Abstract:
Apparatus for estimating a ground contact surface gripping characteristic of a vehicle wheel of a vehicle comprises an input section and an output section. The input section sets an input representing a ratio of a wheel force acting on the vehicle wheel in the ground contact surface, and a wheel slipping degree of the vehicle wheel. The output section determines, from the input, an output representing a grip characteristic parameter indicative of the gripping characteristic of the vehicle wheel.
