Vehicle Feature Data Selection for Reliable Packet Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems determine various types of feature data with a uniform standard, leading to unreliable data being transmitted, which can compromise the reliability of the received data.
Innovation Solution
A transmission data generation apparatus that recognizes features around a vehicle using sensors, generating sequential feature data items with independent determination conditions for static and dynamic data to select high-reliability data for transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a uniform standard is used to determine transmission targets for various types of feature data, then the data transmission process is simple, but low-reliability data may be transmitted compromising overall data reliability
Solution Approach 1:
The patent divides the data determination process into separate first and second determination processes: the first determination process handles static feature data using a first standard, while the second determination process handles dynamic feature data using a second standard. This segmentation allows each data type to be evaluated according to its specific reliability characteristics without mixing criteria, thereby improving overall data reliability while maintaining manageable complexity through structured separation.
Solution Approach 2:
The patent applies different determination standards (first standard and second standard) to different types of feature data (static and dynamic) based on their local characteristics. Static data such as traffic light position and structure use one evaluation criterion, while dynamic data such as illumination states use another. This localized quality approach ensures each data type is assessed by the most appropriate standard for its reliability profile.
2Reliability
If all sequential feature data items are transmitted without selective determination, then data completeness is maintained, but transmission bandwidth is wasted on low-reliability data
Solution Approach 1:
The patent performs preliminary determination actions before transmission by evaluating whether sequential feature data items satisfy the first or second determination standards. This preliminary filtering identifies and selects only high-reliability data items for transmission, preventing low-reliability data from being sent while maintaining completeness of important information. The determination processes act as a pre-screening mechanism that preserves data quality without unnecessary transmission of redundant or low-value data.

AI summary
In a transmission data packet generation apparatus, a transmission-target data determiner determines, when each of sequential feature data items includes a static data item so that sequential static data items as the sequential feature data items are defined, whether a first determination condition for identifying one of the sequential static data items as one or more transmission targets is satisfied. The transmission-target data determiner determines, when each of the sequential feature data items includes a dynamic data item so that sequential dynamic data items as the sequential feature data items are defined, whether a second determination condition for identifying one of the sequential dynamic data items as the one or more transmission targets is satisfied. The first determination condition and the second determination condition are independent from each other.
