The ECU 100 switches between fixing (locking) / unlocking (unlocking) the charging connector 410 and the inlet 22 by operating a locking mechanism (not shown) in response to a signal from the cable lock switch 23.

  The inlet 22 and the cable lock switch 23 are normally covered with the charging lid 2. When the charging lid 2 is opened by a user operation, the user can connect the charging connector 410 to the inlet 22 or operate the cable lock switch 23.

  The charger 20 converts external power (AC power) received by the inlet 22 into power (DC power) that can charge the battery 10 and outputs the power to the battery 10.

  The battery 10 is a secondary battery that stores electric power to be supplied to a travel motor (not shown). Note that a large-capacity capacitor may be employed instead of the battery 10.

  The storage unit 40 is provided in a luggage space behind the vehicle interior and has a space in which the charging cable 400 that is not connected to both the external power supply device 500 and the inlet 22 can be stored. After the charging is completed, the user can remove the charging cable 400 from the external power supply device 500 and the inlet 22 and store it in the storage unit 40.

  Each of the plurality of door portions (the left front door 4L, the right front door 4R, the left rear door 5L, the right rear door 5R, and the back door 3) is provided between the vehicle exterior and the vehicle interior.

  The left front door 4L, the right front door 4R, the left rear door 5L, and the right rear door 5R are opened and closed by a user's manual operation when the user gets on and off the vehicle 1 mainly.

  The back door 3 is opened and closed mainly when a user loads or unloads luggage in the luggage space. The opening / closing method of the back door 3 according to the present embodiment is a so-called flip-up type that is opened by flipping the back door 3 upward (refer to a one-dot chain line). The back door 3 may be opened and closed by a method different from the flip-up method, for example, a lateral opening method.

  The back door 3 according to the present embodiment is a back door (so-called power back door) that can be opened and closed by a user's manual operation and that can be automatically opened and closed by the back door operating device 30.

  The back door operating device 30 is configured to automatically operate (open / close) the back door 3 by driving a motor provided therein using electric power from an auxiliary battery (not shown). The back door operating device 30 is controlled by a control signal from the ECU 100.

  The open / close detection sensor 31 detects whether the back door 3 is open or closed, and outputs the detection result to the ECU 100.

  The navigation device 50 detects current position information of the vehicle 1 using GPS (Global Positioning System) and outputs the detected information to the ECU 100. Moreover, the navigation apparatus 50 can memorize | store the information (for example, home position information) registered by the user.

When charging connector 410 is connected to inlet 22, a signal indicating that charging connector 410 is connected to inlet 22 is output from inlet 22 to ECU 100. Further, when the user presses the PISW 411 while the charging connector 410 is connected to the inlet 22, a signal indicating that the user is pressing the PISW 411 is output from the inlet 22 to the ECU 100, and the charging connector 410 is connected from the inlet 22. It will be in a removable state.

<Automatic opening of back door>
As described above, the vehicle 1 is provided with the storage unit 40 for storing the charging cable 400 in the luggage space in the vehicle interior. Therefore, in order to store the charging cable 400 in the storage unit 40 after completion of charging, it is necessary to open the back door 3 that is the door closest to the storage unit 40. However, there is a concern that the user feels troublesome to perform the operation of opening the back door 3.

  Therefore, the ECU 100 according to the present embodiment controls the back door operating device 30 to open the back door 3 when the charging connector 410 is changed from the state connected to the inlet 22 to the state not connected. Thereby, the back door 3 closest to the storage unit 40 is automatically opened only by the user performing an operation of removing the charging connector 410 from the inlet 22 after the charging is completed. Therefore, the user can store the charging cable 400 in the storage unit 40 without performing an operation of opening the back door 3. As a result, it is possible to reduce the trouble of the user when the charging cable 400 is stored in the storage unit 40 in the vehicle interior.

  FIG. 2 is a flowchart showing a processing procedure when the ECU 100 performs the automatic opening operation of the back door 3. This flowchart is repeatedly executed at a predetermined cycle.

  In S10, ECU 100 determines whether or not charging connector 410 has changed from being connected to inlet 22 to being not connected based on a signal from inlet 22 (whether charging connector 410 has been removed from inlet 22 or not). Or not).

  If charging connector 410 has not changed from the state connected to inlet 22 to the state where it is not connected (NO in S10), ECU 100 ends the process.

  When charging connector 410 changes from the state connected to inlet 22 to the state where it is not connected (YES in S10), ECU 100 performs an automatic opening operation of back door 3 in S11 and S12. Specifically, the ECU 100 determines whether or not the back door 3 is in a closed state based on the output of the open / close detection sensor 31 in S11. If back door 3 is in the closed state (YES in S11), ECU 100 controls back door operating device 30 to automatically open back door 3 in S12.

  As described above, the ECU 100 according to the present embodiment controls the back door operating device 30 to open the back door 3 when the charging connector 410 is changed from the state connected to the inlet 22 to the state not connected. . Thereby, the back door 3 closest to the storage unit 40 is automatically opened only by the user performing an operation of removing the charging connector 410 from the inlet 22 after the charging is completed. Therefore, the user can store the charging cable 400 in the storage unit 40 without performing an operation of opening the back door 3. As a result, it is possible to reduce the trouble of the user when the charging cable 400 is stored in the storage unit 40 in the vehicle interior.

<Modification>
The above-described embodiment can be modified as follows, for example.

  (1) In the above-described embodiment, the condition for performing the automatic opening operation of the back door 3 is changed from the state where the charging connector 410 is connected to the inlet 22 to the state where it is not connected (hereinafter referred to as “charging cable”). It was also called “removal condition”. However, the following conditions (1A) to (1C) may be further added as conditions for performing the automatic opening operation of the back door 3 in addition to the above charging cable removal conditions.

  (1A) A condition that the charging cable 400 is stored in the storage unit 40 may be added.

  FIG. 3 is a flowchart showing a processing procedure of the ECU 100 according to this modification. Note that among the steps shown in FIG. 3, steps having the same numbers as the steps shown in FIG. 2 described above have already been described, and thus detailed description thereof will not be repeated here.

  When charging connector 410 changes from the state connected to inlet 22 to the state where it is not connected (YES in S10), ECU 100 determines whether or not charging cable 400 is stored in storage unit 40 in S20. Determine. This determination can be realized, for example, by providing a weight sensor in the storage unit 40. That is, the ECU 100 determines that the charging cable 400 is stored in the storage unit 40 when the weight sensor provided in the storage unit 40 measures the weight corresponding to the charging cable 400.

  When charging cable 400 is not already stored in storage unit 40 (NO in S20), there is a possibility that the charging cable removed from inlet 22 is a vehicle-mounted (personal) charging cable 400 owned by the user. Since it is high, ECU 300 performs the above-described automatic opening operation of back door 3 in S11 and S12.

  On the other hand, when charging cable 400 is already stored in storage unit 40 (YES in S20), the charging cable removed from inlet 22 is not installed on in-vehicle charging cable 400 but is installed at a charging station, for example. Since there is a high possibility that the charging cable is for public use, the ECU 300 terminates the process without performing the automatic opening operation of the back door 3. Thereby, it is possible to prevent the back door 3 from being automatically opened unnecessarily until it is not necessary to store the charging cable 400 in the storage unit 40.

(1B) A condition that the current position of the vehicle 1 is around the home may be added.
FIG. 4 is a flowchart showing a processing procedure of the ECU 100 according to this modification. Of the steps shown in FIG. 4, the steps given the same numbers as the steps shown in FIG. 2 described above have already been described, and detailed description thereof will not be repeated here.

  When charging connector 410 changes from the state connected to inlet 22 to the state not connected (YES in S10), ECU 100 determines the current position of vehicle 1 based on the information from navigation device 50 in S30. It is determined whether or not is around the user's home.

  When the current position of vehicle 1 is around the home (YES in S30), ECU 300 is likely to be the in-vehicle charging cable 400 instead of the public charging cable because the charging cable removed from the inlet 22 is not the public charging cable. In S11 and S12, the above-described back door 3 is automatically opened.

  On the other hand, if the current position of vehicle 1 is not around the home (NO in S30), ECU 300 may be a charging cable for public use instead of in-vehicle charging cable 400 because the charging cable removed from inlet 22 may be a public charging cable. Finishes the process without automatically opening the back door 3. Thereby, it is possible to prevent the back door 3 from being automatically opened unnecessarily until it is not necessary to store the charging cable 400 in the storage unit 40.

  A place where the user desires the automatic opening operation of the back door 3 at a place other than his / her home is registered in the navigation device 50 in advance, and the back door 3 is located when the current position of the vehicle 1 is around the registered place. An automatic opening operation may be performed.

  (1C) A condition that there is a history of opening / closing operation of the back door 3 before charging may be added. That is, the ECU 100 stores the opening / closing operation history of the back door 3 before charging, the charging cable removal condition is satisfied, and the condition that the opening / closing operation of the back door 3 is performed before charging is satisfied. In this case, the charging cable removed from the inlet 22 may be estimated to be the in-vehicle charging cable 400, and the back door 3 may be automatically opened.

  (2) Further, instead of the charging cable removal condition, the automatic opening operation of the back door 3 may be performed on condition that the user keeps pressing the PISW 411 for a predetermined time or more. Further, instead of or in addition to the charging cable removal condition, the automatic opening operation of the back door 3 may be performed on the condition that the user keeps pressing the cable lock switch 23 for a predetermined time or more.

  (3) In the above-described embodiment, the case where the storage unit 40 is provided in the luggage space in the passenger compartment is illustrated. However, in a vehicle having a trunk room independent from the passenger compartment, the storage unit 40 is placed in the trunk room. You may make it provide. In this case, the object of the automatic opening operation may be a trunk door.

  In addition, the above-described embodiments and modifications thereof may be combined as appropriate within a range where no technical contradiction occurs.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
