汽车安全气囊点火系统设计与实现

Design and Realization of the Firing System of the Airbag System

随着对安全的考虑和要求越来越高,以及相关立法的实施,促进了更加复杂的汽车安全气囊系统的开发。由此,仅用于前向碰撞保护的基本安全气囊系统正逐渐被一种更加智能的高端气囊系统所取代。这种系统增加了对前后排乘客的侧面碰撞保护并追加了对头部和膝部保护的辅助系统。与此同时,气囊控制系统中点火回路的数量及控制复杂度也相应增加。该文对安全气囊点火系统进行了相应的研究和设计。

Since the consideration and requirement of safe draw more and more attention,and interrelated legislative＇s action,advanced the evolution of ever more sophisticated automotive airbag systems. As a resuh,basic air bag systems that serve as frontal collision protection for front seat occupants are being replaced by intelligent,high-end air bag systems that also include side protection for both the front and rear passengers and supplementary systems for addi- tional head and knee protection. At the same time,the air bag system＇s firing loop number and the complexity of system control increased. The paper introduces the design of the firing system.
