Airbag Deployment System Based On Pre- Crash Information

Abstract

An airbag is a vehicle safety device. Its purpose is to cushion occupants during a crash and provide protection to their bodies when they strike interior objects such as the steering wheel or a window. Airbags are directly linked to the life of the driver and passengers, as they are used as the last resort in a collision. Hence the proper functioning of the system is an important issue. Hence, to ensure the precision and reliability of airbag operation, it is necessary to design a robust system. Though many companies are working on the optimal deployment time for airbags, several problems still occurs. For example, when a vehicle operates off road or when the sensor inside the airbag control unit (ACU) receives a powerful shock, the vehicle’s airbags may inadvertently deploy, although no collision has occurred, because a crash like signal is delivered to the ACU. Also, when there is actual situation which requires airbag deployment, the software designed make faulty judgement and miss the time frame for airbag deployment. To resolve these problems, we are designing a system which can generate information about the crash scenarios before collision takes place. The system is designed using ARM11.
