The invention discloses a dynamic control method and system for rail vehicles under braking release failures. On the basis of using a brake state signal fed back by a train line to judge the braking release failures, a brake cylinder pressure signal is added, and the braking release failures are judged by the combination of the brake state signal and the brake cylinder pressure signal, when the brake state signal indicates a failure state and the brake cylinder pressure signal indicates a normal state, it is judged as a minor failure, and the vehicles are not towed and blocked according to braking un-release serious failures, and the operating efficiency is effectively improved; and when it is judged as a braking un-release serious failure, the allowable maximum operating speed is obtainedaccording to a relationship curve, and the operating speed of the vehicles are automatically controlled at the maximum operating speed, manual intervention is reduced, safety accidents are avoided, and the operating efficien
