The invention discloses a steering system double-source switching control system and method. The steering system double-source switching control system comprises a low-voltage steering controller, a high-voltage steering controller, a steering motor, a vehicle controller, a high-voltage power supply and a low-voltage power supply; the low-voltage steering controller is connected with the steeringmotor and the low-voltage power supply; the high-voltage steering controller is connected with the high-voltage power supply and the steering motor; and the low-voltage controller, the high-voltage controller and the vehicle controller are connected through communication wire harnesses. The rotating speed of the steering motor is actively judged through the low-voltage steering controller to decide whether to be switched into the low-voltage steering power, a command of the vehicle controller does not need to be waited any more, the high and low voltage switching time is saved, when low-voltage switching-in is unsuccessful for the first time, multiple times of switching-in can be tried, the success rate of high and low voltage switching is increased, and safety is improved.

    本发明公开了一种转向系统双源切换控制系统及方法,其中控制系统包括低压转向控制器、高压转向控制器、转向电机、整车控制器、高压供电电源以及低压供电电源,所述低压转向控制器连接转向电机以及低压供电电源,高压转向控制器连接高压供电电源以及转向电机,低压控制器、高压控制器以及整车控制器之间通过通信线束连接。本发明由低压转向控制器主动判断转向电机转速决定是否切入低压转向助力,不再需要等待整车控制器的命令,节省了高低压切换的时间,并且在首次低压切入不成功时还会尝试切入多次,增加了高低压切换的成功率,提高安全性。
