What type of system is used to prevent wheel lock during braking?

The antilock braking system (ABS) is specifically designed to prevent wheel lock during braking. When a driver applies brakes, especially in emergency situations, ABS monitors the speed of each wheel. If it detects that any wheel is about to lock up, meaning it would stop spinning entirely and skid, the system automatically modulates the brake pressure. By doing so, it allows the wheels to continue turning, thereby maintaining traction with the road surface. This process not only helps in stopping the vehicle more safely but also allows for better steering control while braking, which can prevent accidents.

The other systems mentioned have different primary functions. Traction control helps prevent wheel spin during acceleration, while stability control works to maintain vehicle stability during cornering or when skidding occurs. Emergency brake assist is aimed at providing additional braking force in critical situations but does not specifically address the issue of wheel lock during braking itself. Each system plays a vital role in vehicle safety, but for the specific task of preventing wheel lock during braking, ABS is the definitive solution.
