US 6,293,561 B1 · Controllable wheel suspension system for an active running gear of a motor vehicle

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.

Dependent claims

A regulatable suspension system for an active chassis of a motor vehicle, comprising:

at least two actuators for controlling relative movement between a wheel of the motor vehicle and a vehicle body;
and
a control unit for generating actuating signals for setting actuating movements of said actuators as a function of input signals representing vehicle state variables;
wherein
actuating movements which can be generated by the at least two actuators, acting on the wheel, have parallel direction components;
and
in the event of a failure of one actuator, actuating signals coupling the actuators can be generated to control a degree of freedom previously controlled by the failed actuator, via an intact actuator.
