The invention relates to a power supply management method for an electronic control unit of a motor vehicle and a corresponding power supply management system. An electronic control unit has a main power supply and a standby power supply. The power supply management method is based on an automobile open system architecture. In the power management method, if it is desired that the electronic control unit stops working, a shutdown operation is performed and the main power supply is shut down; in the shutdown operation, a backup mode in which the electronic control unit is maintained in a backupstate with a backup power source and wake-up source detection is performed at a determined polling period, and in the case where a wake-up source is detected, the electronic control unit is waken upcan be selected.
本发明涉及一种用于汽车的电子控制单元的电源管理方法以及相应的电源管理系统。电子控制单元具有主电源和备用电源,所述电源管理方法基于汽车开放系统架构,在所述电源管理方法中,如果希望电子控制单元停止工作,则执行关闭操作并关闭主电源;在所述关闭操作中,能够选择备用模式,在所述备用模式中利用备用电源使电子控制单元维持备用状态并以确定的轮询周期进行唤醒源检测,在检测到唤醒源的情况下唤醒电子控制单元。
