3. Introduction
What do you mean by Autonomous Car?
A word autonomous is derived from a Greek roots.
Autonomous = autos + nomos
(SELF) (GOVERN)
So, Autonomous car is a vehicle that can drive itself from
one point to another without assistance from a driver; in
other words, with an autopilot system.
4. Introduction
What is the need of this type of car?
Driver error is the most common cause of traffic
accidents.
India contributes 6 % of the world's road accident deaths.
Cell phones in-car ,entertainment systems, more traffic
and more complicated road systems making it more
frequent.
By this improving technology our car will do the
concentrating for us.
5. History
Experiments have been conducted on automating
cars since the 1920s.
The first self-sufficient and truly autonomous cars
appeared in the 1980s,
with Carnegie Mellon University’s project in 1984
and
Mercedes-Benz & Bundeswehr University Project in 1987.
Since then numerous major companies have
developed working prototype of autonomous car.
6. Working
Driver sets a destination and car’s software
calculates a route and starts the car on its way.
A rotating, roof-mounted LIDAR (Light Detection
and Ranging) sensor monitors a 60-meter range
around the car and creates a dynamic 3-D map of
the car’s current environment.
A sensor on the left rear wheel monitors sideways
movement to detect the car’s position relative to
the 3-D map.
7. Working
Radar systems in the front and rear bumpers
calculate distances to obstacles.
Artificial intelligence software in the car is
connected to all the sensors and has input from
Google Street View and video cameras.
The AI simulates human perceptual and decision-
making processes and controls driving systems
such as steering and brakes.
8. Working
The car’s software consults Google Maps for
advance notice of things like landmarks and traffic
signs and lights.
An override function is available to allow a human
to take control of the vehicle.
10. Components
The systems used in the car are:
LIDAR (Light Detection And Ranging)
Radar System
Ultrasonic Sensors
Video Cameras
GPS (Global Positioning System)
Inertial Measurement Unit
CPU or computer
12. Components
LIDAR:
It is a remote sensing technology which measures
distance by illuminating a target with a light beam and
analyze the reflected light.
It uses laser, ultra violet, visible light or infrared light to
image objects.
RADAR:
The radar system are used for detecting oncoming
vehicles , their speed , other obstacles , for self parking ,
blind spot detection etc.
The Radar systems are installed on the front and rear
bumper of the vehicle.
13. Components
Radar detects the surrounding environment and the
central computer combines this result with that of the
LIDAR system.
ULTRASONIC SENSORS:
These are used for Blind Spot detection as well as to
detect nearby objects or measure the position of other
vehicles during parking.
These sensors are mounted on the left rear wheel of a
vehicle.
VIDEO CAMERAS:
Video cameras are installed at the top of the front glass,
near the rear view mirror.
14. Components
These are used to detect the traffic lights, traffic signs,
pedestrians etc. They also detect different road signs like
“ STOP” signs, zebra crossings, sign Boards etc.
GPS:
GPS uses satellites to gather information about the
current position of the vehicle. By using the GPS a map of
the area is loaded into the central computer.
INERTIAL MEASUREMENT UNIT:
Data from GPS alone is less accurate . So , this data is
combined with outputs from the IMU.
IMU uses a combination of accelerometers, gyroscopes
and magnetometers.
15. Components
IMU is an electronic device which measures and gives
information about the vehicle’s velocity, orientation,
gravitational forces etc.
IMU helps GPS system to work when signals are
unavailable such as in tunnels, bad weather conditions
and when electromagnetic interference is present.
CPU:
All the data obtained from each and every sensor systems
is fed to the central computer.
The central computer is a very powerful processing unit
mounted on the inside of the vehicle.
16. Advantages
Reduction in car accidents
Optimal speed
Increase in productivity
Efficient use of highways
Fuel Economy
Maximum utilization of parking space
Reduction in the need for traffic police and vehicle
insurance
Reduction in car theft, due to the vehicle's self-
awareness
17. Disadvantages
Chances of hacking
Failure of sensor leads to accident
Loss of privacy
Fewer job
Can be used for terrorism
Competition for radio spectrum
18. Present Scenario
In June 2011, the Nevada Legislature passed a law
to authorize the use of autonomous cars.
In 2013, the government of the United
Kingdom permitted the testing of autonomous
cars on public roads.
In 2014 the Government of France announced
that testing of autonomous cars on public roads
would be allowed in 2015. 2000 km of road would
be opened through the national territory for
testing.
