This graduation project's primary mission is the automotive air conditioning control system's design, this system unifies the ATmega16L monolithic integrated circuit and some peripheral device component (for example ULN2003, SC16312, L9997ND) the application, the recombination control plan's software routine realizes. The treating plant mainly has the following input signal in this set of control system: Che Neinei was mad that outside the temperature signal, the vehicle the external Qi temperature signal, the water temperature temperature signal, the air blower feedback signal, the mix air throttle feedback signal, the back light lamp signal and so on, the output device is the VFD fluorescence vacuum display monitor, the control device is mainly on control panel's pressed key, realizes the plan acts according to the vehicle speed, Each temperature value's situation comes the intelligent control air-conditioning system various air throttles electrical machinery and compressor's work, causes in compartment's temperature basis hypothesis temperature in the physical sensation comfortable scope, simultaneously controls the blowing through the air throttle electrical machinery's movement the direction, the cold hot blast proportion, the automatic control, forces to defrost, the inside and outside circulates the wind transformation and the breakdown situation demonstration is the concrete function which this set of control system can realize. This article introduced the automotive air conditioning control system's design proposal, through this plan, the detailed showing control system's structure, as well as the control system function's description, the hardware circuit realized the main chip which needed, selective analysis hardware circuit's realization, has given can realize the function specifically the actual circuit diagram. Then the basis automatic air-conditioning system's control plan, gives the software routine the main thought that unifies the monolithic integrated circuit command system to write the software flow chart.

The graduation project's main task is to control auto air-conditioning system design, the system is the combination of ATmega16L microcontroller and a number of peripheral devices (such as ULN2003, SC16312, L9997ND) applications, combined with the control scheme achieved by the software program. The control system in treatment plants mainly in the following input: the temperature inside the signal, the vehicle outside temperature signals, signals the temperature of water temperature, fan feedback signals, mixed-signal throttle feedback, backlight signal, output device for VFD Vacuum fluorescent displays, control device is mainly on the control panel button, and the programme is based on speed, the temperature of the air-conditioning systems to intelligent control of the throttle motors and compressors work, making the temperature inside the set in accordance with Temperature in the body feel comfortable within the scope of, and through the throttle to control motor movement in the direction briefing, the proportion of hot and cold wind, automatic control, mandatory defrost, air circulation inside and outside the conversion and failure are shown this control system Can be achieved by the specific function. In this paper, automotive air-conditioning control system design, through this programme, detailed description of the structure of the control system, control system and a description of the hardware required to achieve the main circuit chips, the focus of the realization of the hardware circuit, is given to To achieve the specific function of the actual circuit. Then automatic air-conditioning system under the control of the programme, the software program is the subject of ideology, system integration MCU instructions to write software flow chart.
