The embodiment of the invention relates to the technical field of intelligent driving, and particularly discloses a lane centering control compensation method and system under the wear state of a steering device. According to the embodiment of the invention, when the vehicle lane centering control function is started for the first time, the average inherent deviation T1 of the vehicle is calculated; when the vehicle lane centering control function is started subsequently, intelligent driving monitoring is carried out, a torque deviation variance delta 2 is calculated according to the average inherent deviation T1, and when a preset compensation condition is met, a transverse deviation compensation value offset 1 is calculated according to the torque deviation variance delta 2, and lane centering control compensation is carried out. The problem that a steering system assembly is abraded due to long-term driving of a vehicle, and consequently the vehicle centering control effect is poor can be solved, the function experience feeling of a driver is improved, and the personal safety of the driver can be guaranteed.

    本发明实施例涉及智能驾驶技术领域,具体公开了一种转向装置磨损状态下的车道居中控制补偿方法及系统。本发明实施例通过在车辆车道居中控制功能首次开启时,计算车辆的平均固有偏差△T1;在车辆车道居中控制功能后续开启时,进行智能驾驶监测,根据平均固有偏差△T1,计算扭矩偏差方差δ2,并在达到预设补偿条件时,根据扭矩偏差方差δ2,计算横向偏差补偿值△offset1,进行车道居中控制补偿。能够解决由于车辆长期驾驶导致转向系统组件磨损,导致车辆居中控制效果不佳的问题,提升驾驶员功能体验感,且能够保障驾驶员的人身安全。
