Automobile TC stands for automobile traction control system, which can improve the passability of vehicles. When ABS anti-lock braking system detects that some wheels slip, it will brake the slipping wheels to avoid the loss of traction on the slipping wheels. When the system is working, the yellow TC indicator light on the instrument flashes to give the driver a hint.

Traction control system, also known as tracking control system. When a car brakes on a smooth road, the wheels will slip and even the direction will be out of control. Similarly, when auto start or sudden acceleration occurs, the driving wheels may slip, and there will be a danger that the direction will be out of control on smooth roads such as ice and snow. Traction control system is designed to solve this problem.

Traction control system relies on electronic sensors to detect that the speed of the driven wheel is lower than that of the driving wheel (which is the characteristic of skidding), and it will send a signal to adjust the ignition time, reduce the valve opening, reduce the throttle, downshift or brake the wheel to stop skidding.

Traction control system can not only improve driving stability, but also improve acceleration and climbing ability.
