Abstract

A method and apparatus for controlling an electric-drive vehicle in descending a long slope under a full SoC, and a medium. The method comprises the following steps: detecting a road scenario of a distributed electric-drive vehicle; detecting an electric braking torque request situation according to the road scenario; and executing a drive axle bimodal switching policy according to a drive axle electric-drive temperature and the electric braking torque request situation of the distributed electric-drive vehicle. By means of sensible electric braking force distribution to the front and rear axles, it can be ensured that during the braking process of the electric-drive vehicle when descending a slope under a full SoC, mechanical braking thermal failure does not occur, and battery pack overcharging and damage does not occur; no additional production and development costs are necessary, the safety of the vehicle as a whole and personal safety is ensured, the rate of malfunction of the electric vehicle is reduced, the applicability and suitability of the electric vehicle are improved.
