2. Introduction
History
Vehicular hardware
Working
Comparison
Potential advantages
Potential obstacles
Official prediction
conclusion

3. Vehicular automation involves the use of
Mechatronics
Artificial Intelligence
to assist a vehicle's operator.
These features and the vehicles employing them may be
labeled as intelligent or smart

4.  An autonomous car is also called
as self driving car, driverless car or
robotic car, an autonomous vehicle
capable of fulfilling the human
transportation capabilities of a
traditional car.
 As an autonomous vehicle, it is
capable of sensing its environment
and navigating without human
input.

5. Driver less car is a project by Google that
involves
the developing technology for autonomous
car
The software powering car is called
“Google chauffeur”
This project is being led by Google engineer
and team
This team has 15 engineers

6. RADAR
Video camera
LIDAR
GPS
Processors
Wheel Speed Sensors

8.  Traditional RADAR sensors are used to detect
dangerous objects in the vehicle’s path that are
more than 100 meters away.
 Accident-Prevention systems trigger alerts when
they detect something in a blind car’s blind spot.
 The radar chirps between 10 and 11 GHz over a
5 millisecond period, transmitting the radar signal
from a centrally located antenna cone.
 Two receive cones, separated by approximately
14 inches, receive the reflected radar energy.

9. A video camera installed at the top
of the front glass near the rear-
view mirror.
These cameras are used to detect
the traffic lights , pedestrians,
animals etc.
It is also used to identify road
markings and traffic signals.

10.  The Light Detection And Ranging (LIDAR) which is mounted on the roof
of the vehicle is the most important device in the Autonomous vehicles.
 The LIDAR consists of an emitter, mirror and receiver.
 The emitter sends out a LASER beam that bounces off a mirror that is
rotating along with the cylindrical housing at 10 revolutions per minute.
 After bouncing off objects, the LASER beam returns to the mirror and is
bounced back towards the receiver, where it can be interpreted into
data.
 The vehicle can then generate a map of its surroundings and use the
map to avoid objects.

12. The global positioning system(GPS) is a
space based satellite navigation system that
provides location and the time information.
But the data alone with the GPS system is
less accurate so this data is combined with
the outputs from the IMU(inertial
measurement unit)
IMU is an electronic device which measures
and gives the information about vehicles
velocity

13. Some 7 dual-core 2.13 GHz processors and 2Gb of RAM
are needed to make sense of the data collected by the
car’s instruments.

14.  Wheel Speed Sensors
measure the road-wheel
speed and direction of
rotation.
 These sensors provide input
to a number of different
automotive systems including
the anti-lock brake system and
electronic stability control.

15.  The signal from the sensors are used by the Electronic
Control Unit for decision making using a software code.
 Based on the information from the sensors, the Electronic
Control Unit gives signal to the actuators, which in turn
control the vehicle.
 Also, real time information of the surroundings is output to
the user interface located inside the vehicle.

16. Google Maps and the hardware sensors
data are sent to the AI.
AI then determines:
how fast to accelerate
when to slow down/stop
when to steer the wheel
Goal of AI
The agent's goal is to take the passenger to
its desired destination safely and legally.

19.  Minimize accidents rates in cities
 The system will allow the commuters to do other things
while travelling such as reading or sleeping.
 Increased roadway capacity and reduced traffic congestion
 Relief of vehicle occupants from driving and navigation
chores.
 Higher speed limit for autonomous cars.
 Alleviation of parking scarcity.
 Reduction of space required for vehicle parking.
 Reduction in the need for traffic police and vehicle
insurance.
 Smoother ride.

20.  As of August 28,2014 the latest prototype cannot “Handle
heavy rain and snow covered roads”.
 Chris Urmson of Google said That the LIDAR technology
cannot spot a police officer signaling car to stop
 Vehicles are unable to differentiate between crumpled up paper
and a rock
Loss of driver-related jobs
Temporary construction zones which are not posted to any
maps or data bases.
According to Google, projects having these issues fixed by 2020.

21. Toyota Prius modified to operate as a Google driverless
car

22.  By 2014, Israeli company Mobileye expects to release semi-
autonomous car technology.
 By 2015, Audi plans to market vehicles that can autonomously steer,
accelerate and brake at lower speeds, such as in traffic jams.
 By 2016, Mobileye expects to release fully autonomous car technology.
 By 2017, Google expects to release their autonomous car technology.
 By 2020, Volvo envisages having cars in which passengers would be
immune from injuries.
 By 2020, Mercedes-Benz, Audi, Nissan and BMW all expect to sell
autonomous cars.

23. • Many carmakers developing prototype vehicles that are capable of driving
autonomously in certain situation.

24. Although legal issues connected to driverless cars have
raised many questions, as driverless car is still in research,
hope we can see driverless car running on roads soon
which would overcome all these obstacles and issues in
the future, let’s wait and see
Could be ready for market as little a 4-5 years
