What is the traction control system(TCS)?

A traction control system (TCS) is designed to prevent loss of traction of driven road wheels. TCS is activated when throttle input and engine torque are mismatched to road surface conditions.

Basic Idea of Traction Control

The basic idea behind the need for a traction control system is the loss of road grip that compromises steering control and stability of vehicles because of the difference in traction of the drive wheels.

When do we need it?

•  Traction control is used as a performance enhancement, allowing maximum traction under acceleration without wheel spin. When accelerating out of a turn, it keeps the tires at an optimal slip ratio.
• Traction control is not just used for improving acceleration under slippery conditions. It can also help a driver to corner more safely. If too much throttle is applied during cornering, the driven wheels will lose traction and slide sideways. This occurs as understeer in front-wheel drive vehicles and oversteer in rear-wheel drive vehicles. Traction control can prevent this from happening by limiting power to the wheels. It cannot increase the limits of grip available and is used only to decrease the effect of driver error or compensate for a driver's inability to react quickly enough to wheel slip.
• Traction control has traditionally been a safety feature in premium high-performance cars, which otherwise need sensitive throttle input to prevent spinning driven wheels when accelerating, especially in wet, icy, or snowy conditions. In recent years, traction control systems have become widely available in non-performance cars, minivans, and light trucks and in some small hatchbacks.

How can I Understand Traction Control is on or off?/Is it safe to drive with traction control light on?

It is only safe to drive with the TCS light on if it appears when you are losing traction: it means the system is engaging. Driving without traction control can make your vehicle susceptible to spinning out and sliding around on the road. ... Driving with your TCS Light on can be dangerous.
