Abstract
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.
