<p>Until an internal combustion engine (10) reaches a normal rotational speed (Nes) or above after the start of a vehicle, a second drive line is used for power transmission using "first speed" or "second speed". When upshifting while the second drive line is being used, regeneration control is implemented to have an engine rotational speed (Ne) changed to a rotational speed (Nen) for the next gear stage by an electric generator (11). When the internal combustion engine (10) has the normal rotational speed (Nes) or above, the drive line is switched to a first drive line in accordance with a demanded torque. When the internal combustion engine (10) decelerates from a state of the normal rotational speed (Nes) or above, the first drive line is selected at all times, and engine brake torque and regeneration torque of the electric generator (11) are used for deceleration. Thus, a hybrid vehicle and a method of controlling the same are provided whereby a hybrid system mounted on the hybrid vehicle can be optimally controlled to improve fuel economy without sacrificing drivability (ride).</p> |
