ABSTRACT:
A method is provided for at least approximately determining the frictional value utilized between a wheel and the roadway. The method uses a vehicle weight that is determined, at least approximately, and a momentary actuating energy of a brake that is determined during a braking action. The method calculates the frictional value from the momentary actuating energy, the vehicle weight, and the wheel braking factor. In another embodiment, the method determines, at least approximately, the momentary vehicle deceleration. The frictional value is calculated from the momentary vehicle deceleration during braking and the Earth's gravitational acceleration.
