Driverless Cars: A Technological Revolution in the Automobile Industry

This presentation discusses the concept of driverless cars, their necessity, and the technologies used in them. It explains how they detect traffic lights and avoid accidents. The presentation also covers the benefits of using driverless cars.

Driver less Cars

Introduction
Driver errors are the basic cause of road
accidents.
Approximately 6% of world’s people die
in road accidents annually.
Factors like entertainment systems, cell
phones, complicated road systems make
road accidents very frequent.
With the help of this technology cars are
able to concentrate for people.

Driver less cars
They can drive without any assistance.
It can drive safely by avoiding obstacles
on road.
It can move or stop according to the
traffic condition.
It accelerates to the appropriate speed
limit.

Necessity of the system
Sensors called mobileye NV
Sensors to control speed of wheels
Rotational-angle sensor
Steering-angle sensor
Operating the mechanics of the vehicle
Planning of motion
Navigation

Detection of traffic lights
A sensor called actinometer helps it to detect
the intensity of radiation
Different colored lights radiate different
radiation intensity
This intensity is detected by the sensor
If the detected color is yellow or red, a
command will be sent to robot to stop the car.

This is an example of
how driverless cars
detect radiations of
various colors and
operate in traffic.
This prevents the car
from facing accidents.

Technologies to be used
Anti-lock brakes
Cruise control
Ability to self park
Control of electronic stability
Guided system that is automated
Self parking

Anti-lock brakes
Brakes may lock up while braking hard,
anti-lock brakes prevent these
Anti lock brakes have
 Speed sensors
Pumps
Valves
Controller

Driverless cars detect
the cars around them
and use their smart
mechanism to avoid
accidents. They
maintain a certain
distance from other
vehicles.

Anti lock braking
system helps the
car to avoid
accidents by
applying brakes
when necessary

Automated cruise control
They use a laser or a radar setup
This allows the car to slow the speed when
in comes near other vehicle
The speed it again normal when the road is
clear
It maintains a safe distance from other
vehicles
Cruise control helps to keep the car a
constant speed

Adaptive Cruise Contro helps the car to
maintain a safe distance from other vehicles
in order to prevent acident.

Automated guided system
This technique uses Free Ranging On
Grid technology(FROG)
FROG vehicles need a computer to
operate
The computer contains a map of an area
where the car travels

Automated guided system helps the car
to chose direction according to the map
and the destination where the owner
desires to travel

Electronic stability control
It improves the stability of the vehicle
It detects and minimizes skids
It applies brakes automatically whenever
needed
Minimizes loss of control
Compares the vehicles real direction with
driver’s desired direction

Navigation
Navigation means the potential to plot the
route of the journey
It also receives radio updates regarding
blockages on roads
It adapts according to the traffic condition
