ABSTRACT:
A process for reducing the yawing moment that develops during hard braking in a vehicle equipped with an anti-lock braking system (ABS) and traveling on a roadway having different coefficients of friction on opposite sides of the vehicle is disclosed. The driver must compensate for the yawing moment by steering towards the side that has the lower coefficient of friction. The process comprises venting the brake cylinder of the front wheel on the side with the higher coefficient of friction for a time t.sub.AH that is calculated in an electronic control module. The algorithm for computing t.sub.AH depends on the venting time t.sub.AL at the front wheel on the side with the lower coefficient of friction and the maximum or so-called deregulating pressures attained in the cylinders of the rear wheels. The electronic control module receives pressure information from pressure sensors and ascertains the venting time t.sub.AL that the ABS produces at the slipping front wheel. The algorithm used by the electronic control module attenuates the yawing moment in a way that adapts automatically to changing road conditions and vehicle types or loads. This contributes to a shortening of the overall braking distance while maintaining controllability of the vehicle.
