1. A TOPIC SEMINAR ON “TRACTION CONTROL SYSTEM” Presented by, Vijay S (4PS07ME093) P.E.S.C.E. Mandya

2. INTRODUCTION: Traction Traction Control System Types of TRAC System

3. HISTORY: 4-wheel drive Differentials Antilock Braking System TRAC System

4. Differentials: Advantages: Power to most traction Simple in Action Wheel locking Disadvantages: Wear out Cost to build. Special lubricants. LITERATURE:

6. Not economic

8. BLOCK DIAGRAM OF TRAC: PROCESS

9. CASE STUDIES: Limited slip differential 1971 - Buick division of GM “MaxTrac” Honda ST in 1992, Kawasaki Concours 14 in 2010 Mitsubishi's modern Active Skid and Traction Control 2006 “Theory of ground vehicles” - Prof. Jo Yung Wong, Carleton University.

10. SCOPE: Self learning systems Track conditions Tire condition Internal settings Desired TRAC control level

11. TRAC SYSTEM: TOYOTA SUPRA MARK IV

12. TRAC WHEEL SPEED CONTROL: wheel speed control against time

13. BENEFITS OF TRACTION CONTROL: Avoiding accidents Sudden twists and turns Slippage of the wheels Stopping distances Driving a powerful car Most gripping.

14. APPLICATIONS: In road cars In race cars In motorcycles In off road vehicles safety

15. DISADVANTAGES: wear on brake components. Holds performance driving. Allows 10 % wheel slip. Its banned in F1 racing.
