Vehicle Automation Based on Driver Fatigue

This paper purposes an idea to develop a system to detect driver fatigue and issue a timely warning signal. The fatigue can be some medical ailments or a drowsy feeling in the night. A large number of accidents occur due to the driver’s fatigue and hence this system will be helpful in preventing many accidents. This system will monitor the driver’s eyes using a web camera and measure the pressure applied in the steering wheel using grip sensors around the steering wheel. The system uses an algorithm in MATLAB to detect the driver fatigue and issue a beacon. If driver felt drowsy there is possibility of sudden acceleration or deacceleration and hence we can judge this by plotting a graph in time domain and when all the three input variables shows a possibility of fatigue at one moment then a signal is given in form of text in the display. Moreover, the driver might reduce the pressure applied in the steering wheel or take his hand out of the steering wheel when he begins to sleep. The system will give a beacon in the form of sound. The deactivation of the warning signal is controlled by a deactivation switch which is present in the steering wheel.
