Standardisation & Technology

1 note

Have you ever experienced that your printer got stuck at a piece of paper? What if that happened every time you print? This course explains the importance of technical norms to which engineers abide to, so your printer works smoothly. Imagine that there were no standards. That is not easy, even if you try. The reason is that a lot of standards are very common to us and are with us for ages. But there are also new standards, new technical agreements, that are created rapidly every day. Did you ever ask yourself how under the hood of your mobile phone, messages are sent to other phones? Society would not be like it is today, if there were no technical agreements and or protocols on how things are working. This course explains how these technical specifications come into being and thus help you and but also society at large.

Welcome to this lecture on the future use and role of standards,

and now we are going to look into connected cars.

First, again we would like you to have a more,

some more feeling for what standards mean in the future,

and how are they going to be used.

But with cars let's say that the development

is the farthest when we are looking back at the privacy,

as I told you a few minutes ago or in the other lecture I told you,

and now we are going to see what connected cars,

and standardization has been doing on.

First, what is very important is that the development of

what we now call connected cars already started in the early 1990's.

Why? Because at that moment there was a development,

and developments going on,

on Intelligent Transport Systems,

namely smart infrastructure,

with all type of condensators on the road and things like that,

so to be able to guide the traffic.

Also known as green waves for instance in some countries;

to guide the traffic a bit more efficiently through, over the roads.

On the other hand, already in the end of the 1990's,

the beginning of the century,

On Board Diagnostic systems came, OBD,

which enabled car makers,

but also dealers to see and look inside of the car.

What happened on, and what the status was of different parts, and things like that.

Then about 10 years ago,

this OBD systems allowed to be

connected to the telecommunications, mobile telecommunications network.

In the beginning that was only used by

very high-end car makers like Mercedes or Audi or Chrysler,

so the high-end cars were trusted with these type of systems

that gave the On Board Diagnostics back to a network or to a data center.

From that developed the so-called within the European Union the ecosystem.

So, that when airbags for instance exploded,

then automatically the car will make a call to the emergency services,

and now let's say over the last four or five years standardization

and development of connected cars has come to a real high.

Everybody is taking this into account, and working on it,

but in reality the development started already more than 25 years ago.

So, here you see a lot of these On Board Diagnostics systems,

all type of different.

In the beginning they were connected with cables,

and now you can use them by using Bluetooth or Zigbee or some type of other connections.

So, that you can see your diagnostics on the car through an app on your mobile phone.

It can be made or put into almost any car,

as I show you here.

The ecosystem, I told you,

was evolved from these OBD systems into an emergency system,

and the legal environment that was created started in 2012,

and by 2018 all new cars that come into the market in

the European Union have to be entrusted with the ecosystem.

So, that in case of an emergency or needed the car,

in case nobody is able to respond or the driver

can call up emergency services because there's something wrong,

there has been an accident, things like that.

Now, let's see how connected cars came into being

in the sense that the car is really sending a whole bunch of information around,

and they are doing that by looking around their own environment,

influencing the infrastructure out of the car,

such as traffic lights when the car is approaching the light.

More intelligent ways of image processing as seen from inside of the car.

This data and image processing is

necessary to enable the coming of age of autonomous cars.

What a lot of people do not realize,

is that making cars connect to each other they need to connect to the infrastructure.

So, there is a huge amount of data coming out of a car,

to enable to register what's happening around it,

and also it needs to be secure,

so that the system cannot be hacked,

somebody else could take over your car.

A connected car is also probably a car,

that will in the end be automatically driven.

So, then again, a huge amount of data is coming out of a car.

The estimates at this moment are that's about 25 gigabyte per hour driving,

coming out of data,

coming out of the car the amount of data,

and that looks something like this.

There's a whole stream of zeros,

and ones coming into a database or into your mobile phone wherever it's going.

In Intelligent Transport Systems,

ISO, started in 1992,

and this group of different working groups on how standardization is going on,

is very much happening now,

and so the original division of the different working groups started out with 1992,

and when we look into the year 2017,

you can see here there's a booklet on where

the standardization at this moment within ISO,

and within the international intelligent transport system is working.

A huge bunch of work is being done in this area.

Then ISO is also very much into intelligent transport systems,

and they also have nice examples on how

these different forms of connection to the infrastructure,

connection to traffic lights, for instance,

but also being connected to pedestrians,

people that are walking around with a mobile phones.

So, that you can react on those,

so there's a whole bunch of roads,

data roads that need to be standardized,

and here you see one of the examples.

So, this is already an old standard out of 2003,

and the ISO has these standards available for you on their website.

Standardization organizations have to live off the money they can earn from the standard.

So, as you can see here on the screen,

to get the standard,

to really know what's in it,

you will have to pay.

So, that's one of their business models that you

will have to pay for the standards that are being produced.

IEEE had started already in the early days of WiFi,

for instance, with an acronym which is called WAVE,

namely Wireless Access for the Vehicular Environment

or a subset of the WiFi standardization which is a 802.11p.

This standard started the work on that started already I think in 2004,

and they agreed upon on more or less came into being in 2010.

When you look at the IEEE website at this moment,

and you look into what they are doing on WAVE,

which is more or less only the connection,

the wireless connection from outer car to its outside world.

But there is a lot more going on,

and this has been developed a special society

within IQ on Vehicular Environments and standardization.

So, if you would like to know more about that,

the developments are going very fast,

and over the last few months even,

new developments can be recorded from them.

So, please look on the website,

and see to gather more information from their environment.

When you look into how this looks,

you can see here for instance,

that the vehicle-to-vehicle communication is important of

course and when we talk about connected cars it's usually in that area.

But connection and connected cars need to communicate with the whole environment,

which entails a huge bunch of data that needs to come into being.

So, I hope to have invited you to

know and start to know more about how connected cars can,

and standards play a role,

and I hope also that you became curious.

Again, this is how in the future standards will

play a role in the connection car environment,

and now for the last lecture on this module it will be on Artificial Intelligence.

Thank you, very much for your attention.
