摘要： A vehicle driving apparatus includes: an engine; a fluid transmission device; first and second rotary electric machines; an output shaft for receiving a power transmitted through a first power transmission path and outputting the power to one of a pair of front wheels and a pair of rear wheels; and a control device for controlling an engine operation point by adjusting an electrical path amount between the first and second rotary electric machines. The second rotary electric machine outputs the power to the other of the pair of front wheels and the pair of rear wheels, through a second power transmission path. The control device obtains a target electrical path amount enabling the engine operation point to become a target operation point, and causes a speed change device provided in the second power transmission path to establish a gear ratio enabling the target electrical path amount to be attainable.

摘要： It is determined whether fuel efficiency of a vehicle is improved by operating a first rotating machine to generate electricity to such an extent that an electrical path amount becomes a desired electrical path amount for controlling an operating point of an engine to a desired operating point and driving and operating a second rotating machine as a second power source, the electrical path amount being a magnitude of electric power in an electrical path through which the electric power is transferred between the first rotating machine and the second rotating machine. When the electronic control device determines that the fuel efficiency of the vehicle is improved, the first rotating machine is operated to generate electricity to such an extent that the electrical path amount becomes the desired electrical path amount and the second rotating machine is driven and operated as the second power source.

摘要： In a vehicle drive device, a second power source is connected to a first rotating element of a differential mechanism, and the other output shaft of a first output shaft and a second output shaft is connected to a third rotating element so as to be disconnectable and connectable by a disconnection-connection mechanism. A control device places the disconnection-connection mechanism in a disconnected state. When a second traveling mode in which the third rotating element is fixed to a fixing member through engagement of an engaging element is switched to a first traveling mode in which the disconnection-connection mechanism is placed in a connected state, the control device disengages the engaging element, executes synchronous control in which rotational speeds of the other output shaft and the third rotating element are synchronized by a second power source, and switches the disconnection-connection mechanism from the disconnected state to the connected state.

摘要： When temperature of a second power source of a vehicle becomes higher than a threshold value during a first mode in which three rotating elements of a differential gear can make differential movement and when four-wheel drive is needed, switching is performed to a second mode in which the three rotating elements are unified, and when four-wheel drive is not needed even when the temperature of the second power source becomes higher than the threshold value during the first mode, output of the second power source is restricted, while the first mode is maintained.
