Automobile air-conditioning control method and device based on online correction

Abstract

The invention relates to the field of air conditioning equipment and discloses an automobile air-conditioning control method based on online correction. The method comprises the following steps: according to the longitude and latitude of a vehicle, a server obtains any one or several of the weather information, the current road condition information, road type information and elevation information around the vehicle; according to any one or several of the road type information, the positions and number of solar sensors, the advancing direction and the angular separation of direct solar radiation, the server determines or corrects an illumination value; according to one or several of the outside air quality, the number of the sensors, the road condition information and outside temperature, the server determines or corrects an air quality index; the server sends the obtained or processed date to an automobile air-conditioning processor, and the automobile air-conditioning processor controls an air conditioner according to the parameters. By adopting technology, the method can improve the comfort of the vehicle and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioners, in particular to a method and device for controlling vehicle air conditioners based on online correction. Background technique [0002] At present, in order to improve the comfort of the vehicle's internal environment, the vehicle air conditioner needs to obtain sufficient environmental information for analysis and calculation to control related components to adjust the working mode to improve the comfort of the vehicle's internal environment. The current mainstream method of obtaining environmental information is to use the installation Various sensors on the vehicle collect corresponding data, and then transmit the data to the vehicle air conditioner through the bus or radio frequency for conversion and processing to obtain this information. [0003] The mainstream sensors for obtaining environmental information include: temperature sensor, humidity sensor, sunlight sensor, air...

AI Technical Summary

Problems solved by technology

[0005] (1) The sensor cannot obtain real-time road conditions, altitude, road type and other information that affects the comfort of the car environment;

[0006] (2) Installing too many sensors will directly lead to an increase in cost; and the more sensors there are, the more data needs to be processed, which will lead to: more complex programming logic, making software development more difficult; more demanding requirements for vehicle air conditioners High, making the cost increase;

[0007] (3) Only using the sensors on the vehicle is not enough to ensure the accuracy of the acquired environmental information. For example, the sunlight sensor is usually installed in front of the center console in the car. Change, but at this time the light intensity data detected by the sunlight sensor will be quite different from the real situation, which will directly lead to an error in the judgment of the processor; if the data measured by some sensors in a low temperature environment exceeds the error range, this will also lead to The processor makes wrong judgments and affects the comfort of the car environment
