Modern day automotive technology is advancing at a rapid rate resulting in vehicles with outstanding performance and speed. Therefore, the need of the hour is to reengineer and refine existing automotive systems to better suit the requirement of a modern day vehicles. Vehicles with high speed require an equally efficient traction and braking 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. 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. The obtained data and facts from the experiment is then compared and analysed. 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. In conventional braking at 100%, total wheel lock occurs, while in ABS & TCS at 65% slip traction is generally regained. At 65% slip in conventional braking, CoF is 0.69whereas in ABS, CoF is 0.854 and in TCS, CoF is 0.812.
