Vehicle Display Focus Highlighting for HUD and Cluster Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face challenges in providing a suitable compromise between perceptibility and minimal driver distraction when switching between different operating states in head-up displays and instrument clusters.
Innovation Solution
A display system with a switching apparatus and actuator that allows manual operation of multiple displays and optically highlights the active state using illumination changes, minimizing distraction through intuitive actuation and glow effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If visual indications are made larger and more conspicuous to improve perceptibility, then the driver is more likely to notice the active display, but the driver becomes more distracted from the driving process
Solution Approach 1:
The patent applies local quality by creating a focused visual indication (operating focus) at a specific location on the display rather than making the entire display more conspicuous. This localized highlighting allows the driver to perceive the active display state clearly while minimizing overall visual distraction, as only the relevant area is emphasized with enhanced brightness, color, or contrast in that specific region.
Solution Approach 2:
The patent uses partial action by applying visual enhancement only to the portion of the display that needs to be highlighted (the active operating target) rather than the entire display. This selective application of brightness, color, or contrast changes provides sufficient perceptibility for the active state while avoiding excessive visual information that would distract the driver from driving.
2Object-affected harmful factors
If visual indications are made smaller and less conspicuous to reduce driver distraction, then the driver remains focused on driving, but the indication may not be recognized well or requires visual search
Solution Approach 1:
The patent employs color changes as a key mechanism for the operating focus, where the visual indication changes color or intensity to signal the active display state. This color differentiation provides strong visual recognition without requiring large size increases, allowing the indication to be conspicuous yet subtle enough to minimize driver distraction while ensuring clear recognizability.
3Adaptability or versatility
If additional displays are added to provide more information, then the system offers more functionality, but the head-up display contrast is reduced and occlusion increases
Solution Approach 1:
The patent applies segmentation by dividing the display information into separate operating targets (head-up display and instrument cluster) and using visual indications to guide the driver to the active one. This segmentation allows multiple display functions to coexist without reducing head-up display contrast, as each display maintains its own optimization while the operating focus mechanism manages information presentation.
