anti-lock braking system, or ABS is a safety system which prevents the wheels on a motor vehicle from locking up (or ceasing to rotate) while braking.A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively with the road surface as directed by driver steering inputs. While ABS offers improved vehicle control, and may decrease stopping distances on dry and especially slippery surfaces, it can also increase braking distance on loose sur ....etc

Technician Guidelines for Antilock Braking Systems



AN INTRODUCTION TO ANTILOCK BRAKING

This section reviews several basic antilock braking system
(ABS) concepts. When you complete this section, you should be
able to answer the following questions:
• What is an ABS?
• Why are antilock braking systems (ABSs) standard on
most new commercial vehicles?
• How does an ABS work?
• What are the major features and benefits of ABSs?
• How should I drive an ABS-equipped vehicle during a
road test?

AUTOMATED CAR BRAKING SYSTEM USING FUZZY LOGIC CONTROLLER

ABSTRACT
This paper deals with a Fuzzy Logic Controller (FLC) for an automated car
braking system. The response of the system will be simulated by using Fuzzy Logic
Toolbox in MATLAB and PID controller. The purpose of this controller is to brake a
car when the car approaches for an obstacle at a specific range. For this, the Fuzzy
Logic Controller is design using the Fuzzy Logic Toolbox in MATLAB. The system
uses four rules and three membership function. The two pa ....etc

Use your trusty multimeter to check continuity through wheel speed sensors.
This sensor has a value of about 1.5 K ohms.

FUZZY LOGIC IN CONTROL DESIGN ANTI-LOCK BRAKE SYSTEM

ABSTRACT:
In recent years fuzzy logic control techniques have been applied to a wide range of systems. Many electronic control systems in the automotive industry such as automatic transmissions, engine control and Anti-lock Brake Systems (ABS) realize superior characteristics through the use of fuzzy logic based control rather than traditional control algorithms. ABS is implemented in automobiles to ensure optimal vehicle control and minimal stopping distances durin ....etc

ABSTRACT

A fuzzy logic based automatic braking system is proposed using distance and relative speed sensors as inputs and brake-pressure as output. Heuristic rules have been developed and implemented. The controller monitors the deceleration rate of the vehicle to prevent tire lock-up and the consequent loss of directional stability. The system offers the flexibility of setting the separation distance. Simulation of the controller for driving into a stationary or moving objects shows that the system is performing well. It also uses an anti l ....etc
