The invention relates to an automobile controller power supply wake-up method and device, and relates to the technical field of automobile electronics, wherein the method comprises the following steps that: a hard wire wake-up signal, a bus wake-up signal and a wireless wake-up signal sent to an automobile controller are monitored; when the hard wire wake-up signal or the wireless wake-up signal is monitored, a chip enabling end of the main power supply chip is triggered to perform power supply wake-up on the automobile controller; when the bus wake-up signal is monitored, a chip enabling end of the main power supply chip is triggered by means of a preset CAN transceiver, and power supply wake-up is carried out on the automobile controller; and when the hard wire wake-up signal, the bus wake-up signal and the wireless wake-up signal are not monitored, the automobile controller maintains a dormant state. Wake-up and sleep control is carried out according to the type of the wake-up signal, the static power consumption of the automobile controller is reduced, and the situation that the storage battery of the whole automobile cannot be started due to power shortage caused by too large static power consumption of the automobile controller is avoided.

    本申请涉及一种汽车控制器供电唤醒方法及装置,涉及汽车电子技术领域,该方法包括以下步骤:监测向汽车控制器发送的硬线唤醒信号、总线唤醒信号以及无线唤醒信号;当监测到硬线唤醒信号或无线唤醒信号时,触发主电源芯片的芯片使能端,对汽车控制器进行供电唤醒;当监测到总线唤醒信号时,借助预设的CAN收发器触发主电源芯片的芯片使能端,对汽车控制器进行供电唤醒;当未监测到硬线唤醒信号、总线唤醒信号以及无线唤醒信号时,汽车控制器维持休眠状态。本申请根据唤醒信号的类别进行唤醒和休眠控制,降低汽车控制器的静态功耗,避免车辆因汽车控制器的静态功耗过大而导致整车蓄电池因亏电而无法启动。
