Engine throttle control for improved shifting |
摘要 |
A vehicle includes a powershift transmission driven by an electronically controlled engine. A control system momentarily modifies a magnitude of an engine throttle command signal during a shift of the power shift transmission in order to make the shift smoother and less sensitive to achieving optimum clutch engagement pressure. It also prevents an engine governor from over-reacting and causing rough shifts.
