Which braking system is described as an automated braking system?

• A. Conventional
• B. Hydraulic
• C. ABS (automated braking system)
• D. Pneumatic

Answer: (C)

Automated braking systems automatically adjust braking force to prevent wheel lock and keep the vehicle steerable during heavy braking. The anti-lock braking system does this by using wheel speed sensors and an electronic control unit to detect when a wheel is about to skid. When lockup is possible, it rapidly reduces and then re-applies brake pressure at each wheel, cycling many times per second. This automatic modulation is what makes it an automated braking system, helping the driver maintain control even under hard braking.

The other terms describe basic ways to apply braking rather than automate it: conventional brakes rely on the driver’s input to create hydraulic pressure, hydraulic refers to the fluid-based method of transmitting that pressure, and pneumatic involves air brakes used on many heavy vehicles. None of those inherently describe automatic modulation like ABS does.
