Abstract
A control for a vehicle drive line system (10) including an automated vehicle master clutch (14) drivingly interposed in between a fuel-controlled engine (12) and the input shaft (20) of a mechanical transmission. At sensed idle conditions (THL<REF and OS<REF), the engine (12) is commanded to generate an output torque (T.sub.FW) equal to a selected idle drive torque (T.sub.IDLE) at idle speed (ES=IDLE), the engine is commanded to rotate at idle speed and the clutch, preferably a wet clutch, is caused to engage with a torque capacity equal to the idle drive torque.
