Electronics makes its own way – the fab 4 of fleet management

Multiplex net, already present on all heavy trucks, is now at its 2nd phase, i.e. easier communication outwards and data storage in one single format. Once upon a time, there was the so-called Controller area network, better known as Can bus or multiplex system. Later on, in the late Nineties, five of the most important European trucks contructors (Iveco, Man, Mercedes, Scania e Volvo), realized that those “telematic mini motorways” (i.e. multiplex nets) created on board of trucks needed something more which could allow the languages of different nets to be uniform: a standard.
