The embodiment of the invention provides a road feel feedback torque control system and method, a vehicle, a medium and a sensing unit. The system comprises a sensing unit used for acquiring a torque signal when a steering rack moves to drive a torsion bar to twist; and the feedback torque calculation module is used for obtaining a basic torque, obtaining a compensation torque according to the torque signal, and obtaining a target feedback torque based on the basic torque and the compensation torque. According to the scheme, the sensing unit is connected with the steering rack, various road condition information including road surface high-frequency vibration, sudden steering of steering wheels and the like can be sensed more sensitively, and the various road condition information can be timely and accurately converted into hand feeling feedback torque to be fed back to a driver.

    本申请实施例提供路感反馈力矩控制系统、方法、车辆、介质及传感单元。该系统包括:传感单元,用于获取转向齿条移动时带动扭杆发生扭转时的扭矩信号;反馈力矩计算模块,用于获取基础力矩,用于根据所述扭矩信号获取补偿力矩,还用于基于所述基础力矩和所述补偿力矩,获取目标反馈力矩。通过上述方案,传感单元与转向齿条连接,能够更加灵敏的感知各种路况信息,包括路面高频率振动、转向轮突然转向等,能够将各种路况信息及时准确的转换为手感反馈力矩反馈给驾驶员。
