A Study of Algorithm of Automobile Airbag Deployment which is Based on Artificial Neural Network

对安全气囊点火时刻的准确控制是气囊系统起到保护乘员作用的关键技术。点火控制算法是实现气囊适时准确点火的手段。本文提出了一种基于人工神经网络的汽车安全气囊点火控制算法。算法构造了一个三层人工神经网络,利用碰撞发生时的减速度信号和乘员重量为输入信号,其输出信号为乘员的头部位移,作为气囊触发的一个依据。

Controlling exactly the time of airbag deployment is the key technology. Deployment algorithm is the main means to carry out airbag deployment at correct time. The article puts forward an airbag deployment algorithm which is based on Artificial Neural Net- work . The algorithm structures a three layer ANN. The input signal of the ANN is the acceleration pulse and weight of passenger or driver ; the output of it , as one of airbag deployment conditions , is displacement of the passenger~ or the driver＇s head.
