The present invention relates to a driver drowsiness detection and alerting system comprising a plurality of marks in ring configuration around an exterior cylindrical surface of a vehicle's steering wheel column assembly, and an optical sensor assembly near the plurality of marks for detecting movement of the marks, the optical sensor assembly connected to a means for alerting the driver if the steering wheel does not move for a prescribed time period while the motor vehicle is moving, characterized in that the optical sensor assembly comprises a optical detector and a light emitter adjacent to each other. Additionally, the present invention relates to a kit of parts for such driver drowsiness detection and alerting system. La présente invention porte sur un système de détection et d'alerte de somnolence de conducteur, lequel système comprend une pluralité de marques sous une configuration annulaire autour d'une surface cylindrique extérieure d'un ensemble de colonne de volant de direction de véhicule, et un ensemble de capteur optique au voisinage de la pluralité de marques pour détecter un mouvement des marques, l'ensemble de capteur optique étant connecté à des moyens pour alerter le conducteur si le volant de direction ne bouge pas pendant une période de temps prescrite pendant que le véhicule se déplace, et lequel est caractérisé en ce que l'ensemble de capteur optique comprend un détecteur optique et un émetteur de lumière voisins l'un de l'autre. La présente invention porte également sur un ensemble de parties pour un tel système de détection et d'alerte de somnolence de conducteur.
