Get to Known Drunk Driving Prevention System

Now a days road accidents are the  major issue  facing all over the world. More than 37,000 deaths happen because of  vehicle collisions. You need to know that drunk driving is fatal. This is because of the nature of the job – driving involves proper  ordination between the brain and muscular system. In a drunk driver the the coordination is poor or fails to happen, which might result in fatalities. In view of this reality, manufacturers have come up with a new technology. We'll discuss it briefly in this article.

How drunk driving prevention system works
The drunk driving prevention system is equipped with three types of monitoring systems. They are

• Detection using alcohol odor sensors
• Detection using  monitoring system
• Detection from the drivers behavior

Detection using alcohol odor sensors

• In this is system, a high sensitivity alcohol sensors are built in the steering wheel to detect the presence of  alcohol on drivers hand as he/ she is attempting to start the car.
• Through a  high sensitivity sensor, the level of the alcohol is detected and if the alcohol level exceeds the acceptable level, it automatically switches off the transmission system.
• An alert or message is sent to the driver through the navigation system.
• One of the additional features of the alcohol odor sensor,  is that these are incorporated in the seat of the drivers and the passenger to detect the level of alcohol inside the car.
• If the alcohol level exceeds the predefined level, it sens the alert or message through the navigation system monitor.
• It also sends the information and tightens the seat belt around the driver.
• While fixing alcohol odor, make sure that it should detect within a short range. Else, there would be a problem of halting car while you are going near by a wine shop.

Detection using monitoring system
In this is system, a camera is fixed on the instrumental cluster, or directly in front of driving seat.
The camera monitors the facial expression of the driver.
It is used to calibrate the driver's state of consciousness.
It detects the state of driver through the blinking of the driver's eye.
When the camera detects the drowsiness of driver.
A sensor is arranged to the camera, it sends voice and message alerts through navigation system.
It also alerts the seat belt mechanism.
The seat belt mechanism immediately tightens the seat belt around the driver.

Detection from the drivers behavior

• In this system, The sensor detects the state of driver and behavior of driving.
• The sensors senses if the vehicle is drifting out  from it lane.
• The sensor identifies the signs of detraction.
• If the vehicles is distracted from its driving lane, with the help of the navigation system it sends noise and message alerts.
• It also sends the information to the seat belt mechanism, alerting to tighten it around the driver.

Advantages of drunken drive prevention system

• The driver cannot start the vehicle, if the alcohol level exceeds the acceptable level .
• The high sensitivity  sensors  detects the alcohol directly
• This sensors are simple in construction.
• They detect the level of alcohol more accurately.
