CONTROL SYSTEM AND METHOD FOR SHIFT QUALITY AND PERFORMANCE IMPROVEMENT IN MANUAL TRANSMISSIONS USING ENGINE SPEED CONTROL

摘要

A control system for an engine of a vehicle includes a shift forecastingmodule that forecasts one of an upshift and a downshift of a manual transmissionbased on vehicle acceleration, clutch pedal position, acceleration pedal positionand brake pedal position. A gear state calculating module determines a currentgear state based on a speed of the engine and a speed of the vehicle. A nextgear state calculating module determines a next gear state. The next gear stateis based on the current gear state and the one of the upshift and downshift. Anext engine speed calculating module estimates an estimated engine speedbased on the next gear state and the vehicle speed. An engine speed controlmodule adjusts the engine speed based on the estimated engine speed.
