What is Traction Control System?

After reading this, if i am correct, Rear wheel drive needs Traction control, Then what about front wheel drive system.

Even front wheel drive cars need traction to reduce understeer.

IMHO, RWD should even have stability control along with TC.

To differ slightly from Rachit's point, FWD cars usually stay more in control since the driven wheels are also the steered ones. So controlling the car becomes easier *in most situations* and traction control is not that required - by "in most situations" I mean situations for passenger car driving - where speed/racing is not paramount, roads are paved and so on. There are certain situations where FWD would fare worse than RWD and would benefit from traction control - however given that the front wheels already have weight over them (the engine sits over the wheels), the TC would be required on the rear wheels of the FWD car.

With RWD, the rear wheels DO NOT have the weight advantage of the engine sitting over them - so TC will greatly help here (one way is to simply place heavy weights - people - in the back of the car: That alone will improve traction).

I agree to this, and I never said its a must to have TC in FWD unless the engine power is much. But cars which possess more power need to have TC as a must. Your confusing TC with stability control. TC is a must in cars possessing powerful engines, not while steering but when the car starts off from rest. A FWD car will have more wheel spin than RWD car with the same power, during mpedal to metal driving from rest.

The weight of the car is transferred to the rear when accelerated, due to which the rear wheels have more traction than the front wheels and even with the engine at the front end, the FW spin.

The weight of the car shifts to the rear, hence they better traction than the FWD cars.

Hello,

im a second year mechanical engineering student, im goin to present a paper on TRACTION CONTROL, can some one explain me about the technical aspects of traction control and what kind of sensors are used for this??? i need this information urgently, pls help me..

little info here

@Binoy

I won't suggest that link to anyone who is working on automotives. That has no information on TC. And mixing sports cars with normal road cars is the biggest issue that we face today.

@P.Madhu....

Sensors used in TC are the wheel speed sensors which sense the speed of the wheels and send it to the ECU. The ECU calculates the speed and changes the power O/P to the driven wheel accordingly. 

Read my earlier posts in this thread, I have tried to define TC in simple words.
