Abstract: A drive arrangement of a working machine includes a differential gear, a first drive unit coupled to a first element of the differential gear, a working machine coupled to a second element of the differential gear, and a second drive unit coupled to a third element of the differential gear. The speed of the second drive unit can be superimposed on a speed that is dependent on the speed of the first drive unit, whereby the first or second drive unit can be driven at a variably adjustable speed. When a switching element is closed, an auxiliary gear stage is load-transmitting and speeds of the first and second drive units are coupled as a function of at least one transmission ratio of the auxiliary gear stage, and when the switching element is open, the auxiliary gear stage is load-free and speeds of the first and second drive units are decoupled.

Abstract: When an electrical continuously variable transmission malfunctions and the operation of an engine is stopped, an automatic transmission is caused to upshift. Therefore, when the rotation of the engine is stopped as a result of a stop of the operation, an AT input rotation speed is decreased as compared to that before it is determined that there is a malfunction in the electrical continuously variable transmission. Thus, an MG1 rotation speed is decreased in absolute value as compared to when the automatic transmission is not caused to upshift, so an overspeed of a first electric motor is prevented.

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.
