Abstract
A hybrid transmission includes a first planetary gear set and a second planetary gear set. The first planetary gear set is constituted of a complex planetary gear train connected to an input element, a motor/generator, and a first clutch, and has four or more rotation elements. The first rotation element of the first planetary gear set is selectively connected to the input element and the first clutch is installed to selectively stop rotation of a third rotation element of the first planetary gear set. The fourth rotation element of the first planetary set is selectively connected to the motor/generator. The second planetary gear set is connected to an output element, and has four or more rotation elements.

A hybrid transmission, comprising:
- a first planetary gear set (PGS1) constituted of a complex planetary gear train connected to an input element (INPUT), a motor/generator (MG), and a first clutch (CL1), and having four or more rotation elements;
- and
- a second planetary gear set (PGS2) connected to an output element (OUTPUT) and having four or more rotation elements,
- wherein a first rotation element of the first planetary gear set (PGS1) is connected to the input element (INPUT),
- the first clutch (CL1) is installed to selectively stop rotation of a third rotation element of the first planetary gear set (PGS1), and
- a fourth rotation element of the first planetary gear set (PGS1) is connected to the motor/generator (MG),
- wherein the third rotation element and the fourth rotation element are different rotation elements.
