Sleep Detection and Alert System for Automobiles

Abstract

Driver sleep detection is a car safety technology which helps to prevent accidents when the driver gets drowsy. Various studies have suggested that around 20% of road accidents are fatigue related. A sleep alarm is used in a vehicle for detecting the condition indicative of the onset of sleepiness of a driver and for alerting the driver. An eye blink sensor is used to keep track of the driver’s eyelid motion. If the predefined safety conditions are not met, then the driver is alerted by producing an alarming sound from the inbuilt car speakers primarily. Secondly, a vibrating device is incorporated within the driver’s seat which activates when the conditions are not satisfied. Taking into account of the worst case scenario, that is, if the driver does not respond to any of these alarms then, using the proximity sensors, the obstacles around the vehicle is detected, and the brakes are automatically applied gradually.
