Electrical system: fewer cables and more functions

When the AT/AD cabs were introduced, the Trakker range also adopted combined electronic management and multiplex (the so-called MUX system). Commands received from switches and pushbuttons, and information transmitted by the sensors, are all gathered by electronic control units which transform them into digital signals. These then circulate within a single cable – the CAN (Controller Area Network) line – to the control appliances and indicators (luminous telltales, analogue instruments and digital displays). Use of CAN lines allows the number of functions to be increased (for example, information about vehicle operation, speed or consumption), halving the number of cables, fuses and relays. Even the diagnostic capacity is increased. Outfitters are provided with a control unit on the chassis to which they can connect the necessary terminals for lights, the PTO controls and the current for the dashboard telltales.

Engine management can be adapted to the characteristics of the PTO, thanks to a special DMI control unit (optional), which can be programmed using the Modus system. This solution allows up to three Power Take Offs to be managed on a single vehicle.
The MUX cables are divided into four sections: chassis and organs, cab, onboard instruments, radio and communications. The CAN-bus multiplex line of the chassis was the first to be installed on Iveco vehicles (the EuroStar Cursor 10 in 1999 and the EuroTrakker Cursor in 2000). It links the engine, automated gearbox, Intarder retarder, EBL braking system, anti-theft device and tachograph sensor. Five years of experience with customers have proven the advantages of this new technology and the competence acquired by Iveco in this field.
