TractionTraction Control SystemTypes of TRAC System

INTRODUCTION:

HISTORY:

4-wheel driveDifferentialsAntilock Braking SystemTRAC System

Differentials: Advantages:

Power to most traction Simple in Action Wheel locking

Disadvantages: Wear out Cost to build. Special lubricants.

LITERATURE:

LITERATURE:

4-wheel Drive Systems Advantages:

Reducing slip No delay No Driver intervention required

Disadvantages: More hardware Not economic Performance drop

LITERATURE

Anti lock Braking System:Advantages:

Wheel locking is avoided.Sudden throttle control.

Disadvantages:Not effective at cornering.Maintenance issues.Not effective at Skidding.

TRAC WHEEL SPEED CONTROL:

wheel speed control against time

BENEFITS OF TRACTION CONTROL:

Avoiding accidentsSudden twists and turnsSlippage of the wheelsStopping distancesDriving a powerful carMost gripping.

APPLICATIONS:

In road carsIn race carsIn motorcyclesIn off road vehiclessafety

DISADVANTAGES:

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