How does the Toyota Active Traction Control TRC system work?

Model: Toyota Toyota Various

In this animation we see how the TRC system works on Toyota vehicles: it is a safety system that aims to prevent the slipping of the driving wheels during acceleration, especially on slippery surfaces such as ice, snow or wet asphalt. In practice, the TRC helps to maintain optimal traction on the road, improving the stability and safety of the vehicle. The TRC works by constantly monitoring the rotation speed of each wheel. If it detects that one or more wheels are slipping faster than the others, it intervenes to reduce their power. In this way, traction is restored and the vehicle's grip is maintained. To carry out its work, the TRC relies on: wheel speed sensors, which constantly monitor their rotation; electronic control unit that receives data from the sensors and decides which actions to take; braking system that is used to slow down the slipping wheels; engine control that reduces power to the wheels losing grip.
