The invention provides a deceleration closed-loop control method and device, and relates to the field of railway vehicle mechanical control. Determining the brake cylinder pressure of the locomotive vehicle brake system by using a pre-constructed friction coefficient calculation model; wherein the required deceleration is sent by an automatic driving system; the actual deceleration is obtained through actual measurement; and the brake cylinder pressure acts on the brake system to achieve deceleration closed-loop control. According to the method, the current deceleration state of the train can be obtained in real time and compared with the target deceleration, so that the brake cylinder pressure is adjusted in real time, and the deceleration efficiency is improved.
