Kind Code:
A1
Abstract:
A method, apparatus and device for avoiding the accidental deployment of an airbag and a storage medium, the method comprising: acquiring an elastic wave signal generated by vehicle collision, and converting the elastic wave signal into a voltage signal (S101); determining, according to the voltage signal, whether a detected vehicle collision is a bottoming-out collision (S102); acquiring acceleration data in the traveling direction of a vehicle (S103); determining whether a first deployment condition is met on the basis of the acceleration data in the traveling direction of the vehicle (S104), the first deployment condition comprising the acceleration data in the traveling direction of the vehicle reaching a first deployment threshold; and when the vehicle collision is not a bottoming-out collision and the acceleration data in the traveling direction of the vehicle meets the first deployment condition, deploying an airbag (S105). The present invention helps to avoid the accidental deployment of an airbag caused by the bottoming out of a chassis, and reduces corresponding damage caused by such accidental airbag deployment.
