Embodiment 1

[0020] A driving fatigue prevention system includes a carbon dioxide monitor and a vehicle controller installed in a vehicle. Increased temperature and lack of air circulation in the car are important causes of sleepiness. The carbon dioxide produced by breathing in the car will lead to changes in the concentration of carbon dioxide in the car, and the concentration of carbon dioxide will increase in a relatively closed environment. The present invention uses carbon dioxide to monitor the concentration of carbon dioxide in the vehicle. When the concentration of carbon dioxide reaches 1800-2000ppm, it indicates that the oxygen concentration in the vehicle is low and may lead to hypoxia, so a warning message is sent to the vehicle controller through the in-vehicle communication system.

[0021] The vehicle controller operates the air conditioner in the vehicle according to the received warning information, and adjusts the air circulation status in the vehicle, including:

Abstract

The invention relates to the technical field of automobiles, in particular to an anti-fatigue driving system. The anti-fatigue driving system comprises a carbon dioxide monitor and a vehicle controller which are arranged in a vehicle; the carbon dioxide monitor is used for monitoring the concentration of carbon dioxide in the vehicle under the running state and sending warning information to the vehicle controller when the concentration of the carbon dioxide is higher than a first preset value; the vehicle controller controls an air conditioner in the vehicle in an external circulation state according to the warning information. The anti-fatigue driving system has the advantages that the concentration of the carbon dioxide in the vehicle under the driving state is monitored in real time through the carbon dioxide monitor, when the concentration of the carbon dioxide in the vehicle reaches a threshold easily leading to brain hypoxia, the external circulation of the air conditioner is started through the vehicle controller, thereby preventing a driver from fatigue driving due to hypoxia.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a fatigue driving prevention system. Background technique [0002] With the vigorous development of the automobile industry, traffic incidents also occur frequently, most of which are caused by driver fatigue. [0003] Publication number CN108544902A, the invention patent application published on September 18, 2018 discloses an air-conditioning control device and method for preventing driver fatigue from driving. Remind the driver to cheer up by changing the temperature of the body, so as to prevent the driver from driving fatigue. However, the system only prevents the driver from driving fatigue by automatically switching the air-conditioning state when the anti-fatigue mode is turned on, which is not smart enough. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a fatigue driving prevention system, which i...
