ABSTRACT:
A hybrid vehicle is provided, in which lean limit operation of an engine can be achieved while consumption of electric power of a battery is suppressed when a change of engine torque in the vicinity of a lean limit is suppressed or when an air-fuel ratio is controlled so as to come close to a lean limit during engine operation. The hybrid vehicle, in which an engine, a motor-generator, and a drive wheel are mutually connected via a differential connection unit, includes a control device which maintains an output of the engine at a constant level by increasing/decreasing an engine rotational speed and decreasing/increasing a rotational speed of the motor-generator in accordance with a decrease/increase of the engine torque in the vicinity of the lean limit.
