一种关于车辆事故紧急呼救系统触发方法的新观点

介绍车辆事故紧急呼救系统的组成和基本原理以及发展状况。通过总结和分析已有车辆事故紧急呼救系统的触发方法,发现大多数的紧急呼救系统都是以安全气囊的点火信号作为其触发信号。那么,当安全气囊在车辆正常行驶或是受到微小的碰撞的情况突然展开或是在发生严重碰撞的情况下没能及时展开的时候,就会导致车辆呼救系统的误报警现象。针对其误报警现象,提出了一种能降低误报率和改善判断事故发生准确性的新观点。

A New Standpoint about Trigger Algorithm of Vehicle Emergency Call System

The principle and researching content of vehicle emergency call system are introduced and its applying status at home and abroad is reviewed.Then by analyzing the triggering methods of the existing emergency call system,it is found that most of them use an algorithm of airbags as trigger.This can lead to false alarms of emergency calls,when airbags cannot work as expected,such as deploying under normal driving conditions or in minor collisions and not deploying in severe crashes.So a new standpoint is indic...
