Practice question

What is the function of the Electronic Braking System (EBS) on modern heavy trucks?

  1. It automatically turns off the engine whenever the truck exceeds 50 km/h
  2. It replaces purely pneumatic pilot signals with millisecond electronic sensor signals to brake chambers, drastically shortening brake response latency, balancing pad wear, integrating ABS/ASR/ESP, and coordinating truck-trailer braking harmony
  3. It applies brakes only when the vehicle is stationary
  4. It replaces physical brake pads with virtual brake software

Answer: B — It replaces purely pneumatic pilot signals with millisecond electronic sensor signals to brake chambers, drastically shortening brake response latency, balancing pad wear, integrating ABS/ASR/ESP, and coordinating truck-trailer braking harmony
