The move will deliver enhanced safety benefits to drivers, including increased road safety and efficiency, with better advances in connected- and automated driving systems.
Together with Lexus, Toyota will accelerate research into Dedicated Short-Range Communications (DSRC) systems, which would allow vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, or, as they are known in the industry, vehicle-to-everything (V2X). This includes location, direction and speed which is communicated to other vehicles.
The real-time information can provide drivers warnings about potential hazards such as icy conditions, traffic jams and accidents.
By 2021, Toyota says some of its models will come equipped with "vehicle-to-vehicle" communication technology that will allow its vehicles to "talk" to each other and its surrounding environment.
There is a pending proposal which the US Transportation Department is evaluating for future vehicles to use this new technology. The Obama administration proposed giving automakers at least four years to comply.
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". The detail of the proposal insisted all vehicles "speak the same language through a standard technology".
In 1999 auto companies were granted a block of wavelengths 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.More news: Constand Denies Defense Claim She Plotted to Extort Cosby
In 2017, General Motors began offering vehicle-to-vehicle technologies on its Cadillac CTS model, but it is now the only commercially available vehicle with the system.
Talking vehicles are being tested for more than a decade now, utilize short-range communications to transmit data up to 300 meters. The company said it hopes that by announcing its plans, other automakers will follow suit.
Toyota said as the technology does not require cellular or data network, vehicles equipped with DSRC do not incur any cellular network carrier charges.
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.
Last year, major automakers, state regulators and others urged the US Transportation Secretary to finalise standards for the technology and therefore protect the reserved spectrum, stressing the need to expand deployment and use of the traffic safety technology.
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.
