The invention provides an adhesion coefficient determination method and device, a vehicle and a storage medium, and relates to the technical field of automobiles. A first adhesion coefficient, a second adhesion coefficient and a third adhesion coefficient are obtained, the first adhesion coefficient is a historical maximum adhesion coefficient, the second adhesion coefficient is a real-time adhesion coefficient determined based on the driving data, and the third adhesion coefficient is an adhesion coefficient input by a slip control module; the slip control module is used for determining an adhesion coefficient based on the driving force and the vertical force of the wheels; determining that an adhesion coefficient selection process is triggered based on the driving data; based on the driving data, a target adhesion coefficient is determined from the first adhesion coefficient, the second adhesion coefficient and the third adhesion coefficient, and the target adhesion coefficient is used for carrying out driving control on the vehicle. Through the scheme, the target adhesion coefficient is more consistent with the driving data, so that the target adhesion coefficient is more accurate, and the accuracy of the adhesion coefficient is improved.
