FlexRay
FlexRay is a scalable and fault-tolerant communication system for deter
-
ministic data exchange at high transfer rates. Using the time multiplex
procedure enables the creation of distributed systems with a highly mod
-
ular structure and high safety demands. The high bandwidth of 10 MBaud
on two channels plays its part in overcoming high network loads caused
by the increasing number of innovative electronic systems in modern vehi
-
cles.
The specifications of this communication system are issued by the FlexRay
Consortium, a committee which is supported by a large number of vehicle
manufacturers and suppliers worldwide.
FIBEX
FIBEX (

change) is an XML scheme based exchange format
used to describe the entire communication network in the vehicle. FIBEX
is designed for various types of network (CAN, LIN, MOST, FlexRay) and
includes information on bus architecture, signals, properties of the net
-
work nodes etc.
INTECRIO uses FIBEX files to coordinate software tools and ECUs and the
communication scheme dictated by the FlexRay cluster, i.e. the FIBEX file
defines, amongst other things, the signals. It also contains data to config
-
ure the hardware interface. The FIBEX files have to be made available by
the vehicle manufacturer.
