3. What is V2V??
Vehicle-To-Vehicle (V2V)
is an automobile
technology designed to
allow automobiles to
"talk" to each other i.e., to
communicate with each
other.
It is worked on base of
Dedicated Short Range
Communications (DSRC).

4. History
■ Mainly it is motivated by ITS(Intelligent
Transport System).
■ According to World Health Organizations
(WHO), road accidents annually cause
approximately 1.2 million deaths worldwide. l
Also about 50 million persons are injured in
traffic accidents.
■ Western Europe a mere 5 km/h decrease in
average vehicle speeds could result in 25%
decrease in deaths

5. Why we want to V2V
On foggy days
On rainy days
What’s in front of that car
?

6. Need of V2V…..
■ To reduce the accidents.
■ To reduce the time of travel.
■ Extended driving vision.
■ To help others in making their
drive comfort.

7. Working of V2V
■ ULTERSONIC SENSOR
They are also known as transducers, they both send
and receive the signal.
It works on the principle similar to radar or Sonar
which evaluate attributes of a target by interpreting
the echoes from radio or sound waves respectively.
■ DISTANCE MEASUREMENT
Different techniques can be used to measure the
distance by using ultrasonic sensors.
Among them , continuous-wave and pulse- echo
technique are widely known. In continuous-wave
methods, the transmitter generates a continuous
output, whose echo is detected by a separate receiver.
In this case, accuracy depends on the measurement of
the phase shift between the transmitted and the
reflected wave.

9. Zigbee:
High level communication protocols using small, low-power digital radios based
on the IEEE 802.15.4-2006 standard for wireless personal area networks (WPANs)
ZigBee hardware typically consist of an eight bit Microcontroller combined with a
miniature transceiver a small amount (ex. 32 KB) of flash memory and RAM.
The ZigBee module is interconnected with the eight bit microcontroller.
The CMOS logic is used between the Microcontrollers and XBEE module, the
information is transmitted and received using ZigBee.
BUZZER :
We know about Buzzer…

10. Features
■ The main features are
Speed of the vehicle.
Break status.
Path history.
Path indication.
The other features are:
It gives the indication in the form of vibrating the seat,
voice or display. It specifies the features for a range of
1000m.
The personal information will not be revealed.
Emergency electronic break light warning(if there is sudden
braking from the front vehicle).
Blind spot warning.
Signal timing and phase are known.

11. Advantage
By this technology, people’s drive will be more
comfortable and easier.
The case of accidents will be very less.
Any problem occurred by one in driving will be
informed to others so they can be aware of it
while driving.
11
12. Disadvantages
Any small occur in the working of V2V
will leads to the total disturbance of the
one’s driving.
Some times signals given by it will not be
correct.
