As the core of automotive passive safety airbag system

airbag system plays the most important role. In order to improve the performance of airbag system

a system of peripheral acceleration sensor is designed based on MEMS. The system detects acceleration of auto in collision

and process signal through the one-piece proprietary integrated circuit

after that

the data will be delivered to airbag control unit for logical operation. Through the actual crash test

it is proved that the designed system can enhance the recognition of collision and early the ignition timing

greatly improve the performance of the airbag system.
