This chapter outlines some of the fundamental concepts of the lateral tire force. First, a survey of existing methods dealing with parameters that describes the lateral tire force is presented. Then, the chapter presents the original method for estimating individual lateral tire force and sideslip angle. The developed observers are derived from a simplified four‐wheel vehicle model, linear/nonlinear tire models and potentially available measurements. The estimation techniques are based on extended and unscented Kalman filtering techniques. Tire‐road interaction is represented by a relaxation model involving a linear and a quasi‐static Dugoff’s tire model. Experimental data acquired on both dry and wet pavements confirm that the proposed algorithm performs reliably in a number of different maneuvers. In the future, the improvement of the vehicle/road model will be valuable to widen validity domains of the observer, and make it adaptive to road conditions.
