Functions and How Traction Control Works and Its Components

Traction control or Traction Control System (TCS) is a safety feature that has been around for some time.

Like other safety features, not many people are aware of the TCS feature. Even so, a car that has this feature is no doubt safe.

Although it has long been found, TCS is still a mandatory requirement for new cars built starting from 2011.

Now, more and more cars are using traction or traction to help increase safety because it is able to control traction and avoid the car from slipping.

What Is Traction Control?

So far, many accidents occur due to the driver losing control of the car. Things that can trigger this are slippery road conditions or improper driving maneuvers.

This situation can make the car skid and lose control. The traction control feature has a function to increase safety when something like this happens or while driving.

In simple terms, traction control is an electronic system that uses a sensor system.

Traction will get input from the anti-lock braking system (ABS) and the car's drive wheels to detect wheels that are losing traction, slipping or turning faster than other wheels.

This sensor is usually installed together with the ABS sensor.

Traction Control Function

A car that has great power and good looks remains uncontrollable when the tires are spinning without traction.

Loss of traction is a condition where when the car turns a corner or the tires spin but the car is stopped.

At times like this the traction control function works on the car, to prevent the wheels from slipping. In addition, the use of TCS can also ensure the car maintains grip even on low-friction surfaces.

Traction control itself is controlled automatically in the vehicle according to the input obtained.

When a wheel is caught abnormally, ABS will reduce the force on the wheel.

Even if the road surface is slippery, the TCS will restore traction to the car in all types of weather and road conditions. The following is an explanation of the traction control function.

Maintain Stability When Cornering

When the car makes a sharp turn until it slips, then all passengers will be panicked by what happened. This can be minimized with the traction control function on the car.

TCS is a feature that is used to prevent tires from slipping and slipping when road conditions are wet and when turning corners.

The usual traction feature is on the back of the latest car that ensures safety while driving and works automatically so that the driver does not need to do anything except press the button to activate the one near the steering wheel.

This feature will detect the traction on each wheel and then apply braking to the wheel experiencing it.

Helping Drivers When Turning

When you want to turn, the driver basically has to control 3 things at once, namely acceleration, braking and steering.

Controlling these three things at once is indeed quite difficult and complicated, especially if the driver who is driving is still new to the car.

TCS can help the driver do this by automatically braking each wheel so as to keep the car turning safely.

The TCS feature can adjust engine power so the wheels can maintain grip.

Braking performed by traction is not done arbitrarily but each wheel will be given its own brake force so that the brakes for each wheel are not as strong depending on their own cooling needs.

The sensor on the car's traction is in the stability control section which will assess how strong the brakes are needed on one wheel so that the car does not slip because the wheel suddenly stops.

The TCS of the car will be active for a moment when it will be cornering. The system will automatically provide grip on each wheel to brake with a certain force.

For example, when the vehicle is cornering at a high speed so that the car has the potential to slip, the traction owned by the vehicle stability control will slowly brake until the car can turn gently and safely.

The traction control system can also be activated when going out of a corner such as when the driver presses the gas pedal too quickly when exiting a corner so the car can bounce out of the way. Traction will brake gently and can return the car to the right track.

Traction Control System Components

The traction control system component has many parts, so it needs to be cared for so that the health of the car is maintained. Here are the components:

1.Wheel Speed ​​Sensor (WSS) or wheel speed sensor

The sensor is used to give a signal to the ABS and then to the ECU

2.Engine Control Unit (ECU)

The component that receives the signal from the WSS and gives the command signal to adjust the wheel speed.

3.Hydraulic unit

Pumps are used to lift liquids to generate pressure.

4.Electronic Throttle Control Actuator

Components to maintain temperature conditions and the car engine remains stable.

5.Fuel Injection and Ignition Control

Has the task of reducing the engine pump pressure slowly.

How Traction Control Works

The fundamental function of traction control is to detect when the tire can lose grip and start turning and then stop or slow down.

To do this, traction needs to use sensors from the ABS that can detect wheel locks during braking.

Unlike ABS, traction will look for one of the car's wheels that can spin faster than the other wheels indicating a loss of traction.

When the sensor reads that the tire does not have traction, the system will respond by slowing the wheel rotation, reducing power or both things can happen.

Traction uses the WSS system as a sensor to detect. So when the wheel traction is lost, the sensor will send a signal to the ECU to apply braking gradually to the rotating wheel and make the wheel get traction again.

Additional Safety Features

So the principles in traction control are used to add functionality to the other safety features of ABS. if there is one wheel that tends to move faster then traction will be active.

While the main input for controlling traction control is from the wheel speed sensor. The sensors continuously monitor the wheel speed at all times while the vehicle is moving and generate a signal that is proportional to the wheel speed.

By comparing wheel speeds, the ABS system can detect changes that indicate a wheel is losing traction, is stationary or turning. So when there is a slip on one of the wheels, the traction control will activate the brakes on the wheels that are spinning fast so that the wheels have the same rotation as the other wheels.
