In a hybrid vehicle, a motor/generator and an engine are connected to an input shaft of a continuously variable transmission, and an output shaft of the continuously variable transmission is connected to the drive wheels of the vehicle. A power transmission mechanism having a predetermined input/output rotation ratio is interposed between the motor/generator and input shaft. By presetting this input/output rotation ratio to cancel the difference between the high efficiency rotation speed region of the motor/generator and the rotation speed region of the engine, it becomes unnecessary to change the drive ratio of the continuously variable transmission even when the source of drive force is a changed over from the motor/generator to the engine, or vice versa. <IMAGE> |
