  • Hybrid vehicle system
    Patent number: 6884199
    Abstract: This system comprises an engine 1, a transmission device 4, a clutch 3 for engaging/disengaging the engine 1 with/from the transmission device 4, a rotational electric device 2, a power transmission mechanism 5 for inputting the rotation of the rotational electric device 2 to the transmission device, and an accumulator element 7 for accumulating electrical power supplied by the rotational electric device 2. A control unit 20 determines a gear change instruction for the transmission device 4, and if gear change instruction is determined, it disengages the clutch 3, and controls the rotation of the rotational electric device 2 in such a manner that the rotational speed of the input shaft of the transmission device becomes a target rotational speed required for a gear changing operation.
