The invention provides a road feature processing method for a vehicle and a road feature processing system, and the method comprises the steps: calculating the transverse gradient and longitudinal gradient acceleration of a road, calculating the steering wheel angle compensation amount according to the transverse gradient, and calculating the wheel torque compensation amount according to the longitudinal gradient acceleration; the bumping degree of the road is calculated, and the limiting amplitude of the steering wheel turning angle change rate is set according to the bumping degree; and judging whether the vehicle runs on the bridge or in the tunnel based on the height variation of the vehicle in the given time period. According to the technical scheme of the invention, active identification and processing of road features are realized, the control effect of the vehicle is improved, and the stability and safety of vehicle driving are ensured.

    本申请提供一种用于车辆的道路特征处理方法以及一种道路特征处理系统,所述方法包括计算道路的横向坡度和纵向坡度加速度,并根据横向坡度计算方向盘转角补偿量,以及根据纵向坡度加速度计算车轮扭矩补偿量;计算道路的颠簸程度,并根据颠簸程度设定方向盘转角变化率的限制幅值;以及基于车辆在给定时间段内的高度变化量判断车辆是否在桥梁上或隧道内行驶。根据本申请的技术方案,实现了对道路特征的主动识别和处理,提高了车辆的控制效果,保证了车辆行驶的稳定性和安全性。
