CN-122008917-A - Vehicle with a vehicle body having a vehicle body support

Abstract

The present invention relates to a vehicle. When the charging connector is connected to the socket, the charging control ECU brings the connector into a locked state by the locking device. When the lock release mechanism is operated to unlock the lock device, the charge control ECU sets the flag to 1. In the failure detection process, if the flag is set to 1, the charge control ECU outputs an unlock instruction after outputting the lock instruction. Further, when the lock device is in the unlock state, no failure is diagnosed, and when the lock device is not in the unlock state, an unlock failure is diagnosed.

Claims (5)

1. 1. A vehicle, wherein, Comprises a socket capable of being connected with a charging connector; A locking device for switching a locking state in which the charging connector cannot be pulled out from the socket to an unlocking state in which the charging connector can be pulled out from the socket, and The control device is used for controlling the control device, The locking device includes an actuator and a lock release mechanism, The actuator is operated so as to switch from the unlock state to the lock state in response to a lock instruction from the control device and to switch from the lock state to the unlock state in response to a lock instruction from the control device, The lock release mechanism is switched from the lock state to the unlock state irrespective of the operation of the actuator, The control device detects that the lock release mechanism is operated to switch from the lock state to the unlock state, outputs the unlock instruction after the lock instruction is output in a state in which the charging connector is pulled out from the socket, and diagnoses that the lock device is in an unlock failure when the lock device is not in the unlock state after the unlock instruction is output.
2. 2. The vehicle according to claim 1, wherein, The locking means comprises a locking pin driven by the actuator, The control device detects the locked state and the unlocked state based on the position of the locking pin.
3. 3. The vehicle according to claim 2, wherein, The control device detects that the lock is switched from the locked state to the unlocked state by an operation of the lock release mechanism when the position of the lock pin is changed from the locked state to the unlocked state in a state where the unlock instruction is not output.
4. 4. The vehicle according to claim 1 or 2, wherein, The control device diagnoses the unlocking failure while the vehicle is running.
5. 5. The vehicle according to claim 1 or 2, wherein, And the control device notifies the unlocking fault when the control device is diagnosed to be in the unlocking fault.

Description

Vehicle with a vehicle body having a vehicle body support Technical Field The present disclosure relates to a vehicle. Background Japanese patent application laid-open No. 2021-150980 discloses a vehicle charging device that determines a failure of a lock actuator that locks a power source side connector (charging connector) connected to a charging port (socket) of a vehicle. When the vehicle speed is equal to or higher than a predetermined speed, the charging control device of japanese patent application laid-open No. 2021-150980 performs an operation check of the lock actuator. In the operation check, an operation command to the lock pin is transmitted to the lock actuator, and a failure of the lock actuator is determined based on whether or not the position of the lock pin detected by the position detection sensor is at the position of the operation command. In japanese patent application laid-open No. 2021-150980, the control device outputs a lock instruction and an unlock instruction to the lock actuator. Further, after the lock instruction and the unlock instruction, a failure of the lock actuator is determined based on the position of the lock pin. Therefore, in the case where the unlock instruction is not output due to some abnormality, the unlock failure of the lock actuator cannot be determined. Disclosure of Invention The present disclosure aims to diagnose an unlocking failure even without outputting an unlocking instruction. The vehicle of the present disclosure includes: a socket connectable to a charging connector; a locking device for switching a locking state in which the charging connector cannot be pulled out from the socket to an unlocking state in which the charging connector can be pulled out from the socket, and And a control device. The locking device includes an actuator and a lock release mechanism. The actuator is operated to switch from the unlock state to the lock state in response to a lock instruction from the control device, and to switch from the lock state to the unlock state in response to the lock instruction from the control device. The lock release mechanism is switched from the locked state to the unlocked state irrespective of the operation of the actuator. When the lock release mechanism is operated to detect a switch from the locked state to the unlocked state, the control device outputs the unlock instruction after outputting the lock instruction in a state in which the charging connector is pulled out from the outlet, and diagnoses an unlock failure when the lock device is not in the unlocked state after outputting the unlock instruction. According to this configuration, the actuator receives a lock instruction from the control device, and switches the lock device from the unlock state to the lock state. The actuator receives an unlocking instruction of the control device and switches the locking device from the locking state to the unlocking state. When the lock release mechanism is operated, the lock device is switched from the locked state to the unlocked state regardless of the operation of the actuator. When the control device detects that the lock release mechanism is switched from the locked state to the unlocked state, the control device outputs the lock instruction and then outputs the unlock instruction in a state in which the charging connector is pulled out from the outlet. After the output of the unlock command, the control device diagnoses that the lock device is in the unlock failure when the lock device is not in the unlock state. The possibility that the switching from the locked state to the unlocked state by the lock release mechanism is performed when the unlock command is not output from the control device and the unlock state is not performed is high. Or in the case where the actuator does not move from the locked state to the unlocked state, the possibility of the actuator moving to the unlocked state is high. When the unlocking mechanism is operated to detect a switch from the locked state to the unlocked state, the control device outputs an unlock instruction after outputting the lock instruction in a state in which the charging connector is pulled out from the outlet. After the unlocking instruction, the locking device is in a locked state when the locking device is not in an unlocked state. Therefore, a failure in which the control device does not output an unlock command or a failure in which the actuator does not operate from the locked state to the unlocked state can be diagnosed. Therefore, even in the case where the unlock instruction is not output, the unlock failure can be diagnosed. Preferably, the locking means may also include a locking pin driven by the actuator, and the control means detects the locked state and the unlocked state based on the position of the locking pin. According to this structure, by detecting the position of the lock pin, the locked state and the unlocked state can be detected relatively easily. Preferabl
