PROBLEM TO BE SOLVED: To increase the efficiency of energy transmission, and to efficiently drive the engine of a hybrid car, even if its running condition changes. SOLUTION: The hybrid car is composed of the engine 11, a first motor M1, a second motor M2 connected to the output shaft of the engine 11, a gear unit composed at least of a first rotation element to which each rotation of the engine 11 and the second motor M2 is inputted, a second rotation element to which rotation of the first motor M1 is inputted, and a third rotation element whose rotation is outputted to the output shaft 16 of the gear unit, and a controller which drives the engine 11 on an optimum efficiency line by controlling the first motor M1. Each rotation of the engine 11 and the second motor M2 is inputted into the first rotation element, and the rotation of the first motor M1 is inputted to the second rotation element. Rotation is outputted to the output shaft 16 of the gear unit from the third rotation element. |
