— This paper presents a new robust observer methodology based on sliding mode for estimation of vehicle velocity. The paper addresses the design and implementation issues of such observer which is based on the measurement by a standard sensor in many of the new cars. This is the encoders which are mounted in the ABS system. They provide a low angular resolution position measurement. The estimate has been validated experimentally using an instrumented vehicle by different sensors. The actual results show effectiveness and robustness of the proposed method
