The invention relates to a power-off method and system of a domain controller, a control assembly and an intelligent driving vehicle, the method is applied to a micro control unit (MCU) of the domain controller, the MCU is connected with one or more system-on-chip (SOC), and the method comprises the following steps: in response to an external power-off instruction, sending a power-off request to each SOC; wherein each SOC provides a running environment for the intelligent driving software of the vehicle, each SOC quits the intelligent driving software after receiving a power-off request and then quits an operating system, and each SOC sends a power-off completion signal to the MCU after finishing quitting the operating system; and when a power-off completion signal fed back by each SOC is received, executing a power-off operation. Through the steps of the method, the quit integrity and safety of the intelligent driving software and the operating system running in the SOC during power-off are improved, and electric quantity waste caused by power-off overtime is avoided.
本申请涉及一种域控制器的下电方法、系统、控制组件以及智能驾驶车辆,该方法应用于域控制器的微控单元MCU,该MCU连接一个或多个的系统级芯片SOC,该方法包括:响应于外部的下电指令,向各个SOC发送下电请求;其中,各个SOC为车辆的智能驾驶软件提供运行环境,各个SOC在接收到下电请求时退出智能驾驶软件之后退出操作系统,在完成退出操作系统时向MCU发送完成下电信号;在接收到各个SOC反馈的完成下电信号时,执行下电操作。通过上述方法的步骤,提高了在下电时SOC运行的智能驾驶软件及操作系统退出的完整性和安全性,并避免了因下电超时而造成的电量浪费。
