Combining direct and indirect control for teleoperated autonomous vehicle

Combining direct and indirect control for teleoperated autonomous vehicle

Despite the rapid progress in machine learning, sensor technology, and communication infrastructure, in certain situations self-driving cars will need human situational assessment. For example, upon recognising an obstacle on the road a request might be routed to a teleoperator, who can assess and manage the situation with the help of a dedicated workspace. Besides providing adequate views to assess the remote traffic situation, the workspace needs to enable the operator to remotely move the vehicle. A common solution to this problem is direct remote steering. However, constraints of real-world traffic scenarios, in particular the availability of high-bandwidth mobile networks, have led to concepts not relying on ultra-low latency, such as path-planning or maneuver selection. Future work, should focus on integrating different remote operating concepts into a teleoperator workspace design in order to support the variety and complexity of real-world autonomous driving challenges.
