Which network was designed for time triggered safety critical use?

  • A.Ethernet
  • B.A time triggered protocol with a fixed schedule and redundant channels, developed for chassis and steering systems
  • C.FlexRay
  • D.The controller area network, whose priority arbitration guarantees the delivery of every message within its deadline

Answer: C

FlexRay allocates fixed time slots and offers two redundant channels at ten megabits. The last option describes exactly that, which makes it a correct and more descriptive version of the same answer. The shared behaviour explains why these belong together and the differences explain why both exist. Checking which component actually carries the load settles most questions of this kind at once. Framing the question as which quantity the change acts upon makes the answer follow without calculation.
