Toyota, Lexus to launch 'talking' vehicles in 2021

The technology will enable cars to send data on their location and speed to surrounding vehicles and roadside infrastructure to curb crashes. This data is broadcast up to 10 times per second to nearby vehicles, which can identify risks and provide warnings to avoid crashes. Talking vehicles, which have been tested in pilot projects and by United States carmakers for more than a decade, use dedicated short-range communications to transmit data up to 300 meters, including location, direction, and speed, to nearby vehicles.

DSRC, hich uses seven communication channels in the 5.9 GHz spectrum brand, allows vehicles to exchange anonymized data nearly continuously with other vehicles and with the environment.

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". After all, at some point all the vehicles on the road will have to communicate with each other and that means the need for a recognized industry standard. The company says most of its US models should have the feature by the mid-2020s.

DSRC transmissions enable vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications-collectively known as V2X.

Toyota is leading on automatic emergency braking, making it standard on all but four models.

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

"In that same spirit, we believe that greater DSRC adoption by all automakers 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".

Looking ahead, communication-based technologies such as DSRC can help provide greater benefits to drivers as automakers increasingly equip vehicles with additional sensors, including radars and cameras.

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

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

However, the push for V2V communications has stalled under the Trump administration.

Over the past 13 years, Toyota has collaborated with other automakers, infrastructure organizations and the U.S. Department of Transportation to develop DSRC V2X communication technologies. The US is a big market and certainly will benefit by this.
