Drunken driving prevention device

Abstract

The invention discloses a drunken driving prevention device which comprises a steering wheel, an ethanol detection sensor, a telecommunication line, an engine controller and an instrument alarm lamp, wherein the ethanol detection sensor is arranged on the steering wheel and connected with the engine controller and the instrument alarm lamp through the telecommunication line. The invention avoids the occurrence of drunken driving from the source, greatly reduces the drunken driving accident rate, can avoid from being outtricked by a driver in a breath holding manner compared with the traditional authorized drunken driving prevention invention and also prevent vehicle speed dip caused by simply cutting an oil line, and other manners during high-speed driving, thereby effectively avoiding vicious accidents of rear-end, and the like caused by the vehicle speed dip.

Description

technical field [0001] The invention relates to a vehicle-mounted device, in particular to an anti-drunk driving device used in automobiles. Background technique [0002] At present, the main implementation methods of vehicle-mounted anti-drunk driving equipment are as follows: 1. Install alcohol detection equipment in the car. If alcohol is found to exceed the standard before the car is started, the starter motor relay will be disconnected, so that the car cannot be started; 2. Alcohol detection equipment is installed in the car equipment, periodically detect the alcohol in the car, if it exceeds the standard, disconnect the starter motor relay, regardless of whether the car has been started; 3. Install alcohol detection equipment in the car, and periodically detect the alcohol in the car. Is the car started. Method 1 has the following problems: If the drunk driver holds his breath, he can fool the alcohol detection equipment and start the car to drive normally. The secon...

AI Technical Summary

Problems solved by technology

Method 1 has the following problems: If a drunk driver holds his breath, he can fool the alcohol detection equipment and start the car to drive normally

Method 2 has the following problems: Drunk drivers use methods such as holding their breath to start the car, even if the system detects that the driver is drunk and then turns off the starter motor, the car cannot be turned off

Because once the car is started, the engine does not need to use the starter motor, so whether the starter motor relay is turned off will not stop the car

The third method has the following problems: If drunk driving is found during the running of the car, the oil circuit will be cut off immediately, which will lead to a sudden drop in vehicle speed. When driving at high speed, various vicious traffic accidents such as rear-end collisions are very likely to occur. It is not good enough to cause new traffic accidents
