Conversely, if the ECU detects a wheel turning significantly faster than the others, brake hydraulic pressure to the wheel is increased so the braking force isĪ go kart is a small four wheeled vehicle basically used of traditional kart racing and amusement purpose. The ECU constantly monitors the rotational speed of each wheel if it detects a wheel rotating significantly slower than the others, a condition indicative of impending wheel lock, it actuates the valves to reduce hydraulic pressure to the brake at the affected wheel, thus reducing the braking force on that wheel the wheel then turns faster. Typically ABS includes a central electronic control unit (ECU), four wheel speed sensors, and at least two hydraulic valves within the brake hydraulics. Operation The anti-lock brake controller is also known as the CAB (Controller Anti-lock Brake). This function, depending on its specific capabilities and implementation, is known as electronic brakeforce distribution (EBD), traction control system, emergency brake assist, or electronic stability control (ESC). Recent versions not only prevent wheel lock under braking, but also electronically control the front-to-rear brake bias.
Since initial widespread use in production cars, anti-lock braking systems have been improved considerably. ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces however, on loose gravel or snow-covered surfaces, ABS can significantly increase braking distance, although still improving vehicle steering control.

It does this at a much faster rate and with better control than many drivers could manage. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems.

At 65% slip in conventional braking, CoF is 0.69whereas in ABS, CoF is 0.854 and in TCS, CoF is 0.812.Īn anti-lock braking system or anti-skid braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. In conventional braking at 100%, total wheel lock occurs, while in ABS & TCS at 65% slip traction is generally regained. The results from the experiments suggest that wheel slip is highest at the peak braking force and although ABS & TCS improve traction and control, it increases the stopping distance of a vehicle proportionally, which can be dangerous in certain scenarios. The obtained data and facts from the experiment is then compared and analysed. In the following project, an experimental setup to imitate tire road interactions is made to collect data of wheel slip and coefficient of friction under conventional braking, Antilock braking system and Traction control system. In this present work, we study and compare the performance of vehicles under different road conditions using conventional braking, anti-lock braking system and traction control system, and study the relation of coefficient of friction and wheel slip ratio for different road conditions. Vehicles with high speed require an equally efficient traction and braking system. Therefore, the need of the hour is to reengineer and refine existing automotive systems to better suit the requirement of a modern day vehicles. Modern day automotive technology is advancing at a rapid rate resulting in vehicles with outstanding performance and speed. If brake system fails the red LED glows and the buzzer do not beep when the brakes are applied. When the brake is applied in order to slow down or to stop the vehicle the green LED blinks and the piezo buzzer beeps for about one second if the brake system is accurate and working properly. The brake failure indicator circuit is a circuit that monitors constantly of the condition of brakes and provides an audio visual indication. Now a days, accidents are occurring due to lot of reasons, the one of the main reason is brake failure, it caused to due to poor maintenance, improper use and product defect, in order to safe guard the valuable human for accident the accident monitoring of brake is very important issue in automobile.
The main objective of this project is to continuously monitor the braking system at each and every time during the operation of the vehicle. To meet the need of growing population economic, effective and reliable control of machines as well as their control system is necessary. Today, Machines are widely controlled by automated control system.
