Abstract

A control system controls a gearbox connected to a combustion engine which powers a motor vehicle. It first determines whether there is or will soon be a situation of low power requirement for running the vehicle. In such a situation, the gearbox is switched to a high-ratio gear with - high transmission ratio so that the vehicle runs at an engine speed which is below the torque plateau for the high-ratio gear. This results in reduced fuel consumption.
