The Obstacle Avoidance System Of Emergency Lane Change Model Based On SOPC

Thirty years of reform and opening up, especially since entering the21st century, withthe rapid development of Chinese economy, the basic design of the building tend to improvepeople ’s living standards have been greatly improved. More and more people in the choice oftransportation between cities by car highway travel. Accordingly, the total number of highwayaccidents occurred also record high, how better to reduce traffic accidents and reduce the lossof lives and property of the people, has become the focus of attention of all countries. To findan effective and simple way to solve the problem of road traffic accidents, ongoing researchinto hot pot.The type of highway traffic accidents are also rear-end collisions and mutual rub-based,like the relative driving collision, side lateral collisions, collisions and other vehicles andpedestrians on the highway plan does not exist. On the other hand, due to the fast speed ofvehicles traveling on the highway, the road is good, the driver’s reaction does not often occurin a timely manner, or mental lax slow response time and so on. And high-speed road surfacefriction coefficient, such as fog and haze reduction or under poor visibility conditions areprone to skid, drift occurs in rain, snow and other inclement weather conditions or because oflack of lateral rub and cause traffic sight rear-end collisions.Kinematic model of the vehicle transformation by establishing roads, research highwayroad vehicle conversion factors to determine the minimum safety distance model, thedevelopment of active car crash car safety technology to reduce driver stress and drivingreduce errors in judgment caused by poor road conditions, improve traffic safety and roadcapacity will play an important role.In this thesis, the development and current status SOPC learning, focusing on the AlteraNios II soft core formula of the type and composition, followed by a focus on learning tobuild SOPC system depends Avalon bus, and in the actual implementation of the systemmodel when changing lanes, detailed introduces the SOPC system to establish the requiredhardware and software implementation process implementation process. On the other hand,we study the mathematical model of highway safety distance, comparative analysis of the twomodels in the minimum safety distance highway actual environmental conditions, choose alane change models. After we setting up the new model, the thesis analyzes the differences ofbraking action and changing lane action. Finally, used SOPC to implement the model.
