Information About

Traction Control




The intervention can consist of any, or all, of the following:

  • Retard or suppress the spark to one or more Cylinder s

  • Reduce fuel supply to one or more cylinders

  • Brake one or more wheels

  • Close the throttle, if the vehicle is fitted with drive by wire throttle.


The brake actuator, and the wheel speed sensors, are the same as that used for Anti-lock Braking System s.


USE OF TRACTION CONTROL

  • In road cars: Traction Control is used mainly as a safety feature in high-performance cars, which would otherwise need very sensitive throttle input to keep them from spinning when accelerating, especially in wet or snowy conditions. It is also used in off-road vehicles to enhance traction on loose surfaces.

  • In race cars: Traction Control is used as a performance enhancement, allowing maximum traction under acceleration without wheel spin. When accelerating out of turn, it keeps the tyres at the optimum Slip Angle .


It is widely thought that TC removes some skill and control from the driver. As such it is unpopular with many , which is relatively basic and does not have TC capabilities.
