What does it mean when TRC control is turned off?

[VanIan]

TRC control being turned off means the vehicle's traction control system is deactivated. The primary function of TRC is to maintain driving stability. Its working principle is: the computer monitors the speed of all four wheels and the steering wheel angle. When excessive speed difference between driven and non-driven wheels is detected during acceleration, the computer sends signals to reduce fuel supply, thereby decreasing driving force and minimizing wheel slip rate. TRC control methods include brake torque control and engine torque control: Brake torque control applies braking force to wheels about to slip, dissipating excess engine torque through the brakes to maintain wheel slip within desired parameters, similar to ABS operation; Engine torque control optimizes driving torque to wheels based on road conditions by adjusting fuel injection quantity, ignition timing, and throttle opening.
