ULTRASONIC CAR BRAKING SYSTEM MOHD SHAHRIZAN B. SAHRI UNIVERSITI MALAYSIA PAHANG ABSTRACT An ultrasonic car braking system includes; an ultrasonic wave emitter provided in a front portion of an automatic braking car producing and emitting ultrasonic waves frontward in a predetermined distance in front of the car. Ultrasonic receiver also formed in a front portion of the car operatively receiving a reflective ultrasonic wave signal as reflected by obstacles positioned within the pre-determined distance in front of the automatic braking car. The reflected wave (detection pulse) was measured to get the distance between the vehicle and the obstacle. Then PIC is used to control servo motor based on detection pulse information to push pedal brake to brake the car intermittently for automatically braking the car for a safe braking purpose. CHAPTER 1 INTRODUCTION 1.1 BACKGROUND Driving is a compulsory activity for most people. People use their car to move from one place to other place. The number of vehicle is increasing day by day. It is produced tacked tightly and risk to accident. Nowadays, the numbers of accident is so high and uncertainly. Accident will occurs every time and every where and cause worst damage, serious injury and dead. These accidents are mostly cause by delay of the driver to hit the brake. This project is designed to develop a new system that can solve this problem where drivers may not brake manually but the vehicles can stop automatically due to obstacles. This project is about a system that can control braking system for safety. Using ultrasonic as a ranging sensor, its function based on ultrasonic wave. After transmit by transmitter, the wave can reflect when obstacle detected and receive by receiver. The main target for this project is, car cans automatically braking due to obstacles when the sensor senses the obstacles. The braking
