Vehicle Data Array Storage for Signal Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems for vehicle data require time-consuming searches within transmission frames to acquire vehicle information, making it inefficient for applications to find required data.
Innovation Solution
An information processing device that disassembles transmission frames into signals and stores their values in arrays, allowing for easier retrieval of vehicle information by referencing signal arrays rather than transmission frames, with additional elements for signal appearances and data classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If applications reference transmission frames directly to acquire vehicle information, then the system maintains data integrity and completeness, but the search time and processing complexity increase significantly
Solution Approach 1:
The patent segments transmission frame data into structured arrays organized by signal ID and reception sequence. Each array contains only relevant signal values, separating data by type and temporal order. This segmentation transforms the monolithic transmission frame structure into modular, easily searchable arrays, dramatically reducing search time while maintaining data integrity.
Solution Approach 2:
The system performs preliminary action by pre-organizing transmission frame data into structured arrays before applications need to access them. The data is disassembled, categorized by signal ID, and stored in reception sequence order in advance, so that when applications need information, it is already in an optimized retrieval format, eliminating the need for time-consuming searches through raw transmission frames.
2Loss of information
If the system stores all transmission frame data for complete information retrieval, then data completeness is maintained, but memory resource consumption increases
Solution Approach 1:
The patent applies local quality by organizing data arrays according to their specific characteristics - grouping by signal ID and arranging by reception sequence. Each array is tailored to store only the relevant data type with appropriate structure, rather than storing all data uniformly. This localized organization maintains complete information while optimizing memory usage through efficient data grouping and indexing.
3Reliability
If the array size is set to accommodate maximum transmission frames, then overspill is prevented, but memory efficiency decreases when fewer frames are received
Solution Approach 1:
The system implements dynamics by making the array structure adaptable to the actual number of received transmission frames. The arrays are configured with sufficient capacity to handle maximum expected frames, but only allocate and populate memory for the actual number of frames received. This dynamic approach ensures reliability by preventing overspill while maintaining memory efficiency by not allocating unnecessary memory when fewer frames are present.
