  • Patent number: 7832738
    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.

  • Patent number: 7063333
    Abstract: In a method and a device of a motor vehicle, including regulating units for adjusting the level position of a motor vehicle, at least one control unit for activating the regulating units, at least one sensor mechanism for recording the actual level position of the motor vehicle and a device for setting a setpoint level position of the motor vehicle, the actual level position being adapted to the actual speed of the motor vehicle regarding driving dynamics, whereby a set setpoint level position is able to be fixed, a limiting speed Vlimit regarding driving dynamics is able to be assigned to the setpoint level position, and this limiting speed is not able to be exceeded.
