The invention relates to the technical field of hybrid tractors, in particular to a distributed hybrid tractor electric AMT gear shifting system and a gear shifting control method. The gear shifting system comprises a left motor, a left transmission, a left front wheel, a right motor, a right transmission, a right front wheel, a left motor controller, a right motor controller, a power battery pack, a battery management system, a whole vehicle controller, a diesel engine, a generator, a rear transmission, a differential mechanism, a left rear wheel and a right rear wheel. According to the gear shifting system, high-speed and low-speed gear setting of the tractor is considered, a gear selecting module is omitted, two gears are controlled through a single gear shifting module, control is convenient, the cost is low, the gear shifting system is particularly suitable for common low-horsepower tractor manual gearbox structures on the market, and the electrification degree of a tractor gearbox is improved; the method can reduce the variation amplitude of traction force of the tractor in the gear shifting process, reduce pause of the tractor in the gear shifting process, improve the gear shifting success rate in tractor operation and improve the operation efficiency.

    本发明涉及混合动力拖拉机技术领域,涉及一种分布式混动拖拉机电动AMT换挡系统及换挡控制方法,该换挡系统包括:左电机、左变速器、左前轮、右电机、右变速器、右前轮、左电机控制器、右电机控制器、动力电池组、电池管理系统、整车控制器、柴油机、发电机、后变速器、差速器、左后轮和右后轮;本发明的换挡系统考虑拖拉机高低速挡位设置,取消了选挡模块,用单个换挡模块控制两个挡位,便于控制,成本较低,尤其适配于市面上常见小马力拖拉机手动变速箱结构,提升了拖拉机变速箱的电气化程度,本发明的换挡控制方法,该方法可以降低换挡过程中拖拉机牵引力变化幅度,降低换挡时拖拉机顿挫,提高拖拉机作业中换挡成功率,提升作业效率。
