The invention discloses an extended-range electric tractor control method and system. The extended-range electric tractor control method comprises the steps of a control time threshold value judgmentprocess, a control electric quantity threshold value judgment process and the like. A power battery pack is fully utilized, and when the operation is finished, the SOC of batteries is 25%, so that over-discharge is avoided. Therefore, the effects of energy conservation and emission reduction are achieved, the power battery pack is protected, and the service life is prolonged. And by starting a range extender, the driving range of the vehicle is increased, and normal operation of the vehicle is guaranteed. The characteristics of high energy utilization rate, flexible control and the like of themotor are exerted, the electric energy requirements under different driving working conditions are met, and the effects of energy conservation and emission reduction are highlighted; and double motors are adopted to drive the tractor, so that the performance of the whole driving system of the electric tractor can be effectively improved.
