<p>The vehicle communication network contains a number of control units (1, 32, 33, 34), each with a communication interface (102, 103) (322, 323), etc., bus lines (41, 42) interconnecting the units to support two way communication, and a switching circuit (104) connecting to the bus line, where the majority of control units is in a single group utilising one communication protocol, and a second group uses a separate communication protocol. The switching circuit (104) separates these two groups of control units.</p> |
