Demo proves interoperability between motorcycles, cars and infrastructure via C-V2X

July 06, 2018 // By Christoph Hammerschmidt
Carmaker Audi, motorcycle manufacturer Ducati, Sweden's telecom equipment supplier Ericsson, Austrian road marking systems manufacturer Swarco, Kaiserslautern University of Technology and Qualcomm CDMA Technologies announced the first live demonstration of C-V2X interoperability with direct communication between a motorcycle, vehicles and roadside infrastructure in Europe.

The companies that founded the Connected Vehicle to Everything of Tomorrow (ConVeX) consortium last year to conduct the first announced C-V2X study based on Release 14 of 3GPP (3rd Generation Partnership Project) held the demonstration in Ingolstadt. Involved were the Audi Q7 and Audi A4 road vehicles and a Ducati Multistrada 1200 Enduro two-wheeler with C-V2X technology using the Qualcomm 9150 C-V2X chipset solution. The showcase demonstrated common situations that can occur between motorcycles and vehicles and how C-V2X technology can be used to improve road safety.

Among the implemented functions is the "Intersection Collision Warning", in which a vehicle with C-V2X technology drives out of a non-priority road into an intersection and prevents the vehicle from colliding with a motorcyclist with priority rights. Another use case is "Across Traffic Turn Collision Risk Warning", which prevents a collision with a motorcycle and a car turning left.

In the field of V2X (vehicles-to-everything) automated communications applications, The C-V2X technology is competing against the C-ITS technology which includes DSRC and the IEEE802.11p radio standard. The argument in favor of C-ITS is that it is more mature while the friends of C-V2X argue that this technology offers a seamless integration into cellular radio networks (typically based on LTE or 5G).
