The invention discloses a vehicle power supply system and a power supply control method. The vehicle power supply system comprises a first power supply module, a second power supply module, a controlmodule and a power switch module, wherein the second power supply module is externally connected with a load through the power switch module, the first power supply module is externally connected withthe load, and the control module is connected with the load and the power switch module; the first power supply module is used for supplying power to the load; the control module is used for detecting the power supply condition of the first power supply module to the load, generating a switching signal based on the load power supply condition and sending the switching signal to the power switch module; the power switch module is used for determining a switching state of the power switch module based on the received switching signal; and the second power supply module is used for supplying power to the load based on the switching state of the power switch module. According to the embodiment of the invention, the control module detects the power supply conditions of the power supply modulesto the load, generates the switching signal according to the power supply conditions to control the state of the power switch modules, realizes mutual independence and no mutual influence of the twopower supply modules, and meets power supply requirements of automatic driving.

    本发明公开了一种车辆供电系统及供电控制方法。包括:第一供电模块,第二供电模块,控制模块,电源开关模块;其中第二供电模块通过电源开关模块外接负载,第一供电模块外接负载,控制模块分别与负载和电源开关模块连接;第一供电模块用于为所述负载供电;控制模块用于检测第一供电模块为负载供电情况;基于负载供电情况生成开关信号发送至电源开关模块;电源开关模块用于基于接收到开关信号确定电源开关模块的开关状态;第二供电模块用于基于电源开关模块的开关状态为负载供电。本发明实施例通过控制模块检测供电模块为负载供电情况,根据供电情况生成开关信号控制电源开关模块状态实现两个供电模块相互独立互不影响,满足自动驾驶的供电需求。
