Abstract:
1. A hybrid vehicle comprising a first transmission path that transmits a traction of an engine to driving wheels and a second transmission path that transmits a traction of a motor to the driving wheels, the first transmission path comprising a main gear, an output gear, a pinion gear, and a final gear, the hybrid vehicle running by alternatively selecting either the first or second transmission path or in combination thereof, wherein a clutch switches between the first transmission path and the second transmission path, the clutch directly engaging the output shaft of the engine, and the first transmission path having a non-variable first reduction gear ratio that is fixed throughout a steady running state and is smaller than a reduction gear ratio at which a maximum vehicle speed is achieved by the traction of the engine alone, wherein the first reduction gear ratio is defined by a product of a gear ratio between the main gear and the output gear and a gear ratio between the pinion gear and the final gear.
