Information Processing Device for Vehicle Data Pre-download
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices struggle to efficiently manage data downloads for vehicles moving into areas with low wireless communication quality, leading to delayed or interrupted streaming services and unnecessary communication costs.
Innovation Solution
An information processing device acquires a quality map of wireless communication for planned travel routes and areas, and proactively sends data used by vehicles in areas with low communication quality before the vehicle enters those areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data is downloaded in real-time during vehicle travel, then communication costs are reduced, but streaming service continuity is compromised in low-quality areas
Solution Approach 1:
The system performs preliminary actions by downloading data before the vehicle enters low-quality communication areas. The quality map prediction unit identifies upcoming poor-quality zones, and the control unit pre-downloads necessary data during high-quality periods, ensuring streaming continuity without unnecessary communication costs in good areas.
2Reliability
If all data is downloaded in advance regardless of route, then streaming service continuity is ensured, but communication costs increase due to unnecessary downloads
Solution Approach 1:
The system applies local quality by differentiating download strategies based on spatial location and predicted communication quality. Instead of uniform pre-download, the quality map prediction unit identifies specific low-quality areas along the travel route, and data download control is applied selectively to those regions, optimizing the balance between service continuity and communication cost.
3Quantity of substance
If data download is delayed until entering an area, then communication resources are saved, but service interruption occurs in low-quality areas
Solution Approach 1:
The control unit executes preliminary data download actions based on predicted future communication quality along the travel route. By analyzing the quality map before the vehicle enters low-quality areas, the system proactively downloads necessary data in advance, preventing service interruptions while optimizing download timing to avoid unnecessary communication in high-quality areas.

AI summary
A control unit configured to: acquire a quality map regarding a planned traveling route of the first vehicle and quality of wireless communication for each area; and send data used by the first vehicle in the first area to the first vehicle before the first vehicle reaches the first area in response to the planned traveling route passing through the first area where the quality of wireless communication is lower than a predetermined quality.
