摘要

A variable power drivetrain engine control system for a heavy duty vehicle (10) which provides higher output capability for the engine of the vehicle (10) in accordance with certain detected conditions. If the vehicle speed (14) falls a predetermined DELTA miles/hour below a LEARNED SPEED (14a) of the vehicle, the engine is enabled to operate at a higher power output capability until the vehicle (10) resumes the LEARNED SPEED (14a). Further, high output capability is enabled when the vehicle decelerations (14e) is in excess of a predetermined deceleration rate. Again, the high output capability is disabled once the vehicle retains the LEARNED SPEED (14a) velocity. The quantity DELTA can be variable with respect to actual vehicle speed (14) to provide more responsive operation of the variable power drivetrain system thereby providing improved responsiveness to road conditions in accordance with relative vehicle speed (14).
