Abstract

In a method for determining the coefficient of friction between a vehicle tire and a roadway one of the vehicle wheel is pressurized during normal brake operation at a higher pressure than another wheel. The rotational speed of the braked wheel is compared with the rotational speed of another non-braked wheel for determining the wheel slip. Furthermore, the axle load of the braked wheel is measured. On the basis of wheel slip, brake torque and axle load, the coefficient of friction is determined.
