The invention provides a vehicle braking deviation processing method and device, equipment, a medium and a program product. The method comprises the steps that target acting force borne by a vehicle under target braking deceleration is determined; simulating a target wheel turning angle of the vehicle under the target acting force through a steering and suspension dynamical model, and simulating a default wheel turning angle of the vehicle under the default acting force; calculating a difference value between the target wheel rotation angle and the default wheel rotation angle as a vehicle braking rotation angle; and parameter adjustment is conducted on the steering and suspension dynamical model according to the vehicle braking angle, and vehicle target parameters are obtained. Through multi-body dynamics software modeling, the workload is small, and the simulation efficiency is high; and wheel turning angle simulation is carried out based on the model established by the multi-body dynamics software, so that the model is optimized according to the wheel turning angle, the vehicle has a more reasonable wheel turning angle during braking, the phenomenon of deviation is reduced, and the braking stability and safety of the vehicle are improved.
