The invention provides a safety air bag triggering method, device and equipment and a storage medium, and relates to the technical field of vehicle safety, and the method comprises the steps: obtaining an acceleration signal of a target position point in a vehicle in real time, determining an acceleration change waveform, recognizing the change condition of the pulse width of the waveform, and when the change condition of the pulse width of the waveform meets a preset pulse width condition, triggering a safety air bag. According to the application, the pulse width identification is carried out on the acceleration change waveform of the target position point under the current working condition, whether the continuously changing pulse width meets the preset pulse width condition is judged, and whether the acceleration of the target position point has oscillation change after the collision occurs is predicted by utilizing the judgment on the pulse width; therefore, whether the current working condition is a collision working condition is judged. Compared with the prior art that the two working conditions are distinguished through the maximum amplitude of the acceleration or the acceleration integral, the method can pay more attention to the change trend of the acceleration at different moments, the distinguishing result is more accurate, and consumed time is shorter.
本申请提出一种安全气囊触发方法、装置、设备及存储介质,涉及车辆安全技术领域,该方法实时获取车辆中目标位置点的加速度信号,确定加速度变化波形,并识别该波形的脉宽的变化情况,当该波形的脉宽的变化情况满足预设脉宽条件时,立即输出点爆安全气囊的指令,本申请通过对目标位置点在当前工况下的加速度变化波形进行脉宽识别,判断不断变化的脉宽是否满足预设的脉宽条件,利用对脉宽的判断,预测出目标位置点在撞击发生后,加速度是否出现震荡变化,以此判断当前工况是否为碰撞工况。相较于目前通过加速度最大幅值或加速度积分来区分两种工况,本申请更加能关注到不同时刻加速度的变化趋势,区分结果更加准确、耗时更短。
