The invention relates to a double-speed main speed reducer control method, terminal equipment and a storage medium, and the method comprises the steps: S1, obtaining a slope value of a front road according to front electronic horizon line data, and entering S2 when the absolute value of the slope value is greater than a slope threshold value; and S2, judging whether the road ahead is an uphill road section or a downhill road section according to the gradient value, and when the road ahead is the uphill road section, controlling a vehicle to drive into the uphill road section, and enabling all gears of a transmission to correspond to a larger main reduction ratio in a double-speed main speed reducer; and when the vehicle is in the downhill road section, controlling all gears of the transmission to correspond to a smaller main reduction ratio in the double-speed main speed reducer when the vehicle is driven into the downhill road section. The prediction information of the road gradient by the electronic horizon is used for the dynamic matching control of the speed ratio of the double-speed main speed reducer and the speed ratio of the transmission, and the effect of the double-speed-ratio main speed reducer on the improvement of the energy consumption economy of the whole vehicle is exerted to the maximum extent according to the topographic condition.

    本发明涉及一种双速主减速器控制方法、终端设备及存储介质,该方法中包括:S1:根据前方电子地平线数据获取前方道路的坡度值,当坡度值的绝对值大于坡度阈值时,进入S2;S2:根据坡度值判断前方道路为上坡路段还是下坡路段,当为上坡路段时,控制车辆在驶入该上坡路段时,将变速器的所有档位对应于双速主减速器中较大的主减速比;当为下坡路段时,控制车辆在驶入该下坡路段时,将变速器的所有档位对应于双速主减速器中较小的主减速比。本发明将电子地平线对道路坡度的预测信息用于双速主减速器速比与变速器速比的动态匹配控制,根据地形情况,最大程度上发挥双速比主减速器对整车能耗经济性提升的作用。
