Harmonised methods for brake testing on heavy commercial vehicles
free download

A large proportion of heavy vehicles brakes fail to pass the yearly vehicle tests. The vehicle testing methods used in periodic technical inspections should be improved in order to make tests more repeatable and improve assessment of the technical condition of brakes. In orderThe automotive industry takes part in an exciting development of technical innovations coming along with digitalization and increasing computing power. Thereby the innovation cycles are shortening continuously and are creating new opportunities. In the last decade
