The invention discloses a vehicle control method for resetting of a battery management system and a related device. The method comprises the steps that the battery management system can obtain a flag bit signal of a controller to determine whether the controller is reset or not; and when it is determined that the controller is reset, the battery management system sends a first signal to the vehicle control unit. The vehicle control unit receives the first signal and sends a closing request for closing the main relay to the battery management system; the battery management system can close the main relay based on the closing request, high-voltage power-on of the whole vehicle is achieved, and power output of the whole vehicle is maintained. By means of the method, after the battery management system is reset, the main relay can be automatically controlled to be closed, it is guaranteed that the whole vehicle can be powered on at high voltage, power output of the whole vehicle is recovered, a user cannot sense loss generated by resetting of the battery management system in the driving process, the driving experience of the user is improved, and the user experience is improved. And the driving safety is improved.
本申请公开了一种针对电池管理系统发生复位的整车控制方法及相关装置,该方法包括:电池管理系统可以获取控制器的标志位信号以确定控制器是否发生复位。当确定控制器发生复位时,电池管理系统向整车控制器发送第一信号。整车控制器接收到第一信号,向电池管理系统发送闭合主继电器的闭合请求。电池管理系统可以基于闭合请求闭合主继电器,实现整车的高压上电,维持整车动力输出。通过本申请所提供的方法,在电池管理系统发生复位后,可以自动控制主继电器闭合,保证整车可以高压上电,恢复整车的动力输出,使用户在行车过程中感知不到由于电池管理系统复位所产生的丢失,改善用户的行车体验,提高行车的安全性。
