Google Driverless Car
4. INTRODUCTION:
The Google Driverless Car is like any car,
but:
It can steer itself while looking out for
obstacles.
It can stop and go itself based on any traffic
condition.
It is a combination of different technologies
developed by Google
That will allow a car to drive itself even on
the highway

5. Contd:
The project is currently being
led by: Sebastian Thrun
Director of the Stanford
Artificial Intelligence
Laboratory
2005 DARPA Grand
Challenge Winner
Co-inventor of Google Street

Google Driverless Car
6. Contd:
Uses Google map, sensors, artificial intelligence
Lidar produced detailed map of the environment
Car uses white stripes on road to know lanes
360 degree motion sensor and cameras to sense
Control of the car still exist
Sensors pushing data into main computer to
process information

7. COMPONENTS:
Integrates Google Maps with various hardware
sensors and artificial intelligence software
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

9. HARDWARE SENSORS:
The hardware sensors gives real time
environmental properties.
Environment is dynamic so need real time
results.
Sensors attempt to create fully observable
environment.

10. HARDWARE SENSORS:
LIDAR
VIDEO CAMERA
POSITION ESTIMATOR
DISTANCE SENSOR

12. LIDAR
“Heart of our system“
LIDAR is an optical remote sensing technology
Measure the distance to, or other properties of a
target
It often using pulses from a laser.
Scanning distance of 60 meters (~197 feet)

13. VIDEO CAMERA
Detects upcoming traffic light.
Recognizing moving obstacles like pedestrians and
vehicles
DISTANCE SENSOR
Allow the car to "see" far enough to detect nearby or
upcoming cars or obstacles
It also contain radar

14. Contd:
object returns a tiny part of the wave’s energy to a
dish
Radar system has a transmitter that emits radio
waves called radar signal
Doppler effect

15. POSITION ESTIMATOR(Wheel
Encoder)
Determines vehicle's location and keeps track of
its movements.
GPS is a space based satellite navigation system
that provide location and time information
It is maintained by the US government
It freely accessible by anyone with a GPS receiver
12/23/2022 Google Driverless Car 15
16. ARTIFICIAL INTELLIGENCE:
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

17. WORKING
The motors are first have to be installed
Apply pressure to both accelerator, brake pedals
and turn the wheels
Motor receiving instructions from computer
Lidar used to detect objects and distance
video cameras detect traffic light
Control of the car would still exist

18. LET'S SEE IT IN ACTION!
A look from the inside... A look from the outside...

Google Driverless Car
19. ADVANTAGES
Improved fuel efficiency
It will be of great help to people who are
physically challenged
Higher speed limit for autonomous cars
Reduction of space required for vehicle parking.
Fewer traffic collision
12/23/2022 Google Driverless Car 19
20. DISADVANTAGES
So many taxi drivers can lose their jobs
It steals driving pleasure from drivers who love it
It requires that the road are in good condition and
follows a strict traffic system
13/2/2013 Google Driverless Car 20
21. CONCLUSION:
Very useful .
Avoid accidents on the road
Reduce the traffic time at traffic signal
So many taxi drivers can loss their job
Vehicles could be ready for market in as
little as three to five years.
