V2V Technology: Communication Between Vehicles

- Advertisment -

A vehicular communication system is an emerging type of network, in which vehicles and ground units are the communication nodes; exchanging information, such as safety warnings and traffic information.

What automaker doesn’t want zero accidents and zero casualties on their vehicles? Maximum safety is among their main objectives when they start the development of a new model. Advances in technology and the many driver assistance systems incorporated into vehicles are greatly assisting in safe driving.

And in this way it is also essential to talk about the connected car.

Currently one of the main challenges for car manufacturers is to promote so-called “interconnected cars”. This innovation is built on wireless technology, supporting a high-bandwidth Ethernet-based wired backbone.

This highly evolved communication between vehicles is what is known as: “vehicle to vehicle”, also known as V2V and between the vehicle and the V2I infrastructure. And they define a new short-distance communication system between vehicles from different manufacturers.

The fact that two vehicles can “talk” to each other, will mainly serve to communicate unfavorable conditions in traffic, accidents on the road, obstacles, preferences of passage, traffic lights, cruise control, speed control, warning of road works , passage of an emergency vehicle.

In addition, if a vehicle was not connected to the Internet and another nearby was, the former could use the latter to transmit a public status notification or an emergency alarm, through the latter.

Purpose and advantages of V2V technology


Currently, vehicles incorporate a large number of instruments and technologies to facilitate driving and improve passenger safety: GPS, ultrasound, vision cameras, etc., but in all cases, the distance is quite limited and they cannot “see” past a nearby obstacle.

V2V communication enables various vehicles to send messages to each other via wireless transmission, using a dedicated part of the “electromagnetic spectrum,” as well as a new wireless standard, 802.11p. Offering in such a way, a Wi-Fi access point in the car and around it.

It allows vehicles to transmit and receive multi-directional messages (up to 10 times per second), creating a 360-degree “awareness” of other vehicles in the vicinity. By itself, vehicles equipped with the appropriate software can employ messages from surrounding vehicles to determine crash threats, then the technology can employ visual, tactile, and audible alerts or a combination of these to warn drivers.

Of course, for the implementation of V2V technology to be effective, it is necessary that a significant volume of vehicles incorporate this type of connectivity and that its operation be totally reliable. In addition, data transmission must be carried out with dizzying speed and with powerful cloud systems capable of processing information in a matter of moments.

The vast majority of automotive companies are working to incorporate this communication concept with V2Vs, such as Cadillac, General Motors, Honda and Toyota. For example, Toyota in Japan has developed a security system for vehicle-to-vehicle communication called ITS Connect, which can be found on Crown and Prius models.

Although this technology is focused on cars, trucks and motorcycles, it is possible that in the future bicycles and pedestrians will one day use this type of communication to improve their visibility for drivers.

These security systems, which have been introduced as new options to protect occupants, have finally become mandatory standards for the new vehicle models currently appearing on the market.
