5G mobile comms enable cross-border automation of driving functions

Based on 5G networks and edge computing infrastructure, the project developed automated vehicle functions that use 5G-based sensors to sense the traffic situation in order to extend vehicle automation from SAE level 2 to 4. Tests were conducted within individual countries and across borders in Germany, Austria and Italy. Cross-border scenarios are a challenge for 5G networks. In this respect, the project can claim success: The technology developed within its framework demonstrated smooth roaming for drivers moving from one country to another. In addition, edge computing platforms coordinated the continuity of 5G services for cars traveling along a defined corridor.

Two Stellantis CRF (Centro Ricerche Fiat) vehicles demonstrated cooperative lane changes through connected, assisted, and automated driving along the 5G corridor and at the Italy-Austria and Austria-Germany borders. Cooperative maneuvers with other road users are enabled through enhanced vehicle perception. Sensor data is exchanged with surrounding vehicles via the 5G mobile network as well as via direct C-V2X communication.

For example, an automated lane change was tested in Kufstein on the German-Austrian border. Three BMW vehicles transmitted their position, speed and intention of a lane change maneuver via a 5G network to a BMW service. This service monitors, for example, ongoing traffic and the distance between vehicles, determines a recommended speed for all vehicles and selects an appropriate time for a lane change.

Project partners include network operators TIM, Magenta and Deutsche Telekom, radio tower operator INWIT (Infrastrutture Wireless Italiane) and technology companies Nokia, Qualcomm Technologies and NEC Laboratories Europe. Also involved in the project was the road operator of the A22 Brenner freeway.
