The embodiment of the invention provides a transverse adhesion coefficient determination method and device, a vehicle, a medium and a program product. The method comprises the following steps: acquiring a plurality of rack forces and a plurality of front axle lateral forces of the vehicle at a plurality of historical moments; determining first statistical information according to the plurality of front axle lateral forces; determining second statistical information according to the plurality of rack forces and the plurality of front axle lateral forces; and performing fitting processing on the first statistical information and the second statistical information through a least square method to obtain a transverse adhesion coefficient. According to the method, the accuracy of determining the transverse adhesion coefficient is improved, the control effect of the vehicle is improved, and the safety of passengers is improved.
