Design and research on Russian ERA-GLONASS system

本文从车载紧急呼叫系统的发展历史和方向出发,介绍ERA-GLONASS系统的主要结构、工作原理及出口认证试验,研究ERA-GLONASS系统自动呼叫触发阈值与整车的匹配,确定阈值并使系统获得及时准确的有效触发;设计出一种分体式结构,并在某车型上合理布置,结构简单,通用性强;同时提出ERA-GLONASS系统研究面临的试验难度大、安装方式复杂等问题,中国自主品牌汽车走向世界还需要很多探索研究。

From the development history and direction of the vehicle emergency call system, this paper introduces the main structure, working principle and export certification test of the ERA - GLONASSsystem. Meanwhile, in this paper, the matching between the automatic call trigger threshold of ERA-GLONASS system and the vehicle is studied. A split structure is designed and reasonably placed on a car with simple structure and strong universality. At the same time, it is pointed out that the research on the ERA-GLONASS system is faced with many problems, such as the difficulty of testing and the complexity of installation methods, etc.,so it still needs a lot of exploration and research on the path of Chinese independent brand of automobile to the world.
