The invention relates to a method of controlling a steering-by-wire system (1) of a road vehicle, the steering-by-wire system (1) comprising a steering device (3), a wheel actuator (5) for actuating a wheel (4) and a control unit (10), the control unit (10) calculating a motor torque request for the wheel actuator (5) as a function of an actual position or an estimated position and a position request, the position request is obtained on the basis of the position of the steering device (3), the following steps being provided: detecting a power limit situation of a wheel actuator; modifying the position request to enable the wheel actuator (3) to follow the position request within a power limit range; and calculating the motor torque request for the wheel actuator (5) using the modified position request.

    本发明涉及一种控制道路车辆的线控转向系统(1)的方法,所述线控转向系统(1)包括转向装置(3)、用于致动车轮(4)的车轮致动器(5)和控制单元(10),所述控制单元(10)根据实际位置或估计位置,和位置请求,计算用于所述车轮致动器(5)的电机转矩请求,所述位置请求是基于所述转向装置(3)的位置得到的,其中,提供了以下步骤:检测车轮致动器的功率限制情况;修改所述位置请求,以使所述车轮致动器(3)能够在功率限制范围内跟随所述位置请求;以及使用已修改的位置请求来计算用于所述车轮致动器(5)的所述电机转矩请求。
