Bosch, leading supplier of automotive components in the world is developing a "sleep-o-meter" or drowsiness detection system aiming at enhancing active safety of the car. The low cost accessory would go into production later this year.
The system records how many times long pauses in steering-wheel movements are followed by sudden impulses. The attention system mixes those figures with other variables such as speed. If the condition becomes too frequent, it lights up a little coffee cup indicator, on the dash, to tell the driver it is time to rest, but more importantly, to stop to do so.
The system is already in use in some of the high end cars of Merecdes Benz and Volvo. Robert Bosch France President Guy Maugis said: "A number of vehicles are already equipped with steering-wheel angle sensors, which work with the ESP systems. It can easily, and cheaply, be used to detect whether or not the driver is falling asleep, which would in turn increase road safety.”
There has been increasing claims by the Traffic control organizations, majorly National Highway Traffic Security Association (NHTSA) and the German federal office saying that too many accidents were caused due to driver's fatique. The new drowsiness detection system is expected to bring down the number of accidents to a great extend.
