technology which helps prevent accidents caused by the driver 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.


Technology

Various technologies can be used to try to detect driver drowsiness.


Steering pattern monitoring

Primarily uses steering input from electric power steering system. Monitoring a driver this way only works as long as a driver actually steers a vehicle actively instead of using an automatic lane-keeping system.


Vehicle position in lane monitoring

Uses a lane monitoring camera. Monitoring a driver this way only works as long as a driver actually steers a vehicle actively instead of using an automatic lane-keeping system.


Driver eye/face monitoring

Uses computer vision to observe the driver's face, either using a built-in camera or on mobile devices.


Physiological measurement

Requires body sensors to measure parameters like brain activity, heart rate, skin conductance, muscle activity, head movements etc...

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. * COREforTech - Measuring physiological signs of drowsiness allows CORE for Tech ™ to get very early signs of fatigue and act accordingly


Regulation

In European Union, regulation (EU) 2019/2144 regulates the driver monitoring system.
