Many studies have established links between driver drowsiness and road accidents, presenting driver drowsiness as one of the main factors leading to accidents. In this paper, the authors present the first stages of the development of a real-time driving monitor that will detect driver drowsiness based on certain parameters of the driving pattern (steering wheel movements, speed of the vehicle, etc.). A new approach was implemented, which allows real-time acquisition and processing of data, as well as drowsiness detection. This approach is based on digital signal processing tools, specifically on digital filtering. Preliminary tests to evaluate the performance of the system were conducted. The tests consisted of two periods of highway driving: one during the morning, and one in the evening. A statistical comparison shows important differences between both driving periods, allowing the authors to conclude about the good performance of their first prototype of the system.
