Study And Exploration On The Vehicle Side Face Anti-collision Warning System

Safety is always one of the most important topics in vehicle engineering. In recent years with the rapid development of transportation, traffic accidents of highway, especially the freeway malignant traffic accident are greatly increasing. Safety problem in transportation is increasingly. In this case, the vehicle side face anti-collision warning system emerges with the tide of times. This system is a complicated system that equipped with advanced technology such as vehicle engineering, man-machine engineering, communication technology, vehicle engineering computer etc. It is on the top level in the research field of vehicle , represents the development direction of vehicle technology in the future.Beginning with the active safety of vehicle, this paper makes a deep study on the research field vehicle anti-collision warning, it can provide theory and technical support for the research on vehicle safety assistant driving in our country. This paper is base on the actuality of vehicle technology in our country, makes a theoretical study on the side face anti-collision in the course of lane Changing and vehicle overtaking.Firstly, this paper introduces the study backdrop of the task, recapitulates study actuality of anti-collision warning system in the our country and oversea;introduces mathematics model and design project. this paper discuss design ideation and the function of cell module in the mass, introduces the theory of measuring distance by ultrasonic sensor especially; Real-time, precision and reliability of system is fully considered. This paper uses a single chip Microcomputer of 8 bits P89V51 series that is the control center of the system; According to the and analyzes the work environment of system, educes conception and project of the software and hardware anti-jamming technologiesThis paper analyzes the principle and application of CAN-bus which is used widely in the modern vehicle. Vehicle side face anti-collision warning system is developed, which is based on CAN-bus technology. Referring to CAN-bus standard, it constitutes the and other control protocols among the units, and the communication between computer and the ultrasonic sensor on CAN-BUS is realized by C program.The system runes stably on the car, the ability of interference rejection is strong.
