Towards a Driver Support System for Teleoperated Driving

Numerous problems regarding autonomous driving were solved in recent years. However, there are still limitations preventing the introduction of autonomous driving features beyond SAE level 3. A remote operator can be a promising fallback solution. Teleoperated Driving is the remote control of vehicles by a human operator located at an operation center. Existent infrastructure such as cellular networks has to be utilized to provide a functional solution. However, cellular networks suffer from variable bandwidth, variable delay and packet loss. Thus, a route planning based on previous network measurements is proposed. As network parameters vary over time, speed adjustments are suggested to allow the remote operator to react quickly enough in any way. It is shown that the approach can work in principle, but further long-term measurements are required to identify and eliminate potential issues.
