The invention relates to a method for controlling a steering-by-wire system (1) of a road vehicle, the steering-by-wire system (1) comprising a steering wheel (3) coupled to a steering shaft (2), a wheel actuator (5) for rotating steerable wheels (4), a shaft sensor for detecting a rotation of the steering shaft (2), and a control unit (10), the control unit (10) is configured to calculate an operating signal of the wheel actuator (5) as a function of a signal detected by the axle sensor, the method comprising the following steps: determining an actual steering wheel angle (alpha) by means of the axle sensor; modifying the actual steering wheel angle (alpha) by applying an artificial hysteresis that produces an offset between the actual steering wheel angle (alpha) and the modified steering wheel angle (alphamod) to mimic the behavior of the electromechanical power steering mechanism; and calculating a motor torque request for the wheel actuator (5) as a function of the modified steering wheel angle ([alpha] mod).

    本发明涉及一种用于控制道路车辆的线控转向系统(1)的方法,其中,所述线控转向系统(1)包括与转向轴(2)耦接的方向盘(3),用于转动可转向的车轮(4)的车轮致动器(5),用于检测所述转向轴(2)的转动的轴传感器,以及控制单元(10),所述控制单元(10)用于根据所述轴传感器检测的信号计算所述车轮致动器(5)的操作信号,其中,所述方法包括以下步骤:通过所述轴传感器确定实际方向盘角度(α);通过应用人工迟滞来修改实际方向盘角度(α),所述人工迟滞在实际方向盘角度(α)和修改后的方向盘角度(αmod)之间产生偏移量,以模仿机电式动力转向机构的行为;以及根据修改后的方向盘角度(αmod),计算用于所述车轮致动器(5)的电机转矩请求。
