    摘要: In a method for semiactive chassis control, in particular for damping resilient wheel suspension systems in vehicles, having a piston displaceable in a cylinder and subdividing it into two work chambers, the cylinder and piston are each connected to a vehicle body or a wheel axle. At least one valve that controls the flow of pressure fluid into and out of the work chambers is associated with the work chambers. Control of the valve is effected as a function of an absolute vertical speed of the vehicle body and of a zero crossover of the relative speed of the relative motion between the axle or wheel in the vehicle body and/or of a zero crossover of the damper force and/or of a zero crossover of the differential pressure at the damper piston.

    摘要: In a system for controlling a chassis, in particular for controlling spring cylinders that can simultaneously perform the function of a semiactive shock absorber and are disposed between wheel suspensions and the vehicle body, at least one chamber of the spring cylinder is intended to communicate via a line or branch line with a pumping device, reservoir or the like for a pressure fluid, and at least one control member is connected between the pump device, reservoir or the like and the chamber. A control valve, which responds to a change in pressure in a shunt between the control valve and a line, is disposed in the control member.

    摘要: A system for the generation of signals for control or regulation of a passenger car and/or truck undercarriage controllable or regulable in its sequences of movement, where a three-step operation is provided. In a safety mode, particular allowance is made for road safety, and in a comfort mode for travel comfort. Moreover, a predetermined undercarriage setting is selected in a standard mode. These selections are based on the movements determined between the wheels and the vehicle superstructure, such as spring deflection movements. Furthermore, based on the determined spring deflection movements, the actual value P of the wheel load fluctuations and the movements of the vehicle superstructure are inventionally determined. By query of certain criteria it is determined whether the undercarriage, controllable or regulable in its sequences of movement, will be adjusted in view of minimizing the wheel load fluctuations (safety mode) or in view of minimizing the superstructure movements (comfort mode) or whether a predetermined, specifically soft undercarriage setting will be selected (standard mode).

    摘要: Basing on signals (Vi) representing the vertical movements of the vehicle body at selected points (Pi) of the body, and basing on second signals (Xarvl', Xarvr', Xarhl', Xarhr') representing the relative movements between the wheel units and the body of the vehicle, the inventional system infers selected components of movement of the vehicle body, such as heave, roll and pitch movements or the vertical movement of the body at the front and rear axles as well as the roll movement. These components of movement are weighted differently. Basing on these differently weighted components of movement, second body movements are inferred at the points where the wheel suspension systems attach to the body. By comparison of the second body movements (Vagvl, Vagvr, Vaghl, Vaghr) to the pertaining relative movements between the wheel units and the body there are actuation signals formed for the respective suspension system, in a way such that the selected components of movement can be influenced separately from one another in the sense of a reduction.

    摘要: A system for changing the damping characteristics of shock absorbers, based on the signals (Xar'(t)) of the relative movements such as the spring deflection velocity, between the vehicle superstructure and wheels, additional signals (Xar"(t)), such as the spring deflection acceleration, are determined. The two signals are logical linked so that the control of a vehicle variable, such as the activation of adjustably designed shock absorbers, is carried out. This makes it possible to change the characteristic of the shock absorber in operating phases of low damping forces of the shock absorber. This feature optionally reduces noise at damping characteristic changes.
