Research on Running Attitude Control of Full Vehicle With Magnetorheological Suspensions and Road Test
Based on building a vibration model of full vehicle with magneto-rheological(MR)suspension,to restrain vehicle vertical vibration and pitch motion,and improve wheel road holding capability,a hierarchical attitude control system is proposed.It includes direct control level and parameter correction level.In control level,various characteristic model of vehicle vibration is given and corresponding control strategy is proposed.In parameter correction level,according to vehicle running attitude and characteristics of MR suspensions vibration in different conditions,several parameters of control level are modified.A test and control system is set up and implemented on an automotive vehicle equipped with four MR dampers.Road tests under various conditions were carried out.Test results indicate that the hierarchical attitude controller can effectively reduce vertical vibration,pitch motion and wheel vibration of automotive vehicle equipped with MR suspensions,improve ride comfort and handling stability.
