Japanese Car Keeps Watch for Drunk Drivers
The cars sensors check odors inside the car and monitor a drivers sweat for traces of alcohol.An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit.The air odor sensors are fixed firmly and deeply in the driver
Other carmakers have developed similar detection systems. For example,Swedens Volvo2 has developed a breathalyzer attached to a cars seat belt that drivers must blow into before the engine will start.
The car technology is still in development,but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology. For example,if the gear-shift sensor was bypassed by a passenger using it instead of the driver,the facial recognition system would still be used, Doi says.Nissan has no specific timetable for marketing the system,but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.
In the UK4,some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs.
