Remote Driving Control for Handover Delay Suppression Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication delays occur in remote driving systems due to operations like handover of communication, affecting mobile objects such as vehicles, especially in specific areas like intersections where timely data transmission is crucial for safe navigation.
Innovation Solution
A control device for mobile objects that restricts operations inducing communication delays in designated suppression areas, such as near intersections, by using delay suppression tables to manage communication handover and data transmission, ensuring timely data exchange for safe navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication handover operations are performed to maintain connectivity, then communication coverage is improved, but communication delay occurs in specific areas
Solution Approach 1:
The system applies different communication strategies to different spatial locations by defining suppression areas where handover operations are restricted. In these specific zones, the mobile object maintains communication with a single base station rather than performing handovers, thereby eliminating delays in critical areas while preserving handover capabilities in non-critical areas.
Solution Approach 2:
The system pre-defines suppression areas and pre-determines which operations should be restricted before the mobile object enters these zones. By having the control device identify suppression areas in advance and prepare restriction rules, the system可以避免 real-time decision delays and ensures immediate response when the mobile object enters a suppression area.
2Loss of time
If communication handover operations are restricted in suppression areas, then communication delay is suppressed, but communication flexibility is reduced
Solution Approach 1:
The restriction of handover operations is applied locally only within defined suppression areas rather than globally across all communication zones. This allows the system to maintain communication flexibility and normal handover operations in areas outside the suppression zones, thereby minimizing the impact on overall system adaptability while achieving delay suppression in critical areas.
3Loss of time
If data transmission is prioritized in suppression areas, then timely data exchange is improved, but system complexity increases
Solution Approach 1:
The control device pre-stores suppression area information and handover restriction rules in its memory before the mobile object enters these zones. This preliminary preparation eliminates the need for complex real-time calculations and decision-making processes, thereby achieving timely data transmission without significantly increasing system complexity during operation.
