A stabilizer assembly unit for a motor vehicle, having a first fluid pressure actuator and a second fluid pressure actuator which are associated with opposite ends of an antiroll bar, characterized in that exactly one pressure fluid connection is provided on each of the fluid pressure actuators.

Stabilizer assembly unit for a motor vehicle

The invention relates to an active chassis stabilization system including a hydraulic pressure supply unit, a hydraulic stabilizer assembly which is associated with a front axle, a hydraulic stabilizer assembly which is associated with a rear axle, and a control unit. The active chassis stabilization system is a two-channel system.

Active chassis stabilization system

A hydraulic control system for high flow applications in motor vehicles, in particular for active wheel suspensions and active steering arrangements, includes at least one passive high flow valve which is controlled hydraulically by at least one low flow valve.

Hydraulic control system for high flow applications in motor vehicles

A steering system for a motor vehicle, including a steering gear and at least one tie rod, is characterized in that an actuator is provided, which can move an end section of the tie rod transversely to the direction in which the end section can be adjusted by the steering gear. A method of controlling a vehicle, in which steerable wheels of a vehicle are acted upon, is characterized in that a correction steering angle is superimposed on a steering angle of the steerable wheels which is given by a steering gear, which correction steering angle is brought about by an actuator which acts on one of the steerable wheels.

Steering system and a method for controlling a vehicle

An assembly including a fluid pressure actuator, which has a guide part and an active part movable relative thereto, and a fluid pressure source which is in communication with the fluid pressure actuator in order to supply the latter with fluid which is under pressure, is characterized in that a locking device is provided which can interrupt the connection of the fluid pressure actuator with the fluid pressure source, that a control unit is provided which controls the locking device, and that the fluid pressure actuator is provided with a sensor by means of which the control unit can determine the position of the active part relative to the guide part.

Assembly for a chassis stabilizing system

A method for operating a chassis regulating system of a vehicle, in which a control quantity is generated for an actuator, includes providing a first signal, which is representative of the transverse acceleration of the vehicle, providing a second signal, which is representative of the steering lock angle, providing a third signal, which is representative of the speed of the vehicle, allocating a weighting factor for the amplitude of the first signal, generating an estimated transverse acceleration signal from the second signal and the third signal, generating a weighted estimation signal by multiplying the estimated transverse acceleration signal with the weighting factor, and generating the control quantity by additive superimposing of the weighted estimation signal with the first signal.

Method for operating a chassis regulating system and a device to carry out the method

A stabilizer assembly for a motor vehicle, including a first stabilizer and a second stabilizer, which are rotatable relative to each other, is characterized in that each stabilizer is engaged by one linear actuator each.

Stabilizer assembly for a motor vehicle

A method and apparatus for detecting and compensating for wheel brake irregularities includes a unit for detecting a control signal that controls a brake actuator, a unit for detecting changes of the control signal generated by the actuator, and a unit for evaluating control signal changes. The frequency and amplitude of such changes are analyzed to detect the existence of a brake irregularity.
