ABSTRACT:
The invention relates to a control system for a vehicle with wheels, where at least one wheel is connected with means for braking and/or driving the wheel, the control system comprising a measuring device to measure a rotational speed of the wheel, a longitudinal force and a vertical force that occur at the wheel-road contact, and a control unit connected to the measuring device, to control the braking and/or driving of the wheel. The system is equipped to determine the second derivative (SD) of the wheel speed to the quotient of the longitudinal force and the vertical force and use this parameter to control the braking and/or driving the wheel.
