WASHINGTON -- Toyota plans to start selling U.S. vehicles that can talk to each other using short-range wireless technology in 2021, potentially preventing thousands of accidents annually.
Toyota hopes to adopt the dedicated short-range communications systems in the United States across most of its lineup by the mid-2020s. Toyota said it hopes that by announcing its plans, other automakers will follow suit.
The Obama administration in December 2016 proposed requiring the technology and giving automakers at least four years to comply. The proposal requires automakers to ensure all vehicles "speak the same language through a standard technology."
Andrew Coetzee, group vice president for planning and strategy at Toyota, told Automotive News that the company’s move is designed, in part, to spur other automakers, governments and traffic-infrastructure providers to join in the effort despite the lack of legal mandates.
“Our commitment today is: No. 1 we are going to deploy the technology and No. 2 we would like others to join,” Coetzee said.
Automakers were granted a block of spectrum in 1999 in the 5.9 GHz band for "vehicle-to-vehicle" and "vehicle to infrastructure" communications and have studied the technology for more than a decade, but it has gone largely unused. Some in Congress and at the Federal Communications Commission think it should be opened to other uses.
In 2017, General Motors began offering vehicle-to-vehicle technologies on its Cadillac CTS model, but it is currently the only commercially available vehicle with the system.
Talking vehicles, which have been tested in pilot projects and by U.S. automakers 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.
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.
Toyota has deployed the technology in Japan to more than 100,000 vehicles since 2015.
The National Highway Traffic Safety Administration said last 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.
NHTSA said last year it has "not made any final decision" on requiring the technology, but no decision is expected before December.
Last year, major automakers, state regulators and others urged U.S. Transportation Secretary Elaine Chao to finalize standards for the technology and protect the spectrum that has been reserved, saying there is a need to expand deployment and uses of the traffic safety technology.
