External charging (AC charging) can be performed. Note that the AC power supply device 91 is configured as a power supply device having a household power supply or an industrial power supply, for example.

  Charging relay CHR is provided between battery 36 and charger 41 in power line 39. This charging relay CHR is on / off controlled by the ECU 50 to connect and disconnect the battery 36 and the charger 41.

  The air conditioner 44 performs air conditioning in the passenger compartment. The air conditioner 44 is connected to the power line 39 and is operated by the power from the battery 36. The air conditioner 44 is controlled by the ECU 50.

  The display 48 is attached in front of the driver's seat in the passenger compartment, and displays various information related to the vehicle. The display 48 is controlled by the ECU 50.

  Although not shown, the ECU 50 is configured as a microprocessor centered on a CPU. In addition to the CPU, a ROM that stores processing programs, a RAM that temporarily stores data, an input / output port, a communication port, a data center, and the like. And a communication module that always communicates with 70.

  Various signals are input to the ECU 50 through an input port. Examples of the signal input to the ECU 50 include a rotational position θm of the rotor of the motor 32 from a rotational position detection sensor that detects the rotational position of the rotor of the motor 32, and a voltage sensor attached between terminals of the battery 36. The voltage Vb of the battery 36 from 36a, the current Ib of the battery 36 from the current sensor 36b attached to the output terminal of the battery 36, and the connection for detecting whether or not the vehicle side connector 42 is connected to the power supply side connector 92 A connection signal from the sensor 43, an outside air temperature Tat from the temperature sensor 52 that detects the outside air temperature, a seating signal Ss from the seating sensor 54 that detects the seating of the driver or passenger on the seat, and the current position information of the vehicle Various information from the navigation device 56 that provides route guidance using the set location information of the destination and the stored map information.

Examples of the signal output from the ECU 50 include a control signal to the inverter 34, a control signal to the system main relay SMR, a control signal to the charging relay CHR, a control signal to the charger 41, and an air conditioner 44. A drive signal, a display signal to the display 48, etc. can be mentioned. The ECU 50 calculates the storage ratio SOC of the battery 36 based on the integrated value of the current Ib of the battery 36 from the current sensor 36b. Various data are constantly output from the ECU 50 to the data center 70 via the communication module. The various data include, for example, the outside air temperature Tat detected by the temperature sensor 52, the use status of the vehicle (for example, the date and time (departure date and time) DT when the vehicle was turned on and started running, and the position of the vehicle from the navigation device 56 Information and destination location information).

   In the electric vehicle 20 of the embodiment configured as described above, when the ignition switch is turned on by the user (driver), the ECU 50 turns on the system main relay SMR to make it ready for traveling. When the system main relay SMR is thus turned on, the motor 32 is driven and controlled according to the accelerator operation of the user. When the ignition switch is turned off, the system main relay SMR is turned off to be ready-off.

  Further, in the electric vehicle 20 of the embodiment, the ECU 50 allows the user to connect the vehicle side connector 42 and the power supply side connector 92 from the charging point 90 when the ignition switch is off at the charging point 90 such as at home or a charging station.

  The data center 70 configured in this manner always communicates with the electric vehicle 20 and inputs various data from the electric vehicle 20 to the server 72 via the network 12 such as the Internet. The server 72 stores in the storage 74 occupant behavior patterns based on various input data. As a behavior pattern, when the departure date and time DT is a weekday morning, it moves from the home to the workplace without stopping at a parkingable facility such as a convenience store along the road. When the departure date and time DT is a holiday morning, it goes to the convenience store every time. Stop and stop shopping. If it is detected from the image signal Spic that the passenger is a woman and the face is not covered with makeup, the passenger will stay in the car without getting off even if he / she stops at the convenience store. And so on.

  Next, the operation of the vehicle system 10 of the embodiment configured as described above, particularly the operation during traveling will be described. FIG. 3 is a flowchart illustrating an example of a prediction processing routine executed by the server 72 of the data center 70. FIG. 4 is a flowchart showing an example of a display processing routine executed by the ECU 50 of the electric vehicle 20. First, the prediction processing routine of FIG. 3 will be described, and then the display processing routine of FIG. 4 will be described.

  The prediction processing routine illustrated in FIG. 3 is always executed. When the prediction process routine is executed, the server 72 of the data center 70 executes a process of inputting the outside air temperature Tat, the departure date and time DT, the seating signal Ss, and the image signal Spic (step S100). As the outside air temperature Tat, the temperature detected by the temperature sensor 52 mounted on the electric vehicle 20 is input via communication via the network 12. The departure date and time DT is input from the ECU 50 of the electric vehicle 20. As the seating signal Ss, a signal detected by a seating sensor 54 mounted on the electric vehicle 20 is input via communication via the network 12. The image signal Spic is output from the monitor 58 mounted on the electric vehicle 20 via the network 12 by communication.

  Subsequently, it is predicted that the air conditioner 44 will operate while the vehicle is stopped based on the input outside air temperature Tat, departure date and time DT, seating signal Ss, image signal Spic, and occupant behavior patterns stored in the storage 74. (Step S110), the determination result Re is output to the electric vehicle 20 by communication via the network 12 (step S120), and this routine is terminated. The determination in step S110 is performed based on the input outside air temperature Tat, departure date and time DT, seating signal Ss, image signal Spic, and the action pattern stored in the storage 74. For example, when the departure date and time DT is a weekday morning, it is determined that the air conditioner 44 is not predicted to operate during parking because the home does not stop at a parking facility such as a convenience store along the road. In addition, it is detected that the departure date and time DT is a holiday morning and the passenger is present in the seating signal Ss, and it is detected from the image signal Spic that the passenger is a woman and no makeup is applied to the face. When Tat exceeds a threshold Tth (for example, 25 ° C., 27 ° C., 29 ° C., etc.) of the temperature at which the occupant feels hot, the customer stops at the convenience store, but the passenger stays in the car to apply makeup to the face. It is determined that the air conditioner 44 is expected to be operated during parking due to heat.

  Next, the display processing routine shown in FIG. 4 will be described. The display processing routine is executed when the ignition switch is turned on by the user (driver) and the system main relay SMR is turned on and ready (running). When this routine is executed, the ECU 50 of the electric vehicle 20 executes a process of inputting the determination result Re (step S200). The determination result Re is input from the data center 70 via the network 12 by communication.

  Subsequently, it is determined based on the determination result Re whether or not the air conditioner 44 is predicted to operate during parking (step S210). When the air conditioner 44 is not expected to operate during parking, information about the facility is displayed in order from the facility closest to the vehicle, such as a convenience store and a supermarket, that can be parked around the vehicle. The display 48 is controlled by outputting a display signal to the display 48 so that the information on the facility closer to the facility far from the vehicle among the plurality of facilities that can be parked around the vehicle is preferentially displayed. (Step S220), this routine is finished. In step S220, a plurality of facilities located at a predetermined distance from the current position of the vehicle are displayed in order from the closest facility using the current position of the vehicle from the navigation device 56 and the map information. By displaying information related to the facilities in order from the facility closest to the vehicle for the plurality of facilities that can be parked in this way, the convenience of the user (driver) can be enhanced.

  When it is predicted in step S210 that the air conditioner 44 is activated during parking, information on the facility is displayed in order from the facility having the charging point 90 for a plurality of facilities that can be parked around the vehicle such as a convenience store and a supermarket. That is, the display 48 is controlled so that information on the facility having the charging point 90 among the plurality of facilities that can be parked around the vehicle is preferentially displayed (step S230). Exit. In step S230, the distance from the current position of the vehicle to the facility having the charging point 90 for a plurality of facilities located at a predetermined distance from the current position of the vehicle using the current position of the vehicle and the map information from the navigation device 56 is determined. The facilities that do not have the charging point 90 are displayed in order from the closest one, and then the facilities that do not have the charging point 90 are displayed in order from the closest one from the current position of the vehicle. As the information regarding the facility, the same information as the process of step S220 may be displayed, or different information may be displayed. The user (driver) who sees such a display moves the vehicle to a facility having a charging station (external power supply device), charges the battery 36 with the power from the external power supply device, and the air conditioner operates during parking. To prepare for power consumption. Thereby, the fall of the electrical storage amount of the battery 36 during parking can be suppressed, and the fall of the travel distance of a vehicle can be suppressed.

  According to the electric vehicle 20 mounted on the vehicle system 10 of the present invention described above, when the air conditioner 44 is not expected to operate during parking, information on the facility closest to the vehicle among the plurality of facilities that can be parked. Control the display 48 so that it is displayed in preference to information relating to other facilities, and when it is predicted that the air conditioner 44 will operate during parking, it has a charging point 90 (having an AC power supply device 91). By controlling the display 48 so that the facility information is displayed in preference to the information of the facility that does not have the charging point 90 among the plurality of facilities, it is possible to suppress a decrease in the charged amount of the battery 36 during parking. it can.

  In the vehicle system 10 according to the embodiment, in the processing of steps S100 and S110 illustrated in FIG. 3, the input outside air temperature Tat, departure date and time DT, seating signal Ss, image signal Spic, and the occupant behavior pattern stored in the storage 74 Based on the above, it is determined whether or not the air conditioner 44 is predicted to operate while the vehicle is stopped. However, if it is determined whether or not the air conditioner 44 is predicted to operate while the vehicle is stopped based on at least one of the outside air temperature Tat, the departure date / time DT, the seating signal Ss, and the image signal Spic and the behavior pattern of the occupant. Therefore, for example, it may be determined whether or not the air conditioner 44 is predicted to operate while the vehicle is stopped based on the outside air temperature Tat and the occupant behavior pattern.

  In the vehicle system 10 according to the embodiment, in step S220 illustrated in FIG. 4, when it is not predicted that the air conditioner 44 operates during parking, the current position of the vehicle and the map information from the navigation device 56 are used. A plurality of facilities located at a predetermined distance from the current position are displayed in order from the nearest facility. However, the departure date and time DT may be used instead of the current position of the vehicle and the map information from the navigation device 56. A plurality of facilities may be displayed in order from the nearest facility using the departure date and time DT. In the case of using the departure date and time DT, the first relationship that is the relationship between the departure date and time DT, the plurality of facilities, and the order in which they are displayed is learned in advance. The facilities and the order in which they are displayed may be derived, and a plurality of facilities may be displayed in the derived order. Information on the facility can include information on the type of facility (convenience store, supermarket, etc.) and whether there are incidental facilities (charging station, tea space).

  In the vehicle system 10 according to the embodiment, in step S230 illustrated in FIG. 4, charging points are obtained for a plurality of facilities located at a predetermined distance from the current position of the vehicle using the current position of the vehicle and the map information from the navigation device 56. The facilities having 90 are displayed in order from the closest distance from the current position of the vehicle, and then the facilities not having the charging point 90 are displayed in order from the closest distance from the current position of the vehicle. However, the facility having the charging point 90 may be displayed randomly regardless of the current position of the vehicle.

  In the vehicle system 10 according to the embodiment, in step S230 illustrated in FIG. 4, charging points are obtained for a plurality of facilities located at a predetermined distance from the current position of the vehicle using the current position of the vehicle and the map information from the navigation device 56. The facilities having 90 are displayed in order from the closest distance from the current position of the vehicle, and then the facilities not having the charging point 90 are displayed in order from the closest distance from the current position of the vehicle. However, the departure date and time DT may be used instead of the current position of the vehicle and the map information from the navigation device 56. In this case, the second relationship, which is the relationship between the departure date and time DT, the plurality of facilities, and the order in which they are displayed, is learned in advance, and when the departure date and time DT is given, the plurality of facilities and them are displayed from the second relationship. What is necessary is just to derive the order to perform and to display a plurality of facilities in the derived order.

  In the vehicle system 10 of the embodiment, the electric vehicle 20 is provided with the display 48, but any device may be used as long as it is a device for informing information such as a speaker that emits a sound instead of the display 48.

  In the vehicle system 10 of the embodiment, it is assumed that the destination Pdt is not set in the navigation device 56 of the electric vehicle 20, but the destination Pdt may be set in the navigation device 56. In this case, in step S100 of the prediction processing routine illustrated in FIG. 3, the destination Pdt from the electric vehicle 20 is input in addition to the outside air temperature Tat, the departure date and time DT, the seating signal Ss, and the image signal Spic. In step S110, In addition to the outside air temperature Tat, the departure date / time DT, the seating signal Ss, and the image signal Spic, it may be determined whether or not the air conditioner 44 operates during parking between the current position and the destination Pdt. Then, in step S220 of the display processing routine illustrated in FIG. 4, the closest facility between the current position of the vehicle and the destination may be displayed with priority over other facilities. In step S230, the vehicle A facility with an external charging device among facilities between the current position and the destination may be displayed in preference to a facility without an external charging device.

  In the embodiment, the present invention is applied to the vehicle system 10 including the electric vehicle 20 and the data center 70, but the present invention may be applied to the electric vehicle 20.
