Drunk driving prevention safety system and detection method thereof

Abstract

The invention provides a drunk driving prevention safety system and a detection method thereof. The system comprises a vehicle door detection module, a vehicle seat detection module, an alcohol concentration detection module and a control module, wherein the vehicle door detection module detects whether a vehicle door is opened or not and transmits a vehicle door opening signal to the control module; the vehicle seat detection module detects whether force is applied to a driving seat and transmits a signal about that the force is applied to the driving seat to the control module; the alcohol concentration detection module detects the alcohol concentration and transmits a concentration signal to the control module; the control module comprises a comparison unit and a trigger unit; the control module compares the received concentration signal with a first concentration threshold value of the comparison unit; when the alcohol concentration is larger than the first concentration threshold value, the trigger unit adjusts the concentration threshold value to a second concentration threshold value, and the second concentration threshold value is larger than the first concentration threshold value; and the control module compares the received concentration signal with the second concentration threshold value of the comparison unit, and if the alcohol concentration exceeds the second concentration threshold value, the vehicle is not started.

Description

technical field [0001] The invention relates to the technical field of vehicle control modules, in particular to an anti-drinking driving safety system and a detection method thereof. Background technique [0002] With the continuous development of today's society, more and more people have bought cars, although this has brought a lot of convenience to life, but a series of problems have followed. Accidents caused by drunk driving and fatigue driving are a major problem facing society today. [0003] Although the traffic police department has intensified its supervision on drunk driving detection, the alcohol content tester is a passive inspection device, that is, when the traffic police finds that the driver is abnormal and suspects whether he has drunk too much, the alcohol test is carried out. Therefore, there are also many "fish that slipped through the net", and a lot of manpower, material resources and financial resources need to be invested. And some studies on prev...

AI Technical Summary

Problems solved by technology

The system does not determine whether the excess alcohol is from the tester or from the high alcohol level in the vehicle itself

A series of fraudulent behaviors such as finding someone to replace the alcohol tester in the car are also prone to occur.

At present, there is also a phenomenon that the alcohol tester misjudgments the driver because of eating alcoholic food.

[0004] The current domestic research on fatigue driving is still in the exploration of theories and methods, without systematic standards and perfect solutions

In addition, the research and development of the anti-drowsiness safety system generally stays in the prevention of alarms, and does not involve how to relieve driver fatigue.

[0005] At present, the safety systems for anti-drowsiness and anti-drinking driving are relatively independent, which also leads to the complexity of vehicle safety systems, waste of resources, and the installation of related safety systems increases the purchase cost of buyers.
