Research of Vehicle Airbag Non-deployment Cases

Abstract

In this paper, the conditions, criteria and the algorithms controlling the deployment of vehicle airbags are analysed. The sequence of the algorithm and specific thresholds used in airbags control are analysed as well. The means are provided for airbags testing to ensure their reliability and proper functioning. The types of road accidents including specific cases are described in terms of possible airbag non-deployment. The computer simulations of critical impact scenarios with a finite element model of light vehicle are done in LS DYNA software. The analysis of achieved impact force results show that even relatively small speed (30 and 50 km/h) causes different conditions for airbag deployment.
