Control system responsive to relation between friction coefficient and wheel rotational speed for a wheel
Résumé
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 compris
ing 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 param
eter to control the braking and/or driving the Wheel.
