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.
