Problems solved by technology

[0003] However, the traditional temperature calibration method using difference compensation is highly dependent on the time axis of the air-conditioning control system. The temperature balance in the car is destroyed, which in turn affects the accuracy of the temperature sensor calibration in the car; moreover, the traditional temperature calibration method is based on the temperature set in the car, which cannot achieve accurate temperature scanning control, especially only applicable Because of single-zone temperature control, it cannot meet the requirements of precise dual-zone temperature control; in addition, the air-conditioning system of the traditional temperature calibration method is always in automatic mode, which is not suitable for manual mode, such as manual adjustment of internal and external circulation, wind speed In the case of isochronism, it cannot meet the feedback requirements of the closed-loop control of the temperature in the car
[0004] Therefore, the existing technology still needs to be improved and developed

Embodiment Construction

[0038] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0039] Since the calibration of the temperature sensor in the car air-conditioning control system is closely related to the control output of the car air-conditioning system and the environmental conditions outside the car, a BP neural network model can be established for the temperature at the sensory position of the human body in the car when calibrating the temperature sensor in the car .

[0040] Therefore, the present invention provides a dual-zone temperature calibration method under full working conditions, which is used in the automotive air-conditioning control system. When calibrating the temperature sensor in the car, a BP neural network model is establish...

Abstract

The invention discloses an all-condition double-area temperature calibration method and an automobile air conditioner control system, and a BP neural network model of the temperature at a left area and a right area where human body perception positions are can be established when a temperature sensor in a car is calibrated. The method comprises determining an input signal of a network model, collecting training data of the network model in all conditions, processing the input and the output of the network model in normalization and processing the output in reverse normalization, and initializing and training the network model using a Matlab toolset. Because the input and the output of the network model are processed in normalization and the output is processed in reverse normalization, the defect that a conventional temperature calibration method depends on a control time axis can be thoroughly overcome. On the premise that all factors influencing on a temperature sensor in a car are in consideration, the accuracy of temperature calibration and the anti-interference performance are improved, accurate feedback can be provided to an in-car temperature closed loop control system, so the stability and accuracy on temperature control can be raised by adopting the automobile air conditioner control system.
