The invention discloses a power-off control method of an electric vehicle, a controller and the electric vehicle, and realizes intelligentization of high-voltage power-off, so that the energy consumption of the vehicle and the probability of safety accidents are reduced. The method comprises the following steps: acquiring vehicle monitoring information when the electric vehicle is in a starting state; according to the vehicle monitoring information, whether a driver leaves a seat or not is judged, if yes, a high-voltage power-off link in the whole vehicle power-off process is triggered, and the vehicle is triggered to send out prompt information when high-voltage power-off is completed; judging whether feedback information which is given by the driver and meets preset requirements is received within first preset time or not, and if yes, triggering the vehicle to recover high-voltage power-on; and if not, the vehicle is triggered to continue to execute the whole vehicle power-off process until the whole process is executed.

    本申请公开了一种电动汽车下电控制方法、控制器和电动汽车,实现了高压下电的智能化,从而降低了车辆能耗和安全事故发生的概率。该方法包括:获取电动汽车处于启动状态时的车辆监控信息;根据所述车辆监控信息判断驾驶员是否离座,若是,触发整车下电流程中的高压下电环节,并在高压下电完成时触发车辆发出提示信息;判断在第一预设时间内是否接收到驾驶员给出的符合预设要求的反馈信息,若是,触发车辆恢复高压上电;若否,触发车辆继续执行所述整车下电流程,直至整个流程执行完毕。
