对乘员约束系统进行碰撞工况识别的控制策略研究.根据汽车正面碰撞和路面干扰的模型,以及对安全气囊上常用的碰撞点火算法的分析,提出了适合该控制系统的基于改进移动窗算法的控制策略.对比的结果表明,改进后的算法不仅保留了原来移动窗算法在汽车识别正面碰撞方面具有良好的可靠性与灵敏度,还具有很好的抗路面干扰性能.%A study on the control strategy for vehicle impact identification of occupant restraint system is conducted. A control strategy based on improved moving window algorithm suitable for the control system is proposed according to the models for vehicle frontal crash and road surface interference and the analysis on common impact ignition algorithm of airbag. The results of comparison show that the improved algorithm not only retains the good reliability and high sensibility of original moving window algorithm, but also has a much better road interference resistance performance.
