Abstract

An airbag system has been a standard safety system for saving a driver's and passengers' life after a crash is occurred. But it has several problems that airbags are not deployed though they must be deployed or deployed though they must not be deployed. It can make unpredicted injuries of a driver or passengers. Therefore the role of the crash algorithm to deploy airbags is very important. In this paper, a robust crash algorithm is developed to deploy airbags in a proper time when a crash is occurred. The algorithm discriminates crash types using FIS(Front Impact Sensors) first and revises it using ACU-Y sensor(acceleration sensor of Y-direction in Airbag Control Unit). After then, airbags are deployed along the discriminated crash type. In this algorithm, using the combination of both sensors, the reliability of discriminated crash type information becomes higher than when each sensor is used separately.
