Vehicle Display Device Mode Switching for Driver Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face the challenge of overwhelming information displayed to drivers, leading to distraction and difficulty in quickly accessing relevant information due to the limited display area and complexity of existing combination instruments.
Innovation Solution
A display device with a control system that allows for two modes: one displaying round instruments for intuitive information access and another mode hiding the instruments to expand the display area for complex information, using digital representations and adjustable image parameters to optimize information presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If comprehensive information is displayed in the combination instrument, then the driver can access navigation, telecommunication and driver assistance information, but the driver is distracted and cannot quickly take in the desired information
Solution Approach 1:
The display is segmented into multiple functional zones: a first display area for primary driving information, a second display area for additional information, and a third display area for further details. This segmentation allows comprehensive information to be organized in a structured manner that enables quick access to critical data while maintaining completeness.
Solution Approach 2:
The patent utilizes a multi-dimensional display approach by creating multiple display areas at different spatial positions and depths within the combination instrument. This dimensional expansion allows comprehensive information to be presented without overwhelming the driver, as information can be accessed by navigating through different display zones rather than competing for the same visual space.
2Ease of operation
If analog display instruments are used in the combination instrument, then the driver can quickly access information, but only a limited area for displaying further information is available
Solution Approach 1:
The patent merges analog and digital display technologies within the combination instrument. Analog round instruments are retained for primary information (speed, RPM) to ensure quick recognition, while digital display areas are integrated to provide additional information. This combination allows the system to leverage the strengths of both display types without being constrained by the limitations of either alone.
Solution Approach 2:
The combination instrument is designed with multi-functional display areas that can serve different purposes. The first display area handles primary analog information, the second display area provides digital supplementation, and the third display area offers additional context. This universal design allows the same physical space to deliver multiple types of information simultaneously, maximizing the effective display area while maintaining quick access to critical data.

AI summary
A display device for a vehicle for the display of information relating to the operation of the vehicle includes a display, at least one round instrument which is readable to a viewer in the area of the display, and a control device which controls the reading on the display and of the round instrument. The display device can be controlled by the control device such that the display device has a first display mode in which the at least one round instrument is displayed to the viewer and the display has a display area within the round instrument and a display area outside the round instrument, and the display device has a second display mode in which the at least one round instrument is not displayed to the viewer, the information which can be displayed by the round instrument is represented by a digital reading of the display, and the information displayed by the display in the first display mode within the round instrument is displayed in another display area of the display.
