Abstract
A process for reducing yaw during braking in a vehicle having an anti-lock braking system (ABS) and traveling on a roadway having different coefficients of friction on opposite sides of the vehicle comprises regulating the braking pressures in the wheels of the vehicle during ABS-controlled braking so that a permissible braking pressure difference (.DELTA.P) between the braking pressures in the high and low wheels is maintained. The permissible braking pressure difference (.DELTA.P) is calculated by an electronic system based on an algorithm that takes into account the frictional value of the road, and/or the load on the vehicle, and/or the wheel base of the vehicle, and/or the wheel gauge of the vehicle, and/or the level of the center-of-gravity of the vehicle. The algorithm increases the value of the permissible braking pressure difference (.DELTA.P) as the frictional value of the road, the load of the vehicle, and the wheel base of the vehicle increase. The algorithm decreases the value of the permissible braking pressure difference (.DELTA.P) as the level of the center-of-gravity of the vehicle and the wheel gauge of the vehicle increase.
