The invention provides a drive control mechanism of an extended-range electric vehicle. According to structure characteristics of the novel structure extended-range electric vehicle, in order to meet different driving requirements, the novel structure extended-range electric vehicle is provided with three driving gears including a conventional gear, a power gear and an economical gear, and the three gears can be manually selected by a driver. In the conventional driving mode, dynamic performance and economical efficiency of the whole vehicle are both taken into consideration. Linear pedal control is adopted, and the torque load coefficient and an acceleration pedal are in a linear function relation. In the electricity consumption stage, the whole vehicle runs in a pure electric mode. In the electricity maintaining stage, a work point of an engine is determined according to the running state of the whole vehicle and efficient running of the engine. In the power driving mode, the dynamic performance of the whole vehicle is mainly emphasized, the load coefficient and the acceleration pedal are in a convex function relation, the vehicle can quickly respond to pedal operation of the driver, and when the vehicle sharply accelerates or climbs a long slope, the engine and a drive motor together drive the vehicle to run, so that the dynamic performance of the whole vehicle is improved.
