| Change in what we call the system and some components: 1. Overall system is MPX 2. CAN, BEAN… are types of MPX systems 3. Sub BUS now a Branch |
| Multiplex communication is used to reduce the quantity of wire harness by transmitting each signal via a serial communication line. |
| - Features of Topology - Bus - The transmitting ECU output signal through a common communication line and the receiving ECUs input data through a common communication line. Ring Style - A signal that is output by a transmitting ECU circles the ring and returns to its original ECU. Star Style - Only Master ECU can send a signal to other ECUs. - The ECUs cannot establish communication with other ECUs without passing through the master ECU. |
