The invention discloses an automobile driving power supply system, a control method and an automobile. The automobile driving power supply system comprises a switch unit, a driving unit and a control unit, the first end of the switch unit is connected to a load, and the second end is connected to a high-voltage power supply; the driving unit is connected with the controlled end of the switch unit; the first end of the control unit is connected to the low-voltage power supply, and the second end of the control unit is connected with the controlled end of the driving unit; the control unit is used for stopping outputting a driving signal to the driving unit when the low-voltage power supply is powered down; and the driving unit is used for controlling the switch unit to disconnect the access between the high-voltage power supply and the load when the driving signal is not received. According to the invention, when the low-voltage power supply is powered down, the control unit controls the driving unit to turn off the access between the high-voltage power supply and the load; the task of closing the output of the high-voltage power supply in time when the low-voltage power supply is powered down can be completed, and the safety of the vehicle is improved.

    本发明公开一种汽车驱动电源系统、控制方法及汽车,所述汽车驱动电源系统包括:开关单元、驱动单元和控制单元;所述开关单元的第一端接入负载,第二端接入高压电源;所述驱动单元与所述开关单元的受控端连接;所述控制单元的第一端接入所述低压电源,第二端与所述驱动单元的受控端连接;所述控制单元,用于在所述低压电源掉电时,停止向所述驱动单元输出驱动信号;所述驱动单元,用于在未接收到所述驱动信号时,控制所述开关单元断开所述高压电源与所述负载之间的通路。本发明通过控制单元在低压电源掉电时,控制驱动单元关断所述高压电源与所述负载之间的通路;可以完成在低压电源掉电时及时关闭高压电源输出的任务,提高车辆的安全性。
