Abstract

To prevent a motor vehicles engine being forced over its speed limit as a result of erroneous selection of a too low a gear during gear changing while still providing engine braking, a clutch between engine and gearbox is caused to slip. The clutch, mounted between the engine and a gearbox, is automatically engaged/disengaged by a setting member controlled by a micro-controller which immediately disengages the clutch when a gear shift lever is operated. Upon engaging a new gear, synchronization commences during which the gearbox speed is monitored so that if a predetermined speed threshold is exceeded the disengaged clutch is engaged with a predetermined adjustment speed up to its engagement point. The amount of engagement, beyond the initial engagement point is continuously adjusted by altering the ideal clutch stroke, which is continuously calculated by using an algorithm, until the speed does not exceed the predetermined speed threshold.
