The invention relates to a parameter estimation method and device, equipment, a medium, a program product and a vehicle, and the method comprises the steps: resetting an estimator of a peak road adhesion coefficient under the condition that the slip rate change rate of a wheel meets a preset sudden change condition; and determining a peak road adhesion coefficient of the wheel based on the reset estimator. The invention aims to improve the accuracy of peak road adhesion coefficient estimation in a scene with sudden change of road conditions.

    本申请涉及一种参数估计方法、装置、设备、介质、程序产品及车辆,其中,在车轮的滑移率变化率满足预设突变条件的情况下,重置峰值路面附着系数的估计器;基于重置后的估计器确定所述车轮的峰值路面附着系数。本发明旨在提高存在路面条件突变场景下的峰值路面附着系数估计的准确性。
