基于单片机模糊控制的汽车智能雨刮器设计

ABSTRACTThe automotive industry is one of the most critical industries in ourcountry.Modern cars are developing from a single simple means of transportation tomeet people's needs,safety,energy conservation and environmental protection.Thewiper is an automobile accessory and is an important part of the car's safe driving.It isused to eliminate the rain,snow,dust and cement on the windshield,the rear windowglass and the large lamp glass,in order to ensure the transparent and clear glass.The system is composed of five parts:single chip microcomputer control circuit,rainfall collecting circuit,wiper driving circuit,LCD display circuit and communicationcircuit.First,the rainfall is collected through the rainfall collecting circuit,the data istransmitted to the single chip microcomputer,and the corresponding rainfall data isdisplayed by the LCD display circuit,and the root is then root.According to the amountof rainfall to adjust the wobble speed of the wiper,the best fuzzy control scheme issimulated by MATLAB,which is converted into the C language expression pattern,andis transplanted into the single chip microcomputer.The fuzzy controller is used to solvethe problem of the synchronous wiper.Finally,the communication circuit is mainly usedto realize the communication between MCU and PC,so that the program can bedownloaded and debugged.KEYWORDS:Singlechip;fuzzy control;Rainfall detection;MATLAB
