Dual-motor multi-mode driving system of electric tractor and control method thereof

The invention relates to a dual-motor multi-mode driving system of an electric tractor and a control method thereof; the dual-motor multi-mode driving system comprises an electromagnetic clutch, an A motor, a B motor, an A switching motor, a PTO high-low gear switching motor, a differential speed lock switching motor, I-gear and II-gear shifting motors, III-gear and IV-gear shifting motors, a B switching motor and a differential speed lock. The electric tractor is driven by the A motor and the B motor; after switching gears, the two motors are meshed and driven by a gear for respectively providing power output and driving wheel power. According to different positions of the control switch in the driving system, the driving system is under different power driving modes. According to the working unit information given by a complete controller, the power driving mode of the driving system is determined. The system and the method can fully display the performance of the tractor power driving system based on the d
