Evaluation of Teleoperation Concepts to Address Automated Vehicle Disengagements

Core Concepts

Teleoperation can provide a fallback solution to address automated vehicle disengagements by enabling a human remote operator to support or substitute automated driving functions.

Abstract

The paper establishes a basis for comparing teleoperation concepts through a literature overview on automated vehicle disengagements and existing studies on teleoperation concept comparisons. An expert workshop is then conducted to evaluate different teleoperation concepts using a selection of automated vehicle disengagement scenarios and performance metrics.
The key highlights from the paper are:

Automated vehicle disengagements can occur due to failures in the perception, path planning, trajectory planning, or lane detection modules of the automated driving system. These disengagements require remote assistance to safely resume the vehicle's mission.

Literature review identified various teleoperation concepts, which can be categorized into Remote Driving (e.g., Direct Control, Shared Control, Trajectory Guidance) and Remote Assistance (e.g., Waypoint Guidance, Collaborative Planning, Perception Modification).

The expert workshop evaluated the teleoperation concepts based on metrics like task completion time, risk induced by human error, robustness against network instability, controllability, and mental demand.

The results suggest that a holistic teleoperation system should include Shared Control, Collaborative Planning, and Perception Modification concepts to address a wide range of automated vehicle disengagements in a safe and efficient manner.

Limitations include the assumptions made, the number of participants and scenarios evaluated, and the conceptual presentation of the teleoperation concepts rather than a real-world implementation.

Deeper Inquiries

How can the proposed teleoperation concept set be extended to address disengagements in end-to-end automated driving systems?

The proposed teleoperation concept set can be extended to address disengagements in end-to-end automated driving systems by incorporating concepts that specifically target the unique challenges and failures that may arise in such systems. End-to-end automated driving systems encompass the entire driving task without human intervention, posing different types of disengagement scenarios compared to traditional automated vehicles. To address this, the teleoperation concept set can be expanded by including concepts that focus on handling complex edge cases, handling failures in the decision-making process, and ensuring seamless handover between the automated system and the human operator. Additionally, concepts that allow for more dynamic and adaptive control of the vehicle in unpredictable situations can be integrated into the set to enhance the system's robustness and reliability in end-to-end automated driving scenarios.

What are the potential safety and ethical concerns with human operators remotely controlling automated vehicles, and how can they be mitigated?

There are several potential safety and ethical concerns associated with human operators remotely controlling automated vehicles. Some of these concerns include:

Latency and Communication Issues: Delays in communication between the operator and the vehicle can lead to accidents or errors in decision-making.
Cybersecurity Risks: Remote control systems are vulnerable to cyberattacks, which can compromise the safety and security of the vehicle.
Operator Training and Skill: Ensuring that operators are adequately trained and skilled to handle various scenarios and emergencies.
Ethical Decision-making: Human operators may face ethical dilemmas in critical situations, such as deciding between protecting the occupants of the vehicle or other road users.

These concerns can be mitigated through:

Robust Communication Systems: Implementing reliable and low-latency communication systems to ensure real-time control and feedback.
Cybersecurity Measures: Implementing strong cybersecurity protocols to protect the remote control system from unauthorized access and cyber threats.
Training and Certification: Providing comprehensive training programs for operators and ensuring they are certified to handle teleoperation tasks effectively.
Ethical Guidelines: Establishing clear ethical guidelines and protocols for operators to follow in challenging situations, ensuring they make decisions in line with safety and ethical standards.

How can the performance of the proposed teleoperation concepts be evaluated in real-world automated vehicle operations, and what additional insights could be gained?

The performance of the proposed teleoperation concepts can be evaluated in real-world automated vehicle operations through field tests, simulations, and controlled experiments. Key metrics such as task completion time, safety outcomes, operator workload, and system robustness can be measured to assess the effectiveness of the concepts. Additionally, collecting feedback from operators, passengers, and other road users can provide valuable insights into the usability and acceptance of the teleoperation system.
Some additional insights that could be gained from evaluating the teleoperation concepts in real-world operations include:

Adaptability to Dynamic Environments: Understanding how the concepts perform in dynamic and unpredictable driving scenarios.
Human-Machine Interaction: Evaluating the effectiveness of the user interface design and the communication between the operator and the automated vehicle.
Long-term Reliability: Assessing the long-term reliability and performance of the teleoperation system under various environmental conditions and usage patterns.
Regulatory Compliance: Ensuring that the teleoperation concepts comply with regulatory standards and guidelines for automated vehicle operations.
