Abstract
An automotive transmission transitions from a drive gear to a neutral gear when an engine is shutdown. During a rolling pull-up, a crankshaft of the engine will be spun up to a desired speed and the transmission will transition from the neutral gear to an appropriate gear based on a shift schedule. A target transmission input speed is commanded to be a synchronous speed plus an offset to smoothly transition out of electric axle drive propulsion.
