Does "error frames" on CAN bus delay/ impair the communication?

QUESTION

Does "error frames" on CAN bus delay/ impair the communication?

Asked 2022-Feb-28 at 14:41

The quote below is from a document by Texas Instruments.

The error frame is a special message that violates the formatting rules of a CAN message. It is transmitted when a node detects an error in a message, and causes all other nodes in the network to send an error frame as well. The original transmitter then automatically retransmits the message. An elaborate system of error counters in the CAN controller ensures that a node cannot tie up a bus by repeatedly transmitting error frames.

Also, this wikipedia page provides more information on error frames.

As mentioned in several answers (link1, link2), CAN bus is half-duplex, that is, the nodes cannot transmit and receive data at the same time.

In general, a modern car contains more than 50 ECUs (nodes) on a CAN network. In case of an error, " if " the nodes would send error frames one after another, the CAN BUS would be occupied for a quite long time.

So, what do I miss here? Do the nodes send their error frames at the same time/ simultaneously and the hardware solves that issue? What happens if a node transmitted a different or corrupted error frame?

...

A node that repeatedly sends active error frames first goes into the "Warning" state and then later into the "Bus Off" state. This prevents a broken node from becoming a "bubbling idiot".
