Remote Driving Handover Control Under Communication Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for mobile objects face challenges in maintaining normal operation due to communication delays, which can become excessive and disrupt the remote driving process.
Innovation Solution
A remote operation device that detects communication delays and switches to a more suitable remote operation device when the delay exceeds a threshold, ensuring continuous normal operation by determining a switching destination based on predefined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote operation is performed through communication, then remote driving can be achieved, but communication delay increases to such an extent that normal remote driving cannot be maintained
Solution Approach 1:
The system performs preliminary actions by detecting communication delay time before it becomes excessive, and proactively switches to a standby remote operation device. The acquisition unit obtains information on standby devices in advance, and the switching control unit prepares switching decisions before the current device becomes unusable, thus preventing disruption of normal remote driving.
Solution Approach 2:
The system introduces an intermediary mechanism (standby remote operation device) that can take over when the current communication path fails. The switching control unit acts as a mediator that monitors communication quality and transitions control to an alternative device, ensuring continuous operation without direct human intervention during the transition.
2Reliability
If communication delay monitoring and switching mechanism is implemented, then remote driving reliability is maintained, but device complexity increases
Solution Approach 1:
The switching control unit autonomously monitors communication delay time and automatically determines when switching is necessary without requiring external intervention. The system serves itself by detecting its own communication status and executing switching decisions based on pre-established criteria, reducing the need for complex external control mechanisms.
Solution Approach 2:
The switching control unit performs multiple functions: it acquires information on standby devices, detects communication delay time, determines switching necessity, and executes switching operations. This multi-functionality consolidates what could be separate complex systems into a single integrated unit, reducing overall system complexity while maintaining reliability.

AI summary
A remote operation device that remotely operates a mobile object by communication includes processing circuitry configured to acquire information on non-prime remote operation devices that are allowed to remotely operate the mobile object by the communication; detect a communication delay time in the communication with the mobile object; determine whether or not the detected communication delay time exceeds a delay time determination threshold; determine, when it is determined that the communication delay time exceeds the delay time determination threshold, a switching destination remote operation device from among the non-prime remote operation devices depending on whether or not a switching determination condition is satisfied on a basis of the acquired information on the non-prime remote operation devices; and output switching instruction information for remotely operating the mobile object to the determined switching destination remote operation device.
