Design of Automobile Airbag Multi-Point Ignition System Based on Piezoelectric Converter

Abstract:

Automotive industry is being one of the major supporting forces for the economy of many countries. The requirement of higher standard on safety figure for cars has demanded engineers to design automobile airbag systems with high performance. Since the ignition system is one of the major units in an airbag system, a design of a high-voltage piezoelectric converter which can be implemented in airbag ignition systems is studied in this paper. The selection of the piezoelectric transformer can improve the reliability by increasing the ignition energy. Using the multi-point ignition scheme to measure the orientation of the airbag detonation, the accuracy of the airbag ignition can be improved and the accidental injury caused by collisions can be further reduced. Besides, a good solution to synchronization problems is provided by using multi-point synchronization control and multiple air bags.
