The present invention relates to a dual-speed final drive control method and terminal device, and a storage medium. The method includes: S1: acquiring, according to electronic horizon data ahead, a gradient value of a road ahead, and when an absolute value of the gradient value is greater than a gradient threshold, proceeding to S2; and S2: determining, according to the gradient value, whether the road ahead is an uphill section or a downhill section, and if the road ahead is the uphill section, controlling all gears of a transmission to correspond to a higher final drive ratio in the dual-speed final drive when a vehicle travels into the uphill section; and if the road ahead is the downhill section, controlling all the gears of the transmission to correspond to a lower final drive ratio in the dual-speed final drive when the vehicle travels into the uphill section. According to the present invention, information of a road gradient predicted by electronic horizon is used in control of dynamic matching between a speed ratio of the dual-speed final drive and a speed ratio of the transmission, thereby making use of the dual-speed-ratio final drive to the greatest extent according to the terrain to improve the economy in energy consumption of the entire vehicle.
