INTRODUCTION

Vehicle Communication Systems: This systems are an emerging types of networks in which vehicles and roadside units are the communicating nodes:  

-to provide each other as information, such as safety warning and traffic information, etc.

 

  

INTRODUCTION

Generally vehicular networks are considered to contain two types of nodes:  

-vehicle to vehicle (V2V)  

-vehicle to Roadside (V2R)

V2V COMMUNICATIONS

V2V(Vehicle to Vehicle ) is an automobile technology designed to allow automobiles to “talk” to each other.  

The system will use a region of the 5.9GHz band using wireless protocol standard IEEE 802.11p for various public safety services

It is designed to facilitate communication at distances of up to 1 km.

With a 360 degree awareness of the position of other vehicles

APPLICATIONS

  Safety related: collision avoidance, cooperative merging, etc  

Incident report: dissemination of data regarding accidents on the network or breakdown/ blockage of a link, etc  

Route Guidance: en-route guidance about the shortest path, route guidance for gas stations, etc  

Miscellaneous: green light prediction, parking space availability, etc.

V2V COMMUNIATION FOR SAFTEY

The dynamic wireless exchange of data between nearby vehicles for safety improvements.

By exchanging anonymous: • Vehicle-based data regarding position, speed, and

location  

Enables a vehicles to: • Sense threats and hazard with a 360 degree awareness

of   the position of other vehicles.

• Issue driver advisories or warnings• Take preventive actions to avoid crashes.

V2V COMMUNIATION FOR SAFTEY

Example : Accident Warning

If vehicles involved in an accident are equipped with short- range communication, they can send out a warning message to the following traffic e.g. to avoid mass collisions.

 

If the driver fails to take action, the V2V system could automatically apply the brakes to stop the car.

FUTURESCOPE

For the past decade, engineers from a host of auto companies—including Ford, GM, Honda, Toyota, Nissan, Daimler, Volkswagen Group, and Hyundai Kia—have been collaborating on the next step in vehicle safety. The system, called vehicle-to-vehicle (V2V) communications. It will allow cars to share data that can alert drivers to prevent the most common—and most fatal—multi-vehicle accidents on roads.

The idea behind V2V is fairly simple, and it’s based on technology that is already part of many new cars. Tested in a 3,000 car trial in Ann Arbor, Michigan over the past three years.

CONCLUSION

According to the National Highway Traffic Safety Administration (NHTSA), 76% of car accidents could be prevented with the help of V2V communication technology.

The National Highway Traffic Safety Administration (NHTSA) seemed poised to mandate the technology in every vehicle.

With this technology the rides would become more safer then ever before.
