The embodiment of the invention provides a dynamic adhesion coefficient determination method and device, a vehicle, a medium and a program product. The method comprises the following steps: determining an instantaneous adhesion coefficient, a longitudinal stability factor and a transverse stability factor of a vehicle; according to the instantaneous adhesion coefficient, the longitudinal stability factor and the transverse stability factor, determining a first dynamic adhesion coefficient and a first confidence coefficient of the vehicle in a high adhesion state and a second dynamic adhesion coefficient and a second confidence coefficient of the vehicle in a low adhesion state; and determining the dynamic attachment coefficient of the vehicle according to the first dynamic attachment coefficient, the first confidence coefficient, the second dynamic attachment coefficient and the second confidence coefficient. According to the method provided by the embodiment of the invention, the accuracy of determining the dynamic adhesion coefficient of the vehicle is improved.
