PROBLEM TO BE SOLVED: To rapidly synchronize input rotation speed and output rotation speed of a clutch.SOLUTION: An engine is connected to an input side of a continuously variable transmission, and an electric motor is connected to an output side of the continuously variable transmission via the clutch. Further, a driving wheel is connected to the electric motor. When the clutch is switched to an engaged state for switching from an EV mode to an HEV mode, rotation speed control of the engine and shift control of the continuously variable transmission are performed, and the input rotation speed is increased toward the output rotation speed interlocked with vehicle speed. In the synchronization control, the engine is controlled with maximum output torque toward fixed target rotation speed TNe2. Further, the continuously variable transmission is upshifted at maximum shift speed so as to cancel rotation speed difference between input rotation speed Nci and output rotation speed Nco. Thereby, the input rotation speed Nci can be increased quickly, and the input rotation speed Nci and the output rotation speed Nco can be synchronized quickly. |
