The invention relates to a control system of an automobile, in particular to a shutdown method and system for an application system during flameout of the automobile. The shutdown method for the application system during flameout of the automobile comprises the following steps that after an MCU system detects an automobile flameout signal, the application system is notified to prepare to be shut down; after receiving the shutdown signal, the application system starts to be shut down, and the application system sends a shutdown notice to the MCU system through the GPIO module after being shut down; and the MCU system powers off the application system. According to the shutdown method for the application system during flameout of the automobile, the application system is powered off after it is detected that the application system is shut down, and it can be ensured that the storage medium is not damaged.
本发明涉及一种汽车的控制系统,尤其是汽车熄火时应用系统的关机方法及系统。汽车熄火时应用系统的关机方法,包括以下步骤:MCU系统检测到车辆熄火信号后通知应用系统准备关机;应用系统接到关机信号后开始关机,所述应用系统在关机后通过GPIO模块给MCU系统发出已关机通知;MCU系统给应用系统下电。本发明提供的汽车熄火时应用系统的关机方法通过检测到应用系统关机后再给应用系统下电,能确保存储介质不受损害。
