ABSTRACT:
A control method/system for controlling engine fueling during vehicle launch conditions for a vehicle equipped with an automated mechanical transmission system (10) including a fuel-controlled engine (14), a master friction clutch (16), a multiple-speed mechanical transmission (12) and a microprocessor-based control unit (44). During vehicle launch, if throttle position (THL) is less than a reference value (10-20% of maximum fueling), fueling is according to throttle position; otherwise, fueling is a calculated amount (F.sub.CALC) determined by the control unit as a function of throttle position, engine speed (ES) and/or the rate of change (dES/dt) thereof, clutch condition and/or time factors.
