What is the difference between Traction control and ABS??

Answer 1

Traction control (also called ASR - Acceleration Slip Regulation) is a system built into some cars that is intended to treat wheelspin (I originally said "prevent" here but that's not strictly the case). There are several ways in which this system operates, but they all work to actively slow down wheels that are spinning more quickly than the others. Virtually all traction control systems "piggyback" the car's Anti-Lock Braking System since it has a component infrastructure that serves the ends of both. Before continuing a description of traction control, a brief description of ABS is probably appropriate:

Anti-Lock Brakes are intended to give the driver more control under heavy braking situations. If one were to be more specific, ABS systems are meant to enable the driver to steer the vehicle while braking heavily. Before ABS was introduced, if a driver were to brake heavily the wheels of the car would often lock up (they would stop rotating altogether, even though the car was still moving) and it would slide. Control is virtually impossible in such situations and given that heavy braking is almost always used to avoid some hazard, a way of retaining some control would be most useful.

abs i antilock brake system   locks and they are allot more better traction control

Answer 3

ABS (antilock brake system) just does what it says. It prevents locking your brakes on sudden and vigorous braking. It consist of the cars on board computer (ECU) and the hydraulic system. Each wheel has an electronic sensor that senses the wheels rotational speed. When brakes are applied, the sensors measures the speed on all wheels. When a wheel decelerates quicker than the rest (indicating that it's about to lock), the ECU direct the valves in the hydraulic system to open thereby releasing pressure to the brake until the speed of that wheel matches the speed of the rest of the wheels. ABS gives you more control of your car during slippery situations. Without ABS when braking, if your front wheels lock-up, steering control is lost and your car will continue in the same path as before you attempted to brake. With ABS, the brakes are pumped/applied electronically at about 15 x per second so that rotation on your front wheels is not lost and steering the car in the intended direction is also attained.

Traction control is used to prevent your drive wheel/tires from losing grip on acceleration. This is obtained different ways. One way consists of the same components as the ABS since ABS is traction control as well. Smoking your tire during acceleration looks cool but this actually slows your car down. With traction control, the ECU directs the hydraulics to apply the brakes on the wheel that's spinning during acceleration until tire grip is obtained. The other way is, the ECU in your car actually modifies the fuel entering the engine and use the transmission to actually slow the drive wheels until grip is obtained.

So there you go....hope I helped.

Answer 4

Traction control keeps your wheels from spinning during acceleration.  They use similar technology as ABS.  That is, they apply quick braking action to halt a free spinning wheel.  They do this either with ABS, or with halting fuel flow to the engine.

ABS is to stop the wheel from skidding (when hitting the brakes).  It releases the wheel when it stops to allow for rotation.
