The invention provides a power supply control method and device, an Internet of Vehicles terminal and a readable storage medium, and relates to the technical field of Internet of Vehicles, and the method comprises the steps: sending a pre-standby dormancy signal to a microprocessor when it is confirmed that a dormancy state can be entered, and turning off a current peripheral power supply and entering the dormancy state when a standby dormancy confirmation signal is received, and pulling down the pin level in the dormant state of the microcontroller so as to indicate the singlechip to turn off the power supply of the microcontroller and perform dormancy. According to the technical scheme, by arranging the single chip microcomputer connected with the microcontroller, when the microcontroller and the microprocessor in the Internet of Vehicles terminal enter the dormancy state, the single chip microcomputer can cut off the power supply of the microcontroller, so that only the dormancy current of the single chip microcomputer and the dormancy current of the microprocessor exist when the whole Internet of Vehicles terminal is in the dormancy state; and the sleep current of the microcontroller is reduced, so that the power consumption of the whole Internet of Vehicles terminal during sleep is reduced.
本申请提供一种电源控制方法、装置、车联网终端和可读存储介质,涉及车联网技术领域,该方法包括:在确认可进入休眠状态时,发送预待机休眠信号至微处理器,在接收到待机休眠确认信号时,关闭当前外设电源并进入休眠状态,将微控制器的休眠状态引脚电平拉低以指示单片机关闭微控制器电源并进行休眠。该技术方案中,通过设置与微控制器连接的单片机,当车联网终端中的微控制器以及微处理器均进入休眠之后,单片机可以切断微控制器的电源,使得整个车联网终端在休眠时只存在有单片机的休眠电流以及微处理器的休眠电流,减去了微控制器的休眠电流,从而降低了整个车联网终端休眠时的功耗。
