PROBLEM TO BE SOLVED: To accomplish assurance of driving force and improvement of recovering efficiency of power energy by two motors having a comparatively low power output, realize optimization of control of an engine and the motors for demanded driving force from drive wheels, reduce mutual an influence of control of the engine and the two motors, simplify its control, and improve control degrees of freedom. SOLUTION: An output shaft 1a of an engine 1 is connected to a sun gear 2a, a motor 3 is connected to a flywheel starter gear 2b, and a motor 4 and a CVT 5a are connected to a carrier 2c. At the time of driving, the engine 1 and the motors 3, 4 are used as a driving source, or the engine 1 and the motor 3 are used as the driving source and the motor 4 is used as a power generator, or only motor 4 is used as the power generator, and at the time of braking, the motor 3 is used as the driving source and the motor 4 is used as the power generator, or only the motor 4 is used the power generator so as to carry out various control. Thereby, driving force is ensured and recovering efficiency of power energy is improved by the motors 3, 4 having a comparatively low power output. Further, an influence of the engine 1 and the motors 3, 4 are reduced, and simple and optimal control having degrees of freedom can be realized. |
