Abstract:
1. A hybrid vehicle, comprising: an engine having a crankshaft; an electric machine that selectively drives said crankshaft; and a control module that deactivates cylinders of said engine, that induces said electric machine to drive said crankshaft, that determines a target crankshaft position when a rotational speed of said crankshaft crosses a first threshold, that induces said electric machine to drive said crankshaft towards said target crankshaft position at a nudge rotational speed, that induces said electric machine to brake rotation of said crankshaft when a brake crankshaft position is achieved at said nudge rotational speed and that induces said electric machine to arrest rotation of said crankshaft at said target position, wherein said control module determines respective rotational speeds of said crankshaft and said electric machine, and relaxes a throttle actuator of said internal combustion engine when said respective rotational speeds each equal zero.
