To prevent driven wheels from spinning, what method does Traction Control employ?

The method that Traction Control employs to prevent driven wheels from spinning primarily relies on modified ABS programming. Traction Control systems are designed to enhance vehicle stability and grip, especially under slippery conditions. When the system detects that one or more wheels are beginning to spin faster than the others, it can utilize the Anti-lock Braking System (ABS) to selectively apply brakes to the spinning wheels. This helps to transfer power to the wheels that have more traction, thereby maintaining grip and preventing loss of control.

By modifying the ABS programming, the Traction Control system can effectively intervene by applying brake pressure to the spinning wheels without affecting engine power significantly. This allows the vehicle to maintain forward momentum instead of allowing the wheels to spin freely, which could lead to a loss of control or difficulty in acceleration.

The other methods such as increased engine torque management, adjusting tire pressure, or downshift control do not directly relate to the responsive braking action that is characteristic of how Traction Control functions. Increased engine torque management might limit engine power but does not actively manage wheel spin through braking. Adjusting tire pressure affects overall vehicle dynamics but is not a real-time response to spinning wheels. Downshift control involves changing gears to improve traction, but this method doesn't directly engage with braking and
