METHOD AND DEVICE FOR CONTROLLING THE SLIPPAGE OF A WHEEL FOR AN AUTOMOTIVE VEHICLE

摘要

Method and device for controlling the slippage of a wheel for an automotive vehicle. The invention relates to a method and a device for controlling the slippage of an automotive vehicle drive wheel by regulating the driving torque delivered to the wheels in the event the slippage exceeds a predefined threshold, so that, when a situation is detected of rolling at a speed (V) greater than a defined threshold on a road with poor adhesion, the drive wheels skid, it separately applies two modes of regulating the drive torque, depending on the level of slippage, either in the case of a slippage (S<SUB>x</SUB>) greater than a first threshold (S<SUB>1</SUB>), a closed loop regulation mode by automatic control of the speed of rotation of the wheels (?<SUB>r</SUB>) at a speed setting (?<SUB>r</SUB>
