Cohda Wireless is developing a cellular vehicle-to-everything (C-V2X) turnkey solution for smart cities and automakers.

 

The company’s V2X software is being integrated with the Qualcomm Snapdragon Automotive 5G and 4G platforms to help build more intelligent, safer and less congested road transport systems.

 

More complete offering

 

The porting of Cohda’s software to the Snapdragon Automotive 5G and 4G platforms, in conjunction with the Snapdragon 2150 platform, will provide a more complete offering for C-V2X and deliver a faster time to market.

 

The 5G and 4G platforms feature integrated C-V2X direct communications, 5G and/or 4G cellular network connectivity, high-precision multi-frequency global navigation satellite system (HP-GNSS), radio frequency front-end, telematics software developer kit and Aerolink security functionalities to support major operators across key spectrum bands globally.

 

They are designed to provide support for rich in-vehicle experiences, precise positioning for lane level navigation accuracy, multi-gigabit vehicle-to-network cloud connectivity, vehicle-to-vehicle (V2V) and vehicle-to-roadside infrastructure (V2I) and direct communication to enable a broad set of end-to-end applications.

“Cohda Wireless’ V2X solution has been installed in two production vehicles giving Cohda practical experience in bringing automotive ITS solutions to industry”

“Cohda Wireless’ V2X solution has been installed in two production vehicles giving Cohda practical experience in bringing automotive ITS solutions to industry. In addition, as a roadmap item, Cohda will enable the C-V2X-Locate solution on the platform resulting in the most advanced, versatile and implementation-ready design,” said Fabien Cure, chief engineer, Cohda Wireless.

 

He added: “Cohda’s market leading vehicle location solution, V2X-Locate, solves the issue of inaccurate vehicle positioning in urban canyons where GNSS, even combined with RTK corrections, does not produce reliable vehicle positioning accuracy.”

 

Cohda’s V2X solutions support the two radio communications technologies under consideration globally.

 

Recent study

 

Cohda has also been involved in a study that shows how a connected intelligent transport system can detect the movement of people around blind corners and even through buildings by deploying collective perception messaging (CPM) – emerging technology that could save lives.

A study conducted in Sydney demonstrated that CPM can help prevent a variety of typical road accidents that occur when pedestrian are not easily visible to drivers or autonomous vehicles. The two-year study funded by the iMOVE Cooperative Research Centre involved scientists from University of Sydney’s Australian Centre for Field Robotics (ACFR), and engineers at Australian world-leading CAV technology company and Cohda Wireless.

 

CPM allows an intelligent transport system (ITS) station – or, for example in this research, an intelligent roadside unit (IRSU) – to share local perception information with others by using V2X communication technology. This emerging technology not only makes roads safer for motorists but also protects vulnerable users such as joggers, pedestrians, and cyclists.

The study involved three experiments including a controlled live roll-out in Sydney’s central business district.

 

The Sydney test showed how a connected vehicle using CPM sensory information from an intelligent roadside unit fitted out with high-tech gadgetry, including cameras and LiDAR laser sensors, was able to provide a connected autonomous vehicle (CAV) with the capability to “see” through buildings and around corners onto side streets to detect pedestrians hidden from its view.

 

In another test using cutting-edge Carla autonomous driving simulation software to recreate detailed virtual worlds, the research team demonstrated how a CAV using CPM took measures to safely interact with pedestrians crossing the road at a non-designated crossing area.

 

In the third and final test in a controlled lab traffic environment with a 55-metre stretch of straight road, the research team showed how a vehicle stopped for a pedestrian running to make a pedestrian crossing although he had not physically entered the crossing yet.
