The embodiment of the invention provides a train braking method, device and equipment and a storage medium. The method comprises the following steps: determining a first actual slip rate and an adhesion coefficient of each wheel set in a current control period; determining a first optimization parameter value of each wheel set in the current control period according to each first actual slip rateand the corresponding adhesion coefficient; obtaining a second optimization parameter value and a second actual slip rate of each wheel set in the previous preset number of control periods; determining a braking strategy of each wheel set according to the first optimization parameter value, the second optimization parameter value, the first actual slip rate and the second actual slip rate of eachwheel set; and controlling the corresponding wheel set to brake according to the braking strategy of each wheel set. After influence of the slip rate on the train operation safety is considered, adhesion between wheel rails can be fully utilized to obtain a short braking distance, and train braking can be accurately regulated and controlled when the slip rate is too high, so that the train operation safety is ensured.

    本发明实施例提供一种列车制动方法、装置、设备及存储介质,该方法包括:确定当前控制周期各轮对的第一实际滑移率和黏着系数;根据各第一实际滑移率和对应的黏着系数确定当前控制周期各轮对的第一寻优参数值;获取前预设个数控制周期各轮对的第二寻优参数值和第二实际滑移率;根据各轮对的第一寻优参数值,第二寻优参数值,第一实际滑移率及第二实际滑移率确定各轮对的制动策略;根据各轮对的制动策略控制对应的轮对进行制动。可在考虑滑移率本身对列车运行安全的影响后,不仅能够充分利用轮轨间的黏着来得到较短的制动距离,还能够在滑移率过大时,对列车制动进行精准调控,以保证列车运行安全。
