Abstract

An automated clutch system for transferring torque from an engine to a change gear transmission is connected to a processing unit which uses various input parameters to calculate the grade on which the vehicle is operating and its current weight to determine an appropriate start gear to minimise clutch slip when the vehicle is launched from rest.
