The communication matrix (or CAN matrix) is a table structure, essentially defining the following:
•Which ECU sends which message under which conditions and with which cycle time.
•Which ECU receives a certain message/signal.
•Which signals are included in a message as well as their interpretation, i.e. how hexadecimal sizes are converted into physical or logical sizes.
•Which identifier and thus priorities messages have.
