本文对汽车灯具的LED开发进行阐述,通过分析目前开发的线路形式、接口定义、保护方式等,同时针对开发过程中发生的常见问题及解决方案,论述了灯具用LED开发的相关要点。汽车灯具是汽车安全的的重要零部件,担负着照明和信号指示的功能。同时汽车灯具也是汽车造型的关键元素。所以越来越多的汽车厂都非常重视灯具的开发。随着技术的发展,汽车灯具的光源从传统的卤素光源逐渐向LED光源转换。而伴随着LED工艺能力及功率的提升,LED的车灯功能从单一的信号指示逐步拓展前雾灯,远近光灯。LED特有的造型便利性,让灯具的造型更加多变,更加富有魅力,使车灯LED成为一种趋势。 相似文献

A high-functionality tail lamp system aimed at reducing the risk of rear-end collision was developed and installed on the ASV-2, prototype vehicle produced in the second phase of the Advanced Safety Vehicle program promoted by the Ministry of Land, Infrastructure and Transport of Japan. This paper presents experimental findings concerning basic driver cognition and response behavior in connection with stop lamp illumination and approach to a preceding vehicle. It also describes the main functions of the system comprising an emergency braking advanced advisory and large high-mounted stop lamps. 相似文献

The paper presents a survey on parameter identification techniques for complex vehicle models. In order to cope with the complexity of the model, the information on the system available from the equations of motion has to be included in the identification process. Basic methods for the solution of this problem are shown. The application of the approach is demonstrated by identification of the vertical automobile dynamics. It is concluded that the presented techniques will become more important with increasing applications of theoretical modeling in vehicle system dynamics. 相似文献

This paper pursues two objectives: Firstly, to review the state-of-the-art of general purpose vehicle system dynamics software and secondly, to describe two representatives, the program MEDYNA and the program NEWEUL. The general modeling requirements for vehicle dynamics software, the multibody system approach and a comparative discussion of multibody software are given. The two programs NEWEUL and MEDYNA are described with respect to modeling options, computational methods, software engineering as well as their interfaces to other software. The applicability of these programs is demonstrated on two selected examples, one from road vehicle problems and the other from wheel/rail dynamics. It is concluded that general purpose software based on multibody formalisms will play the same role for mechanical systems, especially vehicle systems, as finite element methods play for elastic structures. 相似文献
