This paper deals with an approach to estimate the road profile, by use of sliding mode observers. First, we present some results related to the validation of a full car modelization, by means of comparisons between simu lations results and experimental measurements (coming from a peugeot 406 test car). Then, we introduce the design of sliding mode observers for estimating the un known inputs which are the road profile variations acting on the four wheels.
