61 person dies every 6 minutes 10 are
injured in the same frame
Indias share of global car accidents is
10%
6% of the worlds road accident deaths
happen in India.

8. BLUETOOTH
Bluetooth can communicate
with 8 other devices
simultaneously
Hence we can check the speed
of 8 cars simultaneously
Range of communication is up to
100 meters of each other
100 mts
9. Equipment
The group of 8 devices is known as
PICONET.
PICONET is a collection of master
and slaves .
The frequency of 2.4GHz is
shared among all the devices in the
piconet.
10. Equipment
Master is a device
which controls all
the devices around
it.
Slave is a device
which is being
controlled by a
master.
• Here A,B are masters and S1 to S6 are the
slaves.
11. >100 mts.
• If the distance between two
vehicle is within the 100m the
Bluetooth devices get enabled.
<=100 mts.
12. •If the distance come closer
within 10m the automatic
braking system takes the
control.
<10 mts.
14. • Short distance, low power radio
operating in the unlicensed
spectrum of 2.4 GHz and using a
nominal antenna power of 20
dBm.
• At the 20 dB the range is 100
meters, meaning equipment must
be Within 100 meters to each
other (about 328 feet) to
communicate using the
Bluetooth standard.
• With the help of this technology
we can send data to the eight
devices.
15. Automatic braking pump and valves
A computer constantly monitors the distance
between each of these cars
When its senses that the car is getting too
close it moves the hydraulic valves to increase
pressure on the braking circuit
It effectively increasing the braking force on
the wheels
16. • Controls the speed of the car.

Travelling car braking system
start stop
AUTOMATIC BRAKING SYSTEM
17. FUNCTIONS OF HYDRAULIC VALVES
In position one the valve is opening
,pressure from the master cylinder is passed
right through to the brake.
In position two the valve blocks the line
,isolating that brake from the master cylinder
This prevents the pressure from rising
further should the driver push the brake
pedal harder
In position three, the valve releases some of
pressure from the brake
18. Advantage
It reduces the accident rate
It gives the alert to driver
Its maintenance is low
This technology gives safety
19. Disadvantage
Every car must and should have
Bluetooth to communicate with
each other
Due to the automatic braking
system the throttle valve get
damage
The automatic braking system is
some what costlier
20. • The Bluetooth technology is being widely
adopted by the Industry leaders.
• The possibility for new applications is very
exciting with this Versatile technology.
• It provides a simple, logical answer to all the
Problems-which is built a single common
radio into every mobile computer.
• It neither do companies have to worry about
WAN, nor do communication companies need
to worry about building external cables.
