This document summarizes a seminar presentation on vehicle-to-vehicle (V2V) communications. V2V allows vehicles to communicate with each other to share information like speed and braking status. The goal is to reduce accidents by extending vehicles' sensing abilities. V2V works using dedicated short range communications and a mesh network topology. Future V2V systems may be able to take control of vehicles in dangerous situations and integrate with autonomous driving. V2V offers benefits like increased comfort and safety, but also challenges like reliability and potential driver distraction. Overall, V2V technology aims to improve the driving experience.

4. 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)
What is V2V???

5. lMainly it is motivated by ITS(Intelligent Transport
System).
lAccording 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.
lWestern Europe a mere 5 km/h decrease in average
vehicle speeds could result in 25% decrease in deaths.
History

6. Why we want to V2V
lWhat’s in front of
that bus ?
lOn foggy days
lOn rainy days
lWhat’s behind
the bend ?

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

8. A mesh network is a local area network
 wireless local area network
V2V is nothing about full mesh topology.
In a full mesh topology, each network node is connected
directly to each of the others.
Working of V2V

11. The main features are
Speed of the vehicle.
Break status.
Path history.
Path indication.
Features

12. 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.

13. ◦Road weather indications.
◦The weather data will be collected form the drivers
and will be sent to TMC’s and then the operates
specify about the weather of the roads.
◦With the help of this systems people can know the
traffic updates from the home easily.
◦If there is any car crashes ,police activities or
ambulance activities are present people can know it
from V2V so that they can give way for them.

16. At present, development of first generation of V2V
systems is underway. Function of these systems is
limited only up to giving warning to the driver.
However, these systems are unable to take any
corrective action in the input given by the driver.
The second generation of Vehicle to Vehicle systems
would be able to take control of the vehicle in danger
and provide the corrective action. These systems would
ultimately merge with the autonomous driving
technology.
Future

18. 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.
Advantages

19. 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.
Disadvantages

20. The technology of the V2V is one of the boon to the
automobile industry and the people.
As if now it is a prototype. It will be more easier and
helpful once it came to existence for the people for their
smooth drive experience.
