DEVICE AND METHOD FOR ESTIMATING FRICTIONAL CONDITION OF GROUND CONTACT SURFACE OF WHEEL

摘要

A device for estimating grip characteristics of the ground contact surface of a wheel of a vehicle. The device has an input section and an output section. The input section sets an input representing the ratio between wheel force acting at the ground contact surface on the wheel and the degree of wheel slip of the wheel. The output section determines an output representing a grip characteristics parameter indicating grip characteristics of the wheel.
