Crankshaft stop positioning control system |
摘要 |
A method of regulating a crankshaft position in a hybrid electric vehicle includes deactivating cylinders of an internal combustion engine, driving a crankshaft of the internal combustion engine using an electric machine, and determining a target crankshaft position when a rotational speed of the crankshaft crosses a first threshold. The crankshaft is driven towards the target crankshaft position at a nudge rotational speed, and rotation of the crankshaft is braked using the electric machine when a brake crankshaft position is achieved at the target rotational speed. Rotation of the crankshaft is arrested at the target position.
