Which statement about the anti skid system is correct?

• A. The anti skid signal is generated by the anti skid control unit
• B. The anti skid system uses only sensors and no control unit
• C. The anti skid system is unrelated to braking performance
• D. The anti skid control unit is optional

Answer: (A)

The key idea is that an anti-skid system relies on real-time sensing plus a control unit that decides how to modulate braking pressure. The anti skid signal is generated by the anti skid control unit because it processes data from wheel speed sensors, detects when a wheel is about to lock, and then issues a braking-pressure command to the hydraulic modulator to prevent skidding. This coordinated signal allows rapid pressure adjustments at each wheel, keeping the wheels rotating and preserving steering control. Without the control unit, sensors alone can’t produce the necessary braking adjustments, so the statement that the system uses only sensors isn’t correct. ABS is directly tied to braking performance, improving stability and stopping control on slippery surfaces, and the control unit is essential rather than optional.
