The invention provides a steer-by-wire steering system, a method of controlling the steer-by-wire steering system, and a vehicle. The steer-by-wire steering system includes: a rotatable steering shaft; a driver-operated steering input member connected to the steering shaft; first and second torque feedback motors having output shafts connected to the steering shaft and each operable to apply a feedback torque or an offset torque to the steering shaft; the system further comprises: means for measuring the angular position of the steering shaft; means for determining the angular acceleration of the steering shaft; means for establishing or determining an envelope of the measured or calculated angular acceleration of the steering shaft; means for determining the magnitude of the offset torque applied by the motor as a function of the envelope of the angular acceleration of the steering shaft modified by the scaling factor, whereby a maximum defined offset torque is applied at a maximum defined amplitude and angular acceleration of the steering shaft.
本发明提供一种线控转向转向系统、控制线控转向转向系统的方法和车辆,所述线控转向转向系统包括:可旋转的转向轴;驾驶员操作的转向输入构件,连接到所述转向轴;第一扭矩反馈马达和第二扭矩反馈马达,具有连接到所述转向轴的输出轴并且各自可操作以向所述转向轴施加反馈扭矩或偏移扭矩;所述系统进一步包括:用于测量所述转向轴的角位置的装置;用于确定所述转向轴的角加速度的装置;用于建立或确定所述转向轴的所测量或计算的角加速度的包络的装置;用于根据通过缩放系数修改的转向轴的角加速度的包络确定由马达施加的偏移扭矩的大小的装置,由此在转向轴的最大限定幅度和角加速度下施加最大限定偏移扭矩。
