The invention relates to an integrated controller low-voltage power supply method, an integrated controller device and a vehicle. When a key switch is in an off state and a vehicle is charged, an integrated controller is awakened when receiving CAN bus information, a power supply relay coil is closed, low-voltage electricity is provided for the integrated controller, and the integrated controllernormally responds to the requirement of the whole vehicle. When charging is finished and the integrated controller does not receive CAN bus information within a certain period of time, the power supply relay coil is disconnected, low-voltage power supply is cut off, and meanwhile a main control chip enters a dormant state. The problem that in the vehicle charging process, when a key switch is turned off, related electrical equipment in a vehicle cannot work normally, and normal use is affected is solved.
本发明涉及一种集成控制器低压供电方法、集成控制器装置及车辆。钥匙开关处于关闭状态下,当为车辆充电时,当集成控制器收到CAN总线信息时被唤醒,将供电继电器线圈进行闭合,给集成控制器提供低压电,集成控制器正常响应整车需求;充电结束时,当集成控制器在一定时间内未收到CAN总线信息时,将供电继电器线圈进行断开,切断低压供电,同时主控芯片进入休眠状态。解决了在车辆充电过程中且钥匙开关打在关闭位置时,车辆中的相关电气设备无法正常工作,影响正常使用的问题。
