Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating fuel efficiency in motor vehicles do not accurately account for route-specific information and cannot generate resource-efficient tracks, especially when mandatory stop points are involved, limiting their applicability in global fuel consumption control systems and failing to optimize resource usage during stops.
Innovation Solution
A method that collects and analyzes data associated with both the vehicle and the route, including mandatory stop points, to generate a resource-efficient track by creating a speed profile and evaluating resource efficiency, allowing for adjustments to reduce fuel consumption during stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the method uses only similar vehicles' data for fuel efficiency evaluation, then the evaluation is simple and focused, but the method cannot be applied in a global fuel consumption control system comprising multiple vehicles with different specifications
Solution Approach 1:
The patent transforms the evaluation approach by changing the parameters used for comparison. Instead of comparing only similar vehicles, the system uses standardized parameters (speed, acceleration, route conditions) that can be normalized across different vehicle types. This allows vehicles with different specifications to be evaluated on a common basis, enabling global applicability while managing complexity through parameter standardization.
Solution Approach 2:
The evaluation method is segmented into distinct components: route segmentation (dividing the route into portions with mandatory stop points), vehicle journey segmentation (collecting data for different journey portions), and evaluation segmentation (separate evaluation for moving and stopped portions). This segmentation allows the system to handle diverse vehicle data in manageable units, facilitating global application across different vehicle specifications.
2Measurement precision
If the method does not use specific portion of route information, then the evaluation process is simpler, but the accuracy of fuel consumption estimation is reduced
Solution Approach 1:
The route is segmented into distinct portions based on mandatory stop points, creating moveable portions and stopped portions. This segmentation allows the system to apply different evaluation methods to different route segments, improving fuel consumption estimation accuracy by accounting for the specific conditions of each segment while managing complexity through structured data organization.
Solution Approach 2:
The patent applies local quality by treating different route portions with different evaluation characteristics. Moveable portions are evaluated based on vehicle movement data, while stopped portions are evaluated separately considering idle consumption. This localized evaluation approach improves overall accuracy by capturing the specific fuel consumption characteristics of each route segment.
3Productivity
If the method does not generate resource-efficient tracks, then the system is simpler, but it cannot optimize resource usage during stops or reduce overall resource consumption
Solution Approach 1:
The system performs preliminary action by generating resource-efficient tracks in advance before the vehicle executes them. The track generation process considers mandatory stop points and creates optimized speed profiles beforehand. This allows the vehicle to follow pre-calculated efficient routes, improving resource efficiency without requiring complex real-time decision-making systems.
Solution Approach 2:
The patent implements feedback mechanisms where the actual fuel consumption is compared with the estimated consumption from the generated track. This feedback loop allows the system to evaluate the effectiveness of the generated tracks and refine future track generation, improving resource efficiency while managing complexity through iterative optimization.
4Productivity
If the method evaluates fuel efficiency without considering mandatory stop points, then the evaluation is simpler, but it fails to optimize vehicle movement and resource usage during stops
Solution Approach 1:
The vehicle journey is segmented into moveable portions and stopped portions based on mandatory stop points. This segmentation allows the system to evaluate fuel consumption differently for each portion type, optimizing resource usage by considering the specific characteristics of stopped portions (idle consumption) separate from moveable portions (travel consumption).
Solution Approach 2:
The patent applies local quality by providing differentiated evaluation for different journey portions. Stop points receive specialized evaluation considering idle fuel consumption and stop duration, while moveable portions are evaluated based on movement characteristics. This localized approach optimizes overall fuel efficiency by addressing the unique resource consumption patterns of stopped portions.
