Abstract
A gear mechanism of a power train includes first and second planetary gear mechanisms, which respectively include first to third rotating elements and fourth to sixth rotating elements which are each different to each other. The transmission section transfers the drive force of the second rotating element to the fourth rotating element. A rotating shaft fixing section of a power train integrally operates the rotating shafts of the third and fifth rotating elements. A variable transmission section of a power train includes an input section where drive force is input and an output section configured to output drive force equal to or less than the input drive force. A drive force conversion control section of a controller controls the variable transmission section to enable the output of the engine to be converted to an appropriate drive force and the converted drive force to be transferred to the output shaft.
