Problems solved by technology

[0005] However, the automatic air conditioner has a disadvantage. When traveling long distances or when passengers need to rest, they often ignore the air conditioner to turn on. Especially in summer, when passengers close their eyes to rest or sleep, the air conditioner continues to supply air and cool according to the set temperature. Being continuously blown by the cold wind will cause wind chill and other physical discomforts, which will cause physical illness and cause passengers to complain

Embodiment 1

[0027] This embodiment provides a vehicle air conditioning control system, which includes a camera, a fatigue detection controller, and an air conditioning controller.

[0028] The camera is arranged on the rearview mirror in the car and is used to capture facial video information of passengers in the car. In this embodiment, the camera may be a wide-angle camera, and the captured passengers do not include the driver.

[0029] The camera is connected to the fatigue detection controller for transmitting the captured facial video information of the passenger to the fatigue detection controller, and the fatigue detection controller analyzes the fatigue degree of the passenger according to the video information to determine whether the passenger is Fatigue or whether you are going to sleep.

[0030] The fatigue detection controller is based on the DSP platform and includes 1 video input to access the camera. The fatigue detection of the passenger is realized by analyzing the video inform...

Embodiment 2

[0038] This embodiment provides a vehicle air conditioning control method, which is implemented based on the vehicle air conditioning control system of Embodiment 1, and includes:

[0039] S10. When the air conditioner controller of a certain independent temperature zone of the vehicle air conditioner is activated, the air conditioner starts to operate.

[0040] S20. Turn on the camera, shoot the video information of the independent temperature zone, and determine whether the passenger is tired or enter a sleep state according to the video information.

[0041] In this embodiment, the fatigue detection controller mainly performs real-time detection and measurement of passenger fatigue through the geometric characteristics of the eyeballs of the human eyelids, the gaze angle of the eyes and its dynamic changes, changes in the head position and direction, etc.; The relationship model between head characteristics and fatigue state, and judge whether the passenger is tired. Moreover, it...

Abstract

The invention discloses a vehicle air conditioner control system and method. The vehicle air conditioner control system comprises a camera, a fatigue detection controller and an air conditioner controller. The camera is arranged on a rearview mirror in a vehicle and is used for shooting face video information of a passenger in the vehicle; the camera is connected to the fatigue detection controller, and the fatigue detection controller analyzes the fatigue degree of the passenger according to the video information so as to judge whether the passenger is in a sleep state or not; the fatigue detection controller is in signal connection with the air conditioner controller; and the fatigue detection controller controls the air conditioner controller to operate in different modes according to whether the passenger is in the sleep state or not. According to the air conditioner control system for the vehicle, the working state of the air conditioner in the vehicle is controlled by judging whether the passenger in the vehicle is tired or is in the sleep state or not, and therefore the problems that in the sleep period, since the human body is continuously and directly blown by cold air physical, the passenger suffers from a cold or other discomfort, and diseases and passenger complaints are caused are solved.

Description

Technical field [0001] The invention relates to an air conditioning control system, in particular to a vehicle air conditioning control system. Background technique [0002] The on-board air conditioner on traditional cars or new energy vehicles can be controlled manually or automatically. After the automatic control function can achieve the temperature target set by the user, the air conditioner automatically adjusts the temperature and air volume to make the ambient temperature reach the set temperature condition. [0003] With the development of vehicle air-conditioning technology, there have been dual independent temperature zones, three independent temperature zones, and four independent temperature zones. The temperature conditions of each temperature zone in the vehicle can be adjusted and controlled independently. Temperature and air volume adjustment. [0004] With the increase of passenger car functions, the realization of humanized functions has gradually become one of th...
