<p>A control is provided for controlling reengagement of a master clutch (16) in a vehicular automated mechanical transmission system. A nominal reengagement rate (CLU_RATE) is determined as a function of engine lag (K1), throttle position (THL), engine acceleration/deceleration (dES/dt) and/or input shaft acceleration/deceleration (dIS/dt). 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.</p> |
