The invention provides a power supply circuit, a power supply method and an automatic driving vehicle, and relates to the technical field of electrics, in particular to the technical field of power supply control. According to the specific implementation scheme, a control unit is connected with a pre-charging unit and a wake-up signal input end, and is configured to respond to a wake-up signal not received from the wake-up signal input end and output a starting signal to the pre-charging unit; in response to the received wake-up signal, outputting a turn-off signal to the pre-charging unit; the pre-charging unit is connected with the energy storage unit and is configured to output a first charging voltage to the energy storage unit in response to the received starting signal; in response to the received closing signal, stopping outputting the first charging voltage; the protection unit is connected with the wake-up signal input end and the energy storage unit, and is configured to output a second charging voltage to the energy storage unit in response to the received wake-up signal; the energy storage unit is configured to receive the first charging voltage or a second charging voltage and store electric energy, and the second charging voltage is larger than the first charging voltage.

    本公开提供了一种供电电路、供电方法及自动驾驶车辆,涉及电气技术领域,尤其涉及电源控制技术领域。具体实现方案为控制单元与预充电单元和唤醒信号输入端连接,被配置为响应于未从唤醒信号输入端接收到唤醒信号,向预充电单元输出开启信号;响应于接收到唤醒信号,向预充电单元输出关闭信号;预充电单元与储能单元连接,被配置为响应于接收到开启信号,向储能单元输出第一充电电压;响应于接收到关闭信号,停止输出第一充电电压;保护单元与唤醒信号输入端和储能单元连接,被配置为响应于接收到唤醒信号,向储能单元输出第二充电电压;储能单元,被配置为接收第一充电电压或第二充电电压,并进行电能存储,其中,第二充电电压大于第一充电电压。
