Flex Ray

Why is the CAN protocol insufficient for modern automotive systems?

• It cannot connect multiple ECUs together.

• It has limited bandwidth and event-driven bus signals.

• It is too expensive to implement.

• It does not support fault-tolerant architecture.

What is one advantage of using dual-channel configurations in FlexRay?

• It increases bandwidth and provides data redundancy.

• It reduces the need for termination resistors.

• It simplifies the network topology.

• It eliminates the need for differential signaling.

How does the active star topology improve the reliability of a FlexRay network?

• By reducing the number of nodes in the network.

• By ensuring that all nodes share the same clock.

• By allowing other nodes to function if one branch fails.

• By eliminating the need for a central hub.

What ensures that a FlexRay node only accesses the bus during its allocated time?

• The daisy-chain topology.

• The dynamic segment.

• The bus guardian.

• The termination resistors.

What is the maximum data transmission speed of FlexRay?

• 0.5 megabits per second.

• 1 megabit per second.

• 5 megabits per second.

• 10 megabits per second.
