  • Patent number: 6190282
    Abstract: The present invention is proposed to avoid the generation of shocks when the output of an engine is switched with that of an electric motor connected by a clutch. The invention comprises a first electric motor connected mechanically to an engine and a second electrical motor connected mechanically through a clutch to an engine. The drive force is transmitted to the drive wheel through a transmission from the second electric motor. It is decided whether or not to connect the clutch on the basis of driving conditions. When it is decided to connect the clutch, the engine is controlled so that the output of the engine meets the required force. The first electric motor functions as an electric generator so that the rotation speed of the engine reaches a target rotation speed. When the engine is rotating at a target rotation speed, the clutch is connected. In this way, shocks are avoided when the clutch is connected and improved driving performance is realized.

  • Patent number: 5993351
    Abstract: A shock when switching between the motive force of a motor and an engine is avoided. A first electrical motor mechanically connected to an engine and a second electrical motor connected mechanically to an engine through a clutch is provided. In a hybrid vehicle in which motive force is transmitted to the drive wheels through a transmission from a second electric motor, it is decided whether or not to release the clutch based on the vehicle speed detected value and the required motive force detected value. The engine output at that time is estimated. Thus if it is decided to release the clutch, the output of the second electrical motor is controlled so that the generated torque corresponds to said estimated output. The output of the first electrical motor is controlled so that the torque generated by the second electrical motor is absorbed. Hence the sum of both outputs is approximately 0.
