Learn About Car To Car OR V2V Communication:

Vehicle to vehicle OR V2V Communication is technological innovation. It allows two vehicles to ‘talk’ or ‘communicate’ with each other. It is also known as ‘V2X’. With the help of this technology, a vehicle can connect to the other nearby vehicles and supporting infrastructure. So, the main aim of developing V2V technology is to improve road safety and reduce the number of accidents.Be

Why Vehicle to vehicle OR V2V Communication?

First of all, a careful study reveals that the majority of road accidents take place because the following vehicle does not clearly understand the actions of the vehicle ahead. Hence in exigency, the driver of the following vehicle fails to take an action that is complementary to the one taken by the front vehicle.



But, you can avoid the accidents if the vehicle travelling ahead is able to clearly communicate its actions to the following vehicle. To achieve this purpose, automotive engineers developed the vehicle to vehicle OR V2V communication system.

How Vehicle to vehicle OR V2V Communication works:

For any Vehicle to Vehicle/V2V Communication system, there are two important factors-



  1. The communicating vehicle(s)
  2. The roadside infrastructure with which the communication takes place

The actual communication takes place with the help of ‘Dedicated Short Range Communication (DSRC)’ wireless communication devices. As per the regulation in the United States, these devices work in the 5.9GHz band with a bandwidth of 75MHz which it separately assigned for the vehicular communication only. The approximate range of these devices is 1000m. DSRC devices communicate not only with the other vehicles but also with the road infrastructure. It includes road signals or informative nodes installed by the roadside.

In addition, when the vehicles equipped with V2V communication come in the connecting range of each other, they exchange information. It includes the position, speed, the direction of travel. It also informs the steering inputs being given by the driver and sudden change in driving conditions such as braking or lane change.
