Abstract
A clutch mechanism is configured to selectively change between a first power transmission path and a second power transmission path. The first power transmission path is configured to transmit torque to an output shaft via a transmission mechanism. The second power transmission path is configured to transmit the torque to the output shaft via a continuously variable transmission mechanism. An electronic control unit is configured to: (a) selectively change a power transmission path during traveling to one of the first power transmission path and the second power transmission path by controlling the clutch mechanism; and (b) in changing the power transmission path by controlling the clutch mechanism, control an operating point of the internal combustion engine during a change of the power transmission path so that the operating point crosses over an optimum fuel, consumption line of the internal combustion engine.
