Remote Driving Terminal Communication Status Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote driving systems using cellular wireless communication networks, accurate communication status information is crucial for effective control processing, but existing methods struggle to reliably acquire and utilize this information, especially when the number of samples from mobile terminals is low, leading to potential inaccuracies in control execution.
Innovation Solution
An information processing apparatus and method that preferentially uses either fixed terminal or mobile terminal communication status information based on the number of samples acquired, switching between the two to ensure accurate control processing. When sufficient samples are available, mobile terminal information is prioritized for high accuracy, and when samples are limited, fixed terminal information is used to maintain control processing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile terminal communication status information is used for remote driving control, then the accuracy of control processing is improved, but the reliability deteriorates when the number of samples is small
Solution Approach 1:
The patent introduces a sample number determination unit that acts as an intermediary between the acquisition unit and the determination unit. This intermediary evaluates whether the number of acquired samples meets a predetermined threshold before allowing mobile terminal information to be used. When samples are sufficient, mobile terminal information is used for high accuracy; when samples are insufficient, the system switches to fixed terminal information, ensuring reliability. This mediator resolves the contradiction by conditionally selecting the information source based on sample availability.
2Reliability
If fixed terminal communication status information is used, then the reliability of control processing is maintained, but the accuracy deteriorates compared to mobile terminal information
Solution Approach 1:
The patent implements a dynamic selection mechanism where the determination unit adaptively chooses between fixed terminal and mobile terminal information based on real-time sample number evaluation. The system is not static but dynamically adjusts its information source: when mobile terminal samples are sufficient, it switches to mobile terminal information for higher accuracy; when samples are insufficient, it reverts to fixed terminal information for reliability. This dynamic adaptation resolves the contradiction by optimizing the balance between reliability and accuracy based on current conditions.
3Measurement precision
If only mobile terminal information is acquired, then the accuracy is high when samples are sufficient, but the complexity of ensuring sufficient samples increases
Solution Approach 1:
The sample number determination unit serves as a simple intermediary that counts acquired samples and compares them against a predetermined threshold. This simple counting and comparison mechanism avoids complex sample acquisition strategies while ensuring that mobile terminal information is only used when sufficient samples are available. The intermediary adds minimal complexity but effectively manages the trade-off between accuracy and system complexity by providing a clear decision criterion.

AI summary
An information processing apparatus acquires first information on communication status of a fixed terminal device and second information on communication status of a moving terminal device, and determines which of the first information and the second information for executing predetermined control processing is preferentially used.
