The invention relates to an automobile power supply management control method, an automobile power supply management control method and a remote controller control method, and the method comprises the following steps: after an automobile ignition switch is OFF and the whole automobile is powered off, an I-type electric appliance controller transmits various memory parameters to a BCM (Body Control Module) storage space of an automobile body controller for storage, and sends a power-off instruction message; when the vehicle is powered off, timing is started, and when a timer of the III-type electric appliance controller reaches preset time, a power-off message is output to a vehicle body controller BCM through a CAN network structure until the vehicle body controller BCM receives the power-off message of the controller with the longest preset time; when the vehicle body controller BCM receives a message that the electric appliance controller can be powered off, the vehicle body controller BCM outputs a power-off pulse to control the magnetic latching relay to realize contact disconnection, and the vehicle is always powered off; and when the cabin area controller CDC and the vehicle body controller BCM reach the network dormancy condition, the whole vehicle network is dormant, and the electrostatic current of the whole vehicle is reduced to the minimum. According to the invention, quiescent current consumption of the whole vehicle can be reduced fundamentally.

    本发明涉及一种汽车电源管理控制及其控制、远程控制控制器方法,该方法包括的步骤为:车辆点火开关置于OFF,整车下电后,I类电器控制器将各种记忆参数传输给车身控制器BCM存储空间进行存储,并发出可断电指令报文;车辆下电开始计时,当III类电器控制器定时器达到预设时间,通过CAN网络结构向车身控制器BCM输出可断电报文,直到车身控制器BCM收到最长预设时间控制器的可断电报文;当车身控制器BCM接收到电器控制器可断电报文后,车身控制器BCM输出断电脉冲控制磁保持继电器实现触点断开,车辆常电掉电;当座舱域控制器CDC、车身控制器BCM达到网络休眠条件,整车网络休眠,整车静电电流降到最低。本发明能从根本上减少整车的静态电流消耗。
