Driver drowsiness detection is a car safety technology which prevents accidents when the driver is getting drowsy. Various studies have suggested that around 20% of all road accidents are fatigue-related, up to 50% on certain roads.[1]

Some of the current systems learn driver patterns and can detect when a driver is becoming drowsy.


  • Ford:Driver Alert[2]
  • Mercedes-Benz: Attention Assist[3] In 2009, Mercedes-Benz unveiled a system called Attention Assist which monitors the driver's fatigue level and drowsiness based on his/her driving inputs. It issues a visual and audible alarm to alert the driver if he or she is too drowsy to continue driving.
  • Volkswagen: Fatigue detection system[4]
  • Volvo Cars: Driver Alert Control[5] In 2007, Volvo Cars launched the world's first Driver Drowsiness Detection system, Driver Alert Control. The system monitors the car's movements and assesses whether the vehicle is being driven in a controlled or uncontrolled way. If the system detects a high risk of the driver being drowsy, the driver is alerted via an audible signal. Also, a text message appears in the car's information display, alerting him or her with a coffee cup symbol to take a break. Additionally, the driver can continuously retrieve driving information from the car's trip computer. The starting-point is five bars. The less consistent the driving, the fewer bars remain.
  • Anti Sleep Pilot - Danish device that can be fitted to any vehicle, uses a combination of accelerometers and reaction tests.[6]
  • Vigo - Smart Bluetooth headset that detects signs of drowsiness through the eyes and head motion, and uses a combination of light, sound and vibration to alert the user.[7]
