Abstract: A vehicle (10) has mounted therein an engine (2), a first rotating electric machine (3), and a second rotating electric machine (4). The power of the engine (2) and the power of the first rotating electric machine (3) are separately transmitted from different power transmission paths (41, 42) to drive wheels (5). The power of the engine (2) is also transmitted to the second rotating electric machine (4) and utilized to generate electrical power. The vehicle (10) is provided with a connecting/disconnecting mechanism (8) on the power transmission path (42) that transmits the power of the first rotating electric machine (3) to the drive wheels (5).

Abstract: A transmission for hybrid vehicle includes a change-speed gear assembly, an engine-side connector, and a motor-side connector. The change-speed gear assembly includes drive gears and driven gears making change-speed stages. A specific drive gear of the drive gears, and a specific driven gear of the driven gears, making a specific change-speed stage (e.g., the fifth-speed change-speed stage) of the change-speed stages, are made switchable between the idling state and the rotary connection state. The engine-side connector switches the other drive gears and driven gears, making the other change-speed stages, between the idling state and the rotary connection state, respectively. The motor-side connector includes a motor-side drive gear meshing with a motor-side driven gear doubled as the specific drive gear. The motor-side connector switches the specific drive gear, and the specific driven gear between the idling state and the rotary connection state, respectively.
