Development of Vehicle Airbag Ignition Algorithm Based on Power-Rate Method

Abstract

In order to solve the high false triggering rate problem of vehicle airbag, a new airbag ignition algorithm based on power rate method was developed. In this paper, vehicle crash test data at different speeds was used and three parameters of acceleration Jerk and velocity were selected to determine the crash density. Finally, low-speed impact test, high-speed impact test and 40% offset impact test was conducted to validate the algorithm. The results demonstrated that the algorithm was of better sensibility and robustness.
