Implementation of Hybrid Controlled Vehicle Braking Method for the Design of Collision Avoidance Systems In Vehicles

Abstract

According to data from the National Highway Transportation Safety Administration, human error is to blame for at least 90% of all car collisions. This information has intensified the focus on the design and development of collision avoidance systems in automobiles. This paper presents a semi-automated braking system to increase the accuracy of collision avoidance systems by reducing errors on the vehicle’s driver part. The methodology used combines the use of a microprocessor for analyzing data from sensors aided by servo motors, sending information to output devices for the alarm system and electric motors, and integrated circuits to implement hybridized engagement of vehicle brake. The braking system can be manually applied but can interfere and bring the vehicle to a halt once it has been determined that the driver has lost control of maneuvering the vehicle. The implemented system was able to determine the separation distances between automobiles and obstacles, give warning employing alarm set-up and engage braking at a minimum separation distance that is provided with an average response time of 0.86 s and a percentage error of 12.8% during operation.
