Remote Support Priority Control for Autonomous Mobile Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for self-driving vehicles do not effectively manage the prioritization of tasks among multiple self-driving cars, leading to potential degradation in services when one vehicle requires remote operation, impacting others' performance.
Innovation Solution
A control method and device that receive remote support requests from self-driving cars, identify other cars, calculate task priorities based on task information, and transmit control commands to prioritize tasks, ensuring that cars with lower priority tasks are remotely operated without hindering those with higher priority tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote operator remotely operates a self-driving car that requires remote operation, then the first mobile body can be controlled, but service degradation occurs in other mobile bodies that are also being monitored
Solution Approach 1:
The system changes the parameter of task priority by calculating and comparing priority values for different mobile bodies. The control device dynamically adjusts operation priorities based on task information, allowing it to switch between monitoring and remote operation modes for different vehicles, thereby maintaining service quality while enabling necessary remote interventions.
Solution Approach 2:
The system implements dynamic priority assignment where the importance level of each mobile body's task is not fixed but can change based on current conditions. The control device continuously evaluates task information and adjusts the priority of remote operation requests in real-time, ensuring that critical services are maintained while allowing remote operation when appropriate.
2Loss of information
If the control device monitors all mobile bodies simultaneously, then comprehensive monitoring is achieved, but the system cannot effectively prioritize tasks when remote operation is needed
Solution Approach 1:
The control device changes the monitoring parameter from uniform to differentiated by introducing priority levels. It calculates priority values for each mobile body based on task information and adjusts monitoring intensity accordingly, ensuring comprehensive coverage while efficiently allocating remote operation resources to the most critical tasks.
Solution Approach 2:
The system segments the monitoring function by dividing mobile bodies into different priority groups. Instead of treating all vehicles equally, the control device categorizes them based on task importance, allowing simultaneous monitoring of multiple bodies while prioritizing remote operation support for high-priority tasks.
3Adaptability or versatility
If remote operation is provided for any mobile body requesting support, then all remote support requests are fulfilled, but service degradation occurs for other mobile bodies
Solution Approach 1:
The system changes the responsiveness parameter by introducing priority-based handling. Instead of uniformly responding to all remote support requests, the control device calculates priority values and adjusts the responsiveness accordingly, fulfilling critical requests immediately while managing less urgent ones to prevent service degradation in other vehicles.
Solution Approach 2:
The system implements feedback mechanisms where the control device continuously receives task information from mobile bodies, evaluates priority levels, and adjusts remote operation allocation based on this feedback. This closed-loop approach ensures that remote support is provided adaptively, maintaining service continuity while responding to actual needs.

AI summary
A control method according to the present disclosure is performed by a control device for use in remotely monitoring mobile bodies each of which autonomously performs a task, and includes: receiving, from a first mobile body included in the mobile bodies, a remote support request indicating a request for remote operation support; identifying a second mobile body different from the first mobile body; obtaining first and second task information about first and second tasks being performed by the first and second mobile bodies, and calculating priorities of the first and second tasks based on the first and second task information; and when the priority of the first task is lower than that of the second task, transmitting, to the first mobile body, a first control command for remotely operating the first mobile body without hindering the second mobile body from performing the second task.
