In winter, kinematic characteristics of motion are determined by varying external conditions and environmental conditions that affect the coefficient of friction. External factors affect the contact area with the road wheels in two ways: by changing the properties of the surface and affecting the mechanical properties of the tire itself. Change of tire-surface interaction parameters causes a decrease in obtained acceleration and consequently extending the braking distance of the vehicle. This paper presents the results of experimental studies of intense winter braking on two surfaces with different state.
