Driver drowsiness detection
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.
Some of the current systems learn driver patterns and can detect when a driver is becoming drowsy.
- DADS:' DADS : Driver Alertness Detection System 
- BMW:Active Driving Assistant
- Ford:Driver Alert
- Mazda:Lane Departure Warning System
- Mercedes-Benz: Attention Assist 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.
- Subaru: EyeSight Driver Assist
- Volkswagen: Fatigue detection system
- Volvo Cars: Driver Alert Control 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.
- 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.
