The Research On Automated Guided Experiment Vehicle

Nowadays, on the other hand, with the development of urbanization and the popularization of automobiles, the environment of transportation becomes worse and worse. Traffic jams are commonly seen and accidents occur frequently. The problem of transportation has become a serious trouble concerned world-widely. On the other hand, high technology such as computer, electronics, image processing etc. develops rapidly. Based on these, a new cross-subject-IVS(Intelligent Vehicle System) thus arises. It combines various advanced technologies with automobile engineering and transportation work, aiming at reducing traffic accidents, improving efficiency of transportation and releasing the labor of the drivers. Intelligent vehicles can widely be used in not only highway transportation, but production automation, manufacturing, flexible production organization, tasks in dangerous environment and military field as well. China, with its rapidly developed power in economy, should devote itself to the study of intelligent vehicle. However, IVS is a rather complicated system that involves many high technologies in such different fields as electronics, computer, mechanism, etc. therefore, it is impossible for anybody to make an all-dimensional study on it. Besides, because of the limited conditions of economy and scientific study in our country, the study of intelligent vehicle falls greatly behind the advanced level in the world. But this does not necessarily mean that China can do nothing in this field. In accordance with our national conditions, (the economic condition, the industrial condition, and the condition of scientific study), we concentrate on one or some areas of this field, and make a thorough and careful study on them. That will provide a powerful theoretical and technological support for the study of intelligent vehicle in China as well as in the whole world, thus build a solid foundation for the development and practical utilization of intelligent vehicle. Based the above thoughts, we research the following aspects in this thesis: 1.Designed and built the experiment platform-intelligent vehicle, which be used for the theoretical and experimental study. 2.In order to navigate the vehicle quickly and reliable, it is vital to find a new method for path symbolizing which can speed up image processing. Meanwhile, the path symbolizing system is easer to be installed, changed and maintained. To achieve this goal, white stripe line is taken as the navigation lane-mark. Because only simple processing procedure is required for the lane-mark, image recognition speed can be increased remarkably. This makes it possible to realize intelligent navigation with required speed by using common CCD. 3.Carry out the analysis of the vehicle navigation and build the controller model of the vehicle steering system. Based on the model, the optimal controller and PID controller of the steering system are designed. At last, the performance of two controllers was validated by the experiment. The above researching works will provide valuable support in the theory and technology to the research of the intelligent vehicle. The researching works also will provide valuable inference to the other related projects.
