The invention provides a torque compensation control method for a chassis domain EPS (electric power steering) system, which comprises the following steps of: acquiring current information of a vehicle, and performing oversampling symbol expansion, electric power control, motor characteristic compensation, vehicle characteristic compensation, stabilization compensation, rack tail end steering characteristic control and rudder protection vibration compensation on the acquired information; the calculated results are fused to obtain a target power-assisted torque; and performing quantitative noise weakening compensation on the target power-assisted torque and outputting the target power-assisted torque. The method is based on an electric steering power-assisted control strategy in chassis domain control, and has the characteristics of fast response, less hardware, low cost and high safety.
本发明提供一种底盘域EPS系统的扭矩补偿控制方法,包括:采集车辆当前信息,对采集的信息进行过采样符号扩张、电动助力控制、电机特性补偿、车辆特性补偿、安定化补偿、齿条末端操舵特性控制、保舵震动补偿后,将计算得到的结果进行融合、以得到目标助力扭矩;将目标助力扭矩进行量化噪声削弱补偿并输出。本发明基于底盘域控制中的电动转向助力控制策略,具有响应快、硬件少、成本低和安全性高的特点。
