The document discusses Google's driverless car project, including its history starting in 2009, the key components like sensors and artificial intelligence that allow it to drive autonomously, and some of the technologies that enable functions like cruise control, parking assistance and collision avoidance. It provides details on how the car uses sensors and AI to navigate roads safely and get passengers to their destinations, as well as potential advantages like increased road capacity and safety and disadvantages around security issues.

3. The Google Driverless Car is like any car, but:
 It can steer itself while looking out for obstacles.
It can accelerate itself to the correct speed limit.
It can stop and go itself based on any traffic
condition.
It can take its passengers anywhere it wants to
go safely, legally, and comfortably.
Introduction

4.  The project is currently being
led by: Sebastian Thrun
 Director of the Stanford
Artificial Intelligence
Laboratory
 Co-inventor of Google Street
View
History

5.  Google Maps
Provides the car with road information
 Hardware Sensors
Provides the car with real time environment
conditions
 Artificial Intelligence
Provides the car with real time decisions
Components

6.  Google Maps interacts with
GPS and acts like a
database.
 Speed Limits.
 Upcoming intersections.
 Traffic Report.
 Nearby collisions.
 Directions.
Google Maps

7. Sensors attempt to create fully observable
environment
The hardware sensors gives real time
environmental properties.
Environment is dynamic so need real time results.
results.
Hardware Sensors

8. 1. LIDAR
2. VIDEO CAMERA
3. POSITION ESTIMATOR
4. DISTANCE SENSOR
Hardware Sensors

10. “Heart of the system“
LIDAR stands for Light Detection And
Ranging.
It is an optical remote sensing technology.
It can measure the distance to, or other
properties of a target by illuminating the
target with light.
Scanning distance of 60 meters (~197 feet)
Lidar

11. Video Camera
Detects upcoming traffic light.
Distance Sensor
Allow the car to "see" far enough to detect nearby or
upcoming cars or obstacles
Position Estimator
Determines vehicle's location and keeps track of its
movements.

12. 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
Artificial Intelligence

13. Anti-lock brakes(ABS)
Electronic stability control (ESC)
Cruise control
Lane Departure Warning System
Self Parking
Automated Guided Vehicle Systems
Technologies Used

14. An ABS generally offers improved vehicle control and decreases
stopping distances on dry and slippery surfaces for many drivers.
Anti-lock brakes System (ABS)

15. A computerized technology
improves vehicle's stability
by detecting and minimizing
skids.
Automatically applies the
brakes.
Helps to minimize a loss of
control.
ESC compares the driver's
intended direction to the
vehicle's actual direction
Electronic Stability Control (ESC)

16. Cont…..

17. Cruise control keeps the car at a constant speed by taking over
the throttle of the car.
It also maintain a set distance between it and the car in front of
it
Cruise control

18. A mechanism designed to
warn a driver when the
vehicle begins to move out
of its lane.
Designed to minimize
accidents by addressing the
main causes of collisions:
driving error, distraction
and drowsiness.
Lane Departure Warning System

19. System uses sensors all around the car to guide it into a
parallel parking space.
Lexus LS 460 L with Advance Parking Guidance
System.
The driver has to find a parking space,Position the car
next to it, and use the in-cabin navigation screen to tell
the car where it should go.
The parking space needs to be 6 feet (1.8 meters) longer
than the car
Self-parking

21. As automotive technology matures, more and more
functions of the underlying engine, gearbox etc. are no
longer directly controlled by the driver by mechanical
means.
It is controlled via a computer, which receives instructions
from the driver as inputs and delivers the desired effect by
means of electronic throttle control.
Therefore, the technology for a computer to control all
aspects of a vehicle is well understood.
Automated Guided Vehicle System

22. Let’s See it in Action !
A look from the inside... A look from the outside...

23. As of 2014:
 Nevada
o 1st state to allow driverless vehicles can be legally
operated on public roads
 6 Google Driverless Cars
o 5 Toyota Prius
o 1 Audi TT
 Total miles
In April 2014, the team announced that their vehicles have
now logged nearly 700,000 autonomous miles (1.1 million
km
 New Prototype
On May 28, 2014, Google presented a new prototype of their
driverless car that had neither a steering wheel nor pedals.
As on Today !

24. Managing traffic flow to increase road capacity.
Relieving vehicle occupants from driving allowing them to
concentrate on other tasks or to rest during their journeys.
To avoid accidents .
Increasing roadway capacity by reducing the distances
between cars.
The current location of vehicle can be determine using
global positioning system (G.P.S) .
Advantages

25. If the vehicle is using internet which is have less
security then From the hackers point of view in some
cases the vehicle can be switched off on the road(in rare
cases)
Hackers can change the rout which is plotted in the
system(in rare cases)
In case of failure of main sensor and backup sensors the
vehicle can create a chance of accident
Disadvantages

26. The driver less car’s technologies improves vehicle's
stability helps to minimize loss of control.
Driver less cars are designed to minimize accidents by
addressing the main causes of collisions: driving error,
distraction and drowsiness.
