The invention discloses a turning monitoring and early warning method for a railway vehicle. The turning monitoring and early warning method comprises the following steps of collecting the motion state information of the vehicle, and collecting the motion state information of external pedestrians and vehicles; acquiring monitoring data returned by an acceleration sensor carried by the vehicle, and calculating the lateral acceleration of the vehicle through a preset algorithm according to the monitoring data. According to the method, lateral acceleration of the vehicle is obtained through data monitoring and calculation, meanwhile, the lateral acceleration is judged, whether the lateral acceleration exceeds the preset threshold value or not is judged, and therefore whether the vehicle suddenly turns or not is determined, and purposes of reducing the vehicle cost and improving the vehicle safety are achieved; when the vehicle suddenly turns, the vehicle can accurately and timely judge that the vehicle suddenly turns, pedestrians and the like around the vehicle can be accurately positioned, the collision possibility can be analyzed in real time, static and moving objects around the vehicle can be effectively detected, a driver can be timely reminded, and accidents in the vehicle turning process are avoided.

    本发明公开了一种用于轨道车辆的转弯监测预警方法,包括如下步骤:采集车辆自身运动状态信息,采集外部行人、车辆运动状态信息;获取车辆搭载的加速度传感器返回的监测数据,根据监测数据通过预设算法计算获得车辆的侧向加速度。本发明通过监测数据,计算获得车辆的侧向加速度,同时对侧向加速度进行判断,判断是否超过预设阀值从而确定所述车辆是否发生急转弯,实现了对降低车辆成本,且当车辆发生急转弯时能够准确及时的判断出所述车辆已经发生急转弯可准确定位车辆周围的行人等、实时分析碰撞可能性,对车辆周围静止和移动的物体都能有效地探测,具有能及时提醒驾驶员,避免车辆转弯过程中事故发生的优点。
