The invention discloses a vehicle collision detection method and vehicle collision detection system based on a vehicle-mounted intelligent terminal. The method comprises the following steps that the vehicle-mounted intelligent terminal collects time sequence data in real time through a sensor installed on a vehicle; a time interval is intercepted from the collected time sequence data; whether thevehicle stops in the time interval or not is judged; if yes, the parking moment in the time interval is determined; a new time interval of data comprising a first parking moment and a plurality of moments adjacent to the first parking moment before and after is re-intercepted from the time sequence data, and whether collision detection needs to be carried out in the new time interval is judged; and if detection is needed, the change condition of vehicle body parameter values in the new time interval is analyzed. According to the vehicle collision detection method and the vehicle collision detection system, by improving a collision detection algorithm, the accuracy rate of collision detection can be effectively improved, and the false alarm rate is reduced.
本发明公开了一种基于车载智能终端的车辆碰撞检测方法及系统;包括如下步骤:车载智能终端通过车辆上安装的传感器实时采集时序数据;从采集的时序数据中截取时间区间;判断在所述时间区间中所述车辆是否出现过停车;若出现过停车,确定所述时间区间中的停车时刻;从所述时序数据中重新截取包括第一停车时刻以及与第一停车时刻前后相邻的多个时刻的数据的新时间区间,判断是否需要在所述新时间区间中进行碰撞检测;若需要检测,则对新时间区间中的车身参数值的变化情况进行分析。本发明通过对碰撞检测算法的改进,可有效提升碰撞检测的准确率,减少误报率。
