The invention discloses a vehicle running road surface characteristic parameter identification system and method, and the method comprises the steps: determining a dominant parameter representing the mechanical characteristics of a road surface, measuring a wheel force/torque and a slip rate, and estimating the estimated value of the road surface dominant parameter according to the measured values; and comparing the estimated value of the road surface dominant parameter with data in a road surface parameter database to obtain the current road surface type. According to the method, road surface parameter changes caused by wheel motion state changes or other factors can be rapidly tracked, influences of illumination and weather environments do not need to be considered, the calculation speed is high, robustness is high, and the method is suitable for online analysis.

    本发明公开了一种车辆行驶路面特性参数辨识系统与方法,方法包括:确定表征路面力学特性的主导性参数,测量车轮力/力矩、滑转率,根据前述测量值估计出路面主导性参数的估计值;然后将路面主导性参数的估计值与路面参数数据库中数据进行对比,得出当前路面类型。本发明能快速跟踪由于车轮运动状态改变或者其他因素导致的路面参数变化,且无需考虑光照、天气的环境的影响,计算速度快,鲁棒性强,适用于在线分析。
