All About Vehicle-to-Vehicle Communication

What is Vehicle-to-Vehicle Communication?

V2V (vehicle-to-vehicle) is a communication technique that aids in crash avoidance. It makes use of VANETs (vehicular ad hoc networks), which are wireless networks that allow vehicles to communicate and share information about their driving habits. The data comprises speed, geolocation, braking, stability, and travel direction. This technology is critical for improving road safety by sending out incident notifications before a driver notices them.

Vehicle-To-Vehicle communication technology allows vehicles to transmit data using a mesh network that is wireless, to send and receive signals. These nodes can detect traffic conditions several miles ahead of a driver, enough time for drivers to manage their units.  Under the V2V umbrella, there is the Vehicle Systems for Infrastructure (V2I) which includes traffic signs and various fixed devices.

Current vehicle safety programs, such as embedded technologies that permit adaptive cruise control, blind-spot detection, rear parking sonar, and backup cameras, are likely to be less powerful than V2V technology. V2V technology provides omnipresent 360-degree awareness of surrounding risks, which improves performance and safety. The original generation of this technology would essentially inform the driver while not altering the vehicle’s motion to avoid a collision. The following implementations may improve the steering and braking systems, allowing for complete control of the vehicle’s behavior.

Vehicle-To-Vehicle Communication Technology

An intelligent transportation system is generally defined as a system that uses onboard car sensors to provide advanced information, data, and communication technology. The information will improve transportation safety while also lowering public transportation’s environmental effect. In dynamic driving settings, wireless devices are already being designed to communicate between automobiles and adjoining infrastructure.

Vehicle-To-Vehicle Communication can be carried out using WIFI or IoT. The capacity to combine data for the connection of autonomous vehicle operations has been made possible by technological breakthroughs. The following are some of the most modern wireless technologies that enable autonomous vehicles to stay connected:

  • Satellite-Based Global Positioning System (GPS)

It integrates object location and time references for accurate and consistent position tracking. Typically, this technology is employed to assist people in moving between predetermined locations.

  • Inertial Navigation System (INS)

With onboard sensors, this technology monitors and estimates a vehicle’s position, direction, and speed.

  • Laser Illuminated Detection And Ranging (LIDAR)

On-board laser detecting devices will aid a vehicle’s understanding of its surroundings and terrain. To establish the speed and relative orientation to its environment, precision measurements of distance to objects rely on reliable data. Sensors installed in traditional traffic equipment such as traffic cones and other roadside safety indicators communicate with onboard laser systems.

Vehicle-To-Vehicle Communication Protocol

Wireless communication technology underpins the vehicle-to-vehicle communication protocol. Because it is based on wireless technology, the V2V communication protocol is fairly simple to create. We can communicate with more than two automobiles using an NRF Transceiver Module. 3 strategies can be put to use to warn the driver: LCD alert, audio alert, and LED alert. The proximity sensor provides the distance measurement. A proximity sensor detects the presence of nearby items without making direct contact with them.

Vehicle-To-Vehicle Communication Applications

Among the most important vehicle-to-vehicle communication applications are:

  1. Information on traffic in real-time
  2. Roadside support tailored to your needs
  3. On highways, automobiles will monitor and change their position
  4. Warn drivers if they are drifting out of their lane
  5. If they get too near to the car in front of them, they will slow down

Vehicle-To-Vehicle Communication Advantages

  • Improving Traffic Management 

Vehicle-to-vehicle communication is essential for enforcing traffic laws as it facilitates traffic monitoring and management by using real-time vehicle alerts to relieve traffic congestion. Officials use communication with vehicles to divert traffic, track vehicle locations, obey speed limits, and adjust traffic schedules. For drivers, V2V communication helps them avoid traffic jams and keep a reasonable distance from other vehicles.

  • Driver Assistance

V2V communication allows drivers to have complete control over their vehicles. For drivers operating huge fleet vehicles or moving oversized cargo, timely warnings such as the height of a nearby bridge are extremely valuable. The technology may also aid in safe parking, such as parallel parking, which is made possible by delivering notifications about surrounding vehicles.

  • Improved Fuel Efficiency

Vehicle-To-Vehicle Communication allows for close formation driving, which improves fuel economy. The platoon’s leading truck is the pack’s leader, and all other vehicles must follow suit. All cars are forced to modify their speed and placement according to a communication stream by forming a continuous formation

  • Route Optimization

One of the main reasons fleets invest so extensively in fleet management systems is to optimize routes. This technology aids drivers in getting to their destinations faster. Vehicle-To-Vehicle Communication is intended to provide drivers with important travel information directly through installed devices, among other things. This technology can send information such as the location of the destination, maps, and route optimization advice.

  • Crash Prevention

The numbers of road accidents continue to rise as new motorways and high-speed cars are introduced. As a result, road safety is a top priority. Despite all efforts by stakeholders to raise awareness about the necessity of safe driving, human error continues to be the leading cause of road accidents.

Vehicle-To-Vehicle Communication Limitations

While vehicle to vehicle communication comes with a slew of benefits, this technology is no stranger to certain limitations to its utility and performance. Some of the reasons holding this innovation back are:

  • Privacy Concerns

Individual driver data is processed by the vehicle-to-vehicle integrated network. Private companies and the government can readily track automobiles because there are no concrete restrictions governing the technology. They can also monitor drivers and their driving patterns at the same time. Automated License Plate Readers (ALPR) can monitor and collect data involving automobiles that communicate with one another via V2V. If this data is hacked, it may jeopardize personal privacy and raise other security problems.

  • Security Risks

Any security failure caused by V2V-enabled vehicles has the potential to be disastrous, with business wars and criminality accounting for a significant portion of road hijacking. Comprehensive security measures are required for vehicle communication to be fully integrated. Losing control of an automobile to another person as a result of a hacked system could result in the car doors closing up or the engine exceeding the speed limit.

  • Liability Issues

The technology of V2V communication is still in its infancy, and clear norms are yet to be created. Liability considerations may arise from incidents involving automobiles equipped with V2V. If, for example, the V2V communication system prompts result in an accident, determining who was at fault in the first place would be difficult.

  • Potential Driver Distraction

Human intervention is required for vehicle-to-vehicle communication to work. To run the system, the driver must perform some action, like texting or talking on the phone. It’s still in the early stages of development, but there’s a lot of work to be done to guarantee that drivers aren’t distracted, which may lead to an accident.

Future Scope of Vehicle-To-Vehicle Communication 

In terms of mobility, V2V technology can help to alleviate traffic congestion in a variety of ways. First, the fact that cars connect with a central hub provides real-time traffic data to transportation authorities, allowing them to better manage their facilities to maximize efficiency and decrease congestion. The V2V communication system could potentially allow vehicles to collaborate on the roadway by moving closer together in a platoon with other vehicles traveling in the same direction. As a result, roadways improve capacity by accommodating more vehicles in the same amount of area.

Although we are still a long way from having a linked vehicle road transport system, there are technologies on the market today that try to bridge the gap between existing and V2V technologies. Adaptive cruise control uses radar to scan adjacent vehicles and adjusts speed accordingly. Some premium automobiles have lane departure warning systems that can alert you if your vehicle is drifting out of its lane. Both of these high-tech elements assist drivers in being more aware of their surroundings.

Before a connected-vehicle transportation system can be fully realized, a few obstacles must be resolved. All road cars must be outfitted with the technology, legislation must be enacted at several levels, and the issue of liability for automated systems must be addressed. However, there is no doubt that a connected vehicle system, in which vehicles and the roads they ride on are linked in ways we have never seen before, will be a part of our future. We cannot afford to ignore the tremendous possibilities for safer and more efficient roadways.
