Ericsson and a group of European telco partners have successfully demonstrated the continuous availability of a collision avoidance system fitted in autonomous, connected cars in a test carried out across three European borders.
The tests are part of the 5GCroCo project supported by E.U. funding and were successfully conducted in vehicles crossing the German border from Forbach in France and Schengen in Luxembourg.
The tests relied on existing 5G cell sites and additional components provided by Ericsson. This established a 5G trial network that replicated on a larger scale the campus network approach, said the company.
Running on mobile edge computing infrastructure, the ACCA service was tested on connected cars provided by Stellantis and Renault. The system has been developed to detect potential road hazards, using information such as anonymous status data transmitted to the cloud by equipped vehicles in the vicinity.
As part of the project, Stellantis and Renault provided vehicles with the ACCA-connected service, allowing them to receive warnings about hazards. These can be traffic jams or broken-down vehicles blocking the road.
While broken down vehicles usually stay where they are, the end of the traffic jam is permanently moving. This is particularly dangerous if the end of the traffic jam is behind a curve or a hill.
The ACCA service detects the current location of the end of the traffic jam by analyzing information such as anonymous status data transmitted to the cloud by the vehicles in the vicinity.
In this way, the position of the end of the traffic jam is determined in real-time, and the vehicle adjusts accordingly.
