Control Center Framework for Teleoperation Support of Automated Vehicles on Public Roads

Implementing a teleoperation system with its various actors and interactions is challenging and requires an overview of the necessary functions. This work collects all tasks that arise in a control center for an automated vehicle fleet from literature and assigns them to the two roles Remote Operator and Fleet Manager. Focusing on the driving-related tasks of the remote operator, a process is derived that contains the sequence of tasks, associated vehicle states, and transitions between the states. The resulting state diagram shows all remote operator actions available to effectively resolve automated vehicle disengagements. Thus, the state diagram can be applied to existing legislation or modified based on prohibitions of specific interactions. The developed control center framework and included state diagram should serve as a basis for implementing and testing remote support for automated vehicles to be validated on public roads.
