摘要:
The invention relates to a method for actuating an active suspension of a two-axle two-track motor vehicle, wherein forces directed opposite a roll of the vehicle superstructure either at the wheels of the rear axle or at the wheels of the front axis and oriented in the vertical direction can be directed into the wheel suspension between each wheel and the superstructure by means of at least one suitable actuator. Additionally, in order to achieve the goal of limiting the roll angle, a control with regard to the transverse dynamics is input into the actuation of the actuator, in addition to a servo-control with regard to the transverse dynamics of the vehicle. By suitably actuating the actuator as a function of the transverse acceleration currently acting on the vehicle in the sense of a transverse dynamic servo-control, a roll angle is preferably permitted or set, said angle optionally being derived substantially from a so-called friction-independent roll characteristic curve for neutral characteristic roll performance under consideration of an additional roll angle having a low magnitude and generating a slightly understeered driving performance, said angle providing the magnitude of a so-called neutral roll angle for each potential transverse acceleration, by means of which the vehicle performs neutrally, that is, neither oversteered nor significantly understeered.
