Identification/definition of the Connected Car (How do I recognize it?)
It was rumored that at a computer expo many years ago, Bill Gates made a joke that "If GM had kept up with
technology like the computer industry has, we would all be driving $25.00 cars that got 1,000 miles to the
gallon." While it is debatable whether Bill Gates actually made this remark, what is not debatable is the inclusion
of high technology features and functions that are constantly being introduced to the automotive industry.
With the earliest introduction of a simple controller in Volkswagen cars equipped with electronic fuel injection
in the late ‘60s, computers have taken on more responsibilities as the years have passed. While not necessarily
required to implement fuel injection, with the advent of more federally mandated emissions controls required
in the ’70s and ‘80s, computers became necessary to make cars more fuel efficient and cleaner. In today’s
automobiles computers are connected to everything from the Automatic transmission to Zone controlled air
conditioners and people are expecting more features in their cars that allow them instant status updates for
many systems in their automobiles. In 1996, GM launched *OnStar which then offered services to allow for
automatic emergency
response should the car be
involved in an accident and
some simple concierge
services similar to phone
operator services.
Connected cars can be simply
defined as automobiles that
allow for connectivity to
services beyond what is
inherently a part of the car
itself. This includes a range of services as simple as connectivity to a cell phone that allows for information to
be exchanged between the phone and the car all the way to a fully autonomous vehicle that gathers information

from its environment via on-board sensors, Vehicle-to-Vehicle (V2V) communications or Vehicle-to-
Infrastructure (V2I) communications.
Explanation and profile of the Connected Cars
At the core of the connected car, is a computer controller that listens and talks to the various sensors and
controllers throughout the car. The sensors allow the computers to react to external/internal stimuli and are
the human analogue of the following:
1. Touch – to feel the slightest vibration, pressure or temperature in many systems of the car
2. Hearing – to hear voice commands inside the cabin
3. Smell/Taste – to examine the exhaust and gas vapors present in different systems
4. Sight – To view the cars surroundings for lane markings, other vehicles or parking spots
The connected car interacts with the external environment though one of three ways
1. V2V – Also known as Car-to-Car (C2C), V2V is the communications
mechanism through which vehicles are aware of other vehicles within
their immediate vicinity. The V2V communication standards are still a work in progress between key
players and the governing bodies like the US DOT, NHTSA, CEN and ETSI. These standards are a
vital requirement to ensuring that all OEM and aftermarket system manufacturers allow for
communicated information to be received timely, reliably and in a standard format over a common
channel (currently a 75MHz bandwidth spectrum in the 5.85 – 5.925 GHz frequency band).
2. V2I – also known as Car-to-Infrastructure (C2I),
V2I is the mechanism through which cars will talk
to the infrastructure to obtain information about
current traffic loading and potential emergency
conditions so the driver and/or vehicle can
respond appropriately. Currently slated to
operate in the 5.9 GHz spectrum, the primary
goal of V2I is to minimize traffic accidents and
the injuries associated with the accidents. An
additional targeted benefit includes
environmental gains such as better fuel efficiency
by helping traffic flow more consistently. One of
the ultimate goals for the V2I systems in to
reduce potential crash scenarios by an additional 12% over a V2V system.

3. V2X – when vehicles are able to communicate to both Infrastructure and other vehicles. In this case,
As implied in the V2I implementation, there is also a requirement that local and federal governments will have
to start adding the required smart traffic management systems such as traffic lights, roadway departure warning
systems, lane management systems to allow for emergency vehicle passage.
Figure 3 - V2X encompasses communications between vehicles and Infrastructure
Recent applications (initial target domains)
The initial application domain available for connected cars was initially
focused on simple navigation. Before the advent of GPS satellites, GM
was experimenting with their Driver Aid in Routing (DAIR) project
which utilized encoded magnets imbedded in the road. These magnets
were read by the in-car DAIR system which used indicator lights to
indicate direction. Today, connected cars provide for a growing revenue
stream and connected cars perform some of the following more popular applications
1. Communications and Concierge services are available on many vehicles. These paid services allow
a driver to interact with the system operator to get directions push down to their navigation system,
make reservations, schedule maintenance
appointments and a host of other services while
keeping their eyes on the road. Additionally,
emergency calls can be placed automatically when
the car senses it has been involved in a collision to
improve emergency response times.
2. Engine diagnostics through the use of a phone
application or a call to the car manufacturer, a
RICHARD GALINAITIS 5

connected car owner can get the current status of critical automobile systems and schedule a
maintenance appointment as needed.
3. Autonomous and Semi-Autonomous driving applications are available in several vehicles today.
From applications that find and automatically park the car to adaptive cruise control systems that slow
down or stop as needed based on traffic ahead of the vehicles. Some cruise control systems even
utilized lane changing sensors to keep the automobile in the current lane of travel, thereby requiring
minimal driver interventions when travelling long stretches of highway.
4. Smart Navigation systems that receive traffic and accident alerts over the air and are able to
recommend alternative routes to avoid traffic congestion.
5. Security and Safety are also major application uses. For example, when a connected car is stolen, the
owner only need to contact their service provider in conjunction with police to get the location of the
stolen vehicle. Additionally, if the connected car is involved in a police chase, the car can be safely
disabled by a remote signal.

Identification of major players/users
A number of different industries have the opportunity to work in the connected car domain. Among them are
the obvious automobile and third party infotainment/navigation manufactures. But there are also service
industries that can also take advantage of what connected cars have to offer.
Automobile Manufacturers are being asked to provide more and more features in automobiles. What once
started with simple on-board diagnostic port has now evolved to cars that locate a parking spot and park

themselves. Many car manufactures will begin offering semi-autonomous vehicles that will make long boring
drives safer as the cruise control systems will include systems that maintain the car in the current lane and slow
down or stop as needed. While these systems will take some of the burden off
the driver, they will still alarm the driver with subtle alarms if the car senses the
driver is falling asleep.
Telecommunication companies have played a roll in connected cars since the
introduction of *OnStar in 1996. Many making deals with the various
automobile manufacturers to be the telecommunications operator that
supports the on-board communications suite, whether it is simply voice or
high-speed data. As shown in the chart below, Mobile Network Operators are
positioned very well if the forecasts prove to be accurate. However, connected cars will require robust
broadband networks and reliable coverage.

As cars become more connected, insurance companies may be well suited
to take advantage of the data that can be collected via mobile cars. By
offering discounts to drivers that are willing to supply them with data
collected regarding driving habits, insurance companies can better assess the
risk of insuring any given driver. The insurance companies can then offer
better rates who have better driving habits and charge higher rates to those
who either exhibit bad driving habits or are not willing to share their driving habit data.

Assessment of limitations and potential
Along with the many benefits that are made possible by connected cars, there are some very real concerns when
it comes to connected cars and the data that they collect. First and foremost on the minds of many consumers
is the security aspect. As more and more systems are connected in the automobile along with the additional
controls that are added for convenience like self-parking. People have fears, whether rational or not, that
someone with malicious intentions could take over your car while you are driving and do serious harm.
As cars get more and more complex, they may require over-the-air updates to ensure the automobile has the
latest and greatest software. One such vehicle, the Tesla, receives periodic software updates to address bugs
with the car or to achieve better battery performance.
These updates are only performed once the
automobile owner has acknowledged that they want
the update and they can even schedule the update to
take place in the late night hours when the car will be
sitting in the garage for several hours. To address the
security concern, Elon Musk has been a participant
at computer security conferences like DEF CON.
Making a presence with the full intention of hiring
security experts, he has also reached out to hackers
by presenting the challenge of trying to hack into the car and offering prizes to those who are successful. As
the connected car industry is still in its infancy, there are many security experts who strongly believe that the
industry is far from being prepared for the potential security threats that exist.
One additional limitation that also exists in the connected car market is also a great potential for product
developers. The fact that there are over 250 million registered cars in the US, based in 2012 data, presents a
serious problem to the reality of a fully connected car network. In order for some of the expected hoped for
safety improvements to be realized, it has been estimated that connected vehicle penetration must be as high
as 95%. Considering that automobile purchases are the second largest investment for most Americans, we tend
to hold on to our automobiles for upwards of seven years. With a technology that advances as fast as connected
cars, this means that many systems can become outdated in a matter of two or three years. This is where the
market presents an incredible opportunity for third party vendors that are able to create in-dash head units or
standalone dash mounted units. This market space can easily be fulfilled by manufactures in the automobile
infotainment industry or even by telecommunications operators like AT&T, Verizon or Sprint working
independently or in conjunction with Telecommunications vendors like Alcatel-Lucent, Ericsson, Huawei, etc.

How should one decide when to adopt and how to employ the technology?
Aside from the consumer market, the implications for connected automobiles are just as important for
commercial trucking. Imagine if truckers are better informed about road hazards ahead of them so they can
make better decisions about the
routes that they choose to take.
With better information about the
route conditions they can better
plan when they drive and when to
take breaks. While it is not the
number one cause of commercial
truck accidents, fatigue does play a
part in accidents.
For many, the choice will be
included in the new cars that are
bought. For other with older cars,
they will have to make the decision
of when to adopt the technology.
Decision factors driving connected car adoption:
1. Has connected car adoption been federally mandated?
2. How widely adopted are connected car systems?
3. Have the communications standards been finalized?
4. How old is the car and what kind of diagnostic port, if it has one at all?
5. What types of services are desired?
6. Does my mobile operator offer a package that satisfies my needs?

Future development and expectations
The natural evolution for connected cars is toward truly autonomous vehicles. As once exhibited in science
fiction movies like iRobot and Minority Report, autonomous vehicles will allow for safer travel along city roads
and highways at higher speeds. There is a definite
potential for more efficient travel along the
congested roads with fewer queuing issues due to
the different rates of speed that driver invariably
travel.
One would suspect that the biggest hurdle for
autonomous vehicles would be in trusting them.
However, customer surveys suggest that the
hurdle is not that large. When presented with the
opportunity to save money on insurance, an
overwhelming majority were
willing to let the car drive itself.
Additionally, the general car
consumers in emerging markets
are very willing to trust
automated vehicles.
Much like the application
development community
embraced the smart phone
market, the potential for
application development for
connected cars is large. For this to happen, the manufacturers of connected cars and aftermarket products need
to provide for an open source strategy. Ford, along with many of the large automobile currently support open
source and are members of the open automotive alliance. To continue to attract developers and increase the
number of connected car applications, GM has made development kits available to the public.
Finally, with the continued growth of connected cars, there will always be a concern for security and potential
viruses. This may bring about new divisions in software security companies such as Symantec or McAfee.

Conclusion
Connected cars are a reality today to a certain degree. Todays’ connected car can be said to be simple V2I
implementations since cars rely on communications with the outside world to obtain information, whether it is
a navigation or a traffic update. As the standards are agreed upon by the member organizations, V2V, V2I and
V2X will continue to include more applications. Since connected cars can be a significant source of revenue
for application developers and mobile operators, it is in their best interests to make sure the standards are
robust enough to future proof the technologies.
Connected cars natural evolutionary march is toward autonomous vehicles. We must take these steps very
carefully so public trust in connected cars can be maintained as autonomous vehicles become more widely
adopted. Given that a primary goal of connected cars is to reduce injuries that are directly related to preventable
accidents, due diligence is imperative to ensure that the communications systems are as secure as possible so
the systems cannot easily be the target of an individual’s angst.
