The invention discloses a power gear shifting transmission downshift control method based on gear shifting quality optimization. The actuating time sequence of the gear shifting clutch is reasonably controlled, and meanwhile, the gear shifting quality is optimized by adopting a particle swarm genetic algorithm, so that a power cycle phenomenon does not occur in the downshift process, the quality of the power gear shifting transmission can be effectively improved, the performance of the power gear shifting transmission is further improved, and the operation quality of a tractor is ensured.

    本发明公开了一种基于换挡品质优化的动力换挡变速器降挡控制方法,是通过对换挡离合器作动时序进行合理控制,同时采用粒子群遗传算法对换挡品质进行优化,从而在降挡过程中不出现功率循环现象并能有效提高动力换挡变速器品质,进而提高动力换挡变速器性能,并保证拖拉机作业质量。
