Power output apparatus and motor vehicle equipped with power output apparatus
First Claim
1. A power output apparatus that outputs power to a driveshaft, said power output apparatus comprising:
- a first internal combustion engine;
a second internal combustion engine;
a first motor;
a second motor; and
a multi-axes-type power input output mechanism that has multiple axes including four axes, that is, a first axis linked to an output shaft of the first internal combustion engine, a second axis linked to an output shaft of the second internal combustion engine, a third axis linked to a rotating shaft of the first motor, and a fourth axis linked to a rotating shaft of the second motor,where one of the four axes is connected to the driveshaft, rotations of two of the four axes depend upon rotation speeds of remaining two axes of the four axes, and at least part of powers of the first internal combustion engine, the second internal combustion engine, the first motor, and the second motor are output to the driveshaft with balance of powers input to and output from the multiple axes.

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).
