The invention discloses a vehicle-mounted entertainment system power management interaction system and a vehicle, the vehicle-mounted entertainment system power management interaction system comprises an SOC, an MCU and a screen, the screen is respectively connected with the SOC and the MCU, the SOC is provided with a power supply core service module and an IPO interface, five GPIO pins are arranged between two chips of the SOC and the MCU, and three GPIO pins are input by the SOC and output by the MCU; the two signals are input by the MCU and output by the SOC; the GPIO pin is characterized in that the GPIO pin is connected with the chips at the two ends, one end of the GPIO pin controls input high-low level interruption, the other end of the GPIO pin receives output and triggers corresponding vehicle power supply state logic according to interruption, and vehicle power supply states comprise dormancy, semi-dormancy, power failure and work. According to the invention, the SOC and the MCU in the entertainment host can synchronize the state information through the high and low level change of the GPIO, the hot start performance of the vehicle-mounted terminal is finally improved, and the SOC has an active wake-up function.
本发明公开了一种车载娱乐系统电源管理交互系统及车辆,包括SOC、MCU和屏幕,屏幕分别与SOC、MCU连接,所述SOC具有电源核心服务模块和IPO接口,所述SOC与MCU两块芯片间布置有5个GPIO脚,其中3个由SOC输入,MCU输出;2个由MCU输入,SOC输出;所述GPIO脚的特性为连接两端芯片,一端控制输入高低电平中断,另一端接收输出,并根据中断触发对应车机电源状态逻辑,其中车机电源状态包括休眠、半休眠、断电和工作。本发明使娱乐主机内的SOC跟MCU能够通过GPIO的高低电平变化同步状态信息,最终达到提升车机的热启动性能,并使SOC拥有主动唤醒功能。
