IoT Connected Car Insights from Patents
Patents are a good information resource for obtaining IoT (Internet of Things) technology development status.
Followings illustrate some examples of patents that provide current status of the IoT connected car technology
development: safety/collision avoidance, traffic information for smart driving, connected car security, infotainment
and self-driving car monitoring.
Safety/Collision Avoidance
US 20150146605 (V2V SAFETY SYSTEM USING CONSENSUS; Zetta Research and Development) illustrates a
system for safety and anti-collision exploiting the vehicle-to-vehicle (V2V) communication system. A V2V
communication transponder in a vehicle broadcasts in a repeating, fixed-time frame (e.g. 10 times per second) a
series of V2V safety messages comprising the vehicle's position, heading and speed. The transponder in a specific
vehicle determines a subset of vehicles within communication range, the "consensus set" in which the transponder
computes, for each vehicle in the consensus set, the transponder relative position between vehicles using iterative
algorithm. Vehicle location may be determined by a combination of GPS, inertial guidance, and other sources.

US20150149059 (AUTOMATIC SPEED CONTROLLABLE VEHICLE AND METHOD FOR CONTROLLING
SPEED THEREOF; Hyundai Mobis) illustrates an automatic speed controllable vehicle exploiting vehicle-to-
infrastructure (V2I) communication system. The vehicle collects vehicle information and transmitted collected
vehicle information to an road side equipment (RSE). The RSE receives vehicle information from each vehicle
within a management section and transmits again, to each vehicle, information required for each vehicle to adjust a
speed. The vehicle receiving information required to adjust the speed may adjust the speed of the vehicle based on
the received information and may display a warning notification for a driver.

US 20150054659 (COOPERATIVE VEHICLE COLLISION WARNING SYSTEM; Fujitsu) illustrates a
vehicular communication systems enable vehicles to wirelessly communicate with each other to exchange traffic
information and generate safety warnings depending on the traffic information exploiting V2X (V2V and V2I)
communication system. The vehicular communication system includes a receiver and a transmitter. The receiver
may be configured to receive a message relating to traffic conditions along a thoroughfare from a communication
node. The transmitter may be communicatively coupled to the receiver and may be configured to rebroadcast the
message within a predetermined amount of time after receiving the message. The traffic information
communication system may be implemented in a vehicle traveling along the thoroughfare.
Traffic Information for Smart Driving

US20150170522 (METHOD FOR TRANSMITTING TRAFFIC INFORMATION USING VEHICLE TO
VEHICLE COMMUNICATION; Hyundai Motor Company) illustrates a method for transmitting traffic
information using V2V communication system. A first vehicle communication terminal detects an occurrence
event and transmits the traffic information message through V2V communication. A second vehicle
communication terminal, which drives in an opposite direction as compared to the first vehicle terminal, receives
and analyzes the traffic information. The second vehicle communication terminal transmits the traffic information
message to a third vehicle terminal located behind the first vehicle terminal depending on an analysis result of the
traffic information message by the second vehicle terminal and outputting an alert based on the event occurrence
information of the traffic information message transmitted from the second vehicle terminal to the third vehicle
terminal.

US20140063064 (INFORMATION PROVIDING METHOD AND INFORMATION PROVIDING VEHICLE
THEREFOR: Samsung Electronics) illustrates a method of providing information about a predetermined external
vehicle on a transparent display of an information providing vehicle. The method includes steps of acquiring status
information of the external vehicle; determining a display mode for displaying an object corresponding to the
external vehicle based on the acquired status information; and displaying the object corresponding to the external
vehicle on the transparent display in the determined display mode. The display mode may include an augmented
reality mode displaying an image obtained by overlaying a virtual image on an actual image of the external vehicle
that is observed through the transparent display, and a map mode displaying the object corresponding to the
external vehicle after mapping the object to a map.

Connected Car Security
US20150020152 (SECURITY SYSTEM AND METHOD FOR PROTECTING A VEHICLE ELECTRONIC
SYSTEM; ARILOU INFORMATION SECURITY TECHNOLOGIES) illustrates a security system for protecting
a vehicle electronic system by selectively intervening in the communications path in order to prevent the arrival of
malicious messages at Electronic Control Units (ECUs). The security system includes a filter which prevents
illegal messages sent by any system or device communicating over a vehicle communications bus from reaching
their destination. The filter may, at its discretion according to preconfigured rules, send messages as is, block
messages, change the content of the messages, request authentication or limit the rate such messages can be
delivered, by buffering the messages and sending them only in preconfigured intervals.

US 20150150124 (Cloud-assisted threat defense for connected vehicles; Cisco) illustrates a system for cloud-
assisted threat defense for connected vehicles. A vehicle includes an on-board computer system for operating
and/or controlling various systems on the vehicle. The on-board computer system operates in connection with or
includes an on-board threat defense module or a cloud-based security component for detecting and protecting
against malware attacks and other security threats to the vehicle.

10
Infotainment
US20130083061 (FRONT- AND REAR- SEAT AUGMENTED REALITY VEHICLE GAME SYSTEM TO
ENTERTAIN & EDUCATE PASSENGERS; GM) illustrates an augmented virtual reality game for a vehicle. A
real-time video image during operation of a vehicle from a camera mounted on the vehicle merges with virtual
images to provide an augmented reality image. The augmented reality image is then transmitted to a display of a
gaming device during the operation of the vehicle.

11
US20130086164 (Automobile social networking; Broadcom) illustrates a technique to identify vehicles proximal
in distance to a user's vehicle travelling on a road. The user's vehicle transmit wirelessly to the vehicles an inquiry
to attempt to communicate with one of the vehicles and when a response is received in the affirmative from an
intended target vehicle. Then, the use adds the intended target vehicle to a social networking group and establishes
a wireless communication link between the user's vehicle and the responding target vehicle to conduct vehicle-to-
vehicle wireless communication between the user and an occupant in the responding target vehicle. Subsequently,
other vehicles may be added to the social networking group to provide a platform for conducting conversations and
information exchange among the social networking group.

12
Self-Driving Car Monitoring
US 20150158499 (VEHICLE MONITORING SYSTEM: Magna Electronics) illustrates an automated vehicle
monitoring system that includes a central processor operable to receive vehicle inputs from multiple vehicles. The
vehicle inputs are indicative of driving conditions of the vehicles. The central processor is operable to receive, for
each vehicle of the multiple vehicles, an environment input indicative of the environment at that vehicle.
Responsive to the vehicle inputs and the environment inputs, the central processor determines if one or more of the
multiple vehicles is at or approaching a hazardous condition. Responsive to a determination that one or more of the
multiple vehicles is a threatened vehicle at a potentially hazardous condition, the central monitoring system at least
one of (i) actuates an alert of the threatened vehicle to alert a driver of the threatened vehicle of the determined
hazardous condition and (ii) controls a vehicle system of the threatened vehicle to mitigate the determined
hazardous condition.
