Abstract (en)

[origin: WO2020239440A1] The invention relates to an electronically open-loop or closed-loop controlled air spring system (100), in particular for an air spring system for height regulation (HR) of a vehicle (150), inter alia having: - a number of air springs (110), and - a number of switching valves (130) designed for height regulation (HR) of the vehicle (150) by means of an air spring (110.1) of the number of air springs (110). According to the invention, - at least one switching valve (SV), in particular a bellows valve (130.B) and/or a reservoir valve (130.R) and/or a ventilation valve (130.E), of the number of switching valves (130) is controllable, wherein - the lifting speed (UH) and/or the lowering speed (US) of the height regulation (HR) is adjusted by means of an open/closed parameter (AZP), preferably malleably, as an open portion (ATA) of the opened valve state (A) and/or a closed portion (ATZ) of the closed valve state (Z) at a switching period (P), and - the height regulation (HR) of the vehicle (150) preferably occurs from the reservoir (120).
