Based On Monolithic Integrated Circuit SPCE061A Automobile Air Conditioning Control System

Along with the domestic automobile profession high speed development, the automobile air conditioning more and more receives the automobile manufacturer the value. Now the domestically produced automobile automobile air conditioning controller generally uses the manual machinery control mode, falls behind greatly the international standard, has limited the automobile industry development. This article has conducted a series of research in view of the realization automobile air conditioning automatic control question. Uses the fuzzy control theory to carry on the intelligent control to the automobile air indoor temperature governing system. The fuzzy control method has the strong robustness, can precisely control in the vehicle the temperature, satisfies the human body comfortable request. This article through to automobile air conditioning indoor temperature adjustment process analysis, according to the fuzzy control rule storehouse decomposition principle, divides into the entire controller more than six inputs lists output the fuzzy controller. (Hypothesis temperature and vehicle room temperature) carries on fuzzy processing to the input signal, established mixed the air throttle, the air blower rotational speed, the compressor and the hot water valve, the wind direction air throttle and inside and outside cyclic control fuzzy control rule. According to input, the output request has carried on the design to the control system hardware, including data acquisition, man-machine channel design. According to the fuzzy control rule and the input, the output connection request carries on the design to the software.
