Vehicular Control Apparatus Road Data Weighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The infrastructure cooperative system using electric wave communication generates a large amount of data, leading to increased operation loads during information processing, as existing systems lack efficient methods to manage and process this data effectively.
Innovation Solution
A vehicular control apparatus is developed with an obtaining device to receive electric waves and obtain road data, and a weighting device to assign importance to each road data set, allowing for the selection and deletion of more critical information, thereby reducing the operational load during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all road data from electric wave communication is processed, then complete information is available, but operation load increases
Solution Approach 1:
The patent extracts only the necessary road data from the complete set of communication data by using weighting information to identify and retain only those data elements that are essential for determining service road entry, thereby reducing processing load while maintaining reliability
Solution Approach 2:
The patent applies different weighting values to different portions of road data based on their individual importance, allowing the system to treat each data element differently according to its specific relevance rather than processing all data uniformly
2Productivity
If weighting information is assigned to all road data, then data prioritization is achieved, but device complexity increases
Solution Approach 1:
The patent performs preliminary assignment of weighting information to road data before the actual data processing occurs, allowing the system to pre-organize data according to importance and avoid complex real-time decision-making during processing
