CAN Bus

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.

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.

Internet protocol properties

► Select Internet Protocol (TCP/IP) from the

list and click on Select Properties.

▪ Network card 1: Connection to the SR:

The network connection between the Vision

computer and station computer is established via the

LAN 1 connection of both computers. The network

address is pre-fixed and may not be changed.

IP-Address Vision computer: 192.168.255.252

This TCP/IP address can only be checked or

changed by the system administrator.

▪ Network card 2: Local Area Connection 2:

This connection is not used.

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.
