Nissan alcohol test

Nissan is testing a new way to prevent drunk drivers from driving a car. The car he just knows that the driver is drunk and does not allow such drivers to leave.

Nissan has come up with interesting devices that allow drivers to drive drunk. The front seats are mounted sensors that can detect alcohol fumes inside the cabin. If the electronics is measured at pre-programmed limit value, the navigation system screen will appear warning and notify the same information and voice signals. In the event that the driver tries to trick the control electronics intensive ventilation, the car is still equipped with a sensor in sweat gear lever. The analysis of sweat driver's hand again, then the system can determine whether the driver can drive. If not, again triggers a warning voice through the speakers and hang sorting.

The system is tested yet, so we do not know how to maintain the car when the driver under the influence of all open windows and use gloves. However, it seems that the system takes account of and is a great chance that the driver does not pass this trick. Above is the dashboard camera, complemented by software for the analysis of human faces. The program according to head movements and blinking eyes, remembers the state of alertness of a particular person. If the system detects signs of fatigue, a warning voice, and the seat belt will automatically attract the driver to increase his attention. The should be a warning device from unintentionally leaving the lane.

The device is still only a prototype, which is mounted to Nissan Fuga sedan. Many brands, however, already uses a variety of protective equipment against drunk drivers. For example. Saab has developed a somewhat less sophisticated system called - AlcoKey . Automaker Volvo system again Alcoguard . With the kind of stick, which communicates with the vehicle control unit, each driver before driving to a breath test. In the case of a positive finding of alcohol in the breath can not start the car.
