How does v2v work

In Japan, certain Toyota models have V2V communication built in that conveys a few simple data points: location, speed, and heading. The technology might already be outdated, however. It could prevent crashes. The vast majority of car crashes are caused by human error. The U. It could ease traffic congestion. Imagine if all the individual data points from millions of cars were sent to a central hub. With so much real-time traffic data, transportation managers could adjust traffic light timing and redirect traffic to make rush hour flow more smoothly.

All this can get relayed back to your vehicle from other vehicles, so when a car stops suddenly in front of you, an early alert will give you that extra time to respond.

Even a half-second difference can be life or death. V2V technology, when implemented at a mass scale, will change the way we drive, and it will inevitably save lives. It will also become smarter over time, and make autonomous vehicles which are coming, like it or not even better. This amazing autonomous communication between our cars will work better when more vehicles are using it.

A lone Cadillac will sense only what is immediately around it, which is still a big deal. However, were a line of cars on the highway able to signal an accident or road hazard up ahead, then every driver in that line of cars would be able to ready him or herself in time to safely deal with the issue.

The technology can then employ visual, tactile, and audible alerts—or, a combination of these alerts—to warn drivers. These alerts allow drivers the ability to take action to avoid crashes. These V2V communication messages have a range of more than meters and can detect dangers obscured by traffic, terrain, or weather.

V2V communication extends and enhances currently available crash avoidance systems that use radars and cameras to detect collision threats.

Vehicles that could use V2V communication technology range from cars and trucks to buses and motorcycles. Even bicycles and pedestrians may one day leverage V2V communication technology to enhance their visibility to motorists.
