THE FLORENCE CAN ARCHITECTURE The Florence architecture permits the exchange of information between the various ECU’s through different levels of telecommunication networks. The networks are the following:
Ö Ö Ö Ö Ö Ö
C-CAN Network I-CAN Network (M139 only, used for TV and data communication ) B-CAN Network K Network (serial-line for diagnostics of the C-CAN nodes) A-BUS Network W-BUS Network(serial-line connecting the Body Computer and the Bosch Motronic for recovery of the immobilizer)
The complete structure of the FLORENCE network is illustrated by the following figure that represent the Maserati Quattroporte, and it comprises three different levels of network for CAN communication: •
The C-CAN Network for the dynamical control of the vehicle’s powertrain (high speed network)
•
The B-CAN Network for the comfort functions of the vehicle’s bodywork (low speed network)
•
The I-CAN Network (Maserati Quattroporte only) for the data communication and the TV - the infotainment system
The C-CAN e B-CAN networks are interconnected through a gateway for the transfer of common information located inside the Body Computer Node (NBC). The abbreviations of the names of the nodes in the two vehicles are presented in the table.
