The invention provides a control method of a new energy vehicle charging port electronic lock control system which meets the function safety requirements. According to the control method, whether a control end circuit has a hardware fault or not is judged while locking operation and unlocking operation are executed, and if the hardware fault exists, the electrical level of a locking control end and an unlocking control end of the controller is adjusted to prevent the electronic lock from being in a continuous locked or continuous unlocked status, and meanwhile, the electronic lock returns to ahardware fault status. While the electronic lock is effectively controlled to be locked or unlocked, the electronic lock and a vehicle can be protected in the case of related faults of the electroniclock, and the safety level is greatly improved.
本发明提供了一种满足功能安全要求的新能源车充电口电子锁控制系统的控制方法,在执行上锁操作和解锁操作的同时,判断控制端电路是否有硬件故障,如有硬件故障则通过控制器的上锁控制端和解锁控制端电平,避免电子锁处于持续上锁或持续解锁状态,同时返回电子锁硬件故障状态。本发明在有效控制电子锁上锁或解锁的同时,能在发生电子锁相关故障的时候保护电子锁和车辆,大大提高了安全等级。
