Abstract :
Knowledge of the torque and the tire forces at each wheel is an important intermediate variable for system design of advanced driver assistance. This paper describes how it is possible to estimate online the torque and the longitudinal force of the vehicle wheel. We use a simplified model to synthesize the non-linear high-gain observer. The observer is validated on a comprehensive model of the vehicle. The necessary measurements is the usual rotation speed of wheel. Simulation results show effectiveness and robustness of the proposed method.
