, the process returns to step S101, and the above-described processing is repeated until the host vehicle enters the processing target range. On the other hand, as shown in FIG. 2, when it is determined that the host vehicle has entered the processing target range, the process proceeds to step S103.

  In step S103, the charge amount (SOC) of the battery 125 of the other vehicle is acquired by the vehicle information acquisition function. Specifically, the vehicle information acquisition function exists in the processing target range by inquiring about the amount of charge (SOC) of the battery 125 to other vehicles existing in the processing target range by inter-vehicle communication. The charge amount (SOC) of the battery 125 of the other vehicle to be acquired is acquired. In step S104, the charge amount (SOC) of the battery 125 of the host vehicle is acquired by the vehicle information acquisition function.

  And in step S105, the priority of the battery 125 of the own vehicle at the time of charging the battery 125 by the charger 200 is determined by the charging order determination function. Specifically, the charge order determination function compares the charge amount (SOC) of the other vehicle acquired in step S103 with the charge amount (SOC) of the own vehicle acquired in step S104, and By determining the priority order of the battery 125 of each vehicle so that the priority of the vehicle with a lower charge amount is higher, the priority order of the battery 125 of the own vehicle when the battery 125 is charged by the charger 200 is determined. To do.

  In step S106, based on the determination result in step S105, the charging priority determination function determines whether the charging priority of the battery 125 of the host vehicle is the highest among a plurality of vehicles existing within the processing target range. Judgment is made. As a result of the determination in step S105, if the priority of the battery 125 of the own vehicle is the highest, the process proceeds to step S107. On the other hand, if the priority of the battery 125 of the own vehicle is not the highest, the process proceeds to step S108. .

  In step S107, since it is determined that the priority of the battery 125 of the own vehicle is the highest among the plurality of vehicles existing within the processing target range, the battery 125 of the own vehicle is prioritized by the charging information presentation function. And charging information is presented to the user of the charger 200.

  For example, when the driver himself charges the battery 125, the charging information presentation function provides information indicating that the battery 125 of the host vehicle is preferentially charged via a display or a speaker (not shown). Can be presented against. In addition, the charging information presentation function presents information indicating that the battery 125 of the host vehicle is preferentially charged on a display provided in the charger 200 when a person other than the driver charges the battery 125, for example. Alternatively, by turning on or blinking the dashboard, headlight, blinker, hazard, etc. of the host vehicle, charging of the battery 125 of the host vehicle is given priority to the user of the charger 200 other than the driver. Information can be presented.

  On the other hand, when it determines with the priority of the battery 125 of the own vehicle not being the highest in step S106, it progresses to step S108. In step S <b> 108, information indicating that the charging of the battery 125 of the other vehicle is preferentially performed is presented to the user of the charger 200 by the charging information presentation function. For example, the charging information presentation function presents information on other vehicles having the highest priority for charging the battery 125 among a plurality of vehicles existing within the processing target range to the user of the charger 200. Thereby, the user of the charger 200 can determine which vehicle battery 125 needs to be charged with the highest priority.

  As described above, in the first embodiment, the charge amount (SOC) of the battery 125 of the other vehicle existing in the processing target range is acquired by inter-vehicle communication, and the charge amount of the battery 125 of the host vehicle and the processing target are acquired. By comparing the amount of charge of the battery 125 of the other vehicle existing within the range, the order of charging the battery 125 of the host vehicle is determined among the plurality of vehicles existing within the processing target range around the charger 200. To do. And when it determines with the order | rank which charges the battery 125 of the own vehicle having the highest order, it is the information that it preferentially charges the battery 125 of the own vehicle with respect to the user who uses the charger 200. Present. Thereby, in this embodiment, the user of the charger 200 can be made aware of the vehicle that needs to be preferentially charged with the battery 125, and the charging efficiency of the vehicle with the charger 200 can be improved. . Moreover, in this embodiment, since the charge amount of the battery 125 of another vehicle is acquired by inter-vehicle communication, it is possible to determine a vehicle that needs to be preferentially charged without going through a server. The amount of communication between the server and the vehicle can be reduced, and the management cost of the entire system can be reduced.

  Moreover, in this embodiment, when the own vehicle enters the processing target range, or when a preparatory operation for using the charger 200 is performed, from the other vehicle existing in the processing target range, By receiving information such as the amount of charge (SOC) of the battery 125, the vehicle-to-vehicle communication between the host vehicle and the other vehicle can be kept to the minimum necessary, and thereby the communication load of the vehicle-to-vehicle communication with the other vehicle. Can be reduced.
