dSpace in Germany is working with Anritsu on a digital twin simulation environment that can improve the protection for vulnerable road users (VRU).

The two companies have developed a demonstration of road safety using the C-V2X 5G network for cooperative communications. VRU protection is actively being developed for roads and intersections to ensure safety and improve accident prevention, linking roadside sensors to advanced driver assistance systems (ADAS) sensors in vehicles.

The 5GAA automotive association has been investigating accident prevention methods by the use of 5G-network-based communication, which is based on cooperative communications to and from VRUs.

Unlike in-vehicle-based methods, it is expected that protection in blind spots (such as outside the effective detection range of vehicle-mounted sensors and building shadows) will also be possible via 5G network communication. To achieve this, the 5G communication to cooperative VRUs must be reliable, and the evaluation of QoS management and fault tolerance at the IP layer is a critical factor.

The demo solution provides a digital twin environment for real-world scenarios, so VRU protection testing can be started virtually when features are not yet available on the real vehicle. Anritsu will continue to develop this solution to improve the protection of vulnerable road users and contribute to the development of smart cities by setting up an advanced simulation environment using digital twins.

“Today almost 40% of fatalities on the road are people outside the vehicles: pedestrians, cyclists, road workers, children, and more. It is a priority for the 5GAA members to leverage C-V2X technologies to protect these Vulnerable Road Users. This Digital Twin technology demonstration shows how C-V2X communications can offer this great societal opportunity,” said Maxime Flament, CTO of 5GAA.

dSPACE’s PC-based simulator integrates environmental, infrastructure, sensor, and vehicle information using a PC. In this demonstration, VRU protection simulation is performed by reproducing the University of Michigan’s automotive test course with smart cameras and different road users.

V2X data messages generated by communication devices such as smartphones carried by vulnerable road users, such as cyclists and pedestrians, as well as sensor information from intersection cameras, are transmitted to an OEM application that displays VRU protection results on the vehicle side via 5G communication using Anritsu’s 5G base station simulator.

The test platform provides network simulation compatible with 5G radio access technology and provides a development evaluation and certification test environment for Telematics, Infotainment, and V2X.;
