About this presentation
This presentation was

Matrix Multimedia Limited.
PowerPoint versions of this
presentation are available
on request.
Notes on the presentation
are included with each
slide down here:
What is CAN?
Controller Area Network
1Mb/s data rate
High reliability bus
Used for control in industrial and
Automotive applications
CAN is an open standard with many
variants
Advantages of CAN in automotive applications
Lower cost at vehicle construction
Increased flexibility and reusability of design
Reduces time to market
Facilitates drive by wire which reduces cost
further
Facilitates advanced features in vehicles
Enhances debug at point of service
Higher Level Protocols (HLP)
Startup procedures (e.g.are all the
nodes there?)
Addresses of particular nodes and
kind of messages
Layout of messages in data
System level error handling
Things about CAN
The protocol is designed to increase
integrity of the system
There is no hierarchy
It is designed for control – not
transmission of large blocks of data
At an basic level the protocol is quite
simple – the details are quite complex
