What is the difference between ABS and ATC?

The correct answer highlights the distinct functions of ABS (Antilock Braking System) and ATC (Traction Control) in vehicle safety and control.

ABS is designed to prevent the wheels from locking up during hard braking, allowing the driver to maintain steering control and preventing skidding. When brakes are applied forcefully, ABS rapidly pulses the brakes to ensure that the wheels keep turning, enabling the driver to maneuver even during emergencies.

On the other hand, ATC focuses on maintaining traction. When a driver accelerates, particularly on slippery surfaces, ATC helps distribute engine power to the wheels to prevent wheel spin. Instead of controlling braking, ATC helps manage how power is applied to ensure that the wheels remain engaged with the ground, thus maintaining better acceleration and stability.

Recognizing the different roles these systems play is crucial for understanding vehicle dynamics during various driving conditions.
