Active motor vehicle spring system - regulates vehicle height position during anti-cross inclination steering

摘要

Pressure control appts. (20FL-20RR) are available to control the fluid pressure coming from a pressure source (16) to the admission equipment (18FL-18RR) of the suspension units (15FL-15RR) of the vehicle. Sensors (26) detect the cross acceleration (G) acting on the vehicle, emitting an appropriate signal. A control (30) responds to the signal from the sensors (26) in order to prepare a control signal for the pressure control appts. (20FL-20RR) which incorporates first and second pressure control signals. The first control signal controls the pressure control appts. in such a way that a first fluid pressure for suppression of cross inclination movement is made available, such movement being attributable to the cross acceleration acting on the vehicle bodywork (14). The second pressure control signal controls the pressure control appts. so that the second fluid pressure for adjustment of a predetermined vehicle height position is made available. The control appts. responds to an increase in cross acceleration detected by the sensors (26), in order to correct the second control signal and to reduce the second fluid pressure by a predetermined rate. ADVANTAGE - Suppression of cross inclination and rocking movements in motor vehicles by means of spring control system.
