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