The invention provides a road surface peak adhesion coefficient determination method and device, electronic equipment and a storage medium, and relates to the technical field of automobile control, and the method comprises the steps: firstly, obtaining tire forces borne by wheels of a vehicle on a target road surface in multiple directions; secondly, determining a first utilization adhesion coefficient of the wheel and the target road surface according to the tire forces received in the multiple directions; then, determining a first wheel slip rate according to the vehicle speed of the vehicle and the wheel speed of the wheels; finally, a first peak adhesion coefficient of the target road surface is determined based on the first utilization adhesion coefficient and the first wheel slip rate. In the embodiment, the peak adhesion coefficient of the road surface is calculated by utilizing the mathematical model, so that the problems of poor repeatability, high cost and multiple influence factors existing in a test for measuring the road surface adhesion coefficient through an instrument are solved, and the calculation result is accurate and can be used as a reference for vehicle stability control.
