Driver drowsiness detection is an advanced driver-assistance system (ADAS) that analyzes drivers’ alertness to avoid potential car accidents. When it detects signs of fatigue, it warns the driver to take a break.
Being part of the “second wave” of active safety systems, driver drowsiness detection uses cutting-edge technology such as sensors, lasers, cameras, GPS and radar. One of the most widespread technologies for detecting driver drowsiness is monitoring the steering input from the electric power steering system. However, it only has a result as long as a driver actively steers without using an automatic lane-keeping system.
Other technologies include driver’s eye and face motion monitoring using a built-in camera or a mobile device, and physiological monitoring using body sensors for measuring heart rate, brain activity, and other parameters.
As sleep deprivation is a significant cause of road accidents, the main purpose of this ADAS is to tackle this problem.
