Traction control systems are related to anti-lock braking systems and use the same technology. When the system senses a loss of traction on one side, it can independently feather the brake attached to that wheel to bring the spinning under control. Advanced systems can even adjust the amount of torque supplied by the engine on the fly, ensuring that every tire retains its grip on the road even when road conditions are uneven.
