Remote Assistance Control for AV Operator Shortage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote assistance systems for autonomous vehicles face increased waiting times at assistance points due to unexpected events or shortages of available operators.
Innovation Solution
A remote assistance device that controls the driving of autonomous vehicles to prevent operator shortages by instructing vehicles to stop, change routes, or adjust speed when no operators are available, optimizing operator allocation and reducing waiting times at assistance points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are allowed to proceed normally to assistance points, then operational efficiency is maintained, but operator shortages occur leading to increased waiting times
Solution Approach 1:
The system performs preliminary actions by predicting operator availability and vehicle arrival times in advance, then proactively adjusting vehicle routes or schedules before operator shortages occur at assistance points, preventing waiting times rather than reacting to them
Solution Approach 2:
The system establishes a feedback loop that continuously monitors operator availability, predicts future shortages, and adjusts vehicle operations accordingly, using prediction results to inform real-time decision-making about route modifications and scheduling changes
2Loss of time
If vehicle operations are controlled to prevent operator shortages, then waiting times are reduced, but system complexity increases
Solution Approach 1:
The system enables self-service by using automated prediction algorithms and control mechanisms that independently adjust vehicle operations based on predicted operator availability, reducing the need for manual coordination and complex human-in-the-loop decision-making processes
3Reliability
If predictive control is implemented to manage operator availability, then assistance delivery is improved, but computational requirements increase
Solution Approach 1:
The system applies partial action by implementing predictive control only for vehicles and time periods where operator shortages are predicted, rather than continuously optimizing all vehicle operations, thereby reducing unnecessary computational energy consumption while maintaining assistance delivery reliability

AI summary
A remote assistance device for remotely assisting autonomous driving of an autonomous driving vehicle, includes a control unit configured to, when there is no available operator or when it is predicted that there will be no available operator that provides remote assistance to the autonomous driving vehicle, control driving of the autonomous driving vehicle so as to prevent occurrence of a shortage of operators at an assistance point where the autonomous driving vehicle receives remote assistance.
