The invention discloses a vehicle falling-into-water detection method and system, electronic equipment and a storage medium. The method comprises the steps that echo detection information output by an ultrasonic sensor in a first time period is acquired; acquiring vehicle body motion detection information output by the inertial measurement unit in a second time period; judging whether abrupt change echo information exists or not according to the echo detection information, and if the abrupt change echo information exists, determining whether the vehicle is in a drowning state or not according to the vehicle body movement detection information; wherein the second time period is before the first time period in time sequence. Whether the vehicle falls into water or not is sensed through the ultrasonic sensor, then whether the posture of the vehicle body is dynamically changed or not is judged, it is confirmed that the vehicle falls into water, and compared with a traditional scheme for judging falling into water based on vision, the cost is lower, and popularization is easier; in addition, the water falling state can be judged more quickly and more accurately through ultrasonic waves.
本发明公开了车辆落水检测方法、系统、电子设备及存储介质,其方法包括:获取第一时间段内超声波传感器输出的回波检测信息;获取第二时间段内惯性测量单元输出的车身运动检测信息;根据所述回波检测信息判断是否存在突变的回波信息,若存在突变的回波信息则根据所述车身运动检测信息确认车辆是否处于落水状态;其中在时序上所述第二时间段位于所述第一时间段之前。本发明通过超声波传感器感知当前是否落水,然后判断车身姿态是否发生动态变化,确认车辆落入水中,与传统基于视觉判断落水的方案相比,本发明的成本更低,更容易普及;另外利用超声波判断落水状态更快速,准确性更高。
