Introduction

World is plagued by Accidents.

Human errors.

Need an alert for the driver.

Checking the speed of the car is important.

High speed leads to accidents…

Statistics

1 person dies every 6 minutes, 10 are injured in the

same time frame.

India's share of global car accidents is 10%

6 % of the world's road accident deaths happen in

India.

Bluetooth

Modulation used in Bluetooth is Gaussian Frequency Shift Keying.

Bluetooth can communicate with 8 other devices simultaneously .

Hence we can check the speeds of eight cars simultaneously.

Range of communication is up to 100 meters of each other.

100 mts.

Modulation in Bluetooth

Equipment

The group of eight devices is known as

piconet.

Piconet is a collection of Master and slaves.

The frequency of 2.4 GHz is shared among all

the devices in the piconet.

Master and Slave configuration

Piconet

Master is a device which controls all the

devices around it.

Slave is a device which is being

controlled by a master.

Working

If the distance between two vehicle is within the 100m

the Bluetooth devices get enabled.

> 100m

<=100m

If the distance come closer within 10m

the automatic braking system takes the control.

• After the speed of the car is reduced, the

hydraulic valves decreases the pressure on the

braking circuit, thus effectively decrease the

braking force on the wheels.

100KMPH 10KMPH

• During overtaking

Components

• Four main components of an automatic

braking system:

1)Speed sensors

2)Pump

3)Valves

4)Controller

Operation

• 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.

Automatic Braking Pump and Valve

A computer constantly monitors the distance between

each of these cars .

When it senses that the car is getting too close it

moves the hydraulic valves to increase the pressure on

the braking circuit.

It effectively increasing the braking force on the

wheels.

Function of Hydraulic Valve

• In case one, the valve is open; pressure from the

master cylinder is passed right through to the brake.

• In case 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 case three, the valve releases some of the pressure

from the brake.

Conclusion

• The Bluetooth technology is being widely adopted by

the Industry leaders.

• It provides a simple, logical answer to all the

Problems, which is, build a single common radio into

every mobile computer.

Any Questions???
