Vehicle Display Control for Speed and Distance Range Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems can lead to drivers erroneously perceiving that moving speed or inter-vehicle distance control is not functioning correctly due to significant changes within predetermined ranges, causing confusion.
Innovation Solution
A displaying control apparatus that uses an electronic control unit to display images representing speed or distance ranges on a vehicle's dashboard, ensuring the vehicle remains within these ranges by adjusting the displayed image lengths to match range changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moving speed control or inter-vehicle distance control is executed with predetermined ranges, then the vehicle can maintain speed or distance within acceptable limits, but the moving speed or inter-vehicle distance changes considerably within the range causing driver confusion
Solution Approach 1:
The system provides visual feedback to the driver through a display device that shows the current moving speed or inter-vehicle distance relative to the predetermined range. The display includes a range indication showing the upper and lower limits, and a current value indication that moves within this range, allowing the driver to understand that fluctuations are normal and within acceptable bounds.
Solution Approach 2:
The patent introduces an intermediate visual representation (the display device showing range and current value) that mediates between the control system's internal state and the driver's perception. This intermediary translates the controlled parameters into an intuitive visual format that helps the driver correctly understand the vehicle's controlled state.
2Adaptability or versatility
If the moving speed or inter-vehicle distance is maintained within a certain range, then the control system can adapt to varying conditions, but the considerable changes within the range make the driver erroneously understand that control is not functioning
Solution Approach 1:
The display device continuously shows the current value's position within the predetermined range, providing feedback that reassures the driver that the control system is functioning correctly. The visual representation makes it clear that changes are occurring within expected boundaries, maintaining driver trust while preserving control flexibility.
Solution Approach 2:
The patent utilizes visual indicators (such as different display states or colors) to represent whether the current value is within the predetermined range, at the upper limit, or at the lower limit. This visual coding helps the driver quickly assess the controlled state and understand that variations are normal operational behavior.
Data Source
AI summary
A displaying control apparatus displays an image which represents a predetermined speed range by a displaying device of an own vehicle while executing a moving speed control, or displays an image which represents a predetermined distance range by the displaying device while executing an inter-vehicle distance control. While executing the moving speed control, the displaying control apparatus display the image representing the predetermined speed range such that the own vehicle or an image representing the own vehicle is displayed within the image representing the predetermined speed range. While executing the inter-vehicle distance control, the displaying control apparatus displays the image representing the predetermined distance range such that the own vehicle or the image representing the own vehicle is displayed within the image representing the predetermined distance range.
