Stuttgart, Germany – Mercedes-Benz has announced its new Attention Assist, a support system that is able to recognize driver fatigue at an early stage and warn the driver that a break is required. The system will enter series production next spring.
The company said that studies indicate around 25 per cent of all serious crashes are caused by overtired drivers, a percentage more significant than driving under the influence of alcohol. The situation is worse during long-distance journeys in the dark or unchanging conditions at a constant cruising speed. After only four hours of non-stop driving, a driver’s reaction time can be 50 per cent longer. The risk of a crash is doubled after this length of time, and after six hours of driving it can be eight times as high.
The system monitors the driver’s behaviour, generating an individual driver profile which is constantly compared to a flow of sensor data, measuring vehicle speed, linear/lateral acceleration, steering wheel movements, turn signal and pedal operation, and a number of specific control operations and external influences, such as side winds or uneven road surfaces. If the system detects the driver is drowsy, it sounds an acoustic signal and flashes a warning in the instrument cluster.
