本发明是关于一种列车紧急制动控制方法及安装在列车上的电子设备,涉及城市轨道交通技术领域,本发明包括:在检测到列车前方障碍物后,确定列车安全位置到列车前方障碍物之间的距离;确定列车需要进行紧急制动过程中每个制动阶段的当前紧急制动加速预测数据,以及确定列车的紧急制动加速预测数据、预测面积和紧急制动触发速度之间的目标函数关系;根据目标函数关系和距离,确定列车的当前紧急制动加速预测数据对应的紧急制动触发速度;根据列车的当前紧急制动加速数据对应的紧急制动触发速度,进行紧急制动控制。由于本发明通过紧急制动加速预测数据、预测面积和紧急制动触发速度之间的函数关系,提出一种紧急制动触发速度的求取方式。

    The invention relates to a train emergency braking control method and electronic equipment installed on a train, and relates to the technical field of urban rail transit, and the method comprises the steps that after an obstacle in front of the train is detected, the distance between the safe position of the train and the obstacle in front of the train is determined; determining current emergency braking acceleration prediction data of each braking stage in the emergency braking process of the train, and determining an objective function relationship among the emergency braking acceleration prediction data, the prediction area and the emergency braking triggering speed of the train; according to the target function relation and the distance, the emergency braking triggering speed corresponding to the current emergency braking acceleration prediction data of the train is determined; and performing emergency braking control according to the emergency braking triggering speed corresponding to the current emergency braking acceleration data of the train. According to the method, a calculation mode of the emergency braking triggering speed is provided through the function relation among the emergency braking acceleration prediction data, the prediction area and the emergency braking triggering speed.
