A new low cost integration of force and moment measurements into a wheel bearing is proposed. Those data will enhance performances of existing driving assistance systems and enable emergence of new ones. The measurement principle stems from the dependancy between the contact forces transmitted by the balls and the force components to be measured. The deformations caused by the contact forces come...
This paper presents a sliding mode observer of vehicle sideslip angle, which is the principal variable relating to the transversal forces at the tire/road interface. The vehicle is first modelled, and the model is subsequently simplified. This study validates the observer using both a validated simulator and real experimental data acquired by the Heudiasyc laboratory car, and also shows the limitations...
Transversal tire forces and sideslip angle are essential data for improving vehicle safety, handling, steerability, comfort and performance. This paper proposes and compares four observers designed to calculate vehicle sideslip angle and lateral tire forces. The different observers are derived from the extended Kalman filter (EKF), the single-track model, and use different on tire-force models. The...
