How does the Engine and Brake Traction Control Systems (EBTCS) manage wheel spin during acceleration?

Engine and Brake Traction Control Systems (EBTCS) are designed to prevent wheel spin during acceleration, which can occur when a vehicle's tires lose grip on the road surface. The correct answer highlights that EBTCS employs both applying brake pressure and adjusting engine torque to achieve effective traction control.

When a wheel begins to spin, the system can apply brake pressure to that particular wheel, reducing its speed and helping it regain traction. This action is vital for maintaining stability and control, particularly in slippery conditions. Simultaneously, the system may also adjust engine torque by reducing the power sent to the wheels. By lowering the engine's output, it prevents excessive power from overwhelming the tires, ensuring that they maintain contact with the road.

This dual approach is essential because it provides a more comprehensive solution to managing wheel spin, allowing for smoother and safer acceleration. Other choices, while they may suggest actions that could happen individually, do not encapsulate the full functionality of EBTCS as effectively as the selected answer does.
