When a preview sensor 65 acquires undulation information regarding a convex portion of a road surface, an electric actuator 30 expands during a predetermined period of time between that point and a point immediately before the wheel rides on the convex por...

The axle suspension has a sensor unit with an oscillation sensor (21), with which an oscillation of a component of vehicle is detected and is transferred to a control unit (20). A control signal is generated in the control unit and is transmitted to a posi...

A method is described for operating a vehicle which includes a payload compartment and a first and second surface engaging devices as well as a suspension system. The suspension system has a first controllable suspension element for exerting a force betwee...

An active suspension is disclosed for us with a surface vehicle for operating along a path and which includes a payload and payload compartment. The active suspension has a controllable suspension element for modifying the displacement between the payload ...

An operating process for a motor vehicle (1) level regulation unit comprises sensing the distance between the body and wheel axles and adjusting this to an ideal value if given limits are exceeded by activating actuators to equalize the level horizontally....

An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system (24) for locating the vehicle, and a system for r...

Using dynamic portions of a vehicle's wheel motions and/or forces above a preset limiting frequency acting on the wheel produces an analysis for differentiating between types of roadway/roadway conditions. A wheel support for a wheel (14) spring-mounted ag...

An active suspension system for supporting a mass, such as a seat (12) on a base (16) of a vehicle, includes a hydraulic actuator (18) coupled between the seat (12) and the base (16), an pneumatic off-load device between the seat and the base (16), and a c...

An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system for locating the vehicle, and a system for retrie...
