3. INTRODUCTION
 DRIVERLESS CAR :- A Vehicle that can
drive itself from one point to another
without assistance from a driver , in other
words an autopilot system.

4.  Can steer itself while looking out for
obstacles.
 Can accelerates itself to correct speed
limits.
 Can stop and go itself based on any traffic
conditions.
 Can take the passenger anywhere to go
safely , legally and comfortably

5. HISTORY
 This car is led by : Sebastian Thrun.
 Director of Stanford artificial intelligence
laboratory.
 2005 DARPA grand challenge winner.
 Co. inventor of Google street view.

6. COMPONENTS
 Google map.
 Hardware sensors.
 Artificial intelligence.

7. GOOGLE MAP
 Google map interacts with GPS and acts
like a database.
 Speed limits.
 Upcoming interactions.
 Traffic reports.
 Nearby collisions.
 Directions.

8. HARDWARE SENSORS
• The hardware sensors gives the real time
environmental properties.
• Sensors attempt to create fully observable
environment.
LIDAR.
Video camera.
Position estimator.
Distance sensor.

10. LIDAR
 Heart of the system.
 LIDAR-Light detection and ranging. Is an
optical remote sensing technology that
can measure the distance to the target.
 Scanning distance of 60
meters(~197feet).

11. Video camera
•Detects the upcoming traffic lights.
Distance sensors
•Allow the car to detect the enough distance by
the upcoming vehicles.
Position estimator
•It is also known as wheel encoder.
•Determines vehicle’s location and keeps track of
it’s movements.

12. ARTIFICIAL INTELLIGENCE
 Google maps and the hardware sensors
data are sent to the artificial intelligence.
 It determines
How fast to accelerate.
When to slow down /stop.
When to steer the wheel.
• The main goal is to take the passenger to
it’s desired destination safely and legally.

13. ANTI-LOCK BRAKE SYSTEM
 An anti-lock brake system(ABS) generally
offers improved vehicle control and
decreases stopping distances on dry and
slippery surfaces for many drivers.

15. ELECTRONIC STABILITY CONTROL
 A Computerized technology improves vehicle’s
stability and minimizing skids.
 Automatically applies the brakes.
 Helps to minimize a loss of control.
 ESC compares the driver’s intended direction to
the vehicle actual direction.

16.  Wheel speed sensors
 Steering angle sensors
 Rotational speed sensors

18. ADVANTAGES
 Managing traffic flow to increase road
capacity.
 Reduces the intention of the drivers not to
overtake the other vehicles and also avoids
accidents.
 The current location of vehicle can be
determine using Google Positioning System
(GPS).

19. DISADVANTAGES
 Hackers can change the route map which is
plotted in the system (rare case).
 In case of failure in main sensor and back up
sensors the vehicle can create a chance of
accidents.

20. CONCLUSION
 The driverless car’s technologies improves
vehicles stability helps to minimize the loss of
control.
 Driverless car’s are designed to minimize
accidents by addressing the main causes of
collisions: driving errors , distraction and
drowsiness.
