A hybrid transmission for a hybrid vehicle is comprised of a two-degree-of-freedom differential mechanism and a brake. The differential mechanism includes at least five rotating members wherein four of the rotating members are connected to an input from a main power source, an output to a driveline, first and second mover/generators, respectively. The brake is connected to one of the rotating members and is capable of being put in an engaged state to brake the one of the rotating members. The hybrid transmission is set so that 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.
