Abstract
The disclosure relates to a dual-speed final drive control method and terminal device, and a storage medium. The method includes: when an absolute value of a gradient value of a road ahead is greater than a gradient threshold, determining, according to the gradient value, whether the road ahead is an uphill section or a downhill section, thereby controlling all gears of a transmission to correspond to a higher final drive ratio or a lower final drive ratio in the dual-speed final drive. The disclosure can make use of the dual-speed-ratio final drive to the greatest extent to improve the economy in energy consumption of the entire vehicle.
Claims6
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.
