Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of vehicles equipped with ISG systems lack sufficient information about the operation and status of the ISG system, leading to misunderstandings and unnecessary requests for assistance or complaints.
Innovation Solution
An ISG display device and method that includes a driving information detecting unit, a control unit, and a display unit to inform drivers about the operation and any abnormalities of the ISG system, providing notifications on idle stops, restarts, system status, and maintenance needs through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the ISG system operates automatically without driver intervention, then fuel efficiency is improved through automatic idle-stop and restart functions, but the driver lacks sufficient information about system operation leading to misunderstandings and unnecessary support requests
Solution Approach 1:
The patent implements a feedback mechanism by providing a display unit that shows ISG operation status, idle-stop count, idle-time accumulation, and abnormality notifications to the driver. This feedback loop allows the driver to understand what the system is doing automatically, reducing confusion and unnecessary support requests while maintaining automatic operation for fuel efficiency
Solution Approach 2:
The display unit acts as an intermediary between the automatic ISG control system and the driver. It translates complex system operations into understandable visual information, bridging the information gap without requiring the driver to directly interact with or control the automatic idle-stop function
2Ease of operation
If the ISG system provides comprehensive operation information to the driver, then driver understanding and satisfaction are improved, but the device complexity increases with additional display components and information processing
Solution Approach 1:
The information display is segmented into distinct, manageable elements: ISG operation status, idle-stop count, idle-time accumulation, and abnormality notifications. This segmentation presents comprehensive information in an organized, easy-to-understand format without overwhelming the driver, maintaining simplicity while providing completeness
Solution Approach 2:
The display unit serves multiple functions simultaneously: showing current ISG status, displaying operational statistics (idle-stop count and time), and providing abnormality alerts. This multi-functionality consolidates what could be multiple separate systems into a single integrated display component, reducing overall device complexity

AI summary
An ISG (Idle Stop and Go) display device of an ISG vehicle may include a driving information detecting unit that detects driving information of the vehicle, a memory unit that stores notification about ISG of the vehicle, a control unit that executes the ISG and detects situations of an operation and an abnormality of the ISG by using the driving information of the vehicle which may be input from the driving information detecting unit, and receives the notifications about the ISG which correspond to the situations from the memory unit, and a display unit that may be controlled by the control unit to display the notifications about the ISG in accordance with the situations.
