The invention relates to a road feeling feedback method suitable for a steer-by-wire system. The road feeling feedback method comprises the following steps that (1) a road feeling feedback main torque Tmain used for feeding back road surface information and vehicle state information is obtained; 2) obtaining a road feeling feedback adjusting torque Ttun for adjusting the steering hand feeling of a driver; (3) the road feeling feedback torque Tsw of the vehicle is obtained according to superposition of the main torque and the adjusting torque and sent to the road feeling motor, and compared with the prior art, the method has the advantages that the road feeling authenticity is high, sensing is accurate, and a pull pressure sensor does not need to be arranged.
本发明涉及一种适用于线控转向系统的路感反馈方法,包括以下步骤:1)获取用以反馈路面信息与车辆状态信息的路感反馈主力矩Tmain;2)获取用以对驾驶员转向手感进行调节的路感反馈调节力矩Ttun;3)根据主力矩与调节力矩叠加获取车辆的路感反馈力矩Tsw并发送给路感电机,与现有技术相比,本发明具有路感真实性高、准确感知、无需布置拉压力传感器等优点。
