The invention discloses a multi-train cooperative cruise control method and system considering a communication distance, and the method comprises the steps: obtaining the operation information of each train in a communication range in real time, calculating the distance and speed difference between each train and a train adjacent to the train in communication, and obtaining the maximum communication distance of the trains; obtaining a distance control variable of each train by utilizing the negative gradient of the potential function of the train and the adjacent communication train; wherein the potential function is a segmented potential function for introducing the maximum communication distance and/or a communication coefficient which is introduced into a distance control variable and represents the communication quality between the trains, and the communication coefficient is a segmented coefficient for introducing the maximum communication distance; and acting the distance control variable on a traction braking system of the train to generate traction force or braking force. According to the technical scheme, the influence of the communication distance is fully considered, and the train tracking interval is optimized according to the actual train speed on the premise that safe operation of the train is guaranteed through the brand new technical scheme, so that the overall operation efficiency of the railway is improved.

    本发明公开了考虑通信距离的多列车协同巡航控制方法及系统,该方法包括:实时获取处于通信范围内的每列列车的运行信息,计算每列列车自身与其通信相邻列车之间的距离和速度差,并获取列车的最大通信距离;利用列车与通信相邻列车的势函数的负梯度得到每列列车的距离控制变量;其中,势函数为引入最大通信距离的分段势函数和/或距离控制变量中引入表示列车之间通讯质量的通信系数,通信系数为引入最大通信距离的分段式系数;将距离控制变量作用于列车的牵引制动系统产生牵引力或制动力。本发明技术方案充分考虑通讯距离的影响,以一种全新的技术方案在保证列车安全运行的前提下,跟随列车实际速度优化列车追踪间隔,以提升铁路的整体运营效率。
