Passenger Car Interior Microclimate Regulation And Intelligent Control

With the improvement of the economic level of our country and the development of the industrial technology of the automobile, the demands on the air conditions in the car are higher and higher, including not only the control on hot environmental parameters but also the regulation and control of the air composition in the car in order to improve the demands of comfortableness and security. The air conditioning now used in the car, which can only control the hot environmental parameters in some degree, can't satisfy such demands. Beginning with the existing problems of air conditioners, this master thesis covers the principles to regulate and intelligently control the air conditions in the care and the ABC involved in the design process. This text put great emphasis on to research and study below important problem proceed detailed:First,researched the analysised the parameters of small weather inside car, and make sure control parameters, so as to develop the controlling system. Second,apply control theories of the fuzzy to the control of the temperature and humidity inside car, design the controller by test and simulating. Third,research and analysis test of exhaust harmful air of the car and warning if it exceed the limit .How applied the speech integrated circuit comes realizing to proceeds to study.Fourth,research and discussion encouraging of driver and lowering the traffic accident , bring upped the homologous project.Fifth5,set upped the system of the regulation and intelligent control of the air conditions with MCS-51 for core parts . Passing test and simulating ,the system can completing the special function .It can expansion application in the cars .
