Methods and systems for engine control
Abstract:
Systems and methods are provided for restarting an engine that can be selectively deactivated during idle-stop conditions. In one embodiment, the engine is restarted with torque reduction over an interval of the restart, for example, by upshifting the transmission. In response to a vehicle launch request, the torque reduction is decreased, for example, by downshifting the transmission, to expedite return of driveline torque.
