Toyota to launch 'talking' cars soon

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.

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

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.

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

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

Toyota says their DSRC system will use seven channels of the 5.9 GHz spectrum band that has been allocated for Intelligent Transportation Systems.

Granted, neither do the Wizards , but their collection of young talent at least makes them a little bit of a wild card. Yes, only a chance-Kevin Durant could take over any series and has a talented enough team to win without Curry.

Proponents have viewed V2V as a seemingly practical technology to prevent collisions between vehicles. This means the technology does not require a cellular data network that would cause users to accumulate additional carrier charges.

V2V and V2I applications utilizing DSRC have the potential to significantly reduce most types of crashes through real-time advisories on road conditions, traffic congestion, accidents, construction zones and even parking availability, alerting drivers to road conditions that may be hard to see. DSRC is based on industry standards, so Toyota vehicles will be able to communicate with other automakers' equipped vehicles, multiplying the safety benefits for all.

V2V technology, if in widespread use, might work in tandem with the sensors that allow automated vehicles to scan the roadways, adding a layer of redundancy.

"Three years ago, we pledged to have automatic emergency braking (AEB) in nearly every vehicle we sell by the end of 2017".

In Japan in 2015, Toyota and Lexus became the world's first automaker to sell and commercialize vehicles equipped with DSRC. The Associated Press reports a Toyota official said the vehicles equipped with the tech could send signals as far as 984 feet.

The US Transportation Department must decide whether to adopt a pending proposal that would require all future vehicles to have the advanced technology.
