Vehicle Navigation System Avoiding Poor Wireless Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During vehicle movement, especially in areas with poor network quality such as mountainous regions or tunnels, streaming services like online video conferences experience delays or interruptions due to inadequate wireless communication.
Innovation Solution
An information processing device that acquires a quality map of wireless communication for each planned travel route and area of a vehicle. When the route passes through an area with lower than predetermined communication quality, the device sends an alternative route that avoids this area to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle follows the planned travel route, then the travel path is straightforward and navigation is simple, but the network quality deteriorates in mountainous areas or tunnels
Solution Approach 1:
The system performs preliminary actions by acquiring quality maps of wireless communication areas in advance and storing them before the vehicle reaches those areas. When the vehicle approaches a region with poor network quality (mountainous areas or tunnels), the system has already prepared alternative routes and quality information, enabling proactive route adjustment rather than reactive response to maintain reliable network connectivity
Solution Approach 2:
The quality map serves as an intermediary that mediates between the planned travel route and the actual network quality conditions. This intermediary data structure allows the navigation system to compare the planned route against actual communication quality metrics and select alternative routes that pass through areas with better wireless coverage, thus resolving the contradiction between navigation simplicity and network reliability
2Loss of time
If the vehicle passes through areas with poor wireless communication, then the travel route is direct and shortest, but streaming services experience delays or interruptions
Solution Approach 1:
The system performs preliminary actions by acquiring quality maps of wireless communication areas in advance and storing them before the vehicle reaches those areas. When the vehicle approaches a region with poor network quality (mountainous areas or tunnels), the system has already prepared alternative routes and quality information, enabling proactive route adjustment rather than reactive response to maintain reliable network connectivity
Solution Approach 2:
The system applies the skipping principle by identifying and skipping segments of the travel route that pass through poor network quality areas (mountainous regions or tunnels). Instead of following the direct shortest path, the system selects alternative routes that bypass these problematic segments, ensuring continuous streaming service availability even if it increases overall travel time
3Reliability
If the system provides alternative routes to avoid poor network areas, then network quality is maintained, but the route becomes more complex and longer
Solution Approach 1:
The system performs preliminary actions by acquiring quality maps of wireless communication areas in advance and storing them before the vehicle reaches those areas. When the vehicle approaches a region with poor network quality (mountainous areas or tunnels), the system has already prepared alternative routes and quality information, enabling proactive route adjustment rather than reactive response to maintain reliable network connectivity
Solution Approach 2:
The system uses feedback mechanisms by continuously monitoring the vehicle's position against the stored quality maps and adjusting routes based on real-time network conditions. This feedback loop allows the system to dynamically select optimal routes that balance communication quality with route simplicity, avoiding overly complex paths while ensuring reliable connectivity

AI summary
A control unit configured to perform obtaining a quality map regarding the quality of wireless communication for each planned travel route and area of the first vehicle, and transmitting an alternative route that does not pass through the first area to the first vehicle in response to the planned travel route passing through the first area whose quality of wireless communication is lower than a predetermined quality.
