Abstract


This thesis introduces a design and implementation method of a vehicle reversingradar auxiliary driving system based on panoramic view system. The system is mainlyused in cloudy, rainy night, low visibility, the sense of distance not strong. Inconjunction with panoramic view system and radar, the running effect is best. It caneliminate the blind zone mirror and interior rear-view mirror to the driver brought aboutafter the car outside. And for the driver to provide panoramic driving state, thereby toimprove traffic safety.The system of mobile surveying system designed based on surveying system is anauxiliary function module. It is realized through computer control technology, ultrasonicranging system and organic put around reversing radar together. Ultrasonic rangingtechnology is mainly used to achieve the obstacles and vehicle distance measurement.And the measurement results are feedback to the surveying system, processed by thesurvey system, finally show the position of the obstacle information in vehicle monitor.Reversing radar is designed by top-down design method, the hardware design andthe software design of the use of theoretical analysis, circuit schematic design means ofreversing radar. Surveying system and reversing radar system integration using theWindows application in the design of MFC (Microsoft Foundation classes) programdesign method to increase a radar warning process for surveying system application.Based on the analysis of domestic and foreign reversing radar system technology,extended precision of reversing radar measurement, distance data output requirementsof each probe has the actual. Radar system based on AT89S52microcontroller as thecore, mainly by the ranging module, system control module, the distance informationoutput module, and the analysis and design of all the modules, and finally complete thedesign of hardware and software design of the whole system, and the radar test resultsof the error analysis. Looking around the system application by adding a radar warningradar, the output distance information unified processing, finally showed both a lookeffect for drivers, but also has the picture radar early warning information.Through the practical application, combined with the surveying system of radar function can be completely eliminated by visual deviation distance sense is not ng, cangreatly improve the driving safety.
