Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile air conditioning control, and particularly relates to an open-loop automatic air conditioning control calibration method and system. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] With the rapid development of the automobile industry and the increasing demand of consumers for driving comfort, the automobile air conditioning system has developed from a simple temperature regulating device to a complex system integrating intelligent control, energy saving and environmental protection. In the prior art, the automatic air conditioning system mainly adopts a closed-loop control method to achieve precise temperature regulation.

[0004] Traditional closed-loop automatic air conditioning control systems usually need to arrange multiple temperature sensors in the HVAC assembly or air duct, including face blowing outlet temperature sensors and foot blowing outlet temperature sensors. These sensors monitor the outlet temperature in real time and feed back the data to the air conditioning control unit, which adjusts the compressor speed, heater power, and mixed air door position through the PID algorithm to achieve precise control of the outlet temperature. Although this control method can provide good temperature regulation effect, it has many problems in actual application: During the facelift process of a vehicle model, the arrangement position of the sensors often needs to be redesigned due to the adjustment of the instrument panel interior structure. This not only increases the development cost, but also prolongs the development cycle. Especially under the background of the gradual popularization of electric air outlets, the arrangement space of traditional sensors is severely limited, and even cannot be realized on some vehicle models.

[0005] Secondly, the sensors in the prior art are usually arranged near the outlet of the HVAC assembly, not at the terminal position of the actual outlet. Due to the heat radiation and heat conduction effect of the air duct, there is a significant difference between the sensor measurement value and the actual outlet temperature reaching the passenger area, resulting in a decrease in temperature control accuracy and a serious impact on comfort experience. SUMMARY
