Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices in vehicles face challenges in maintaining high-priority data communication throughput, particularly in scenarios where communication environments deteriorate, leading to potential disruptions in critical control-system-related data communications.
Innovation Solution
The implementation of an information processing device with a communication control unit that predicts future communication throughput based on past data, prioritizes data communications, and adjusts throughput by delaying or stopping low-priority data transmissions to ensure continuous high-priority data communication, thereby maintaining the minimum quality of service for control-system-related information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication throughput is increased to improve data transmission speed, then productivity is improved, but reliability deteriorates when communication environment degrades
Solution Approach 1:
The system dynamically adjusts communication throughput based on predicted future throughput values. The communication control unit modifies transmission parameters in real-time according to changing communication conditions, transitioning from static to dynamic throughput management to maintain both speed and reliability.
Solution Approach 2:
The system performs preliminary actions by predicting future communication throughput before actual data transmission occurs. The throughput prediction unit analyzes past throughput data and environmental factors to forecast future conditions, allowing the system to proactively adjust priorities and allocate bandwidth before degradation happens.
2Ease of operation
If all data communications are treated equally, then ease of operation is improved, but reliability deteriorates for critical control-system-related data
Solution Approach 1:
The system segments data communications into different priority levels. The communication control unit divides all data transmissions into high-priority (control-system-related) and low-priority categories, applying different management strategies to each segment to ensure critical data receives preferential treatment while maintaining overall system simplicity.
Solution Approach 2:
The system applies local quality by assigning different quality levels to different data types. High-priority control-system-related data receives guaranteed throughput and preferential handling, while low-priority data receives best-effort service, creating localized optimization without system-wide complexity.
3Reliability
If communication throughput is reduced to maintain quality of service, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The system dynamically adjusts the balance between reliability and productivity by continuously monitoring communication conditions and predicting future throughput. When conditions allow, high throughput is maintained for productivity; when degradation is predicted, the system dynamically shifts to priority-based allocation to maintain reliability.
Solution Approach 2:
The system implements feedback mechanisms where the throughput prediction unit continuously analyzes actual throughput data and communication environment changes. This feedback loop allows the communication control unit to adjust priorities and allocation strategies in real-time, optimizing the balance between maintaining quality of service and preserving overall transmission productivity.

AI summary
An information processing device, having a communication unit for wirelessly communicating with an external device, includes: a throughput measurement unit for measuring communication throughput with the external device; a throughput prediction unit for predicting future communication throughput by using at least data of the measured throughput; a communication control unit for controlling data communication with the external device based on the predicted throughput; a communication determination unit for determining a type of the data communication with the external device; and a priority setting unit for setting priorities of communications for a plurality of the data communications based on the determined type, in which the communication control unit is for limiting the throughput for the data communication for which the set priority is low, in comparison with the data communication for which the set priority is high, when the future throughput is below a predetermined threshold value.
