1. A control system for stabilizing the rolling of the vehicle body, comprising:

  • control elements operatively arranged between the wheels and the vehicle body to generate forces approximately in a vertical direction with respect to the vehicle body to cause a rolling moment at the vehicle body which counteracts rolling motions acting on the vehicle body on response to driving conditions; and

    means for selectively actuating the control system only when threshold values of the vehicle lateral acceleration and of the vehicle steering-wheel turning angle are exceeded such that a magnitude of the rolling moment generated by the control elements, as a function of a first set of parameters comprising the approximately vertical wheel distances to the vehicle body, is at first substantially formed at the rear axle and, after actuation and during a transition period whose time length is determined as a function of a second set of parameters independently of the first set of parameters, the rolling moment distribution between the front-wheel and the rear-wheel axle is changed to a given fixed rolling moment distribution between the front-wheel axle and the rear-wheel axle at the end of the transition period.
