The invention provides a road surface peak adhesion coefficient detection method, a related device and a vehicle. The detection method comprises the following steps: acquiring a longitudinal slip rate of a wheel based on a driving state parameter of the vehicle; determining that the wheel is in a first working state based on the longitudinal slip rate of the wheel; and obtaining at least one road surface estimation adhesion coefficient when the wheel is in the first working state, and determining the maximum value in the at least one road surface estimation adhesion coefficient as a road surface peak adhesion coefficient. By adopting the method, the detection precision of the road surface peak adhesion coefficient can be improved, meanwhile, the vehicle driving working condition range for detecting the road surface peak adhesion coefficient is expanded, the cost is low, the operation is simple, and the applicability is high.
