How Does Traction Control Work?

Developed ABS traction control systems

Traction control is an automotive safety feature designed to help your car’s wheels grip on low-traction surfaces such as slippery roads due to rain. When the tires begin to slip, the traction control system engages and the driver is able to maintain control of his vehicle. If, under the same conditions, a vehicle without traction control tries to accelerate, the wheels may spin. The vehicle will then fail to accelerate and may move unpredictably to the left or to the right because the wheels no longer hold the road.

To achieve the goal of reducing tire slippage, traction control systems use electronic sensors, similar to the better known anti-lock braking systems (ABS). They can also use sensors and electronic controls to limit the amount of power delivered to the driver when road conditions are dangerous.

Traction control systems cannot create traction where there is no traction, they can only improve existing traction. The traction control won’t help on nearly frictionless surfaces like ice.

What is traction control?

If you’ve ever been in a car that spins under hard acceleration, it probably doesn’t have a working Traction Control System (TCS). Just as ABS is designed to prevent wheelspin during braking, traction control is designed to prevent wheelspin during acceleration. These systems are in fact two sides of the same coin and even share several components.

Traction control has become increasingly common in recent years, but the technology is a relatively new innovation. Before the invention of electronic traction control, there were a number of pioneering technologies.

The first attempts to create traction control systems were made in the 1930s. These early systems were called limited slip differentials because all the hardware was in the differential. No electronics were involved, so these systems had to sense the lack of traction and transfer power mechanically.

In the 1970s, General Motors produced some of the first electronic traction control systems. These systems were able to modulate engine power when a lack of traction was detected, but were notoriously unreliable.

A related technology, electronic stability control, is now essential equipment in cars sold in the United States and the European Union. Since many electronic stability systems include traction control, these regulations mean your next car is increasingly likely to come with traction control.

How Traction Control Works

Traction control systems work like a sort of reverse anti-lock braking system. They use the same sensors to determine if one of the wheels is losing traction, but these systems look for wheel spin during acceleration rather than deceleration.

If a traction control system detects that a wheel is spinning, it can take a number of corrective actions. If a wheel needs to be slowed down, the TCS can take a hit on the brakes, just like the ABS.

However, traction control systems can exert some management over engine operations. If necessary, the TCS can often reduce the fuel or spark supply to one or more cylinders. On vehicles using a practice throttle, the TCS may also close the throttle to reduce engine power.

What is the advantage of traction control?

Maintaining traction on all four wheels is essential to maintaining control of your vehicle. If they come loose during acceleration, the vehicle may slide into a skid that you cannot recover from.

In these conditions, it is necessary either to wait for the vehicle to regain grip, or to cut the gas. These methods work, but a TCS has a much more granular level of control over motor and brake operations.

Traction control is no excuse for reckless driving, but it provides an extra layer of protection. If you often drive in wet or icy conditions, traction control can be very useful.

Quick acceleration is sometimes necessary when merging with road traffic, crossing busy roads and in other situations where going off the road could cause an accident. Traction control is extremely useful when you absolutely need that kind of quick acceleration.

Is traction control still useful?

Traction control systems are great if you’re driving on wet or icy roads, but they have their limitations. If your vehicle comes to a complete stop on slippery ice or heavy snow, traction control is probably unnecessary.

These systems can send an appropriate amount of power to each wheel, but it won’t help if all of your wheels are spinning freely. In such cases, you need to provide the wheels with something they can really grip.

Traction control systems can help you maintain control when cornering and assist you when accelerating. If you turn too fast, your drive wheels will tend to lose traction with the road surface.

Depending on whether you have a front or rear wheel drive vehicle, this can cause oversteer or understeer. If your vehicle has TCS, the traction wheels have a better chance of maintaining traction.

When is traction control useful and how do you use it?

Traction control is not really something you should consider using. It engages when needed. Your vehicle may have the ability to turn traction control on or off, so if you have the ability to drive in a situation where poor traction is likely, you’ll want to make sure it’s turned on. .

Some common situations where traction control helps include:

  • Trying to start or accelerate from a stop when light rain makes the road very slippery. Without traction control, your tires can spin, causing your vehicle to sway in an unexpected direction instead of accelerating.
  • Attempt to accelerate while going up an incline with an unpaved road surface. Without traction control, your tires can spin and cause you to lose your forward momentum. Your vehicle can then slide downhill or even fall to the side.
  • From a complete stop at a traffic light on an icy road with vehicles approaching from behind. Without traction control, oncoming vehicles could overtake you when your wheels spin. On the icy road, they may not stop later and crash into your vehicle.

In each of these situations, there is some traction on the road surface, so the traction control system can use it to help you start or keep you moving.

Is it safe to drive with the TCS light on?

In most cases, an illuminated TCS light means the system is not working. This means that if you find yourself in a bad situation on slippery roads, you cannot trust it. It’s generally safe to drive, but you have to be more careful about how fast you accelerate.

Depending on your vehicle, the TCS warning light may also come on when the system is on. In these cases, it usually turns off when traction is restored. Since traction control systems often work seamlessly, the illumination of that little light may be the only clue you might be slipping.

Traction Control Systems Are ABS Evolved

Traction control is a car safety feature that’s designed to help the wheels of your car grip low-traction surfaces like rain-slick roads. When the tires start to slip, the traction control system kicks in, and the driver is able to maintain control of their vehicle. If a vehicle without traction control attempts to accelerate under those same circumstances, the wheels may slip. The vehicle will then fail to accelerate, and may move unpredictably to the left or right as the wheels are no longer gripping the road.

To accomplish the goal of reducing tire slippage, traction control systems use electronic sensors in a similar manner to more familiar anti-lock brake (ABS) systems. They can also use electronic sensors and controls to limit the amount of power delivery that’s available to the driver when road conditions are dangerous.

Traction control systems cannot create traction where there is none, they can only improve existing traction. On nearly friction-less surfaces, like ice, traction control will not help.
What Is Traction Control?

If you’ve ever been in a car that skidded out during heavy acceleration, it probably wasn’t equipped with a functioning traction control system (TCS). In the same way that ABS is designed to prevent skids during braking, traction control is meant to prevent skids during acceleration. These systems are essentially two sides of the same coin, and they even share a number of components.

Traction control isn’t an excuse for careless driving, but it does provide an extra layer of protection. If you frequently drive in wet or icy conditions, traction control can really come in handy.

Rapid acceleration is sometimes necessary when merging with freeway traffic, crossing busy roads, and in other situations where spinning out could result in an accident. When you absolutely need that kind of rapid acceleration, traction control is extremely useful.

Does Traction Control Always Help?

Traction control systems are great if you’re driving on a road that’s wet or icy, but they do have limitations. If your vehicle is completely stopped on slick ice or in heavy snow, traction control will most likely be useless.

These systems can send an appropriate amount of power to each wheel, but that won’t help if all of your wheels are freewheeling. In those circumstances, you’ll need to provide the wheels with something they can actually grip.

In addition to providing assistance during acceleration, traction control systems can also help you maintain control while cornering. If you take a turn too fast, your drive wheels will tend to lose traction with the road surface.

Depending on whether you have a front or rear wheel drive vehicle, that can result in either oversteer or understeer. If your vehicle is equipped with TCS, the drive wheels stand a better chance of maintaining traction.

Starting from a complete stop on an icy road at a traffic light with vehicles approaching from behind. Without traction control, the approaching vehicles may overtake you as your wheels slip. On the icy roadway, they may then be unable to stop and hit your vehicle.

In each of these cases, there is some traction with the road surface, so the traction control system is able to leverage that to help you start moving or keep you moving.

Is It Safe to Drive with the TCS Light On?

In most circumstances, an illuminated TCS light means that the system isn’t functioning. That means you won’t be able to rely on it if you find yourself in a bad situation on slick roads. It’s usually safe to drive the vehicle, but you’ll have to pay closer attention to how quickly you accelerate.

Depending on your vehicle, the TCS light may also illuminate whenever the system goes into action. In those cases, it will usually shut off when traction is restored. Since traction control systems usually operate transparently, the illumination of that little light may be the only hint that you were ever in danger of spinning out.
