Research On Reverse Collision Avoidance System By Ultrasonic Orientation

The car as an important means of transport, plays a more and more importantroles in people’s life, but because of the driver itself’s unskilled, or is the impact ofroad and parking conditions, traffic accidents occur frequently.The birth of reverseanti-collisionsystem, help people solve some problems of automobile driving from acertain extent. With the continuous development of automobile technology, people arepaying more for reverse anti-collision system of the higher requirements, in order tosatisfy people’s needs, reverse anti-collisionsystem to complete the rapid developmentduring the short several years, and also has the very big development space.The main research contents in this paper is based on the ultrasonic ranging basedon fuzzy logical relationship of automobile positioning, and then use the fuzzy controlof automobile steering analysis, provides the operating instructions for the driver. Thispaper through the module to realize, presents acollision avoidance system based onultrasonic positioning. Distance measuring part of this system adopts a plurality ofultrasonic distance measurement device, is a set of location, data display, commanddisplay, voicealarm in one, can provide the driver with a help system.Based on the principle of ultrasonic distance measurement and fuzzy controltheory study, completed the hardware design of ultrasonic ranging device in thepaper, and the design of fuzzy controller. In the last part, on the ultrasonic ranging isverified by the experiment, the experimental errors are analyzed, themethod to reducethe error, verify the accuracy of the system meet the designrequirements; at the sametime, the fuzzy control simulation, verified thecollision avoidance system is reliable.
