Design and performance Test of Auto Braking System Using Ultrasonic Sensor

Abstract

Recent years have seen a surge in purchasing of automobiles and with this increase in the number of automobiles have resulted in a considerable increase in accident rates. According to the Road Safety Organization, the number of road crashes and deaths last year were 27.14 percent and 22.74 percent higher than that of the previous year. On an average, 25 accidents take place every day in our country. Most of the accidents occur due to the delay of the driver to hit the brake. The control on the speed of vehicles can play a vital role in the reduction of number of accidents which can be achieved by the Auto Braking System (ABS). The main purpose of present Automobiles is being developed by more of electrical parts for efficient operation. The braking system was designed and applied on a car to make the driving process safety using embedded system design. So, in this project work braking system is developed such that when it is active it can apply brake depending upon the object sensed by the ultrasonic sensor. The ultrasonic sensor receives the reflected ultrasonic signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle and speed of vehicle. The microcontroller is used to control the braking of the vehicle based on the detection pulse information and apply brake to the car for safety purpose. A prototype was created and the structural analysis of the prototype was performed.
