The invention relates to the technical field of vehicle safety, and discloses a vehicle collision detection method and device, a vehicle-mounted system and computer equipment, and the method comprises the steps: on one hand, continuously monitoring the vehicle acceleration and vehicle speed of a vehicle according to the collected data from a vehicle-mounted acceleration sensor, and on the other hand, continuously monitoring the vehicle speed according to the collected signal from a vehicle-mounted vibration sensor; according to the method, whether a vibration condition exists or not is judged in real time, and whether a vehicle collision event needing to trigger rescue occurs or not is confirmed according to the comparison result of the real-time vehicle speed, the historical vehicle speed and the preset vehicle speed threshold value only when it is judged that the vibration condition exists, so that high-frequency sampling of acceleration data through the vehicle-mounted acceleration sensor is not needed; therefore, the product cost and the alarm false triggering probability of the detection equipment can be reduced, the accuracy of the detection result and the system performance and the service life of the detection equipment are improved, and the practical application and popularization are facilitated.
本发明涉及车辆安全技术领域,公开了一种车辆碰撞检测方法、装置、车载系统及计算机设备,其方法是一方面根据来自车载加速度传感器的采集数据,持续监测所述车辆的车辆加速度和车速,另一方面根据来自车载震动传感器的采集信号,实时判断是否存在震动状况,并仅在判定存在震动状况时,才根据实时车速及历史车速与预设车速阈值的比较结果,来确认是否发生了需要触发救援的车辆碰撞事件,由此既无需通过所述车载加速度传感器进行加速度数据的高频采样,也无需时时刻刻地进行车辆碰撞的逻辑判断,使得可降低检测设备的产品成本和报警误触发概率,并提升检测结果的准确性和检测设备的系统性能及使用寿命,便于实际应用和推广。
