METHOD FOR ESTIMATING THE ROLLING RESISTANCE OF A VEHICLE WHEEL

摘要

A method for estimating rolling resistance of a wheel of a moving vehicle, the vehicle including at least two wheels fitted with tires, the method including: measuring or estimating a value of angular velocityΩof rotation of at least one wheel; and measuring or estimating a value of torque T applied to the wheel; the method using an observer of dynamics of the wheel that is based on a sliding mode control theory, in which input signals are the value of the angular velocityΩof the wheel and the value of the torque T applied to the wheel.
