The invention discloses a power recovery method and device for a new energy automobile, a terminal and a storage medium, and the method comprises the steps: storing a key variable into a specific storage area in real time within the duration of a current driving cycle; when the VCU is reset and awakened and initialized again, reading the stored target key variable; based on the target key variable, the working state of the vehicle when resetting occurs is judged; when the vehicle is judged to be in the driving state, entering a communication waiting state; if the communication recovery is identified, identifying the actual state of the BMS relay; when it is recognized that the BMS relay is in the closed state, the interior of the VCU is restored to be in a high-voltage state; sending a drivable state entering instruction to the interior of the VCU; sending a target gear switching instruction into the VCU, wherein the target gear is a gear included in the target key variable; and the vehicle gear is switched to the target gear. By means of the method, automatic recovery after accidental reset of the vehicle control unit can be achieved.
本申请公开了一种用于新能源汽车的动力恢复方法、装置、终端及存储介质,其中方法包括:在当前驾驶循环的持续时间内,将关键变量实时存储入特定存储区域;在VCU发生复位并重新唤醒初始化时,读取存储有的目标关键变量;基于目标关键变量,判断发生复位时车辆的工作状态;当判断出车辆处于行驶状态时,进入等待通讯状态;若识别到通讯恢复,则识别BMS继电器的实际状态;当识别到BMS继电器处于闭合状态时,将VCU内部恢复为高压状态;向VCU内部发送进入可驱动状态指令;向VCU内部发送目标挡位切换指令,目标挡位为目标关键变量中所包含的挡位;将车辆挡位切换为目标挡位。本申请通过上述方法,能够实现整车控制器意外复位后的自动恢复。
