Problems solved by technology

This design makes the driver have to add an action every time before starting the car, making the operation troublesome and time-consuming
[0004] In addition, in the existing technology, the judgment of the driver or the passenger drinking is not clear enough
Only the U.S. patent allows the driver to hold the mouthpiece of the breathalyzer to exclude the influence of the occupants on the test, but this is unhygienic and inconvenient

Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] The main idea of ​​the present invention is that after the drunk driver gets on the car and closes the car door, inserts the key and turns half a stroke to make the vehicle circuit conduction, the alcohol detector installed behind the steering wheel starts to detect whether the alcohol content in the air in the car is Exceeding the standard, if the detection does not exceed the standard, the electronic control unit (ECU) in the vehicle is allowed to start the engine, and the driver continues to turn the key to start; If it is detected that the driver’s reaction time is slow, it means that the driver is drinking, and the engine cannot be started under the control of the ECU, otherwise it can be started.

Abstract

The present invention discloses a method of detecting the alcohol for the vehicle and a system. An alcohol detecting device and a reaction time detecting device are respectively connected with the car electronic control unit, wherein, the alcohol detecting device detects the alcohol concentration of the air in the vehicle and sends the detection result to the car electronic control unit, and the reaction time detecting device detects the reaction time of the vehicle driver and sends the result to the car electronic control unit; the car electronic control unit judges whether the alcohol concentration exceeds the standard and whether the reaction time is too long. By adopting the technic proposal, the present invention can conveniently and wholesomely detect whether the vehicle driver is in drunk driving, and take safety measures.

Description

technical field [0001] The invention relates to the technical field of vehicle safety assurance, in particular to a method and system for vehicle alcohol detection. Background technique [0002] With the development of the economy and the advancement of science, motor vehicles continue to enter the family, making our country a world automobile power. But the ensuing car safety issues are also highlighted. According to statistics, about 100,000 people die in traffic accidents every year in my country, which is one of the countries with the largest number of casualties in the world. On average, one person dies under the wheel every 45 seconds. Cars, while facilitating people's travel and accelerating social progress, have also virtually become another killer of human beings. The reason is not that my country has the largest number of cars in the world, but that the people's awareness of traffic safety is relatively weak. Drunken driving is an important manifestation of this...
