An intelligent control system and method for a vehicle air conditioner based on fuzzy control

Abstract

The invention provides a system and method for intelligent control over an automobile air conditioner according to fuzzy control and relates to the field of control over automobile air conditioners. The system for intelligent control over the automobile air conditioner according to fuzzy control comprises a temperature detecting device used for detecting the temperature in an automobile passenger cabin, a data processing unit used for obtaining the temperature difference in the passenger cabin and the change rate of the temperature difference in the passenger cabin according to the temperature, a fuzzy controller which is used for conducting fuzzification on the temperature difference and the change rate, conducting fuzzy inference according to a control rule list to obtain a fuzzy controlling quantity, obtaining an accurate control quantity after making the fuzzy control quantity clear, and outputting an accurate control quantity signal according to the accurate control quantity and the automobile air conditioner used for changing the temperature of the passenger cabin according to the accurate control quantity signal. By the adoption of the system and method for intelligent control over the automobile air conditioner according to fuzzy control, the temperature of the passenger cabin can be rapidly changed, the temperature of the passenger cabin is kept in the degree that a driver and passengers feel comfortable, the oxygen content and the ventilation condition in the passenger cabin are also considered, the comfortable sensation of the driver and the passengers is improved, and the risk of carbon monoxide poisoning is reduced.

Description

technical field [0001] The invention relates to the field of vehicle air conditioner control, in particular to an intelligent control system and method for a vehicle air conditioner based on fuzzy control. Background technique [0002] With the rapid improvement of people's living standards, car air conditioners have become an essential device in automotive products. The manual air conditioning system cannot adjust the air in the passenger compartment in a timely manner according to the changes in the air temperature inside and outside the passenger compartment, the intensity of solar radiation, the vehicle speed, the heat load of the engine, and the heat dissipation of the driver and passengers, and the control effect is not ideal. The manual operation of the driver is required, which increases the workload of the driver. [0003] In addition, it is difficult for the driver to adjust the air conditioner according to the specific conditions of the passenger cabin temperatur...

AI Technical Summary

Problems solved by technology

The manual air conditioning system cannot adjust the air in the passenger compartment in a timely manner according to the changes in the air temperature inside and outside the passenger compartment, the intensity of solar radiation, the vehicle speed, the heat load of the engine, and the heat dissipation of the driver and passengers, and the control effect is not ideal. Manual operation by the driver is required, which increases the workload of the driver

[0003] In addition, it is difficult for the driver to adjust the air conditioner according to the specific conditions of the passenger cabin temperature. For example, when the air temperature is low, the high wind speed working mode is used, but the working mode is not adjusted in time after the temperature rises. It causes a waste of energy; another example is the long-term use of the internal circulation mode, which reduces the oxygen content of the air in the passenger compartment, reduces the comfort of the driver and passengers, and may cause carbon monoxide poisoning in some special cases.
