Patent ID: 6887175

Claim:
A hybrid transmission for a hybrid vehicle, comprising: a differential mechanism including at least five rotating members, the rotating members being interlinked so that rotating conditions of all of the rotating members are determined when rotating conditions of two of the rotating members are determined, five of the rotating members being connected to an input from a main power source, an output to a driveline, first and second mover/generators and a brake, respectively; wherein the fastest rotating member and the slowest rotating members is connected to the first and second motor/generators, respectively, when the rotating members are revolving with a revolution speed difference, wherein the revolution speeds of the rotating members connected to the brake, the input and the output are between the revolution speeds of the rotating members connected repectively to the first and second motor/generators, the brake is capable of being put in an engaged state to brake the rotating members, and wherein an absolute value of a revolution speed of the rotating member connected to the output is greater than an absolute value of a revolution speed of the rotating member connected to the input when the brake is put in the engaged state.
