3. These accidents can be avoided if only there was a
mechanism to alert the driver of approaching danger
This can be done by monitoring the distance betweeen
nearby cars and alerting the driver whenever the distance
becomes too short
INTRODUCTION
Since bluetooth devices are capable of
communicating with eight other devices
simultaneously we can monitor and check the speeds
of up to eight cars simultaneously ,thus preventing
accidents

ACCIDENTS IN THE WORLD

5. OPERATION
 Because of travelling at high speed there is a
possibility of accident.
 Bluetooth is a radio is a short distance ,low
power radio operating in the unlicensed
spectrum of 2.4Ghz and using a nominal
antenna power of 20dbm.

Every car should have mini computer to monitor the relative
position of the car

9. BRAKE SYSTEM COMPONENTS

10. AUTOMATIC BRAKE SYSTEM
*Four main components to an
automatic braking system:
1)Speed sensors.
2)Pump.
3)Valves.
4)Controller.
*On receiving the control signal from
the travelling car the computer inside
the car manipulates the signal and
gives control signal to the braking
system.

11. *In position one, the valve is open , pressure from the master
cylinder is passed right through to brake.
*In position two, valve blocks the lines 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 the pressure from the
brake.
VARIOUS FUNCTIONS OF HYDRAULIC VALVES

12. Within 10m
Sends warning signal Receives signal and control the speed of car
PRESENTATION OF IDEA
* when car a and b come close with in the range of 100m then both the Bluetooth
devices get enabled.
* If any one of the car comes too fast then Bluetooth device gives signal to another
car and it process the signal and gives it to the automatic braking system .

13. CONCLUSION
 Bluetooth communication device will thus be a small,
low powered radio in a chip that will talk to other
Bluetooth enabled products.
 Thus, this technology helps make the electronic devices
more friendly and helps address various other
problems like accidents
