Abstract

The friction clutch (3) is operated by a servo drive (15) via a processor control (17). This operates th clutch w.r.t the engine condition and the vehicle speed etc.. The control has two reference engine speeds; one below idling speed and one above. the lower level is used to release the clutch to prevent stalling while the higher level is used as an engine braking control e.g. on inclines. The higher speed can be used to provide controlled engine braking if the vehicle rolls against the set gear direction, with the throttle pedal at idling. This allows the driver to move the vehicle in and out of spaces on an incline with a minimum of gear changes. The lower reference speed is 100 to 300 rpm below normal idling speed while the higher level is 50 to 500 rpm above idling. The exact levels are determined w.r.t engine/vehicle conditions. ADVANTAGE - Improved drive control, less risk of engine stalling.
