摘要: A control device of a vehicle is configured to select motor running by one motor, motor running by two motors, and engine running. A charging capacity of an electric storage device allowing selection of the motor running by two motors is higher than a charging capacity allowing selection of the motor running by one motor. In the motor running by two motors and the engine running, a drive force larger than in the motor running by one motor is generated. When the motor running by one motor is performed with a charging capacity equal to or greater than a first threshold value, and a driver's drive request amount is increased, if the charging capacity is equal to or greater than a second threshold value higher than the first threshold value, the motor running by two motors is selected, while if the charging capacity is less than the second threshold value, the engine running is selected.

摘要: When an engine stop control is executed while an automatic ratio shift portion is in a neutral state, a switching clutch is operated, so that a differential portion carrier of a differential portion planetary gear device that is linked to an engine, and a differential portion ring gear linked the automatic ratio shift portion are integrally rotated. Therefore, along with the engine stop control, the rotation speed of the rotating elements of the differential portion planetary gear device is reduced while the rotating elements are integrally rotated or substantially integrally rotated. Since the rotating elements are rotated integrally or substantially integrally, the high rotation speed of the differential portion ring gear linked to the automatic ratio shift portion, which tends to have a heightened rotation speed particularly during the neutral state, is prevented.

摘要: When an engine is driven on a different type of fuel (for example, ethanol-containing fuel) from a reference fuel (for example, gasoline) and the engine torque is thus greater than that produced when the engine is driven on the reference fuel, a differential state control device expands a non-differential range compared to that at the time when the reference fuel is used. Thus, in the case where a plurality of types of fuel including the reference fuel are supplied to the engine, the advantage of switching a power distribution mechanism between a differential enabled state and a non-differential state can be fully utilized in correspondence with engine torque characteristics which may vary in accordance with the type of fuel for the engine. As a result, the fuel consumption rate can be reduced in correspondence with the plurality of types of fuel supplied to the engine, for example.

摘要: When a reduction in a supply hydraulic pressure to a second shift portion is sensed, an engagement command of C0 clutch is generated so that a power split device (electrical differential portion) is brought into a locked state. In the locked state, a sun gear, a carrier rotated by an engine and a ring gear rotated by a second MG integrally rotate, whereby inertia is increased. Thus, high-speed rotation of a transmission member corresponding to an input shaft of the second shift portion can be prevented.
