Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote driving and other mobile systems face challenges in maintaining communication quality, which affects their operational efficiency due to factors like communication congestion, leading to unsatisfactory execution of remote driving and other functions.
Innovation Solution
A path setting apparatus that acquires communication qualities at various geographical locations and sets a path for mobile bodies to satisfy the required communication quality based on their operation modes, using a quality acquisition unit and a setting unit to determine the optimal route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the mobile body passes through areas with poor communication quality to reach the destination, then the path length or time may be reduced, but the communication quality deteriorates
Solution Approach 1:
The system changes the path selection parameter based on communication quality requirements. When communication quality is poor in certain areas, the path planning algorithm adjusts by selecting alternative routes that maintain adequate communication quality, even if the path length or time increases. This dynamic parameter adjustment resolves the contradiction between minimizing travel time and maintaining communication reliability.
2Reliability
If communication quality requirements are strictly enforced for remote driving operation modes, then communication reliability is improved, but the available path options are reduced
Solution Approach 1:
The path planning system dynamically adapts communication quality requirements based on the selected operation mode. For remote driving modes requiring high communication quality, the system enforces stricter path selection criteria. For modes with lower communication requirements, the system relaxes constraints and allows greater path flexibility. This dynamic adjustment of requirements based on operational context resolves the contradiction between reliability and adaptability.
3Reliability
If the mobile body operates in operation modes requiring high communication quality, then the functional performance is improved, but the operable areas are restricted
Solution Approach 1:
The system segments the operational space into zones with different communication quality characteristics and assigns appropriate operation modes to each zone. High-performance operation modes are restricted to areas with adequate communication quality, while areas with poor communication quality are designated for modes with lower communication requirements. This spatial segmentation allows the system to maintain high operation performance where possible while still utilizing the full geographic area through mode switching.
