  • Patent number: 9944279
    Abstract: A control system for a hybrid vehicle configured to promptly shift a drive mode. In the single-motor mode, the vehicle is powered by a second motor while bringing an engagement device into disengagement and stopping the engine. In the dual-motor mode, the vehicle is powered by both a first motor and the second motor while bringing the engagement device into engagement and stopping a rotation of the output shaft of the engine by a stopper device. When shifting the drive mode from the single-motor mode to the dual-motor mode, the control system controls the first motor in a manner such that a speed difference between an input speed and an output speed of the engagement device is reduced while increasing a torque transmitting capacity of the engagement device.

  • Publication number: 20180065617
    Abstract: A control device for a hybrid vehicle includes a rotation detector and electronic control unit. The rotation detector is configured to detect a rotational state of the third rotational element of the hybrid vehicle. The electronic control unit is configured to control a first motor generator of the hybrid vehicle such that output torque of the first motor generator becomes zero when the electronic control unit determines, based on the rotational state of the third rotational element, that the third rotational element has a rotational fluctuation while the hybrid vehicle is travelling in a dual drive motor travelling mode. The dual drive motor travelling mode is a mode in which the hybrid vehicle travels while both the first motor generator and a second motor generator serve as driving force sources for travelling in a state where a first rotational element is fixed by a lock mechanism.
