Patent number: 7013206Abstract: One or several vibration dampers of a vehicle suspension have a damping force arrangement wherein a control signal is computed within the actuating range in accordance with a standard control method for adjusting the damper characteristic. The drive of a damper adjustable in accordance with this invention is so improved that body movements (notwithstanding a harder adjusted damping for critical driving situations) are substantially suppressed as early as possible. In specific driving situations, the adjusting range of the damper force is changed in that the upper limit of the adjusting range is raised or lowered and/or the lower limit of the adjusting range is raised or lowered. A soft damper setting takes place preferably in dependence upon signals which announce or display a change of the vehicle longitudinal deceleration or vehicle transverse acceleration.Type: GrantFiled: September 2, 2003Date of Patent: March 14, 2006Assignees: Continental Aktiengesellschaft, ZF Sachs AGInventors: Alexander Stiller, Stefan Sommer, Jörg Grotendorst, Eberhard Hees, Thomas Kutsche, Wolfgang Schumacher, Christian Maurischat
