What is TRAX and how does it work?

Find out what TRACS is in Volvo vehicles. How does the start assist system work in Swedish vehicles?

Modern cars have many systems and systems to help the driver in safe and comfortable driving. The TRACS system in Volvo vehicles is an example of a traction support solution. Find out how it works and when it's useful!

TRAX - what is it?

TRACS is an anti-skid system found in Volvo vehicles.. It is installed in models with all-wheel drive, which improves the grip of the car on dirt roads or slippery surfaces. It is worth knowing that the system is active when driving below 40 km/h. It then facilitates starting off by improving stability, hill climbing and improved acceleration.

How TRACS works

The TRACS system in Volvo vehicles uses wheel speed sensors to determine which wheels are starting to spin. This is followed by braking, which involves the components of the ABS system and the braking system. As a result, the opposite wheel works with more torque, which gives it more traction.. In this way, the driver can safely negotiate sections of the road, for example, covered with snow. TRACS works automatically and is activated when the engine is started.

How do other traction assistance systems work?

In modern cars, the installation of traction control is an absolute norm. Depending on the brand, they differ from each other, but use one or more of the following solutions, due to which they work relatively the same:

braking one of the wheels and transferring the opposite wheel to a higher torque;
instant throttle closing;
reduction of pressure in the turbine;
restriction of fuel supply to the engine cylinders.
