Abstract

An apparatus and method for controlling the operation of a clutch (12) in a partially or fully automated mechanical transmission (13) which is responsive to the actual load on the vehicle engine (11) for varying the engagement rate of release bearing (33) during re-engagement of the clutch (12). The apparatus includes an electronic controller (20) which initially sets a desired speed for the vehicle engine (11) during the shifting process, determines a rate of engagement movement of a release bearing (33) of the clutch (12), and actuates appropriate valves (41, 44) to initiate the gradual engagement of the clutch (12). The electronic controller (20) sets a first lower engine speed threshold and a second lower engine speed threshold. The magnitude of the first lower engine speed threshold varies with the actual load on the engine (11) or with both the actual load on the engine (11) and the amount of depression of an accelerator pedal of the vehicle.
