The invention provides a power supply control circuit and method of vehicle-mounted electronic equipment and the vehicle-mounted electronic equipment. The power control circuit comprises a power interface, a power circuit, a controller and a sleep wake-up circuit. The power supply circuit comprises a hard wire signal enabling end and a bus signal enabling end. And the controller is electrically connected with the power supply circuit. The dormancy awakening circuit is electrically connected with the power interface and the bus signal enabling end and comprises a bus connecting end, the bus connecting end is used for being connected with a network bus and receiving a bus awakening signal input by the network bus, and the bus awakening signal is used for awakening the power circuit; the dormancy wake-up circuit is used for generating a disable signal when the bus connection end does not receive the bus wake-up signal within an initial set duration when the power interface is connected to a power supply; and the power supply circuit is used for not outputting electric energy to the controller when the hard wire signal enabling end does not receive the hard wire signal and the bus signal enabling end receives the disable signal, so that the controller is not electrified and started. The embodiment of the invention can reduce power consumption.

    本申请提供一种车载电子设备的电源控制电路、方法及车载电子设备。电源控制电路包括电源接口、电源电路、控制器及休眠唤醒电路。电源电路包括硬线信号使能端和总线信号使能端。控制器与电源电路电连接。休眠唤醒电路与电源接口和总线信号使能端电连接,且包括总线连接端,总线连接端用于与网络总线连接,接收网络总线输入的总线唤醒信号,总线唤醒信号用于唤醒电源电路;休眠唤醒电路用于在电源接口接入电源的初始设定时长内,总线连接端未接收到总线唤醒信号时,产生不使能信号;电源电路用于在硬线信号使能端未接收到硬线信号,且总线信号使能端接收到不使能信号时,不输出电能给控制器,使控制器不上电启动。本申请实施例可降低功耗。
