About Interrelation Between the Tire Grip Properties and the Wheel Sliding 2001-01-3338
The investigation is concerned with dependencies between a friction coefficient of the tire with a road, μ, and wheel slip, s.
The analysis of μ-s-dependencies is given in the paper. The conventional approach to their presentation contains some discordance with real physical processes. On the basis of the external friction theory it is possible to offer another concept of potential μ-s-curves. The potential μ-s-curve is a function of the deformative, adhesion and transverse components of tire grip, the absolute slip velocity and the road reaction. Over the interrelation character of the given components it is possible to evaluate a current road-operational situation.
In addition the recommendations for practical use of the potential μ-s-dependencies for the Systems of Active Safety are given.
