The invention relates to a method of controlling a steer-by-wire system (1) of a road vehicle. Wherein the steer-by-wire system (1) comprises a feedback actuator (8) for applying a feedback torque to the steering wheel (3) and a road wheel actuator (5) for rotating the steerable wheels (4), each having two redundant power packs, and the method comprises the following steps: a) if a fault (11) in the road wheel actuator is detected, the steering wheel (3) is driven by the steering wheel (3); if so, increasing the feedback torque provided by the feedback actuator (8) to a value (10) higher than the calculated feedback torque; b) if a fault (9) is detected in one of the power packs of the feedback actuator (8), increasing the feedback torque provided by the normally operating power pack of the feedback actuator to a value (10) higher than the calculated feedback torque.

    本发明涉及一种控制道路车辆的线控转向系统(1)的方法。其中线控转向系(1)包括用于向方向盘(3)施加反馈扭矩的反馈执行器(8)和用于使可转向车轮(4)转动的路轮执行器(5),每个路轮执行器具有两个冗余的动力组,并且该方法包括以下步骤:a)如果检测到路轮执行器中的故障(11),则将反馈执行器(8)提供的反馈转矩增加到高于计算出的反馈转矩的值(10);b)如果检测到反馈执行器(8)的一个动力组中的故障(9),则将反馈执行器的正常运行的动力组所提供的反馈转矩增加到高于计算出的反馈转矩的值(10)。
