ABSTRACT:
A method for operating active stabilizers in a motor vehicle includes an on-road mode and an off-road mode. In the on-road mode a stabilizer is activated and deactivated in dependence on operating parameters of the motor vehicle, in particular the travel speed and/or the lateral acceleration and/or a level sensor system, wherein in the activated state rolling motions of the vehicle are reduced by introducing torque into the stabilizer or stabilizers that counteracts the rolling motion. In the off-road mode, the stabilizer is deactivated up to a given travel speed or, in case of an alternate jouncing of the wheels, a control of the stabilizer is performed such that a downward force of the rebounding wheel is increased. Wheel slip may be used as a parameter when controlling the stabilizers. A motor vehicle having active stabilizers is also provided.
