Abstract

According to the distributed driving electric tractor and the cooperative control method, a cooperative controller can adjust the output torque of all driving motors in real time according to the working state of the tractor and the road surface load, it is ensured that the tractor can obtain the optimal power output in different working states, the system efficiency and stability are improved, and the system reliability is improved. By coordinating power output of the left rear driving motor, the left front driving motor, the right front driving motor and the right rear driving motor, the tractor can be divided into a front motor independent driving mode, a rear motor independent driving mode and an all-wheel driving mode by the cooperative controller, and the flexible driving mode can adapt to different working conditions; the adaptability and multifunctionality of the tractor are improved; the system efficiency and stability of the distributed driving electric tractor under various working conditions can be fully improved, the agricultural production cost is further reduced, the working efficiency of the tractor can be improved to the maximum extent through accurate power adjustment and driving mode switching, and therefore the production cost is reduced.

一种分布式驱动电动拖拉机及协同控制方法，本发明中协同控制器能够根据拖拉机的工作状态和路面载荷，实时调节所有驱动电机的输出转矩，确保拖拉机在不同工作状态下都能够获得最佳的动力输出，提高系统效率和稳定性，通过协调左后驱动电机、左前驱动电机、右前驱动电机和右后驱动电机的动力输出，协同控制器可以将拖拉机分为前电机独立驱动、后电机独立驱动和全轮驱动模式，灵活的驱动模式可以适应不同的作业工况，提高拖拉机的适应性和多功能性；本发明可以充分提高各种作业工况下分布式驱动电动拖拉机的系统效率和稳定性，进而降低农业生产的成本，通过精确的动力调节和驱动模式切换，可以最大限度地提高拖拉机的工作效率，从而降低生产成本等。
