The invention relates to a method for controlling an electric power steering system of a motor vehicle, comprising a front axle steering device (2) having a self-locking front axle steering actuator (20) by means of which two front wheels (FL, FR) can be steered in a coupled manner, and a rear axle steering device (3) having a self-locking rear axle steering actuator (30) by means of which two rear wheels (FL, FR) can be steered in a coupled manner, the two rear wheels (RL, RR) can be steered in a coupled manner, and wherein the following method steps are provided: determining that one of the steering devices (2, 3) has a fault; the malfunctioning steering device (2, 3) is switched off and the malfunctioning-free steering device (2, 3) is controlled, a steering controller (20, 30) of the malfunctioning-free steering device (2, 3) being controlled in such a way that the motor vehicle achieves a target movement resulting from a steering movement introduced into the steering wheel or a target movement given by the autonomous driving mode.

    本发明涉及一种用于控制机动车的电动转向系统的方法,所述机动车包括具有自锁的前桥转向调节器(20)的前桥转向装置(2)和具有自锁的后桥转向调节器(30)的后桥转向装置(3),两个前轮(FL,FR)能够借助于所述前桥转向调节器耦联地转向,借助所述后桥转向调节器能够使两个后轮(RL,RR)耦联地转向,其中,设置有以下方法步骤:确定所述转向装置(2,3)中的一个具有故障;断开有故障的转向装置(2,3)并且控制无故障的转向装置(2,3),其中,无故障的转向装置(2,3)的转向调节器(20,30)被控制,从而使机动车实现由导入到方向盘中的转向运动得出的理论运动或者使机动车实现由自主行驶模式给定的理论运动。
