Method and system for detecting sunlight intensity of automatic air conditioner

Abstract

The invention relates to a method and a system for detecting the sunlight intensity of an automatic air conditioner. The method comprises the following processes of acquiring the current longitude and latitude information and the real-time travelling information of an automobile by a Telematics vehicular terminal, and transmitting the current longitude and latitude information and the real-time travelling information of the automobile to an automatic air-conditioner controller; calculating the included angle gamma of the current travelling direction of the automobile and the sun by the automatic air-conditioner controller according to the current longitude and latitude information and the real-time travelling information of the automobile; judging whether the sun is within the detecting range of a sunlight sensor or not by the automatic air-conditioner controller; if so, then using a sunlight-intensity detecting value b detected by the sunlight sensor as the sunlight intensity a; otherwise, correcting the sunlight-intensity detecting value b detected by the sunlight sensor to obtain the sunlight intensity. When the sun is not within the detecting range of the sunlight sensor, the sunlight intensity a is obtained by correcting the sunlight-intensity detecting value b detected by the sunlight sensor, so that the accurate detection of the sunlight intensity a outside the automobile by the automatic air conditioner is guaranteed, and the environmental comfort level in the automobile is improved.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to a method and system for detecting sunlight intensity of an automobile automatic air conditioner. Background technique [0002] With the development of the economy, the automobile has been widely popularized as a convenient, fast and economical means of transportation. Car manual air conditioners require the driver to manually adjust the blowing mode, etc., and adjusting the car air conditioner while the car is running will distract the driver's attention and affect driving safety. [0003] In order to improve user experience and driving safety, most cars currently choose to install automatic air conditioning. To achieve automatic control of the automatic air conditioner, it is necessary to detect parameters such as the temperature outside the vehicle, the intensity of sunlight, and the temperature inside the vehicle, and automatically adjust the actuators suc...

AI Technical Summary

Problems solved by technology

Method (1) can only detect the sunlight illuminance within the range of about 180° in the direction of the front of the vehicle and the range obliquely above the front windshield. When the sun is behind or on the side of the vehicle, the sunlight sensor cannot accurately detect the sunlight intensity, so the method (1) There is a small measurement range and it is difficult to accurately detect the sunlight illuminance of the car, which easily leads to the problem of high temperature inside the car and affects the comfort of the car environment

Although method (2) can detect the intensity of sunlight affected by each of the four seats of the vehicle, it uses a large number of sunlight sensors and high cost, so it is not suitable for promotion
