1. A series hybrid vehicle control method comprising:
charging a battery with electric power generated by an electric power generation motor that is driven by motive power from an internal combustion engine, and driving a drive wheel with a drive motor using the electric power of the battery and the electric power regenerated by the drive motor;
starting generation of the electric power by the internal combustion engine if a vehicle requested output exceeds an electric power generation start threshold value, and stopping generation of electric power by the internal combustion engine if the vehicle requested output falls below an electric power generation stop threshold value; and
producing a deceleration rate through regeneration of the drive motor that is greater in a second advancement shift position than in a first advancement shift position,
wherein at least one of the electric power generation start threshold value and the electric power generation stop threshold value in a case where the second advancement shift position has been selected is greater than a respective one of the electric power generation start threshold value or the electric power generation stop threshold value in a case where the first advancement shift position has been selected.
