  • active suspension means for generating a downward normal force on each of the wheels, said active suspension means comprising a plurality of actuator means each coupled to one of the wheels and each responsive to a command signal for generating said downward normal force;

    detection means for generating a slippage signal when any of the wheels slips beyond a desired value; and

    suspension control means for generating said command signal in response to said slippage signal and for applying said command signal to each of said plurality of actuator means thereby increasing both the normal force and lateral force applied to all the wheels.
