Thank you very much.
Thanks for the introduction.
It's really a pleasure to be here and give this talk on cyberphysical systems.
So what I'm going to talk about is really joint work, as you might see, with several
people, both from Munich as well as from MIT as well as from a lot of other universities.
Okay, so I guess one question that might be of interest to all of you is what really are
cyberphysical systems?
This is a term that all of us have been hearing quite a lot since the last couple of years.
So I would not actually try to define cyberphysical systems because this is more complex.
So there are actually many, many interpretations or examples.
The first is network embedded systems.
Often these are referred to as cyberphysical systems.
Lot of people also refer to sensor network based systems.
Another term is also internet of things, commonly also used in Munich.
Also embedded control systems, and embedded control systems is kind of the definition
that I would assume for the purpose of this talk.
But what runs through all of these examples is that these are systems that where a computational
part closely interacts with a physical part, right?
So as you might guess, lots of examples like an air conditioner which has a control software
in it and tries to interact with the room and then maintain a certain temperature.
That would be, for example, a cyberphysical system.
But however, given that we are not too far away from Audi and also I come from the city
of BMW, we will actually use automotive as one of our running examples.
You also heard examples of automotive from the talk of Professor Wilhelm also, Professor
Glass gave this example of automotive.
So let's look at automotive once again.
So if you look at what has been happening in the domain of automotive over the last
15 to 20 years, we can see that this is the first picture on the top.
It essentially shows that most of the innovation today is no longer in the mechanical engineering
aspects of a car.
So like let's say 10 years ago, a car was primarily something of a subject that was
studied by the mechanical engineers.
But today at least the good news for us computer scientists and electrical engineers is that
most of the innovation is currently in the software and the electronics because the mechanical
aspects have more or less matured.
And the figure below shows you that the way, for example, memory and the number of ECUs
have been going on increasing.
And currently we have high-end cars that have almost 100 or even more electronic control
units.
Each of these ECUs have one to two processors.
So we are essentially talking about something like 100 to 200 processors inside the car.
And this is a computer that has one processor.
So it's almost like 100 to 200 such computers built inside the car.
And the question is, what are all of these processors doing?
So they are running several distributed control applications, applications coming from different
domains like safety-critical applications related to comfort, applications related to
driver assistance systems.
So this would be then a view of a modern car with a lot of processors that are, of course,
connected in some way through even kilometers long cables and running a lot of software
related to different control applications.
