Pedestrian Safety Device in Automobiles

Abstract

Usually in designing a car, focus is specifically on the safety of the passengers in the car as a vital part, but the safety of the pedestrians on the road is also equally important. In this paper, we throw light on the safety of pedestrians on the road. The objective is achieved by analysis of the safety system employed to avoid the collision of vehicles and with pedestrians using warning signals and automatic braking of the vehicle is done in the worst-case scenario. The safety system employed here uses image processing for pedestrian identification and automatic braking. Initially by using an image processing algorithm the camera fixed in the vehicle monitors the obstacles in front of the automobiles. If a human is at a vulnerable distance the vehicle is stopped by using automatic braking. In case of emergency, if pedestrians approach the vehicle suddenly, then with the help of a servo motor the controller pulls out the airbag from the designed surface of the automobile hood. By using this technique, we assure the safety of pedestrians by reducing the number of accidents without affecting the structure and the design of the automobiles. The proposed work has been implemented into a prototype.
