This communication technology makes it easier to prevent crashes on roads. It makes use of a vehicular ad hoc network, which is a wireless network that enables communication among automobiles and the sharing of data about their driving habits.
The data covers, among other things, the direction of motion, stability, braking, and speed. The purpose of this technology is to increase road safety by sending out notifications for incidents before a motorist may see or detect them.
How It Works
Vehicles may send, receive, and retransmit signals via a wireless mesh network thanks to car-to-car communication nodes. These nodes can gather traffic information many miles in advance, giving even the most careless drivers enough time to manage their journeys.
Real-time Communication
Here’s a potential scenario: There is an accident on the highway or there’s a growing traffic bottleneck. On the basis of their current sensors, nearby cars are able to detect this circumstance and transmit the information to nearby vehicles.
The vehicles that get this warning can then act quickly, alerting the driver or planning an alternate route, for example.
Even though car to car communication, which involves networking with infrastructure in addition to communication between vehicles, makes things a bit complicated, it results in a better traffic signal control system that adjusts to the volume of traffic based on the data gathered from the vehicles.
Also, by enabling automobiles to interact with roadside infrastructure like traffic signals and signs, an intelligent transport system uses data from vehicle-to-vehicle communication to enhance traffic management.
Cyber Security
Since wireless connections with the outside world provide a vulnerability to hacker attacks, v2v technology also concentrates heavily on the subject of cyber-security in automobiles.
False information may be provided by the modification of the data transmitted, which might have a substantial impact on traffic flow and road safety. It supports the creation of universal standards for the design and assessment of vehicle security systems.
V2V Technology Vs Self-Driving Cars
Additionally, car to car communication should have a greater impact than the more highly praised sophisticated vehicle automation technology. Though self-driving cars have the potential to increase safety, they are still in their infancy and lack experience.
Their sensors and software are too susceptible to being fooled by bad weather, unforeseen objects or conditions, or difficult city driving.
The impact on road safety from simply wirelessly networking automobiles together is expected to be far greater and more noticeable.
The development of the v2v network is still a difficult task.
Ten times per second, the computers in each car analyze the numerous readings sent out by other cars to determine the likelihood of an oncoming accident. A new wireless protocol and a specific area of the wireless spectrum are used by transmitters to verify one another.
When Will Networked Cars Become Reality?
The development of suitable communication technologies that will satisfy the requirements of vehicle networking is now underway. The Wi-Fi standard will be used in this scenario, allowing the creation of ad hoc vehicle networks at a range of several hundred meters.
The role of a router, which transmits data to other cars, is assumed by an involved vehicle.
Wi-Fi-based communication may be integrated with mobile communications technology, such as the UMTS technology that we are all familiar with from our smartphones, which helps in the realization of the widespread vehicle to infrastructure technology.
Every new automobile must have the latest mobile telephony interface and the automated emergency call system for vehicles, which is made necessary and available for new models. This may give the development of v2v technology a boost.
Vehicle to Infrastructure Technology
With the aid of this communication framework technology, many automobiles may exchange data with various equipment supporting a nation’s highway system. The vehicle to infrastructure technology is generally wireless and bi-directional, made possible by a network of hardware, software, and firmware.
Vehicle to infrastructure technology has the potential to boost transportation in a number of ways, from accident avoidance to increased energy efficiency. Sensors, radar, and cameras are frequently employed in today’s automation systems to provide drivers the ability to scan and assess their surroundings.
Although this technology is useful, it is unable to keep an eye on covert operations or, shockingly, what is going on in other cars. But vehicles may communicate with one another in real-time to share data using vehicle-to-vehicle and vehicle-to-infrastructure technologies, which enable them to anticipate events.
Conclusion
The primary goal of putting V2I systems on the road is safety since they make it possible to avert crashes and thereby save lives. These technologies make it simple to influence automatic emergency maneuvers including steering, stopping, and accelerating.
Given that vehicle to infrastructure is merely a concept, its implementation would result in a large decrease in both the number of traffic deaths and the cost of providing medical care.
