PROBLEM TO BE SOLVED: To provide a hybrid system that performs cranking of an engine by a motor generator through a continuously variable transmission mechanism, and a control method thereof.SOLUTION: In a hybrid system 1 having an engine 10 and a motor generator 21, a crank shaft 15 of an engine body 11 and the motor generator 21 are connected through a CVT 16. When there occurs a request for starting the engine 10, the motor generator 21 is rotationally driven, and after the diameter of a first pulley 16a of the CVT 16 is maximized and the diameter of a second pulley 16b is minimized, the motor generator 21 is rotationally driven, and cranking of the engine body 11 is performed. |
