SYSTEM AND METHOD TO ESTIMATE TIE-ROD FORCE AND CONTROL THE STEERING OF VEHICLE

A system and method for controlling the steering of a vehicle includes a processor, a velocity sensor in communication with the processor a steering angle sensor in communication with the processor, an accelerometer in communication with the processor and a steering angle controller in communication with the processor. The processor is configured to receive the acceleration of the vehicle from the accelerometer and the velocity from the velocity sensor, determine the estimated tie-rod force utilizing the lookup table tie-rod force estimation lookup table, and instruct the steering wheel angle controller to apply an additional force substantially equal to the estimated tie-rod force to the steering torque. 本发明公开了用于控制车辆的转向的系统和方法，其包括处理器、与处理器通信的速度传感器、与处理器通信的转向角度传感器、与处理器通信的加速度计以及与处理器通信的转向角度控制器。该处理器被配置为从加速度计接收车辆的加速度以及从速度传感器接收速度，利用查找表横拉杆力估计查找表确定估计的横拉杆力，并且指示方向盘角度控制器向转向扭矩施加基本上等于估计的横拉杆力的附加力。
