ABSTRACT:
A motor (MG1) is connected to a sun gear (31) of a first planetary gear (P1) of a power distribution/unification mechanism (30), an engine (EG1) is connected to a carrier (34) of the first planetary gear (P1) and a ring gear (37) of a second planetary gear (P2), an engine (EG2) is connected to a ring gear (32) of the first planetary gear (P1) and a carrier (39) of the second planetary gear (P2), and a motor (MG2) and a drive shaft (65) are connected to a sun gear (36) of the second planetary gear (P2). Drive control is made by selecting an operation pattern from the following operation patterns, the operation pattern to be selected is the pattern enabling efficient operation according to a demand by an operator: a first operation pattern where power is outputted from the engine (EG2) to the drive shaft (65), a second operation pattern where power is outputted from the engine (EG1) to the drive shaft (65), a third operation pattern where power is outputted from both engines (EG1, EG2) to the drive shaft (65), and a motor operation mode where the engines (EG1, EG2) are stopped and power is outputted from the motor (MG2) to the drive shaft (65).
