ARM-Based Automobile Collision Avoidance System Of Intelligent Distance

Automotive anti-collision has become the intelligent distance on international research hotspot. In practical use, the overwhelming majority of the automotive anti-collision system is based on the distance, which is simple, convenient, the advantages of low cost. This paper put forward the driveway and distance, impact-proof consisting of a kind of intelligent anticollision ranging system. In embedded ARM processor as the core, combining machine vision navigation and radar technology, try to study and establish the range of embedded system of intelligent distance bull. This is a kind of innovation.This topic design of automotive anti-collision system, intelligent distance of this situation of partial lanes, driving position relative to identify the judgment, on this basis, an intelligent distance impact-proof. This paper firstly analyzes the significance of innovation. On the analysis of the domestic and foreign research status and the research content, and introduced the embedded system processor and embedded operating system selection basis and final solution. Then on the current mainstream driveway keep algorithms in detail. In the algorithm is analyzed, and after many of this topic, and puts forward the basic characteristics and demands a set of simple and effective driveway keep algorithm. At the same time, the use of MATLAB software algorithm, each step of all had a lot of experiments of image processing, confirmed the feasibility of the proposed algorithm. Finally, the topic has established a kind of simple and reliable way of lane departure conditions, combining the judgment of the algorithm, image can be correct judgement of the left lane, just keep, unbiased, these three basic condition. Furthermore, this lane maintain algorithm through little modification, can be applied to various ways of cable to environmental tracking. On this basis, this project also established a valid the automotive anti-collision model. This model including velocity information, lanes and keep information from the information collection, traffic condition, the level of state information, and finally the effective control level alarm. Acousto-optic alarm ways for comprehensive alarm, on this basis, improve the expressway traffic safety.This car intelligent distance impact-proof system design, can meet the basic requirements of automotive anti-collision expressway. The expressway traffic safety of China's transportation efficiency has positive significance. This system has broad prospect of application, and economic value.
