Safety is the most important
factor while driving a car. Vehicle manufacturers are applying for patents to
prepare for unexpected events such as car accidents and diseases.
Defibrillation system for
self-driving car of Hyundai Motor Company
First, Hyundai Motor Company
applied for a patent regarding a defibrillation system for self-driving
vehicles.
This patent is a system based on
a cardiac arrest detector (Drawing.
10), a cardiac position detector (Drawing. 40), and an X-ray camera
(Drawing. 41). It is a system that once a cardiac arrest is detected from the
driver, it makes the patent to lie on the back by reorganizing the driver seat
to allow defibrillation robot installed around the seat to cut passenger’s
shirt and perform CPR or activate automatic cardiac shock.
It is designed to prevent
unexpected deaths and secondary accidents while driving self-driving vehicles.

<Defibrillation system for
self-driving car>
Hyundai Motor Company applied for
two defibrillation-related patents before filing for a patent regarding the
defibrillation system for self-driving vehicles. The first patent filed in 2017
has a defibrillator system connected to seat belt that measures the heart rate
by leaking electrode material when an abnormality is detected in heart rate or
a cardiac arrest occurs to an occupant. It also includes cardiac shock system
that provides cardiac defibrillation.

<Vehicle AED System and Method
for Operating thereof>
The second patent, filed in 2018,
is a patent for a technology that applies a heart shock through two current
pads placed on the seat belt when the driver is judged to be in cardiac arrest
at the stage of recognizing the driver's condition.
This patent was applied with the
focus on the fact that the average number of repeat passengers in Korea is 1.4,
and the majority of vehicles include only drivers. This emphasizes the fact
that it is difficult to obtain assistance from other passengers in case of
cardiac arrest due to an accident or other reasons.
The difference from the previous
patent is that a camera, speaker, and microphone are used to determine the
driver's condition. The heart rate sensor detects cardiac arrest, and if any
abnormal condition of the driver is captured by in the video by the camera, a
voice message requesting the driver's response will be sent from the speaker.
If there is no vocal response heard back from the driver, the system will automatically
determine that he is in cardiac arrest. This leads to two current pads (Drawing
330 and 340) being discharged to conduct defibrillation.

Vehicle occupant classification
system patent and seatbelt usage detection patent
Tesla has also issued a patent
that can safely protect the vehicle’s occupant.
When taking safety measures to
protect the passenger, it is important to accurately classify passengers.
It is difficult to reliably
detect vehicle occupants and distinguish between children and relatively small
adults.
For more accurate classification
of passengers, Tesla has equipped the vehicle seat with a passenger weight
sensor (Drawing 222) and a passenger presence sensor (Fig. 224, 226). Taking
into account the occupant's posture, position, etc., these sensors communicate
organically and provide occupant classification to the airbag controller
(Drawing 172). This will help reduce the risk of injury by adjusting where the
airbags are activated in the event of a vehicle crash

classification systems and methods>
Tesla has also applied for a
patent that detects improper seat belt use. It is a patent applied with various
sensor fusion technologies that can determine whether the passenger is safely
seated in the seat, whether the seat belt is worn correctly or not, and whether
the passenger is looking ahead.
After verifying that the occupant
has properly fastened the belt, the sensor module (Drawing 402) causes the
information to be received by the controller (Drawing 404) and stored in the
memory (Drawing 406). It may warn you of improper use of seat belts or disallow
vehicle's operation.

When driving a vehicle, sometimes
unexpected situations arise. Even w hen driving safely, accidents can occur. I
hope that more technologies for safety will be applied for patent so that
people can drive in a safer environment.
