  • Patent number: 9688132
    Abstract: A hybrid vehicle uses a first motor, a second motor and an engine as driving force sources and includes a gear transmission mechanism and an oil supply mechanism. The gear transmission mechanism transmits torque, output from the first motor, to a drive shaft side. The oil supply mechanism is driven by power other than power of the engine to supply oil to the gear transmission mechanism. When the hybrid vehicle is caused to travel by using the torque output from at least the first motor in a state where operation of the engine is stopped, and when an estimated amount of oil that is supplied from the oil supply mechanism to the gear transmission mechanism is smaller than or equal to a predetermined amount, an electronic control unit limits an operation state of the first motor such that load on the gear transmission mechanism decreases.

  • Patent number: 9683659
    Abstract: When an alternator load torque Talt is larger than a threshold ?, a lockup clutch is released. Thus, a deceleration G can be restrained from becoming too large due to the alternator load torque Talt. Besides, the threshold ? is changed in accordance with a speed ratio ? of a continuously variable transmission. Thus, the deceleration G can be favorably controlled within a predetermined range. For example, in a vehicle state where a deceleration is unlikely to be achieved due to the smallness of the speed ratio ?, the threshold ? is large. Therefore, the lockup clutch is unlikely to be released, and the deceleration G is likely to be secured.
