Automatic Car Braking System using Fuzzy Logic Controller with Environmental Factors

Driving a car is a complex task, it requires vigilance and experience. When the breaks are applied to a car at the right time and with the right amount of force it can prevent many accidents. A slow moving car or any stationary object on the road is an obstacle for the moving vehicle. It can be avoided by braking/lane change so that the car does not crash. Many factors are involved that effect the braking in cars. Several solutions have been implemented in cars to assist the driver by warning about the incoming obstacle. A device that helps the driver to break automatically is called Automatic Braking system (AUBS). It helps to reduce the accidents due to human error. The AUBS system is designed using a fuzzy logic controller. Apart from the obvious inputs such as speed of the car and the distance from the obstacle, several other important factors such as external conditions on road and the tires condition are considered in the proposed approach. The results showed that the Automatic braking system designed showed a reliable and efficient performance.
