Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing onboard fuel efficiency evaluation systems face challenges in accurately assessing fuel efficiency for short road segments, leading to fluctuating results that are difficult to visualize and interpret.
Innovation Solution
An information processing apparatus that acquires and generates fuel or power consumption data for longer sections than the road segments being evaluated, allowing for the calculation of moving averages and mapping of fuel efficiency information on a road map, thereby stabilizing the evaluation and improving visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fuel consumption data is collected for each individual road segment, then measurement precision is improved, but stability of evaluation deteriorates due to fluctuations in short segments
Solution Approach 1:
The patent combines fuel consumption data from multiple road segments to form a composite evaluation unit. By merging individual segment measurements into a collective evaluation set, the system maintains the precision of individual measurements while achieving stability through aggregation, resolving the contradiction between precise measurement and stable evaluation.
Solution Approach 2:
The patent performs preliminary accumulation of fuel consumption data across multiple road segments before conducting the final evaluation. This preliminary action of gathering and storing data from several segments allows the system to smooth out fluctuations and produce stable evaluation results while preserving the precision of individual measurements.
2Adaptability or versatility
If fuel efficiency evaluation is performed for short road segments, then adaptability to detailed route analysis is improved, but visualization clarity deteriorates due to fluctuating results
Solution Approach 1:
The patent segments the evaluation process into two levels: individual road segment measurement and composite evaluation unit analysis. This segmentation allows detailed route analysis at the segment level while maintaining visualization clarity at the composite level, preventing information loss by operating at multiple scales simultaneously.
Solution Approach 2:
The patent introduces a new dimension of evaluation by creating composite evaluation units that aggregate multiple road segments. This dimensional change from single-segment to multi-segment evaluation provides both detailed route analysis capability and improved visualization clarity, as the composite units smooth out fluctuations while preserving granular information.
