Abstract
A traction control system includes a master cylinder containing brake fluid, braking devices configured to apply braking force to associated wheels of the vehicle, a brake pedal operable by a driver of the vehicle to generate braking force by pressurizing the brake fluid, and an inlet valves for storing pressurized brake fluid to apply and temporarily hold a braking force at a slipping driven wheel. A method of providing traction control for a vehicle includes manually switching the vehicle from a normal operating mode to a traction control mode, sensing the slippage of a driven wheel, applying a braking force to the slipping driven wheel in response to a driver of the vehicle pressing a brake pedal, maintaining the braking force on the slipping driven wheel after the brake pedal is released, and gradually releasing the braking force as the slipping driven wheel gains traction.
