Abstract

This paper considers the design of Kalman filter observers for the on-line estimation of dynamic states of a vehicle suspension, with a view to applying semi-active suspension control. A data based identification method is presented, and two sources of data are considered; from vehicle tests on a four poster hydraulic shake rig, and also from quarter vehicle simulations. Both are subjected to a `full factorial' statistical study, and detailed conclusions are drawn concerning the relative importance of various operational parameters, in particular the type and location of feedback sensors. Finally, a `minimal' Kalman filter is designed which uses wheel hub and vehicle body mounted accelerometers alone; the resulting accuracy of state estimation is considered to be acceptable for semi-active suspension control.
