According to the steering wheel torque compensation method under the LCC working condition, multiple compensation judgment conditions are set, and when all the compensation judgment conditions are met at the same time, it is judged that the current high-speed running self-vehicle has the risk of deviation in LCC centering control; and then the difference Erray between the theoretical transverse acceleration Estay and the actual transverse acceleration ay is corrected through the transverse acceleration difference torque gain coefficient k, the compensation torque value CTrq of a steering wheel is calculated, the compensation torque value CTrq is compensated to the LCC corner request torque value, and the vehicle is guided to run in the middle.
本申请提供的一种LCC工况下的方向盘扭矩补偿方法,其设置了多条补偿判断条件,当同时满足所有的补偿判断条件时,判断当前高速行驶的自车存在LCC居中控制有发生偏移的风险,然后通过横向加速度之差扭矩增益系数k对理论横向加速Est_ay和实际横向加速度ay之差Err_ay进行修正,计算方向盘的补偿扭矩值CTrq,补偿到LCC转角请求扭矩值中,将车辆导向到居中行驶。
