The embodiment of the invention provides a longitudinal adhesion coefficient determination method and device, a vehicle, a medium and a program product. The method comprises the following steps: determining a longitudinal adhesion coefficient of each wheel according to first wheel information of each wheel and a plurality of scene adhesion coefficients; the first wheel information comprises longitudinal rigidity, slip rate and nominal longitudinal force; according to the longitudinal attachment coefficients of the wheels, determining a first longitudinal attachment coefficient and a first confidence coefficient of the vehicle in a low attachment state and a second longitudinal attachment coefficient and a second confidence coefficient of the vehicle in a high attachment state; and determining the longitudinal adhesion coefficient of the vehicle according to the first longitudinal adhesion coefficient, the first confidence coefficient, the second longitudinal adhesion coefficient and the second confidence coefficient. According to the method provided by the embodiment of the invention, the accuracy of determining the longitudinal adhesion coefficient of the vehicle is improved.
