Research On Intelligent Vehicle Forward Collision Warning System

In recent years, China’s economic development is very fast, the quality of life of the people has been greatly improved, accompanied by the rapid development of the car, the car in people’s lives has become the preferred means of transport. Although bring a lot to our lives convenient, but accidents always a threat to our lives and give us cause great economic losses. Therefore, there is a growing emphasis on ride safety, in this background, the development of automotive anti-collision system becomes more and more urgent, so it has promising development.Before presenting the paper method, access to a lot of information, and according to the world’s hot issues we studied, we propose a new front anti-collision warning studies, including lateral, rear-end collision avoidance, etc. In this system, Which uses a number of modules, such as distance, CPU, information collection, LCD, sound and light alarm, voice and other modules, each module development and use. The hardware part of this paper is to use the AVR family of micro controllers as the core controller, to build the hardware platform, and the entire system debugging, recording some operating results. After the completion of the hardware is to software development, in the development of theoretical models designed to better integrate emergency situations encountered in real life. Here are a few main contents of this paper are to be studied.The hardware design of the system is the use of AVR series ATMEGA128as control core, using ultrasonic and radar ranging unit, at the same time using the LED classification to realize alarm function alarm device, using the voice module that can indicate whether a collision is imminent, and has the keys to realize control device, and liquid crystal display unit to display in real time. In software development, is mainly used C language to the preparation of project, so as to realize the normal operation of the whole system, and each module as ranging, acoustics-optic alarm, voice module, key device operation, such as liquid crystal display software development and eventually nesting in the main program. System theory model is established, through the statistics and analysis of automobile accidents occurred on schedule situations in life, and is now the reference model of collision, collision model to develop a new algorithm, through the system proved that this method is very practical, to provide security in traffic.Finally, summarizes the deficiency existing in this paper, and be perfected in the future research.In short, the system has the characteristics of high reliability, strong stability, streamlined. Most of the technical requirements are satisfied the design includes. Show a good running effect in the debug results to achieve the required paper requirements.
