Mercedes develops technology to keep fatigued drivers awake

Mercedes Benz is developing a new technology to detect fatigue to prevent drivers from falling asleep at the wheel.
Over the course of their investigations, the company's team of engineers, cyberneticists, mathematicians, computer scientists and psychologists is testing out a variety of methods for detecting driver fatigue as soon as it sets in. One of these techniques is the eye-blink observation method: an infrared camera directed at the driver's head permanently monitors the eye-blink frequency, enabling microsleep to be detected the instant the eyes stay closed for a certain period of time. A warning signal sounds in the car's cockpit in response.

In order to obtain objective indicators of fatigue, other physiological readings such as the electroencephalogram (EEG) are used. Yet another method is based on the analysis of dynamic driving data, such as steering or braking characteristics. One of the systems triggers an alarm if the driver does not move the steering wheel for a prolonged period of time..
