LOCAL INTERCONNECT NETWORK
Electrical System
The familiar CAN bus (two-wire bus) is
supplemented by the following bus systems:
– LIN bus (single-wire data bus)
– MOST bus (optical data bus)
– Bluetooth
TM (wireless data bus)
LIN bus
LIN stands for Local Interconnect Network.
Local Interconnect means that all control
units are located within a limited structural
space (e.g. roof). This is also referred to as
"local sub-system".
Data are exchanged between the individual
LIN bus systems in a vehicle by one control
unit in each case using the CAN data bus.
The LIN bus system is a single-wire data bus.
The wire has a basic colour (violet) and a code
colour.
The wire cross-section is 0.35 mm
2. A screen is
not necessary.
The system permits data exchange between
one LIN master control unit and up to 16 LIN
slave control units.

Design and operation of the LIN bus
are described in SSP 286 – New data bus
systems.

Electrical System
BluetoothTM
BluetoothTM is an internationally standardised
remote control data interface.
It permits control or monitoring of even
minute units using radio waves.
The primary aim when developing this new
type of interface was to create a wireless
alternative to cable links, which used to be
susceptible to interference and inconvenient
and frequently featured incompatible
connectors.
More and more manufacturers are making use
of "Bluetooth
TM" radio wave technology for
example for wireless interconnection of
notebook and mobile phone accessories.
As initiator and main contributor to the
development of this new transmission
technology, the Swedish company Ericsson
chose the name "Bluetooth".
The name originates from the Viking king
Harald Blåtand II (Danish, literally meaning
"Blue Tooth"), who lived around 1000 years ago
in Denmark and Norway.
Motor vehicle applications
