An embodiment of the invention discloses a medium-low-speed magnetically levitated train braking control method and device. The method includes: receiving a braking command including braking force intensity; judging whether current electric braking force meets the braking force intensity requirement of the braking command; on no judgment, adjusting a levitating gap in an allowable range of the levitating gap according to the braking command. Due to the fact that the size of the levitating gap affects the electric braking force intensity, the electric braking force can be adjusted effectively, mechanical braking pad friction is reduced, an updating period of the mechanical braking pad is reduced, and practicality of the medium-low-speed magnetically levitated train is improved.
