The move will deliver enhanced safety benefits to drivers, including increased road safety and efficiency, with better advances in connected- and automated driving systems.
The models will come equipped with a Dedicated Short-Range Communications (DSRC) system that enables them to share vehicle information - such as speed and location - with other vehicles and pieces of infrastructure.
The data is broadcast up to 10 times per second to nearby vehicles, which can identify risks and provide warnings to avoid imminent crashes, especially at intersections.
Communication can also be enabled to provide helpful real-time information to drivers, such as potential hazards, slow or stopped vehicles ahead, or signals, signs, and road conditions that may be hard to see. This information can be used by other DSRC-enabled vehicles and devices to help drivers prevent collisions and improve traffic flow.
At the moment, the U.S. transportation department is considering whether to adopt a pending proposal that would eventually require all vehicles to be fitted with this advanced technology.
According to Reuters, communications systems between vehicles have been tested by U.S. carmakers for over a decade now.
Braun Stacey Associates Inc. Has $12.27 Million Holdings in AbbVie Inc. (ABBV)
AbbVie Inc. (ABBV ) stock price rose 42.66 percent over the past one year, while decreased -0.6 percent during the past 6 months. Since February 26, 2018, it had 0 insider buys, and 1 sale for $480,600 activity. (NYSE: ABBV ) rating on Monday, October 30.
In 2017 General Motors Co began offering vehicle-to-vehicle technologies on its Cadillac CTS model, but it is now the only commercially available vehicle with the system. The detail of the proposal insisted all vehicles "speak the same language through a standard technology".
In a statement, Toyota Motor North America CEO Jim Lentz said "By allowing vehicles' intelligent systems to collaborate more broadly and effectively through DSRC technology, we can help drivers realize a future with zero fatalities from crashes, better traffic flow and less congestion".
Toyota and Lexus became the world's first brands to use the technology in Japan, and it has been deployed in more than 100,000 vehicles since 2015.
The National Highway Traffic Safety Administration said previous year the regulation could eventually cost between $135 and $300 per new vehicle, or up to $5 billion annually but could prevent up to 600,000 crashes and reduce costs by $71 billion annually when fully deployed.
A broad coalition of auto companies, including Toyota and General Motors Co., urged U.S. Transportation Secretary Elaine Chao in November to support a "talking cars" mandate for all new passenger vehicles by 2023.
But the push for a vehicle-to-vehicle, or V2V, communications rule has stalled amid President Donald Trump's drive to deregulate, according to Bloomberg. Toyota aims at being the pioneer in this technology and also hopes that other manufacturers will follow and get in this technology in their cars. The system being tested by Toyota does not require a cellular or data network to work.
