1. A dual-speed final drive control method, wherein during a normal operation, a limited number gears of a transmission correspond to a higher final drive ratio and a lower final drive ratio, respectively, of a dual-speed final drive; and comprising the following steps: 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 when the road ahead is the uphill section, controlling all gears of the transmission to correspond to the higher final drive ratio in the dual-speed final drive when a vehicle travels into the uphill section; and when the road ahead is the downhill section, controlling all the gears of the transmission to correspond to the lower final drive ratio in the dual-speed final drive when the vehicle travels into the downhill section.
