Drinking control method for drivers

Abstract

The invention provides a drinking control method for drivers. The method can be used for quickly and accurately judging whether the drivers drink or not before driving and automatically turning off automobile ignition relays under the condition that the detection result shows that drivers drink excessively, thereby preventing zonked drivers from driving after drinking; and the method simultaneously solves the problem of long preheating time of an alcohol sensor and can be used for accurately judging whether an artificially blowing phenomenon exists or not. The invention not only greatly shortens the preheating time of the alcohol sensor to enable the whole process of alcohol detection before driving to be convenient and quick, but also overcomes the defects that the traditional similar equipment needs to be provided with a microphone additionally, so that the cost is increased, and the use of the microphone can cause wrong judgment. In addition, the invention also provides a subsequent continuous detection method for monitoring alcohol content in the ambient air in automobiles in real time during driving after automobiles are started, thereby effectively avoiding the phenomenon that another person who does not drink helps a drunk driver to start an automobile and then the drunk driver drives the automobile, and once the alcohol content in the ambient air in automobile exceeds the standard, proper warning information can be sent, so that the safety is enhanced, and the potential hidden danger is avoided.

Description

【Technical field】 [0001] The invention relates to a motor vehicle driving safety guarantee method, in particular to a driver drinking control method that can accurately detect whether the driver is drinking excessively, and perform ignition prohibition or alarm reminder accordingly. 【Background technique】 [0002] The traffic rules clearly stipulate that drivers are not allowed to drive after drinking, but incidents of drunk driving have been repeatedly prohibited. Drivers and friends often find it difficult to "not drink at all" due to various reasons such as hospitality, but drivers drink Afterwards, they often cannot objectively judge whether their level of drunkenness can still drive, which causes drunk driving accidents to happen from time to time. Thus if there is a method to quantitatively test the driver's alcohol consumption, when the alcohol content exceeds the standard, by cutting off the ignition device of the motor vehicle or reminding the driver to warn the dri...

Problems solved by technology

For this reason, in recent years there have also been driver drinking controllers related to controlling drunken driving. However, these products have many defects in practical applications. The main factor of their defects is that they all directly use ethanol sensors as The detection element, and the ethanol sensor has the disadvantages of long warm-up time (recovery time), sensor parameters are affected by the use environment, and great volatility, which leads to the alcohol detection of the drinking controller that directly uses the ethanol sensor as the detection element in actual application. Inaccurate values ​​lead to misjudgment, low reliability and practicability, and the existing technology does not solve this problem well

In addition, most of the existing drinking controllers are equipped with electret microphones, which can be used to obtain the sound caused by people blowing air through the microphone to judge whether to start the test. Therefore, the practical application is also slightly insufficient

In addition, the point start control function equipped with the drinking controller to realize the control of the motor vehicle ignition device also overlaps with the corresponding function in the anti-theft alarm in the basic configuration of the car, which not only causes unnecessary waste, but also increases the normal use of the motor vehicle. failure rate
