Abstract

A clutch control system senses the speed of an engine, the speed of a transmission input shaft and computes a freewheel speed of the engine from the engine speed and throttle flap or accelerator pedal position, and also computes a corrected input shaft speed. The clutch is disengaged of the freewheel speed falls below the corrected input shaft speed and is engaged if the engine speed exceeds the corrected input shaftspeed. Alternatively uncorrected versions of the engine speed and input shaft speeds may be used with additional error correction consequent upon temporary changes in the engine speed and input speed. <IMAGE>
