Automobile automatic air conditioning control method and controller based on built-in temperature detection unit

Abstract

The present invention relates to the technical field of automobile automatic air-conditioning control, and specifically discloses an automobile automatic air-conditioning control method and a controller based on a built-in temperature detection unit, including the following steps: A. obtaining the temperature of the vehicle body; B. obtaining the temperature of the vehicle body, Calculate and output the virtual car temperature equal to the actual car air temperature; C. Control the air outlet according to the virtual car temperature. The present invention obtains the body temperature of the whole vehicle through a built-in temperature detection unit arranged on a certain part related to the air-conditioning controller, and obtains the virtual temperature inside the vehicle by using a thermodynamic model, and then completes the subsequent temperature inside the vehicle through the virtual temperature inside the vehicle The automatic control function realizes the automatic control of the temperature in the car without the need for the temperature sensor in the car, saves the cost of the temperature sensor in the car and its accompanying wiring harness, and ensures the stability and accuracy of the temperature control in the car.

Description

technical field [0001] The invention relates to the technical field of automobile automatic air-conditioning control, in particular to an automobile automatic air-conditioning control method and controller based on a built-in temperature detection unit. Background technique [0002] In the automatic air conditioning control system of modern automobiles, the central control module automatically adjusts the climate environment in the car according to the external climate conditions and the signals in the car detected by temperature and humidity sensors, so as to maintain the temperature and air volume in the car at a comfortable level. The temperature sensor in the car is an important unit in the current automatic air conditioning control system of the car. [0003] The current in-vehicle temperature sensor mainly includes two kinds of inhalation type in-vehicle temperature sensor and non-inhalation in-vehicle temperature sensor. The traditional inhalation temperature sensor ...

AI Technical Summary

Problems solved by technology

The traditional inhalation temperature sensor in the car uses the negative pressure of the air conditioning system box or the ventilation motor to inhale the air in the car, and the air flows along the pipe through the temperature sensor installed in the pipe to measure the temperature of the air in the car. The change of the air volume of the blower will lead to the change of the suction volume, and the instability of the suction volume will affect the measurement of the air temperature in the car, and the pipeline structure of the suction-type vehicle interior temperature sensor will cause the dust in the air to accumulate in the pipeline or even block it , affecting the measurement of the air temperature in the car

Although the non-suction type interior temperature sensor does not have the above-mentioned problems of the suction type interior temperature sensor, it needs to expose a sensor probe in contact with the air, which will affect the appearance of the interior of the car, and if the passenger accidentally touches the sensor The probe will affect the accuracy of the air temperature measurement in the car

[0004] Regardless of whether it is a suction type interior temperature sensor or a non-suction type interior temperature sensor, a certain production cost is required.
