Signal generation system to loop or closed-loop control to open the open-loop or closed-loop control possible perspective

摘要

Using signals (Vi) representing the vertical motion of the vehicle body at selected points (Pi) on the body and second signals (Xarvl', Xarvr', Xarhl', Xarhr') representing the relative motion of the wheel units with respect to the body, the system proposed by the invention enables conclusions to be drawn concerning selected vehicle-body motion components, such as lift, roll and pitch, the vertical motion of the body at the front and rear axles, or the roll motion. These motion components are weighted differently. Using these differently weighted motion components, conclusions are drawn concerning second body motions at those points as which the wheel-suspension systems act on the body. By comparing the second body motions (Vagvl, Vagvr, Vaghl, Vaghr) with the associated relative motion of the wheel units with respect to the body, control signals are generated for the suspension system concerned in such a way that the selected motion components can be influenced independently of each other to give a reduction in motion.
