Tire-road contact information for driver assistance systems: an optical sensor approach

摘要

An EC-funded Fricti@n project (2006-2008) developed sensor fusion technologies for friction potential estimation. In addition, tire sensors were studied in depth. A predecessor project of Fricti@n, the Apollo project,1 concentrated only on tire sensors and resulted in a special 3-in-l test tire. The tire possessed three different sensors: a MEMS (micro-electromechanical system) acceleration sensor, a piezoelectric strain sensor, and an optical position detection sensor. Since tire sensors had a minor role in the Fricti@n project, it seemed evident that there were no resources to develop all these sensor types further.
