Design, Fabrication, and Testing of an Automated Pneumatic Braking Program with the Use of Ultrasonic Sensor

Vehicle collision or most commonly known as vehicular accident often occurs almost everywhere in the country and reasons for such accidents are endless but not being able to break on time was a major one. This research was about testing the performance of an automated pneumatic braking program, which can initiate sudden or gradual braking automatically using an ultrasonic sensor, by integrating the program to a fabricated prototype which consists of a pneumatic system and a mounted tire neglecting its weight and friction. Several tests on the prototype were conducted to present various types of braking which can be triggered depending on the distance between the obstacle and the ultrasonic sensor, and the obstacle will always be placed in front of the prototype to simulate a frontal collision. The outcome of the study showed that the ultrasonic sensor, speed sensor, and braking pressure are accurate as shown in the series of trials showing little difference between the actual values and the gathered values, and the calculated stopping distance during braking was less than the distance between the objects which means that no collision is bound to happen. As such, the overall result of the performance test showed that it was feasible to achieve a safe braking operation.
