A method of controlling a speed reduction ratio includes setting a reference engine speed in correspondence with an accelerator opening, measuring the atmospheric pressure, correcting the reference engine speed in correspondence with a change of the atmospheric pressure to compensate for a change in engine output power caused by the change of the atmospheric pressure, and controlling the speed reduction ratio so that the engine speed coincides with the corrected reference engine speed.
