Over the past decade the NHTSA has been working with major automakers to produce new technologies that will reduce the amount of collisions. Collision detection systems have been implemented in various ways in the past few years. However, the newest system would incorporate all of the previously available features.
Some previous collision detection systems involve warning the driver if another car is wandering into their lane. Cruise control options that automatically adjust speed to keep a safe following distance from the car ahead. Even forward collision systems that take control of the vehicle and brake when a collision is imminent.
The draw back of most of these systems, is that they rely on sensors to see the other cars. If a car is speeding around a bend, the sensor won’t see it, so current collision systems will fail you when you need them most.
Vehicle-to-vehicle, or V2V as it is being referred to, utilizes wireless technology for cars to be able to ‘speak’ to one another from further distance and before the other car can be seen by a sensor or radar.
V2V systems will be broadcasting statistics to other cars with this type of collision system. Rate of travel, direction, and anything the other car would need to know to calculate possible collisions warn their respective drivers.
The practical application is safety as well as gearing towards the driverless car. Testing is being set up using 3,000 vehicles in Ann Arbor, Michigan. The research for such a small sampling pool may not properly determine if the system is perfected, but the purpose is to see how drivers react to the prompts and warnings of the system.
The obvious problem with any new automotive technology is that it will be several decades before it is regulated, implemented, and adopted as a standard. With this particular type of innovation, the problem is far more severe. The V2V system is literally only as effective as the number of drivers using it.
The benefits of V2V collision prevention systems are numerous, but until it becomes fully saturated and included with every vehicle we will not see a proper measure of success.
