Abstract
A control is provided for controlling reengagement of a master clutch (16) in a vehicular automated mechanical transmission system. A nominal reengagement rate (CLU.sub.-- RATE) is determined as a function of engine lag (K.sub.1), throttle position (THL), engine acceleration/deceleration (dES/dt) and/or input shaft acceleration/deceleration (dIS/dr). To provide smoother shifting during braking (BRK=1, THL=0) and/or coasting (THL<30%) downshifts, the clutch is reengaged at a rate slower than the nominal reengagement rate.
