The invention provides a double-source steering system control method, a vehicle control unit and a double-source steering system. The double-source steering system control method comprises the steps that vehicle state information and state feedback information transmitted by a high-pressure steering controller are obtained; according to the vehicle state information and the state feedback information, whether the high-pressure steering controller is abnormal or not and whether the vehicle has a steering demand or not are determined; and if the high-pressure steering controller is abnormal and the vehicle has the steering requirement, a low-pressure steering controller is controlled to drive a low-pressure oil pump to work so as to supplement hydraulic pressure to a steering device. According to the invention, hydraulic power-assisted uninterrupted switching can be realized, and the driving safety of the vehicle is guaranteed.
本发明提供一种双源转向系统控制方法、整车控制器及双源转向系统,所述双源转向系统控制方法包括:获取车辆状态信息和高压转向控制器传输的状态反馈信息;根据所述车辆状态信息和所述状态反馈信息确定所述高压转向控制器是否异常,以及车辆是否有转向需求;如果所述高压转向控制器异常,且车辆有转向需求,则控制低压转向控制器驱动低压油泵工作以向转向装置补充液压。本发明能够实现液压助力无中断切换,保障了车辆行驶安全。
