Cell-to-everything vehicle: 360-degree view |

A car pulls away from a curb as a bicycle approaches down the road from behind. A speeding vehicle illegally bypasses a stationary school bus. An emergency vehicle approaches an intersection unseen by another vehicle.

These are common scenarios that lead to road accidents, and they are the ones companies are aiming to alleviate with new connected technologies.

On Tuesday, May 24, Audi provided an update on its work with mobility platform Spoke and other partners to use cellular vehicle-to-everything (C-V2X) technology to help prevent crashes between bikes and vehicles. cars.

Detect what other sensors can’t

Audi works with C-V2X which leverages LTE cellular signals and direct PC5 signals that do not rely on a cellular network to detect a cyclist, school bus or emergency vehicle and alert the car driver.

The company says the C-V2X might be able to do this in circumstances that could trigger other types of sensors, such as cameras, radars and lidars – bad weather, faded road markings and obstacles.

To protect bicycles, the technology being developed would provide visual and audible warnings to cyclists and motorists.

Paving the way for autonomous vehicles

In April, Audi announced it was working with Navistar to develop C-V2X technology for that company’s emergency vehicles and school buses. Here too, connected technology would provide real-time warnings to drivers of these vehicles and nearby Audi vehicles. It would also inform the driver of the car of the direction from which the emergency vehicle is approaching.

“While the transportation industry as a whole has made great safety improvements over the years, C-V2X technology is a major step towards safer mobility for drivers, students, paramedics, patients and more,” Audi said in a press release.

The company also indicated that developing these technologies for these use cases can also facilitate work on automated driving.

“In addition to bicycle safety use cases, Audi is also developing technology in hopes of increasing safety for school bus users, school zones and construction zones, with new advancements for emergency vehicles that are expected to arrive in the future,” the automaker said in a statement. Press release. “The combination of all these use cases and those to be defined, represents a level of connectivity necessary to enable automated driving, not yet available today.”

Reduce the cost of infrastructure

Other applications for C-V2X are being developed through a partnership between Cisco and Verizon. Among them is the use of C-V2X to improve safety at traffic signal-controlled intersections for last-mile delivery robots, robo-taxis, pedestrians, emergency vehicles and loaded trucks.

Enterprises are demonstrating the use of mobile edge computing (MEC), LTE connectivity, and IoT networking technology to power these use cases without the need for expensive roadside physical units to extend radio signals.

“This test is an important step in proving that the future of connectivity for IoT applications can be powered by cellular,” Verizon Director of Systems Architecture Krishna Iyer said in a press release.
