Remote Assistance Routing for Autonomous Vehicle Exceptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles may encounter traffic situations that contradict their programming, necessitating human intervention for route adjustments, especially in cases like lane closures where direct human oversight is not possible.
Innovation Solution
An autonomous vehicle service system comprising a display device, receiver, and controller that monitors data from autonomous vehicles and third-party road conditions, determining when assistance is needed and displaying information to allow for remote route updates, enabling operators to reroute vehicles safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous vehicles operate with full automation without direct human intervention, then productivity and extent of automation are improved, but reliability deteriorates when encountering counter-programmed traffic situations
Solution Approach 1:
A remote operator serves as an intermediary between the autonomous vehicle's control system and the external environment. When the vehicle encounters a counter-programmed traffic situation, the operator receives notifications, assesses the situation through transmitted vehicle data, and provides corrective routing instructions, thereby maintaining both automation and reliability
Solution Approach 2:
The system implements continuous feedback loops where the autonomous vehicle transmits status data to remote operators, who monitor for anomalies and provide corrective input when counter-programmed situations are detected, enabling the vehicle to adjust its routing while maintaining autonomous operation
2Reliability
If remote monitoring and assistance systems are implemented for autonomous vehicles, then reliability is improved through human intervention capability, but device complexity increases
Solution Approach 1:
The autonomous vehicle performs self-monitoring and self-reporting of its status and encountered situations. The vehicle autonomously transmits data when it detects counter-programmed traffic situations, reducing the need for complex continuous monitoring infrastructure and simplifying the overall system architecture
Solution Approach 2:
The system pre-establishes communication channels and protocols between vehicles and remote operators. Notification systems and data transmission frameworks are prepared in advance, so that when counter-programmed situations occur, the complexity of real-time system setup is minimized
Data Source
AI summary
An autonomous vehicle service system having a display device, a receiver, and a controller. The receiver is configured to receive transmitted data from an autonomous vehicle related to status of the autonomous vehicle and information from a third party related to road conditions. The controller is programmed to monitor the transmitted data related to the status of the autonomous vehicle and the road conditions, determine when the autonomous vehicle requires assistance based on the transmitted data, and, when the autonomous vehicle requires assistance, cause information related to the autonomous vehicle to be displayed on the display device.
