CONTROL ON THE SAFE DISTANCE IN FRONT OF THE VEHICLE USING BRAKE FUZZY CONTROLLER

Abstract

In this paper, fuzzy brake controller is proposed. It is built by using the theory of fuzzy sets. The rules base of this controller are based on the previous knowledge and experiences in vehicle field.The working of controller reduces the vehicle velocity to achieve the safe distance in front between the vehicle and anther vehicle that traveling in front of it .So the controller prevents the slip in the tires during braking. The velocity error and distance error are used as inputs and brake force as control action output for the controller.The simulations of fuzzy controller with nonlinear brake vehicle model give acceptable responses for different ca
