Driver drowsiness detection is a car safety technology that helps prevent accidents caused by the driver getting drowsy. With the advent increase in accidents on motor vehicles due to drowsiness, driver drowsiness detection is an efficient car safety technology that helps prevent such accidents.

The driver drowsiness detection is based on an algorithm, which begins recording the driver’s steering behavior the moment the trip begins. It then recognizes changes over the course of long trips, and thus also the driver’s level of fatigue. Typical signs of waning concentration are phases during which the driver is barely steering, combined with slight, yet quick and abrupt steering movements to keep the car on the track.

Technologies that determine Driver Drowsiness Detection

Here are some technologies:

Steering pattern monitoring

Primarily uses steering input from the 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. If you would like to know how this works, check this article.

Physiological measurement

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

Advantages of Driver Drowsiness Detection

The following are some advantages:

• This system can be used in factories to alert the workers.
• If found drowsy, the alarm system gets activated and the driver is alerted.
• If there is any obstacles it is alerted the driver.
• This system can also be used for railway drivers.
• The life of the driver can be saved by alerting him using the alarm system.
• The speed of the vehicle can be controlled.
• Traffic management can be maintained by reducing accidents.
• Practically applicable

Conclusion

This drowsiness detection system helps the drivers a lot and prevents many road accidents that are caused due to drowsiness.
