IPC: F16H61/66
Filed: 2021-02-19
Abstract: To provide a vehicle drive apparatus capable of reducing a time required until a second travel mode is set after the second travel mode is requested.SOLUTION: In a vehicle drive apparatus, the other output shaft of a first output shaft and a second output shaft is connected to a third rotary element of a differential mechanism by a connection/disconnection mechanism in a connectable and disconnectable manner. A control device sets, as a travel mode, a first travel mode of using power from at least a first power source to cause a vehicle to travel, and a second travel mode of using power from a second power source to cause the vehicle to travel. The control device puts the connection/disconnection mechanism into a connection state when the first travel mode is set, and puts the connection/disconnection mechanism into a disconnection state when the second travel mode is set. When it is determined, during the traveling of the vehicle in the first travel mode, that there is a high possibility of switching from the first travel mode to the second travel mode, the control device switches the connection/disconnection mechanism from the connection state to the disconnection state.SELECTED DRAWING: Figure 16
