The invention discloses a vehicle control unit power-off management method which comprises the following steps: judging and analyzing whether a vehicle CAN (Controller Area Network) enters a sleep state or not, and timely processing the vehicle CAN according to a judgment and analysis result, so as to avoid the situation that the vehicle parking time is prolonged due to the fact that the CAN cannot enter the sleep state due to an ECU (Electronic Control Unit) fault and the electric quantity of a storage battery is consumed; and the user can still normally ignite and use the vehicle even after a long-time business trip, so that the vehicle use experience of the user is improved.

    本发明公开了一种整车控制器断电管理方法,通过对整车CAN网络是否进入休眠进行判定分析,根据判定分析结果对其进行及时处理,避免因ECU故障而导致CAN网络无法进入休眠,继而消耗蓄电瓶电量,从而增大车辆停放时间,用户即便长时间出差回来后依旧可以正常点火用车,提升用户用车体验感。
