The embodiment of the invention provides an adhesion coefficient determination method and device, a vehicle, a medium and a program product. The method comprises the following steps: acquiring tire information of each tire of the vehicle, wherein the tire information comprises tire longitudinal force, tire lateral force and tire vertical load of the tire; determining a first adhesion coefficient of the vehicle according to the tire information of each tire; determining a gain coefficient according to the first adhesion coefficient and the tire information of each tire; determining a second adhesion coefficient according to the gain coefficient and the acceleration of the vehicle; and determining a target adhesion coefficient of the vehicle according to the first adhesion coefficient and the second adhesion coefficient. According to the method, the accuracy of determining the target adhesion coefficient of the vehicle is improved, so that the target adhesion coefficient of the vehicle is matched with the actual condition, the anti-skid control of the vehicle is improved, and the safety of passengers is improved.
