Abstract:
In a vehicle driving apparatus including a differential mechanism capable of executing a differential action, a control device can make the driving apparatus small-size, improve fuel consumption, and increase output torque. A transmission mechanism can be switched to a continuously variable shifting state and a step variable shifting state, by a switching clutch or a switching brake. Also, with a switch control bringing the switching clutch into a half-engaged state, during an engine startup/running, while the differential portion is allowed to operate as the electrically controlled continuously variable transmission, a reaction force against an engine torque is generated by the half-engaged switching clutch. Thus, the engine torque not less than the torque bearable by a first electric motor can be inputted into the differential portion, thereby increasing the output torque.
