Partial vehicle state estimation using Hight Order Sliding Mode Observers

Sometimes, the use of the global vehicle dynamic model is not needed to analyse and develop some applications in vehicle. For example, for the passenger comfort only the sub-model of the suspension is needed. In this context, this paper deals with a splitting of dynamic model for vehicle into five sub-models each one describing a subsystems regrouped in three blocks. The novelty of this idea consists in exploiting the splitting dynamic model of vehicle to develop a partial state observers. For the estimation we use the High Order Sliding Mode Observers. The simulation results are achieved by a car simulator.
