What does the TC logo on Buick cars mean?

[DeReed]

TC on a car stands for Traction Control System, which improves the vehicle's passability. When the ABS anti-lock braking system detects that some wheels are slipping, it applies braking to the slipping wheels to prevent loss of traction. When TC is displayed on the car's dashboard, it indicates that the vehicle's traction control system is active. The relevant introduction of the traction control system is as follows: Introduction to Traction Control System: The control device of the traction control system is a computer that monitors the speed of the four wheels and the steering angle of the steering wheel. The Traction Control System, abbreviated as TCS, is also known as ASR or TRC. Its function is to ensure that the car obtains optimal traction under various driving conditions. Working Principle of Traction Control System: It can control the vehicle's traction by reducing the throttle opening to decrease engine power or by using the brake to control wheel slip. In cars equipped with ASR, the mechanical connection from the accelerator pedal to the throttle valve of the gasoline engine is replaced by an electronic throttle control device.
