Eco-run System Priority Display for Prohibition Reasons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eco-run systems fail to effectively inform users of the reasons for engine non-stop conditions, leading to user confusion and anxiety, and are not universally applicable as they require a vehicle navigation apparatus.
Innovation Solution
An eco-run system with a prescribing portion that prioritizes the display of eco-run prohibition reasons, a judgment portion to assess these reasons, and an informing portion to notify the user via a lamp or display unit, allowing users to quickly identify actionable and non-actionable reasons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the eco-run system displays all stop conditions including those the user cannot cope with, then the user can understand all reasons for non-execution, but the display becomes complicated and the user cannot quickly identify actionable reasons
Solution Approach 1:
The patent segments the stop conditions into two distinct categories: conditions the user can cope with (first group) and conditions the user cannot cope with (second group). This segmentation allows the display to present information in an organized manner, showing actionable items first while maintaining completeness of information.
Solution Approach 2:
The patent applies local quality by giving different visual priorities to different groups of stop conditions. The first group (user-copable conditions) is displayed with higher priority to draw user attention, while the second group (user-non-copable conditions) is displayed with lower priority, creating a hierarchical information structure.
2Loss of information
If the eco-run system provides detailed information about all prohibition reasons, then the user can fully understand the system, but the display unit becomes cluttered and difficult to read
Solution Approach 1:
The patent divides the display content into distinct segments based on user actionability. By segmenting stop conditions into copable and non-copable groups, the system maintains information completeness while organizing the display to reduce visual clutter and improve readability.
Solution Approach 2:
The patent performs preliminary classification of stop conditions before display, organizing them into priority groups. This preliminary action of categorization allows the display unit to present information in a structured format that reduces complexity while maintaining completeness.
3Device complexity
If the eco-run system uses a simple indicator to show execution status, then the system remains simple and cost-effective, but the user cannot understand the reasons for non-execution
Solution Approach 1:
The patent adds a new dimension to the indicator system by incorporating stop condition information display. Instead of using only a simple binary indicator, the system extends the indicator's functionality to include textual or symbolic representation of stop conditions, providing reason information while maintaining relative system simplicity.
4Loss of information
If the system displays copable and non-copable reasons together, then all information is provided, but the user cannot quickly identify which actions to take
Solution Approach 1:
The patent applies local quality by assigning different visual priorities to different types of stop conditions. Conditions the user can cope with are displayed with higher priority (more prominent position, different color, or larger font), enabling users to quickly identify actionable items while still providing complete information about all stop conditions.
Solution Approach 2:
The patent segments stop conditions into distinct visual groups based on user actionability. This segmentation allows users to quickly distinguish between copable and non-copable conditions, reducing the time needed to identify required actions while maintaining information completeness.

AI summary
The present invention is an eco-run system having an eco-run function that stops and restarts an internal combustion engine depending on a state of a vehicle. The eco-run system includes: table information that prescribes a relationship between a plurality of eco-run prohibition reasons and priorities in which a user is informed of the eco-run prohibition reasons; an eco-run ECU 10 that judges whether an eco-run prohibition reason occurs to the vehicle; and an eco-lamp 41 or a navigation apparatus that, when it is judged by the eco-run ECU 10 that the eco-run prohibition reason occurs to the vehicle, informs the user of the eco-run prohibition reason depending on the priorities prescribed by the table information.
