driverless car...

2. based on automatic control system

3.  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.

4. What an automatic control system is?
What is a driverless vehicle
Types of driverless vehicles based on
different-2- technologies
*drones(signal controlled)
*automated highway system
*driverless cars based on automatic
control system

5. *It is a vehicle that can
drive itself from one point
to another without
Assistance from a driver;
in other words, with an
autopilot system

6. Sensors
Navigation
Motion planning(traffic)
Actuation(operates the mechanics of
vehicle)

7.  Sensors employed in driverless cars are called mobileye N.V
 Mobileye offers a wide
range of driver safety
solutions combining
artificial vision image
processing, multiple
technological applications
and information technology
Wheel speed sensors
Steering-angle sensors
Rotational-speed sensor

8.  A sensor “actinometer “ is used to detect the intensity
of radiation
 Light of different colors will radiate different -2-
intensity of radiation
 Which will be detected by the sensor
 If the detected intensity is of red color or yellow color
The controller will send a command to stop the vehicle
The command will be followed by robot(to convert the
computer command into mechanical input)

9.  Anti-lock brakes(ABS)
 Electronic stability control (ESC)
 Cruise control
 Self Parking
 Automated Guided Vehicle Systems

10.  While braking hard without anti-lock brakes, the wheels
can lock up, sending the car into an out-of-control skid.
and the driver has to pump the brake pedal to keep the
wheels from locking up
 With anti-lock brakes, the system does the pumping for
the driver - and does it better than the driver. The system
can read the wheels and knows when they are about to
lock and react faster

12.  Autonomous cruise control is an optional cruise
control system appearing on some more upscale vehicles.
These systems use either a radar or laser setup allowing
the vehicle to slow when approaching another vehicle
and accelerate again to the preset speed when traffic
allows
 It also maintain a set distance between it and the car in front
of it
 Cruise control keeps the car at a constant speed

14. Automated Guided Vehicle Systems
 Uses FROG (Free
Ranging On Grid)
technology
 FROG vehicles are
equipped with a
computer that
contains a map of
the area

15. The ability to plot the rout from
where the vehicle is to where the
user wants to be has been available
for several years
 the more sophisticated system
also receives radio updates on road
blockages, and adapt accordingly

16.  is a term used
in robotics for the process
of detailing a task into
discrete motions.
 It should execute this task
while avoiding objects like
other cars.

17.  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.

19.  It is a prize competition
for driverless vehicles,
funded by the(Defense
Advanced Research
Projects Agency), the
most prominent research
organization of
the United
States Department of
Defense.

20.  Saving lives on the
battlefield
(by sending unmanned
vehicles).
 Minimize the probability
of accidents in cities.

21.  The course involved a 96
km to be completed in less
than 6 hours
 Rules included obeying
all traffic regulations while
negotiating with other
traffic and obstacles and
merging into traffic.

22.  managing traffic flow to increase road capacity.
 relieving vehicle occupants from driving and
navigating chores, so 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 determined using
global positioning system(G.P.S)

23.  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
