Eco-drive Support Device Automatic Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eco-drive support devices fail to improve eco-consciousness in a motorized society as they require drivers to select an economy speed mode to receive feedback, missing opportunities to encourage fuel-saving driving operations from drivers unaware of or uninterested in the device's presence.
Innovation Solution
An eco-drive support device that calculates eco-drive support information and automatically notifies drivers of their driving eco-friendliness, even without a request, when predetermined conditions are met, such as driving on an expressway or maintaining a fuel-saving driving operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the eco-drive support device requires driver request or selection of economy speed mode to provide feedback, then the device complexity is reduced and ease of operation is improved, but the effectiveness in improving eco-consciousness deteriorates because drivers unaware of or uninterested in the device miss out on feedback
Solution Approach 1:
The notification control unit automatically determines and provides eco-drive support information without requiring driver action. The system monitors driving operations and autonomously decides when to notify the driver, making the system self-sufficient in promoting eco-consciousness rather than relying on driver initiative
Solution Approach 2:
The system implements automatic feedback by notifying drivers of their eco-friendly driving operations even without explicit requests. This continuous feedback loop reinforces positive driving behaviors and improves eco-consciousness by making drivers aware of their fuel-saving operations in real-time
2Device complexity
If the eco-lamp is controlled to light up only when the driver selects economy speed mode, then the device complexity is reduced, but the loss of information occurs because drivers who do not select the mode receive no feedback on their fuel-saving operations
Solution Approach 1:
The notification control unit autonomously monitors driving operations and determines when to provide feedback without requiring driver selection or input. The system serves itself by automatically identifying fuel-saving operations and notifying the driver, ensuring no feedback information is lost
Solution Approach 2:
The notification control unit performs multiple functions: it monitors driving operations, determines eco-friendliness, decides when notification is appropriate, and controls the notifying unit. This multi-functional approach ensures comprehensive feedback provision without adding significant complexity

AI summary
An eco-drive support device that notifies a driver of the eco-friendliness of a vehicle driving operation being performed by the driver includes: an operating unit that calculates eco-drive support information that indicates the eco-friendliness of the vehicle driving operation being performed by the driver; and a notification control unit that controls a notifying unit to notify the driver of the eco-drive support information, if there is a request from an input unit for notification of the eco-drive support information. In this device, the notification control unit controls the notifying unit to notify the driver of the eco-drive support information though there is not a request from the input unit for notification of the eco-drive support information, if a predetermined condition for providing the eco-drive support information is satisfied.
