In this work, a new method is developed to estimate the unknown inputs of heavy vehicles. These inputs represent road profile which is very interesting since is used to estimate the vertical forces acting on the wheels. We reconstruct these unknown inputs by using higher order sliding mode observer. First, we estimate speeds and accelerations of heavy vehicle in finite time. Validation process is done using an instrumented heavy vehicle and measured road profile by LPA instrument.
