Vehicular Display Guide Light for Warning Comprehension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers, especially beginners or those unfamiliar with the vehicle's systems, struggle to comprehend vehicle abnormalities displayed on head-up displays due to the complexity of the instrument panel and separate display units, leading to potential serious malfunctions or accidents.
Innovation Solution
A vehicular display system with a guide display unit and control unit that uses light emitting elements to guide the driver's attention from the head-up display to a secondary display region containing detailed information, using a flowing light pattern to indicate the direction of the detailed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed information is displayed on separate display units (instrument panel, monitor), then the head-up display can show simple warning symbols, but drivers cannot immediately comprehend the specific content of warnings
Solution Approach 1:
The patent merges the head-up display and instrument panel display into a unified display system where the same display unit serves both functions. The display unit can switch between displaying simple warning symbols for the head-up projection and detailed information for the instrument panel, eliminating the need for separate display units while maintaining both functions.
Solution Approach 2:
The display unit is designed with multi-functionality to serve dual purposes: it displays simple warning symbols that are projected onto the windshield for the head-up display, and simultaneously displays detailed information on the same unit for the instrument panel. This universal display unit resolves the contradiction by making one component perform multiple functions.
2Loss of information
If the instrument panel contains multiple instruments and warning lights at various places, then comprehensive vehicle information is available, but drivers cannot immediately determine which display to refer to when a warning occurs
Solution Approach 1:
The patent introduces a guide light as an intermediary element that visually connects the head-up display warning symbol with the corresponding detailed information on the display unit. The guide light acts as a mediator that directs the driver's attention from the warning symbol to the relevant information, eliminating the need for the driver to search through multiple instruments and warning lights.
Solution Approach 2:
The guide light utilizes color changes or light emission to indicate the location of detailed information. When a warning is displayed, the guide light changes color or illuminates to guide the driver's视线 to the specific area on the display unit where detailed information is shown, improving response time by providing visual direction.
3Reliability
If beginners or unfamiliar drivers encounter warnings on the head-up display, then they can see the warning symbol, but they do not understand how to comprehend the current situation
Solution Approach 1:
The patent implements preliminary action by providing visual guidance (guide light) that automatically activates when a warning is displayed. This pre-prepared guidance system is already in place and immediately directs the driver to the relevant information without requiring the driver to know how to operate or interpret the display system, making the system intuitive for beginners.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates efficient guidance for drivers to locate detailed information, improving comprehension of vehicle conditions and reducing the risk of accidents by visually linking the head-up display warnings to the relevant detailed information.
Implementation Method 1
The light projection unit guides light including visible information that is displayed on the display unit to a predetermined projection surface
Implementation Method 2
A vehicular display system with a guide display unit and control unit that uses light emitting elements to guide the driver's attention

AI summary
A vehicular display device includes a display unit that displays visible information and a light projection unit that guides light including the visible information displayed on the display unit to a predetermined projection surface, and displaying the visible information as a virtual image. The vehicular display device includes a guide display unit and a guide display control unit. The guide display unit indicates a relationship between at least positions of a first display region in which the virtual image is displayed by projection of the light projection unit and a second display region in which detailed information is displayed. The detailed information has an association with a content of particular information that is displayed on the display unit under a predetermined condition. The guide display control unit controls the guide display unit into a display state when the particular information is displayed on the display unit.
