Abstract:
1. A power output apparatus for outputting a power to a drive shaft, said power output apparatus comprising: an internal combustion engine; a first motor capable of inputting and outputting a power; a second motor capable of inputting and outputting a power; a power distribution and integration mechanism including a first element connected to a rotating shaft of said first motor, a second element connected to a rotating shaft of said second motor, and a third element connected to an engine shaft of said internal combustion engine, said power distribution and integration mechanism configured such that these three elements can be differentially rotated with each other; a transmission mechanism including: a transmission differential rotation mechanism having an input element, a fixing element, and an output element that is connected to said drive shaft, and configured such that said input element and said output element can be differentially rotated with each other; and a coupling mechanism capable of selectively coupling one of or both of said first element and said second element of said power distribution and integration mechanism with said input element of said transmission differential rotation mechanism; a fixing mechanism capable of non-rotatably fixing one of a rotating shaft of said first motor and a rotating shaft of said second motor; and a control module that controls said fixing mechanism so that a rotating shaft of said first or second motor corresponding to said fixing mechanism is non-rotatably fixed when said second or first element of said power distribution and integration mechanism connected to said second or first motor that does not correspond to said fixing mechanism is coupled with said input element of said transmission differential rotation mechanism.
