How 2021 will be the year of V2X

As the lockdown seems to be coming to an end, more and more people will start going to work again, and once again the question of how we can make transport more efficient and safer will be burning.

The V2X market will force car manufacturers to change

National authorities have made decisions about supported technologies, making the global V2X market directions clearer. Generation Z is becoming a purchasing power, the Zoomers, who take connectivity and automation as granted. If all that weren’t enough, the requirements will also evolve so that some kind of vehicle communication solution will be a requirement for a five-star NCAP rating. Everything points in the direction of V2X. 

Good news: V2X technology is already one of the cheapest ADAS tool, and it’s getting more affordable. Chipmakers are creating new opportunities to offer V2X on different price segments. This means that the V2X market is set to expand rapidly. 

Another part of the story is that driver assistant systems must work under any circumstances.  It comes with the scary image of design flaws causing personal injury – litigation costs are extraordinary, not to mention recalls. Another good news we have:

V2X serves as an extra layer of protective gear

Reducingliability risks and the costs involved in the higher levels of self driving make OEMs use more and more sensors. Lidars are very expensive, and carmakers’ legendary cost-awareness is really a fight over the pennies. The price of computing power is also an issue, and it really does matter whether image information and other sensory data or simple messages need to be processed. We at Commsignia are focusing on offering high performance V2X solutions with a small resource footprint to enable the rollout of V2X on more cars.

How can V2X support existing ADAS systems? It is quite certain that connected and non-connected cars will share the same roads for a while, and we conducted extensive research in situations like that. One example is providing lane change assistance and drivable area recognition supported by V2X infrastructure. We’ve found that Collective Perception Messages (CPM) help self-driving trucks in lane change maneuvers, even when there are non-connected, human driven cars in the next lane. Such applications make the transition to self driving much smoother and safer. 

There’s another argument in favor of V2X: 

onboard sensors can only perceive the present, events that are happening right now. 

On the other hand, V2X offers a glimpse into the near future, warning drivers of events they may encounter on their route very soon. A good example of this is intention sharing, when the V2X infrastructure can predict that a vehicle crossing a driver’s route will violate the red light, risking an accident. Traffic lights play a central role in our most complex V2X project in Las Vegas, where self driving buses and self driving passenger car fleets show how the infrastructure and onboard sensors can work together.

We at Commsignia see a bright future for V2X in 2021, so we can make driving safer.

In this blogpost, we summarize the webinar presented at the Automotive Tech Week – Megatrends conference, organized by Wards Auto.
