The invention provides a hybrid power tractor driving system and a control method thereof. The hybrid power tractor driving system is characterized by comprising a power system (1), a power generation system (2), a control system (3) and an energy storage system (4), the power generation system (2) and the energy storage system (4) are respectively connected with the power system (1) through the control system (3) and carry out power output; through power coupling and power decoupling of the double motors, the efficiency interval of the driving motors can be widened, the system operation efficiency can be improved, the power requirements of the tractor under various complex operation working conditions can be met, and meanwhile the weight of the driving system is reduced; and multiple driving modes can be provided through the dual-motor power confluence driving system, and the motors are kept to work in a high-efficiency area under a large load, so that the working efficiency of the motors is improved, and better economical efficiency is obtained.

    本发明提供一种混合动力拖拉机驱动系统及其控制方法,其特征在于:包括动力系统(1)、发电系统(2)、控制系统(3)及储能系统(4);所述发电系统(2)和储能系统(4)分别通过控制系统(3)连接动力系统(1)并进行动力输出;通过双电机的动力耦合和动力解耦,能够拓宽驱动电机的效率区间,提高系统运行效率,可以满足拖拉机在各种复杂运行工况下的动力需求,同时降低驱动系统的重量;且通过双电机动力汇流驱动系统可以提供多种驱动模式,并在大负载下保持电机在高效率区域工作,从而提高了电机的工作效率,获得更好的经济性。
