4.3 CAN Bus
The development of CAN began when more and more electronic devices were implemented into modern
motor vehicles. All this means more safety and more comfort for the driver. Examples of such devices
include engine management systems, active control systems such as ABS, gear control, lighting control,
ventilation, air conditioning and central locking.
4-8: Communication via cable connection
To improve the behavior of the vehicle even further, it was necessary for the different control systems
(and their sensors) to exchange information. This was usually done by discrete interconnection of the
different systems (i.e. point to point wiring). The requirement for information exchange has then grown
to such an extent that a cable network with a length of up to several miles and many connectors was
required. This produced growing problems concerning material cost, production time and reliability.
The solution to this problem was the connection of the control systems via a serial bus system. This bus
had to fulfill some special requirements due to its usage in a vehicle. With the use of CAN, point-to-point
wiring is replaced by one serial bus Each module is given a CAN Bus connection. This is accomplished
by adding some CAN-specific hardware to each control unit that provides the ’rules’ or protocol for
transmitting- and receiving information via the bus.
