  • Controllable wheel suspension system for an active running gear of a motor vehicle
    Patent number: 6293561
    Abstract: A regulatable suspension system for an active chassis of a motor vehicle has at least two actuators which are capable of being set via actuating signals in order to influence the relative movement between a wheel of the motor vehicle and the vehicle body. A control unit is provided for generating the actuating signals as a function of input signals representing vehicle state variables. Actuating movements that can be applied to the wheel by the actuators and acting on the wheel have parallel direction components. In the event of a fault, if one actuator is defective, actuating signals coupling the actuators can be generated in such a way that a control function assigned to the defective actuator can be set via an intact actuator.
