  • 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.

  • Patent number: 9464687
    Abstract: A continuously variable transmission belt includes rings each superimposing annular component pieces on each other's inner and outer peripheries, and plural elements attached to the rings side by side in a circumferential direction. Each element includes a neck portion. The rings are disposed on opposite sides of the neck portion. The elements contact a driving pulley and a driven pulley. A lubrication oil discharge mechanism discharges out a lubrication oil in at least one of a gap between the component pieces, and a gap between each ring and the elements. A function of discharging the lubrication oil present in a region remote from the neck portion is higher than a function of discharging the lubrication oil present in a region near the neck portion. Thereby, the rings to which the elements are attached or the component pieces of the rings restrain decline in the centering characteristic in the width direction.
