The invention discloses a power supply system for vehicle-mounted auxiliary driving equipment. The power supply system comprises a first power supply branch which supplies power to the SOC according to a first power supply; the second power supply branch supplies power to the SOC according to a second power supply; the third power supply branch takes power from the first power supply branch to supply power to the MCU, and when the vehicle-mounted auxiliary driving equipment is in a low-power-consumption mode, a first control signal generated by the MCU is used for controlling the first power supply branch to be disconnected; the first voltage monitoring circuit generates a second control signal based on the first power supply; the second voltage monitoring circuit generates a third control signal based on the second power supply. The first power supply branch comprises first and second switch elements which are connected in series; and the first control circuit controls on-off of the first power supply branch according to the first control signal and the second control signal. The second power supply branch comprises third and fourth switch elements which are connected in series; and the second control circuit controls the on-off of the second power supply branch according to the second control signal and the third control signal.

    本发明公开了一种用于车载辅助驾驶设备的供电系统。供电系统包括:第一供电支路,根据第一电源向SOC供电;第二供电支路,根据第二电源向SOC供电;第三供电支路,自第一供电支路取电以向MCU供电,MCU在车载辅助驾驶设备处于低功耗模式时,生成的第一控制信号用于控制第一供电支路断开;第一电压监测电路,基于第一电源,生成第二控制信号;第二电压监测电路,基于第二电源生成第三控制信号。第一供电支路包括串联的第一和第二开关元件;以及第一控制电路,根据第一和第二控制信号控制第一供电支路的通断。第二供电支路包括串联的第三和第四开关元件;以及第二控制电路,根据第二和第三控制信号控制第二供电支路的通断。
