[sci.electronics] Automotive networks

rhaar@gmr.com (Robert L. Haar) (04/23/91)

I have received a number of request for postings on the topic of
automotive datalinks, so I will put together some articles. I will
post them to rec.autos.tech and sci.electronics. I will alos cross
post the initial ones to comp.protocols.misc to see if there is
interest there as well.

The first article will give an overview of the SAE activities in
vehicle networks. This will include some historical background,
descriptions of current activities, and pointers to appropriate
literature. Later articles will describe each of the three 
communications categories as defined by SAE. Depending on interest
and my schedule, I my put together something on the specialized
diagnostic interface that is being developed.

I will be doing this as an individual and a member of SAE, not
in any official capacity as an employee of General Motors. The 
information will be all publically available, but not also
published at this time. There will be areas of proprietary
information that I will not be able to discuss.

At G.M. Research Laboratories, we do basic and long-term applied
research on topics related to the automotive industry. The things 
I work on may influence the design of vehicles in production five 
to ten years from now. But I am not involved with current products.

Please do not ask me to help you fix your car. I have neither
the time nor the knowledge to do this. I am only an amateur
mechanic, like most of the people on these net groups.

My purpose in posting these articles is to spread information. The
automotive engineering community tends to be rather closed in,
with little contact with the academic research world. But the
rapid development of computer controls in vehicles is bringing
up fundamental issues of distributed control systems. In the
same way the automotive engineers know little of current academic
research, the computer science research community knows little
of the problems in real world engineering.

That's all for now. More in a day or two.
