Abstract
A process is disclosed for adjusting the speed of a vehicle travelling on a gradient to a predetermined desired speed, wherein the vehicle is equipped with an ABS and/or ASR system, comprises determining the actual speed of the vehicle travelling on a gradient, determining a control deviation for the vehicle, the control deviation being the difference between the actual speed of the vehicle and the desired speed, and actively applying the brakes of the vehicle when the control deviation is greater than a predetermined amount. Only the brakes of the downhill axle are braked so long as the control deviation is less than a predetermined control deviation, or so long as the slip of the braked wheels are less than a predetermined slip. The brakes of the uphill axle are applied only if the predetermined control deviation is exceeded.
