The Research And Design Of The Expressway Automobile Rear Collision Avoidance System And Its Main Control

In this paper, the current situation and the features of the expressway accidents in our country are analized on the base of some investigation data. The xpressway automobile rear collision avoidance system s designed. Firstly, the subsection of the system and its function diagram was described. On the base of the automobile brake process analysis, the expressway automobile safety distance calculation model is set up. According to the contrast and analysis of different distance measure methods, the research of the distance measure method is made and the system distance measure method is decided. On the base of the above, the parameters of the sensors used in the system is designed. By using MCS-5 1 language, the system main control program is designed. Finally, the test result of the system and some pieces of re-investigate advice are given.
