Nissan's car that stops you drink and driving

ITWorld quotes
The first attempts to detect alcohol in the driver's sweat. After drinking, a certain amount of alcohol escapes the body in perspiration and this can be picked up by sensitive detectors if they are in proximity with the driver.

One of the four sensors in the car is on the gear shift lever. As this has to be touched in order to start driving, the system can stop the car from being started if alcohol is detected.

A second system in the car uses a camera mounted in front of the driver to monitor eye movement. If the driver is drowsy it triggers the seat belt to tighten and this movement will hopefully snap the driver out of their drowsiness or prompt them to take a rest. A voice alert also sounds and a message pops up on the navigation screen.

In the prototype the system quickly administered a few jerks to the seat belt when the driver simulated tiredness.

A third system monitors the path of the vehicle to ensure it's traveling in a straight line and not weaving about the road, as is common with a drunken driver. This also triggers the voice and visual alerts and pulls the seat belt when signs of drunk driving or drowsiness are detected.




When the detected alcohol level is above a preset threshold - which can be at or below the legal limit - the system locks the transmission, immobilising the car.

A “drink-driving” voice alert is sounded via the car’s satellite navigation system.

The technology would be attractive to drivers with a drink problem, and could bring benefits to others in the form of low insurance premiums.
