US Toyota, Lexus models will have DSRC connectivity from 2021

US Toyota, Lexus models will have DSRC connectivity from 2021

To date, more than 100,000 DSRC-equipped Toyota and Lexus vehicles were on the road in Japan, Toyota said. And in less than half a decade, you'll start seeing this tech on new Toyota and Lexus vehicles.

If all automakers equip models with V2V, it "will not only help drivers get to their destinations more safely and efficiently, but also help lay the foundation for future connected and automated driving systems", said Jim Lentz, CEO of Toyota North America.

Toyota stated that DSRC transmissions allow in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, which is collectively known as V2X. The Japanese giant plans to sell vehicles in the U.S. that can talk to each other using short-range wireless technology.

The technology sends information back and forth from a auto to another vehicle or infrastructure several times a second.

Some examples used to hype the system's capabilities are its planned functions in providing "helpful real-time information to drivers" like warning about slow or stopped vehicles, signals, signs, bad road conditions are anything else that "may be hard to see".

Toyota said adoption of the communication technology will let vehicles' intelligent systems collaborate more broadly and effectly, which should help reduce traffic accidents.

According to Reuters, communications systems between vehicles have been tested by USA carmakers for over a decade now.

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.


Toyota and Lexus became the world's first automaker to sell and commercialize vehicles equipped with DSRC back in 2015.

Toyota says that the DSRC tech has been tested through government-industry collaboration, and is already being used in some USA regions.

The Obama administration proposed giving automakers at least four years to comply.

The proposal requires automakers to ensure all vehicles "speak the same language through a standard technology".

General Motors started offering such a technology in its Cadillac CTS models past year, but it's still the only commercially available vehicle at the moment to have such a system.

Toyota will soon have its cars talking to each other. The company said it hopes that by announcing its plans, other automakers will follow suit.

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. The system being tested by Toyota does not require a cellular or data network to work.
