Route Communication Quality Control for Remote Vehicle Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication quality issues between a vehicle and a remote driving device can deteriorate, preventing satisfactory execution of remote driving and other functions, even when the communication amount is reduced, due to factors like system convergence, affecting mobile objects' ability to follow planned routes.
Innovation Solution
A control device for mobile objects that acquires communication quality on planned movement routes and determines whether specific positions along those routes meet the required communication quality for function execution, allowing for notification and restriction of function activation to ensure reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication amount between vehicle and remote driving device is reduced, then communication efficiency is improved, but communication quality may be deteriorated due to other causes such as system convergence
Solution Approach 1:
The system performs preliminary acquisition of communication quality information along the planned movement route before the mobile object actually travels. This allows the system to predict communication quality issues in advance and make appropriate decisions about function execution, preventing communication quality deterioration from affecting remote driving operations.
Solution Approach 2:
The system establishes a feedback mechanism where communication quality information is continuously acquired and used to determine whether to execute remote driving functions. The determination result feeds back into the control decision-making process, allowing dynamic adjustment of function execution based on actual communication conditions along the route.
2Adaptability or versatility
If remote driving function is executed in areas with poor communication quality, then service coverage is expanded, but function execution reliability deteriorates
Solution Approach 1:
The system acquires communication quality information for the entire planned movement route in advance, identifying areas with poor communication quality before the mobile object arrives. This allows proactive decision-making about whether to execute remote driving functions in specific segments of the route, ensuring reliable operation only in suitable areas.
Solution Approach 2:
The system applies different execution decisions to different segments of the movement route based on local communication quality conditions. Remote driving functions are executed only in segments where communication quality meets required thresholds, while alternative arrangements are made for segments with poor communication, ensuring local adaptability throughout the route.
3Reliability
If communication quality determination is performed for entire planned route, then function execution reliability is improved, but processing time increases
Solution Approach 1:
The planned movement route is divided into multiple segments for communication quality assessment. The determination unit processes communication quality information segment by segment along the route, allowing efficient handling of large route data while maintaining comprehensive coverage. This segmentation reduces the computational burden compared to analyzing the entire route as a single unit.

AI summary
A control device of a mobile object is configured to execute a function using communication. The control device includes an acquisition unit configured to acquire communication quality on a planned movement route of the mobile object, and a determination unit configured to determine, based on the acquired communication quality, whether or not the planned movement route includes a position that does not satisfy communication quality required for execution of the function.
