5G self driving is going to make your cars smarter and safer

Self driving cars already have a feature of see and think for themselves. But a new technology that will run on the soon-to-be-launched 5G network promises to give them a more advanced skill, the ability to talk with each other.

The C-V2X, a communication technology using the same 5G network that comes on our phones, will allow vehicles to improve both functionality and safety with traffic signals and other roadside gears with each other.

Cars will not broadcast their location, speed and direction right now – some already do with today’s 4G networks. They will be able to interact to turn on stop signals or merge into lanes, the digital equivalent of human drivers who make eye contact. By chatting with a traffic signal, your car will be able to synchronize a journey with a green light. Vehicles could also talk among themselves to squeeze more cars on the road and build vehicles to improve fuel economy.

Technology should initially help traditionally powered cars – for example, warning you of collision risks or icy paths. Advocates say that it will truly shine by making autonomous vehicles more efficient and thus more practical. Smarter self-driving cars will be able to decide what to do on their own rather than slowing a person back to control or avoid problems.

“Adding additional meaning will unlock the full potential of self-driving technology,” said Maxime Flument, chief technology officer of the C-V2X5G Automotive Association.

The C-V2X is designed to overtake a two-decade-old effort called Dedicated Short-Range Communications (DSRC), which only achieved scattered success. V2X refers to vehicles that are communicating with everything – from vehicle to vehicle (V2V), vehicle to infrastructure (V2I) or vehicle to pedestrian (V2P). C means that communication takes place on the same cellular network technology that our phones use.

5G can also transfer more data than 4G, allowing cars to share sensor data such as video cameras and radars.”If you want to pass a large vehicle, there are sensor data from front of that vehicle, you can understand,” said Putzschler.
IHS Market analyst Christian Kim said the popularity of 5G would help automakers add network hardware to a car from an estimated $ 200 to $ 300. Built-in 5G cars provide streaming video, firmware updates and traffic accident information in the car. The C-V2X then comes along for the ride – not an advantage for DSRC.
Some drivers may be bald at the prospect of adding another monthly wireless network payment to their budget, so carmakers may offer to adopt several years of free service. But the C-V2X does not require a connection to a carrier-run network such as Verizon or AT&T. C-V2X cars can communicate directly.
That direct communication link is also faster than one that has to be circulated through the carrier network. And it helps to deal with the fact that 5G network coverage can be spotty and slow to come, even in countries like Germany to blanket every freeway.
Of course, C-V2X still has to win some important constituencies. Self-driving car companies such as Waymo from Google parent company Alphabet; General Motors-controlled cruise; And electric vehicle manufacturer Tesla is still in doubt and is conspicuously absent from the 5GAA’s roster.
Waymo said its cars are “designed to run on the roads as they are today” and that self-driving cars do not require 5G, but no further comment has been made. Rep. Millin Mehta said, “Cruise had a similar stance:” All our electric self-driving cars are built to run safely on today’s roads with today’s infrastructure. “


Increasing C-V2X Alliance

The 5GAA, a consortium backing C-V2X, had eight founding members when it debuted in 2017. It now has 120 members, Flomart said, including key players that include several industries.

Carmakers are members including Audi, BMW, Daimler, Ford Motor, GM, Honda, Hyundai, Nissan, Volkswagen and Volvo. So are technology companies like Intel, Samsung and Qualcomm; Auto electronics companies such as Alpine, Continental and Bosch; Network equipment manufacturers including Nokia and Ericsson; And carriers AT&T, T-Mobile, Verizon and Vodafone.

The C-V2X already works on today’s 4G networks. 3GPP, is an industry group that develops wireless network standards, has incorporated some C-V2X technology that allows cars to transmit basic driving information over 4G networks. Release 15 of 3GPP, an update to the 5G standard expected later this year, will support the download of videos and maps for cars, said Nokia’s head of V2X work, Uwe Puetschler.

Putzschler said that 16, released by mid-2020, would enable more radical C-V2X capabilities, such as letting multiple cars negotiate the best way to cross an intersection. This will require a faster response to 5G, known in the industry as low latency. Release 16 should be at least 10 milliseconds less than ten milliseconds, he said. The flare is also needed to integrate cars or trucks into a platoon.

Form government on board

C-V2X advocates should also reassure regulators, a process that takes time. In 1999, the US government engraved a valuable piece of airwaves near the 5.9 GHz frequency band for the first standard DSRC. C-V2X backers now want about a quarter of wireless spectrum.

The Federal Communications Commission is reviewing opinions regarding an exemption that could make room for the C-V2X.

In July, European regulators indicated that they were also interested in seeing how the C-V2X develops. Some Chinese cities are active supporters, and may actually be China where the C-V2X comes first.

The regulatory situation has created obstacles in the DSRC. Toyota, which remains a DSRC fan, “halted” its plan to make earlier technology in cars starting in 2021 because it required a commitment that the 5.9GHz spectrum would be protected, a company Spokesman Nathan Cox said. The chipmaker is promoting NXP DSRC and its European counterpart, WLALN, saying it is more mature than the C-V2X. Neither Toyota nor NXP are 5GAA members.
Nevertheless, the C-V2X is a powerful if less mature force. 5G will spread to billions of phones and thousands of mobile network access points, and the auto industry can turn that width and power off.
IHS Markit’s said that the DSRC battle was lost. More companies are investing in C-V2X and the telecom industry has a formidable lobby.
Last year, it was unclear whether the C-V2X would dominate the DSRC, Kim said. “Now, it’s very clear.”

FORD Self driving Car

Ford is among the companies that have already reached that conclusion. In 2022, Ford vehicles will get the C-V2X, making the carmaker one of the standard’s fastest advocates. After heavy DSRC investment, Ford described the C-V2X as faster, more reliable, and less expensive, according to Jovan Zagajack, manager of Ford’s connected vehicle platform and product team.
The C-V2X may even allow cities to eliminate traditional traffic signals, he said – although accommodating millions of cars without the C-V2X is a remote possibility, even if the regulator uses new cars. Start needing C-V2X.
C-V2X will supplement a car’s sensor with more data about traffic signals, road construction and emergency vehicles than pulling a self-driving car to pass a fire truck or ambulance May send an ambiguous signal. “Advanced C-V2X lets one access the whole ability of vehicles”
