Vehicle to Vehicle Communication

As the number of vehicles on the road is increasing, the danger of these vehicles being involved in accidents is also increasing. Automotive engineers and vehicle safety experts are looking for ways that would help curb accidents and Vehicle to Vehicle (V2V) communication is definitely a promising technology. Vehicle to vehicle (V2V) communication is a technology that allows vehicles on the road to communicate with each other with the intention to inform the other of a possible collision. Applicable mainly for the safety of vehicles that ply on the roads, the technology helps vehicles communicate and alert the drivers to take corrective action. The data that may be exchanged between vehicles could include the position, speed, brake status, turn signal status and steering angle and throttle position of the vehicle.

As per the surveys conducted by the National Highway Traffic Safety Administration (NHTSA), more than 75% of the car accidents can be avoided if the V2V technology is used. But for this system to be effective, it needs that the vehicles plying on the road are equipped with the ability to receive and transmit data. In addition, the protocol that would allow communication between vehicles need to be common. There would also be the requirement of several policies that would deploy the use of the technology on a large scale.

As can be understood the benefits of the system would not only be limited to preventing accidents or collisions between vehicles but also avoid collision of vehicles with pedestrians, intersections, or road-side objects like electricity poles etc.

According to the NHTSA, the V2V technology could be the future of cars not only for the self driving or autonomous cars but also for the human driven cars. The technology is considered as important as the other life saving technologies such as the electronic stability control, auto safety features and seatbelts. Automakers have already been working on the technology. The NHTSA has said that the benefits of the technology have been demonstrated not only under controlled test conditions but even in the real world.

Tests for the long term usage and success of the technology are in progress. The researchers are of the view that once these tests are in the positive and ready to be implemented on a large scale basis, they would urge the manufacturers to provide the system in the new vehicles being produced. Slowly the system would be tweaked to include old vehicles so that there are communicable abilities between the old and the new vehicles.

As of now, the NHTSA is conducting an analysis and evaluation of a pilot program that took a year to complete. Once the auto safety agency completes the analysis, it would publish a report that would have the complete information regarding the technical feasibility of the technology, the security and privacy aspects and most importantly the costs. Once the report is presented before the public for discussion, NHTSA proposes to begin working on the actual regulatory proposal to implement the technology in all new vehicles.
