PROBLEM TO BE SOLVED: To provide a method and an apparatus for controlling propeller driving capable of improving fuel efficiency by actuating a prime motor at a best fuel consumption amount point.SOLUTION: Rotation of a prime motor for a propeller is input to a planetary reducer via a main clutch (a first path), and to a variable capacity hydraulic pump (for a variable capacity hydraulic motor) via a hydraulic pump CVT (a second path). Power of the variable capacity hydraulic motor is input to the planetary reducer. Resultant power of a combination of the power of the prime motor input to the "planetary reducer" and the power of the variable capacity hydraulic motor is output to the propeller. A control controller controlling the prime motor, the variable capacity hydraulic pump, the variable capacity hydraulic motor, and the hydraulic pump CVT, and the like is connected thereto. The control controller controls the power of the variable capacity hydraulic motor using the planetary reducer and the hydraulic pump CVT so as to actuate the prime motor at a best fuel consumption amount point. The control controller is operated to be able to regenerate the control depending on an environment. |
