The focus in ConnRAD, which is funded by BMBF, is the derivation, implementation and validation of a communication architecture to ensure resilience in connected and automated driving functions. The research conducted in ConnRAD should enable a proper reaction to malfunction in the system in different application fields/use cases and thus ensure the reliability of connected driving functions even with unknown communication partners on the one hand and uncertain communication data on the other hand. The selected connected driving functions include networked communication for safely navigating through intersections, reliable and trustworthy event notifications via V2X for highway scenarios, and teleoperation as use case for communication between the vehicle and a cloud backend via the public mobile network with real-time requirements. A more detailed project description and an overview of participating partners can be found on the official project website.

The Institute of Automotive Technology contributes especially with its expertise in the field of teleoperation to ConnRAD. The goal is to develop methods to increase resilience in teleoperation. Because of the high demands in a reliable, error-reduced and robust real-time communication between the control center and the vehicle within the direct control concept, the focus is on this approach. The methods examined include the parameterization and application of ‘Predictive Quality of Service’ (pQoS)predictions for the quality of the cellular connection, the assessment of the significance of data from the control center or the vehicle based on the available information and the ensuring of all necessary capabilities for the vehicle guidance throughout the entire teleoperation system, even in the event of system degradation. In addition to developing the methods, the Institute of Automotive Technology is also involved in the implementation of selected methods in a real test vehicle.
