The knowledge of the friction coefficient between road and tyres is a very precious information to implement vehicle active control, especially considering the optimisation of the braking action. One of the most important parameters able to influence such a coefficient is the road texture (microtexture and macrotexture). Although different methods are now available to perform reliable texture measurements, no well-established techniques currently exist for measuring the pavement texture at medium-high speed with real time data analysis during the usual vehicle operations. This paper presents a method, based on two identical industrial laser-triangulation displacement transducers, allowing to get real time reliable road micro and macrotexture measurements during standard vehicle operations, even at medium and high speed. The presence of two transducers also allows to estimate the instantaneous vehicle speed …
