Description

Divisional application statement

[0001] This application is a divisional application of the Chinese invention patent application with an application date of August 1, 2022, an invention name of “Vehicle and Control Method for Vehicle” and an application number of 2022109173744. Technical Field

[0002] The present disclosure relates to a vehicle and a control method for the vehicle, and more particularly, to a vehicle configured to be capable of external charging for charging a vehicle-mounted power storage device from a charging facility provided outside the vehicle and a control method for the vehicle. Background Art

[0003] Japanese Unexamined Patent Application Publication No. 2020-114040 (JP2020-114040A) describes a vehicle configured to be capable of external charging. The vehicle is capable of operating a lid lock device and a connector lock device in synchronization with a door lock device, and a relay for switching between supply and interruption of operating power to each lock device is common (see JP2020-114040A). Summary of the invention

[0004] The charging facility may include a connector lock device that sets the connection between the charging connector of the charging facility and the inlet of the vehicle to a locked state. The charging facility equipped with the connector lock device releases the connection between the charging connector and the inlet when external charging is completed. As a result, the user can remove the charging connector from the inlet.

[0005] Here, when the user leaves the vehicle during external charging, the user generally locks the vehicle door. Afterwards, if the external charging is completed when the user returns to the vehicle, the user removes the charging connector from the inlet and closes the lid.

[0006] However, as in the case of the vehicle described in, for example, JP2020-114040A, if the lid lock device is set to the locked state in synchronization with the door lock device, the user cannot close the lid even when the user attempts to close the lid because the lid lock device is in the locked state. In order to set the lid lock device to the unlocked state, the door needs to be unlocked, so there is room for improvement from the perspective of user convenience.

[0007] The present disclosure improves user convenience in external charging using a charging facility equipped with a connector lock device.

[0008] A first aspect of the present disclosure provides a vehicle. The vehicle is configured to be capable of first external charging to charge a vehicle-mounted power storage device using power supplied from a first charging facility provided outside the vehicle. The vehicle includes a first power receiving port configured to be connectable to a first connector of the first charging facility, a first cover provided at the first power receiving port, a first cover lock device configured to switch the first cover between a locked state and an unlocked state, and a controller configured to control the first cover lock device to a locked state or an unlocked state. When the entry door of the vehicle is locked and the first cover is closed, the controller is configured to set the first cover lock device to a locked state in synchronization with the locking of the entry door. When the entry door of the vehicle is locked and the first cover is opened, the controller is configured to: set the first cover lock device to an unlocked state until the first external charging starts, set the first cover lock device to a locked state when the first external charging starts, and set the first cover lock device to an unlocked state when the first external charging is completed.

[0009] With the above configuration, even when the entry door of the vehicle is locked, but when the first cover is opened, the controller does not synchronize the first cover lock device with the locking of the entry door. The controller sets the first cover lock device to an unlocked state until the first external charging starts, so the user can close the first cover at this stage. When the first external charging starts, the controller sets the first cover lock device to a locked state, and when the first external charging is completed, the controller sets the first cover lock device to an unlocked state. With the completion of the first external charging, the first cover lock device is set to an unlocked state, so the user who disconnects the first connector from the first power receiving port can close the first cover without any additional operation. Therefore, user convenience can be improved.

[0010] In one embodiment, the first power receiving port may be configured such that the connection with the first connector is set to a locked state by a first connector lock device during the first external charging. The first connector lock device may be included in the first charging facility and may be configured to switch the connection of the first connector with the first power receiving port between a locked state and an unlocked state. The first power receiving port may be configured such that when the first external charging is completed, the connection with the first connector is set to an unlocked state by the first connector lock device.

[0011] With the above configuration, a first connector lock device that switches the connection between the first connector and the first power receiving port between a locked state and an unlocked state is provided in the first charging facility. Then, with the completion of the first external charging, the connection between the first power receiving port and the first connector is set to an unlocked state. Thus, after the completion of the first external charging, the user can disconnect the first connector from the first power receiving port without any additional operation.

[0012] In one embodiment, the vehicle may further include a relay configured to switch between supply and interruption of operating power to the first lid lock device. The controller may be configured to control the first lid lock device to a locked state or an unlocked state by controlling the relay.

[0013] With the above configuration, the controller can control the first lid lock device by controlling the relay.

[0014] In one embodiment, the vehicle may be configured to be capable of second external charging to charge the power storage device using power supplied from a second charging facility provided outside the vehicle. The vehicle may also include a second power receiving port configured to be connectable to a second connector of the second charging facility, a second cover provided at the second power receiving port, a second cover lock device configured to switch the second cover between a locked state and an unlocked state, and a second connector lock device configured to switch the connection of the second connector to the second power receiving port between a locked state and an unlocked state. The second cover lock device and the second connector lock device may be configured to receive operating power through a relay.

[0015] With the above configuration, as in the case of the first cover lock device, the second cover lock device and the second connector lock device receive operating power through the relay. Since it is not necessary to separately provide a relay for each of the plurality of lock devices, it is possible to manufacture a circuit for operating each of the plurality of lock devices at a low cost. In addition, since the plurality of relays for operating the plurality of lock devices are common, when, for example, the first external charging starts, the second cover lock device is also set to a locked state. Therefore, it is possible to reduce tampering with the second cover and the second power receiving port during the first external charging.

[0016] In one embodiment, the first external charging may be direct current charging, and the second external charging may be alternating current charging.

[0017] The second aspect of the present disclosure provides a control method for a vehicle. The vehicle is configured to be capable of first external charging to charge a vehicle-mounted power storage device using power supplied from a first charging facility provided outside the vehicle. The vehicle includes a first power receiving port configured to be connected to a first connector of the first charging facility, a first cover provided at the first power receiving port, a first cover lock device configured to switch the first cover between a locked state and an unlocked state, and a controller configured to control the first cover lock device to a locked state or an unlocked state. The control method includes, when the entry door of the vehicle is locked and the first cover is closed, setting the first cover lock device to a locked state by the controller in synchronization with the locking of the entry door, and, when the entry door of the vehicle is locked and the first cover is opened, setting the first cover lock device to an unlocked state by the controller until the first external charging starts, when the first external charging starts, setting the first cover lock device to a locked state by the controller, and when the first external charging is completed, setting the first cover lock device to an unlocked state by the controller.

[0018] According to aspects of the present disclosure, in external charging using a charging facility equipped with a connector lock device, user convenience can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The vehicle 1 is a pure electric vehicle, in which the drive wheel 30 is driven by the drive device 25 using the power stored in the power storage device 10. The vehicle 1 is configured to be able to perform alternating current (AC) charging to charge the power storage device 10 using alternating current (AC) power supplied from an alternating current (AC) charging facility 200 outside the vehicle 1, and to be able to perform direct current (DC) charging to charge the power storage device 10 using direct current (DC) power supplied from a direct current (DC) charging facility 300 outside the vehicle 1. Examples of the vehicle 1 may include a plug-in hybrid electric vehicle further equipped with an engine, and a fuel cell electric vehicle further equipped with a fuel cell as a power source in addition to the power storage device 10.

[0022] The power storage device 10 is a rechargeable power storage element. The power storage device 10 includes, for example, a secondary battery such as a lithium ion battery and a nickel metal hydride battery, or a power storage element such as a double-layer capacitor. A lithium ion secondary battery is a secondary battery using lithium as a carrier. The lithium ion secondary battery can include not only a common lithium ion secondary battery in which the electrolyte is a liquid, but also a so-called all-solid-state battery using a solid electrolyte.

[0023] The SMR 15 is a relay provided between the power storage device 10 and the electric line L1 , and is used to electrically connect the power storage device 10 to the electric line L1 or to electrically disconnect the power storage device 10 from the electric line L1 .

[0024] PCU 20 is a collection of power conversion devices for driving drive device 25 by receiving power from power storage device 10. PCU 20 includes, for example, an inverter driving a motor included in drive device 25, a converter boosting power output from power storage device 10, and the like.

[0025] The drive device 25 is a collection of devices for driving the drive wheels 30. The drive device 25 includes, for example, a motor, an engine, etc. that drives the drive wheels 30. The drive device 25 generates electric power during vehicle braking, for example, by driving the motor that drives the drive wheels 30, and outputs the generated electric power to the PCU 20.

[0026] The vehicle 1 further includes a power receiving port 40, an AC cover 42, a charger 50, and a charging relay 55 as components for performing AC charging. As in the case of an existing fuel filler port, the power receiving port 40 is made by forming a recess on the outer surface of the vehicle. The AC inlet 41 ( Figure 2 ) is provided at the power receiving port 40, and the connector 220 of the charging cable 210 connected to the AC charging facility 200 can be connected to the AC inlet 41. The AC cover 42 is a cover for the power receiving port 40, and a coupling such as a hinge is provided at the power receiving port 40 so that the AC cover 42 can be opened and closed.

[0027] A connector connection signal P1 indicating the connection state between the AC inlet 41 and the connector 220 of the charging cable 210 is output from the power receiving port 40 to a charging ECU 60 (described later). The connector connection signal P1 is activated when the connector 220 is connected to the AC inlet 41, for example.

[0028] A lid switch 81 that detects the open-closed state of the AC lid 42 is provided at the power receiving port 40. The lid switch 81 outputs a lid signal K1 indicating the open-closed state of the AC lid 42 to the charging ECU 60. The lid signal K1 is activated when the AC lid 42 is closed, for example.

[0029] A cover lock device 82 and a connector lock device 83 are further provided at the power receiving port portion 40. The cover lock device 82 is configured to switch the closed AC cover 42 between a locked state and an unlocked state. The connector lock device 83 is configured to switch the connection of the connector 220 of the charging cable 210 with the AC inlet 41 between a locked state and an unlocked state. The configurations of the power receiving port portion 40, the cover lock device 82, and the connector lock device 83 will be described in detail later.

[0030] The charger 50 converts the AC power supplied from the AC charging facility 200 into the voltage level of the power storage device 10, and outputs the power in a state where the connector 220 of the AC charging facility 200 is connected to the AC inlet 41 of the power receiving port 40. The charger 50 is configured to include, for example, a power factor correction (PFC) circuit, an inverter, an isolation transformer, a rectifier circuit, etc. The charging relay 55 is a relay for electrically connecting the charger 50 to the electric wire L2 connected to the electric wire L1, or electrically disconnecting the charger 50 from the electric wire L2.

[0031] The vehicle 1 further includes a power receiving port 45, a DC cap 47, and a charging relay 57 as components for performing DC charging. As in the case of an existing fuel filler port, the power receiving port 45 is made by forming a recess on the outer surface of the vehicle. The power receiving port 45 has a configuration that complies with the charging standard of CHAdeMO (registered trademark) or GB / T. The DC inlet 46 ( Figure 3 ) is provided at the power receiving port portion 45, and the connector 320 of the charging cable 310 connected to the DC charging facility 300 can be connected to the DC inlet 46. The DC cover 47 is a cover for the power receiving port portion 45, and a coupling such as a hinge is provided at the power receiving port portion 45 so that the DC cover 47 can be opened and closed.

[0032] A connector connection signal P2 indicating a connection state between the DC inlet 46 and the connector 320 of the charging cable 310 is output from the power receiving port 45 to the charging ECU 60 (described later). The connector connection signal P2 is activated when the connector 320 is connected to the DC inlet 46, for example.

[0033] A cover switch 86 that detects the open-closed state of the DC cover 47 is provided at the power receiving port 45. The cover switch 86 outputs a cover signal K2 indicating the open-closed state of the DC cover 47 to the charging ECU 60. The cover signal K2 is activated when the DC cover 47 is closed, for example.

[0034] A cover lock device 87 is further provided at the power receiving port portion 45. The cover lock device 87 is configured to switch the closed DC cover 47 between a locked state and an unlocked state. The configuration of the power receiving port portion 45 and the cover lock device 87 will be described in detail later.

[0035] The DC charging facility 300 according to the present embodiment complies with the charging standard of CHAdeMO or GB / T. Therefore, a connector lock device that switches the connection between the connector 320 and the DC inlet 46 between a locked state and an unlocked state is provided in the DC charging facility 300. Therefore, the power receiving port 45 according to the present embodiment does not include a connector lock device.

[0036] The vehicle 1 further includes a charging ECU 60, a body ECU 65, a check ECU 70, a door lock device 80, lock relays 100, 101, and unlock relays 102, 103. The lock relay 100 and the unlock relay 102 are accommodated in, for example, a relay box 150. The lock relay 101 and the unlock relay 103 are accommodated in, for example, a relay box 160.

[0037] Each of the charging ECU 60, the body ECU 65, and the inspection ECU 70 is configured to include a central processing unit (CPU), a memory (Random Access Memory (RAM) and Read Only Memory (ROM)), and an I / F device (none of which is shown) for inputting and outputting various signals. The CPU expands the program stored in the ROM onto the RAM and runs the program. The program stored in the ROM describes the processing performed by the CPU. The charging ECU 60, the body ECU 65, and the inspection ECU 70 are connected through an in-vehicle network (such as a Controller Area Network (CAN)), and can exchange information with each other.

[0038] In the present embodiment, an example will be described in which the control unit is divided into the charging ECU 60, the body ECU 65, and the checking ECU 70. Alternatively, any two or all of the charging ECU 60, the body ECU 65, and the checking ECU 70 may be constituted by a single ECU.

[0039] The charging ECU 60 receives a connector connection signal P1 indicating a connection state between the connector 220 of the AC charging facility 200 and the AC inlet 41 from the power receiving port 40. The charging ECU 60 receives a cover signal K1 indicating an open-closed state of the AC cover 42 from the cover switch 81. The charging ECU 60 receives a connector connection signal P2 indicating a connection state between the connector 320 of the DC charging facility 300 and the DC inlet 46 from the power receiving port 45. The charging ECU 60 receives a cover signal K2 indicating an open-closed state of the DC cover 47 from the cover switch 86.

[0040] When the connector 220 of the AC charging facility 200 is connected to the AC inlet 41 and the predetermined preparation process for performing AC charging is completed, the charging ECU 60 turns on the charging relay 55. The charging ECU 60 performs a predetermined calculation process based on signals from various sensors and information stored in the memory, and performs AC charging by controlling the charger 50 based on the calculation result. When the connector 320 of the DC charging facility 300 is connected to the DC inlet 46 and the predetermined preparation process for performing DC charging is completed, the charging ECU 60 turns on the charging relay 57. Thereby, DC charging is performed.

[0041] The check ECU 70 performs control for allowing the door lock device 80 to lock or unlock the entry door (not shown) by performing wireless communication with the mobile terminal 90 owned by the user. Specifically, when the check ECU 70 detects the door lock operation of the user during the stop of the vehicle 1, the check ECU 70 checks the ID of the mobile terminal 90. Examples of the door lock operation include an action of the user operating a door lock switch provided on the mobile terminal 90 and an action of the user touching a door lock sensor provided at the door handle.

[0042] When the ID check of the mobile terminal 90 succeeds, the check ECU 70 outputs a door lock command to the body ECU 65. When a door unlock operation by a user is detected, the check ECU 70 also checks the ID of the mobile terminal 90, and outputs a door unlock command to the body ECU 65 when the ID check succeeds.

[0043] The body ECU 65 controls the door lock device 80 based on the door lock command or the door unlock command received from the inspection ECU 70. The door lock device 80 is configured to switch the entry door in a closed state between a locked state and an unlocked state. A lock relay 100 and an unlock relay 102 are provided in the door lock device 80. The lock relay 100 is a relay that switches the supply and interruption of the operating power for operating the door lock device 80 so that the entry door is set to a locked state. The unlock relay 102 is a relay that switches the supply and interruption of the operating power for operating the door lock device 80 so that the entry door is set to an unlocked state.

[0044] When the body ECU 65 receives the door lock command from the inspection ECU 70, the body ECU 65 turns on the lock relay 100. Therefore, the door lock device 80 operates, and the entry door is set to a locked state. When the body ECU 65 receives the door unlock command from the inspection ECU 70, the body ECU 65 turns on the unlock relay 102. Therefore, the door lock device 80 operates, and the entry door is set to an unlocked state.

[0045] As will be described in detail later, a common cover lock relay 101 and a common unlock relay 103 are provided for the cover lock device 82, the connector lock device 83 and the cover lock device 87. In other words, the cover lock device 82, the connector lock device 83 and the cover lock device 87 are configured to operate synchronously with each other.

[0046] The lock relay 101 is a relay that switches the supply and interruption of the operating power for operating the cover lock device 82 so that the AC cover 42 is set to the locked state, switches the supply and interruption of the operating power for operating the connector lock device 83 so that the connection between the AC inlet 41 and the connector 220 is set to the locked state, and switches the supply and interruption of the operating power for operating the cover lock device 87 so that the DC cover 47 is set to the locked state. The unlock relay 103 is a relay that switches the supply and interruption of the operating power for operating the cover lock device 82 so that the AC cover 42 is set to the unlocked state, switches the supply and interruption of the operating power for operating the connector lock device 83 so that the connection between the AC inlet 41 and the connector 220 is set to the unlocked state, and switches the supply and interruption of the operating power for operating the cover lock device 87 so that the DC cover 47 is set to the unlocked state.

[0047] Figure 2 It is shown Figure 1 2 is a diagram showing an example of the configuration of the power receiving port portion 40 shown in FIG. Figure 2 As shown, the AC inlet 41 , the lid switch 81 , the lid lock device 82 , and the connector lock device 83 are provided at the power receiving port portion 40 .

[0048] AC inlet 41 is configured to be connectable with connector 220 of charging cable 210. When connector 220 is connected to AC inlet 41, a connector connection signal P1 to be output to charging ECU 60 is activated.

[0049] The lid switch 81 is configured to be able to detect the open-closed state of the AC lid 42. When the AC lid 42 is closed to press the lid switch 81, a lid signal K1 to be output to the charging ECU 60 is activated.

[0050] The cover lock device 82 is configured to include, for example, a retractable lock pin 82a and a drive device 82b that drives the lock pin 82a. When the cover lock device 82 extends the lock pin 82a from the position in the unlocked state, the cover lock device 82 is set to a locked state in which the AC cover 42 cannot be opened. When the cover lock device 82 retracts the lock pin 82a from the position in the locked state, the cover lock device 82 is set to an unlocked state in which the AC cover 42 can be opened. The cover lock device 82 is operable regardless of the open-closed state of the AC cover 42, and can be operated even when the AC cover 42 is open.

[0051] The connector lock device 83 is provided near the outer periphery of the AC inlet 41. The connector lock device 83 is configured to include, for example, a retractable lock pin 83a and a drive device 83b that drives the lock pin 83a. When the connector lock device 83 extends the lock pin 83a from the position in the unlocked state, the connector lock device 83 is set to a locked state in which the connector 220 of the charging cable 210 connected to the AC inlet 41 cannot be removed from the AC inlet 41. When the connector lock device 83 retracts the lock pin 83a from the position in the locked state, the connector lock device 83 is set to an unlocked state in which the connector 220 can be removed from the AC inlet 41. The connector lock device 83 is operable regardless of whether the connector 220 is connected to the AC inlet 41, and can be operated even when the connector 220 is not connected to the AC inlet 41.

[0052] Figure 3 It is shown Figure 1 2 is a diagram showing an example of the configuration of the power receiving port portion 45 shown in FIG. Figure 3 As shown, the DC inlet 46 , the lid switch 86 , and the lid lock device 82 are provided at the power receiving port portion 45 .

[0053] The DC inlet 46 is configured to be connectable with the connector 320 of the charging cable 310. When the connector 320 is connected to the DC inlet 46, a connector connection signal P2 to be output to the charging ECU 60 is activated.

[0054] The cover switch 86 is configured to be able to detect the open-closed state of the DC cover 47. When the DC cover 47 is closed to press the cover switch 86, a cover signal K2 to be output to the charging ECU 60 is activated.

[0055] The cover lock device 87 is configured to include, for example, a retractable lock pin 87a and a drive device 87b that drives the lock pin 82a. When the cover lock device 87 extends the lock pin 87a from the position in the unlocked state, the cover lock device 87 is set to a locked state in which the DC cover 47 cannot be opened. When the cover lock device 87 retracts the lock pin 87a from the position in the locked state, the cover lock device 87 is set to an unlocked state in which the DC cover 47 can be opened. Regardless of the open-closed state of the DC cover 47, the cover lock device 87 is operable and can operate even when the DC cover 47 is open.

[0056] Figure 4 1 is a diagram showing an example of a configuration of a circuit for operating the lid lock device 82, the connector lock device 83, and the lid lock device 87. In the vehicle 1 according to the present embodiment, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are connected to the same relay box 160 and receive operating power through the relay box 160.

[0057] like Figure 4As shown, the locking relay 101 includes a contact 101a and a coil 101b. When the coil 101b is energized, the contact 101a operates to connect the wire L4 to the power supply node 510. When the coil 101b is de-energized, the contact 101a operates to connect the wire L4 to the vehicle body ground 520. The coil 101b is connected to the vehicle body ECU 65 via a signal line S1. The coil 101b is switched between a power-on state and a power-off state by the vehicle body ECU 65. Hereinafter, the state in which the wire L4 is connected to the power supply node 510 is referred to as the locking relay 101 being turned on, and the state in which the wire L4 is connected to the vehicle body ground 520 is referred to as the locking relay 101 being turned off.

[0058] The unlocking relay 103 includes a contact 103a and a coil 103b. When the coil 103b is energized, the contact 103a operates to connect the wire L5 to the power node 510. When the coil 103b is de-energized, the contact 103a operates to connect the wire L5 to the vehicle body ground 520. The coil 103b is connected to the vehicle body ECU 65 via a signal line S2. The coil 103b switches between the energized state and the de-energized state due to the vehicle body ECU 65. Hereinafter, the state in which the wire L5 is connected to the power node 510 is referred to as the unlocking relay 103 being turned on, and the state in which the wire L5 is connected to the vehicle body ground 520 is referred to as the unlocking relay 103 being turned off.

[0059] The cover lock device 82 , the connector lock device 83 , and the cover lock device 87 are connected in parallel with each other between the electric wire L4 and the electric wire L5 .

[0060] The cover lock device 82 includes the lock pin 82a and the drive device 82b as described above. The drive device 82b includes, for example, a motor, and is connected between the wire L4 and the wire L5. The motor included in the drive device 82b rotates forward when the current (locking current) flows from the wire L4 to the wire L5 through the motor, and rotates reversely when the current (unlocking current) flows from the wire L5 to the wire L4 through the motor. When the motor rotates forward, the drive device 82b extends the lock pin 82a to convert the cover lock device 82 from the unlocked state to the locked state. When the motor rotates reversely, the drive device 82b retracts the lock pin 82a to convert the cover lock device 82 from the locked state to the unlocked state.

[0061] The connector lock device 83 includes the locking pin 83a and the driving device 83b as described above. The driving device 83b includes, for example, a motor and is connected between the wire L4 and the wire L5. The motor included in the driving device 83b rotates forward when the current (locking current) flows from the wire L4 to the wire L5 through the motor, and rotates reversely when the current (unlocking current) flows from the wire L5 to the wire L4 through the motor. When the motor rotates forward, the driving device 83b extends the locking pin 83a to convert the connector lock device 83 from the unlocked state to the locked state. When the motor rotates reversely, the driving device 83b retracts the locking pin 83a to convert the connector lock device 83 from the locked state to the unlocked state.

[0062] The connector lock device 83 may further include a lock detection switch 83c that detects the conversion of the connector lock device 83 to the locked state. The lock detection switch 83c is connected to the body ECU 65 via a signal line S3. The lock detection switch 83c is pushed by, for example, a lock pin 83a that is converted to a position of the locked state and is set to an on state. When, for example, the lock pin 83a is converted from the position of the locked state to the position of the unlocked state, the lock detection switch 83c is no longer pushed by the lock pin 83a and is set to an off state. The body ECU 65 detects the state of the connector lock device 83 based on, for example, the voltage level of the signal line S3.

[0063] The cover lock device 87 includes the lock pin 87a and the drive device 87b as described above. The drive device 87b includes, for example, a motor and is connected between the wire L4 and the wire L5. The motor included in the drive device 87b rotates forward when the current (locking current) flows from the wire L4 to the wire L5 through the motor, and rotates reversely when the current (unlocking current) flows from the wire L5 to the wire L4 through the motor. When the motor rotates forward, the drive device 87b extends the lock pin 87a, so that the cover lock device 87 is switched from the unlocked state to the locked state. When the motor rotates reversely, the drive device 87b retracts the lock pin 87a, and the cover lock device 87 is switched from the locked state to the unlocked state.

[0064] In the vehicle 1 according to the present embodiment, for the locking operation, the lid lock device 82, the connector lock device 83 and the lid lock device 87 receive operating power from the same lock relay 101. For the unlocking operation, the lid lock device 82, the connector lock device 83 and the lid lock device 87 receive operating power from the same unlocking relay 103. Synchronization and desynchronization with the door lock command or door unlock command

[0065] In the vehicle 1 according to the present embodiment, the body ECU 65 determines whether to synchronize the control of the relay box 160 with the door lock command and the door unlock command based on the open-close state of the DC cover 47. The body ECU 65 detects the open-close state of the DC cover 47 based on the cover signal K2 received via the charging ECU 60.

[0066] When the DC cover 47 is in the closed state, the body ECU 65 controls the relay box 160 (lock relay 101 and unlock relay 103) in synchronization with the door lock command or the door unlock command. When the body ECU 65 receives the door lock command in the state where the DC cover 47 is closed (closed state), the body ECU 65 turns on the lock relay 101 in addition to the lock relay 100. Specifically, the body ECU 65 turns on the lock relay 100 and turns off the unlock relay 102 in response to the door lock command, and turns on the lock relay 101 and turns off the unlock relay 103. Therefore, the door lock device 80 is set to the locked state, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are also set to the locked state.

[0067] When the body ECU 65 receives the door unlock command in the state where the DC cover 47 is closed (closed state), the body ECU 65 turns on the unlock relay 103 in addition to the unlock relay 102. Specifically, the body ECU 65 turns off the lock relay 100 and turns on the unlock relay 102 in response to the door unlock command, and turns off the lock relay 101 and turns on the unlock relay 103. Therefore, the door lock device 80 is set to the unlock state, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are also set to the unlock state.

[0068] When the DC cover 47 is in the open state, the body ECU 65 does not synchronize the control of the relay box 160 with the door lock command. When the body ECU 65 receives the door lock command in the state where the DC cover 47 is opened (on state), the body ECU 65 turns on the lock relay 100 and turns off the unlock relay 102 in response to the door lock command, and keeps the lock relay 101 in the off state and the unlock relay 103 in the off state until the start of DC charging. Then, when DC charging is started, the body ECU 65 turns on the lock relay 101 and turns off the unlock relay 103 until the DC charging is completed (i.e., during DC charging). Thereafter, when the DC charging is completed, the body ECU 65 turns off the lock relay 101 and turns on the unlock relay 103. Therefore, the door lock device 80 is set to the locked state in response to the door lock command, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are set to the locked state only during DC charging. By setting the lid lock device 82 , the connector lock device 83 , and the lid lock device 87 to the locked state during DC charging, tampering with the AC cover 42 and the power receiving port 40 during DC charging is reduced.

[0069] When the conversion of the lid lock device 82, the connector lock device 83 and the lid lock device 87 to the locked state or the unlocked state is completed, the body ECU 65 disconnects the lock relay 101 and the unlock relay 103, and maintains the locked state position or the unlocked state position of each of the lock pins 82a, 83a, 87a of the lid lock device 82, the connector lock device 83 and the lid lock device 87. Timing diagram

[0070] Figure 5 is a timing diagram of the comparative example. According to the above configuration, it is possible to avoid a situation such as the case of the comparative example described below. Assume that in the vehicle according to the comparative example, the locking relays of the door lock device 80, the lid lock device 82, the connector lock device 83 and the lid lock device 87 are common, and the unlocking relays of the door lock device 80, the lid lock device 82, the connector lock device 83 and the lid lock device 87 are common. In the vehicle according to the comparative example, the locking relay and the unlocking relay are controlled in response to the door locking command and the door unlocking command. In other words, in the vehicle according to the comparative example, the door lock device 80, the lid lock device 82, the connector lock device 83 and the lid lock device 87 are controlled to be constantly synchronized with each other.

[0071] like Figure 5 As shown, Figure 5 User operations related to DC charging (charging operations), the state of the cover lock device 87 , the open-closed state of the DC cover 47 , and a lock image of the DC cover 47 are shown.

[0072] First, assume that the vehicle stops with the DC cover 47 closed. At time t1, the DC cover 47 is opened by the user. Then, the user connects the connector 420 of the DC charging facility 300 to the DC inlet 46, and at time t2, a door locking operation for locking the entry door is performed. As a result of the door locking operation, the inspection ECU 70 sends a door locking command to the body ECU 65. In response to the door locking command, the body ECU 65 converts not only the door lock device 80 but also the lid lock device 82, the connector lock device 83 and the lid lock device 87 to a locked state. Therefore, the lock pin 87a of the lid lock device 87 extends, and the DC cover 47 cannot be closed due to the extended lock pin 87a.

[0073] At time t3, the user performs a start operation for starting DC charging. As a result, the connector lock device of DC charging facility 300 operates, and the connection between DC inlet 46 and connector 320 is set to a locked state.

[0074] At time t4 , when DC charging is completed, the connection between the DC inlet 46 and the connector 320 is set to the unlocked state, and the connector 320 is detached from the DC inlet 46 .

[0075] At time t5, the user attempts to close the DC cover 47. However, since the cover lock device 87 is in the locked state, the operation of closing the DC cover 47 is blocked by the lock pin 87a, and the user cannot close the DC cover 47. In order to set the cover lock device 87 to the unlocked state, an operation for unlocking the entry door is required. An additional operation is required to close the DC cover 47, which may impair user convenience.

[0076] Figure 6 is a timing diagram of this embodiment. Figure 5 Same situation, Figure 6 User operations related to DC charging (charging operations), the state of the cover lock device 87 , the open-closed state of the DC cover 47 , and a lock image of the DC cover 47 are shown.

[0077] First, it is assumed that the vehicle 1 stops with the DC cover 47 closed. At time t10, the DC cover 47 is opened by the user. Then, the user connects the connector 420 of the DC charging facility 300 to the DC inlet 46, and at time t11, performs a door locking operation for locking the entry door. As a result of the door locking operation, the check ECU 70 sends a door locking command to the body ECU 65. The body ECU 65 converts the door lock device to a locked state in response to the door locking command. However, the body ECU 65 keeps the lid lock device 82, the connector lock device 83 and the lid lock device 87 in an unlocked state. In other words, the lid lock device 87 is not converted to a locked state by the door locking operation. Therefore, at this stage, the user is able to close the DC cover 47.

[0078] At time t12, the user performs a start operation for starting DC charging. Therefore, the body ECU 65 switches the lid lock device 82, the connector lock device 83, and the lid lock device 87 to a locked state. In addition, the connector lock device (not shown) of the DC charging facility 300 operates, and the connection between the DC inlet 46 and the connector 320 is set to a locked state. During DC charging, the lid lock device 82 is also set to a locked state. As a result, the AC cover 42 cannot be opened during DC charging, thereby reducing tampering with the AC cover 42 and the power receiving port 40 during DC charging.

[0079] At time t13, DC charging is completed. As a result of the completion of DC charging, the connector lock device (not shown) of DC charging facility 300 operates, and the connection between DC inlet 46 and connector 320 is set to an unlocked state. Then, the user disconnects connector 320 from DC inlet 46.

[0080] As a result of the completion of DC charging, the body ECU 65 switches the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the unlocked state. Thus, the user who disconnects the connector 320 from the DC inlet 46 at time t14 can close the DC lid 47. flow chart

[0081] Figure 7 6 is a flowchart showing an example of the procedure of the processing executed in response to the door lock command. The processing of this flowchart is started by the body ECU 65 when the body ECU 65 receives the door lock command from the inspection ECU 70. When implemented by software processing on the body ECU 65, the following will be described. Figure 7 The steps of the flowchart shown (hereinafter, the steps are abbreviated as “S”) are shown in FIG. 6 . Alternatively, one, some, or all of these steps may be realized by hardware (electronic circuit) created in the body ECU 65 .

[0082] In S1, the body ECU 65 determines whether the DC cover 47 is open based on the detection result of the cover switch 86. The body ECU 65 may receive the cover signal K2 via the charging ECU 60 and determine whether the DC cover 47 is open based on the cover signal K2, or may determine whether the DC cover 47 is open based on the open-closed state of the DC cover 47 determined by the charging ECU 60 that receives the cover signal K2 from the cover switch 86. When the body ECU 65 determines that the DC cover 47 is open (Yes in S1), the process proceeds to S3. When the body ECU 65 determines that the DC cover 47 is not open (No in S1), the process proceeds to S13.

[0083] In S3, the body ECU 65 keeps the lock relay 101 and the unlock relay 103 in the OFF state. In other words, the body ECU 65 keeps the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the unlocked state. The body ECU 65 turns on the lock relay 100 and turns off the unlock relay 102 in response to the door lock command to set the door lock device 80 to the locked state and lock the entry door.

[0084] In S5, the body ECU 65 determines whether DC charging has started. Whether DC charging has started is transmitted from the charging ECU 60 to the body ECU 65. For example, when the user presses a charging start button provided at the DC charging facility 300, communication is established between the DC charging facility 300 and the charging ECU 60. The body ECU 65 can detect the start of DC charging as a result of the established communication transmitted from the charging ECU 60 to the body ECU 65. When the body ECU 65 determines that DC charging has not started (No in S5), the body ECU 65 waits for the start of DC charging. Before starting DC charging, the user can close the DC cover 47. When the body ECU 65 determines that DC charging has started (Yes in S5), the process proceeds to S7.

[0085] In S7, the body ECU 65 turns on the lock relay 101 and turns off the unlock relay 103 to set the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state. As a result, during DC charging, the lid lock device 82 of the AC cover 42 is also set to the locked state, so that the AC cover 42 cannot be opened. As a result, during DC charging, tampering with the AC cover 42 and the power receiving port 40 can be reduced.

[0086] In S9, the body ECU 65 determines whether the DC charging is completed. The DC charging stops when a condition is satisfied. The condition may be, for example, at least any one of a condition that the power storage device 10 is fully charged, a condition that the state of charge (SOC) of the power storage device 10 has reached a set SOC, a condition that a set charging time has passed, and a condition that a charging stop button provided in the DC charging facility 300 is pressed. The body ECU 65 waits for the DC charging to be completed (No in S9). When the DC charging is completed (Yes in S9), the body ECU 65 advances the process to S11.

[0087] In S11, the body ECU 65 turns off the lock relay 101 and turns on the unlock relay 103 to set the lid lock device 82, the connector lock device 83 and the lid lock device 87 to the unlocked state. Therefore, the user disconnects the connector 320 from the DC inlet 46 and can close the DC cover 47.

[0088] In S13, the body ECU 65 turns on the lock relay 101 and turns off the unlock relay 103 to set the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state. When the DC cover 47 is not opened, it is assumed that DC charging is not performed. The body ECU 80 sets the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state in synchronization with the door lock command. The body ECU 65 turns on the lock relay 100 and turns off the unlock relay 102 in response to the door lock command to set the door lock device 80 to the locked state.

[0089] In S15, the body ECU 65 determines whether a door unlock command is received from the inspection ECU 70. When the body ECU 65 determines that the door unlock command is not received (No in S15), the body ECU 65 waits for reception of the door unlock command. When the body ECU 65 determines that the door unlock command is received (Yes in S15), the process proceeds to S17.

[0090] In S17, the body ECU 65 turns off the lock relay 101 and turns on the unlock relay 103 to set the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the unlock state. The body ECU 65 turns off the lock relay 100 and turns on the unlock relay 102 in response to the door unlock command to set the door lock device 80 to the unlock state.

[0091] As described above, in the vehicle 1 according to the present embodiment, when the DC cover 47 is in the closed state, the control of the relay box 160 (locking relay 101 and unlocking relay 103) is synchronized with the door locking command, and when the DC cover 47 is in the open state, the control of the relay box 160 (locking relay 101 and unlocking relay 103) is not synchronized with the door locking command. When the DC cover 47 is in the closed state, it is assumed that DC charging is not performed. In this case, by collectively switching the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state in response to the door locking operation, user convenience can be improved.

[0092] On the other hand, when the DC cover 47 is in the open state, it is assumed that DC charging is performed. In this case, when the control of the relay box 160 is synchronized with the door lock command, an additional operation for closing the DC cover 47 (operation for unlocking the entry door) is required after the DC charging is completed, thereby reducing user convenience. Therefore, by not synchronizing the control of the relay box 160 with the door lock command, it is possible to suppress reduction in user convenience.

[0093] In the vehicle 1 according to the present embodiment, when the DC cover 47 is in the open state, the cover lock device 87 is set to the unlocked state until the DC charging starts, the cover lock device 87 is set to the locked state during the DC charging, and when the DC charging is completed, the cover lock device 87 is set to the unlocked state. Since the cover lock device 87 is set to the unlocked state when the DC charging is completed, the user can close the DC cover 47 without any additional operation.

[0094] During DC charging, the cover lock device 82 is also set to the locked state. In other words, during DC charging, since the AC cover 42 cannot be opened, tampering with the AC cover 42 and the power receiving port 40 during DC charging can be reduced.

[0095] In the vehicle 1 according to the present embodiment, the relay that switches between the supply and interruption of the operating power to each of the lid lock device 82, the connector lock device 83, and the lid lock device 87 is common. Therefore, it is not necessary to separately provide a relay that switches between the supply and interruption of the operating power to each of the lid lock device 82, the connector lock device 83, and the lid lock device 87, so the circuit can be manufactured at a low cost. Modifications

[0096] In the embodiment, it has been described that each of the cover lock device 82, the connector lock device 83, and the cover lock device 87 includes a lock pin and a drive device as an example of its mechanism.
