CN-122008916-A - Vehicle with a vehicle body having a vehicle body support

Abstract

If 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 locking device is in the unlocked state, the charging connector can be pulled out from the socket. When the vehicle speed is equal to or greater than a predetermined value and the lock device is in a locked state, the charge control ECU outputs an unlock command to the lock device. In the case where the lock device is not in the unlock state after the unlock instruction is output, the charge control ECU diagnoses that it is a failure of the lock device.

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 (outlet) 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, when the charging connector is connected to the socket, the temporary failure flag is turned on based on the position of the locking pin. When the temporary failure flag is turned on, if the vehicle speed is equal to or higher than a predetermined vehicle speed, the lock actuator is operated a plurality of times to determine a failure of the lock actuator. Therefore, when the temporary failure flag is not turned on at the time of connecting the charging connector to the outlet, the lock failure of the actuator cannot be determined. Disclosure of Invention The present disclosure aims to diagnose a failure of a locking device even in the case where there is no sign of the failure of the locking device when a charging connector is connected to a socket. The vehicle of the present disclosure includes: a socket connectable to a charging connector; a locking device for switching between a locked state in which the charging connector cannot be pulled out from the socket and an unlocked state in which the charging connector can be pulled out from the socket; A detection device for detecting the locking state and the unlocking state, and And a control device. The locking device operates to the locked state when receiving a locking instruction from the control device, and operates to the unlocked state when receiving an unlocking instruction from the control device. The control device is configured to: when the detection device detects the locking state during the running of the vehicle, an unlocking instruction is output, When the detection device does not detect the unlock state after outputting the unlock instruction, a failure of the lock device is diagnosed. According to this configuration, the lock device operates in the locked state when receiving the lock instruction from the control device, and operates in the unlocked state when receiving the unlock instruction from the control device. When the detection device detects a locked state during running of the vehicle, the control device outputs an unlock command. After outputting the unlock instruction, the control device diagnoses a failure of the lock device if the detection device does not detect the unlock state. During running of the vehicle, the charging connector is pulled out from the socket. In this state, when the lock state is detected and the unlock instruction is output, the lock device is switched from the lock state to the unlock state, and the detection device detects the unlock state. When the lock device is not switched to the unlock state even if the unlock instruction is received and the unlock state cannot be detected, it can be diagnosed that the lock failure has occurred. Therefore, even in the case where there is no sign of a failure when the charging connector is connected to the outlet, the failure of the locking device can be diagnosed. The control device of the vehicle may be configured to output an unlock command when the detection device detects the locked state in a state in which the charging connector is removed from the outlet, and to diagnose that the vehicle is a failure of the locking device when the detection device does not detect the unlocked state after the unlock command is output. According to this configuration, when the lock state is detected in a state in which the charging connector is pulled out from the outlet, the lock device is switched from the lock state to the unlock state when the unlock command is output, and the detection device detects the unlock state. When the lock device is not switched to the unlock state even if the unlock instruction is received and the unlock state cannot be detected, it can be diagnosed that the lock failure has occurred. Therefore, even in the case where there is no sign of the failure of the locking device when the charging connector is connected to the outlet, the failure of the locking device can be diagnosed. Preferably the locking means comprises a locking pin driven by an actuator, The detection means detects the locked state and the unlocked state based on t
