Vehicle Display Image Migration for Operational State Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices for vehicles often fail to intuitively communicate changes in operational states of vehicle functions, such as automatic lighting or safety features, making it difficult for occupants to notice these changes.
Innovation Solution
A display device with a first display unit at the meter display and a second display unit at the head-up display, where the controller migrates images between the two units to emphasize changes in operational states, using animation and different designs to ensure clear notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display information is provided only on the meter display, then the device complexity is low, but the occupant may not notice important operational state changes
Solution Approach 1:
The patent combines the meter display and head-up display into a coordinated notification system. When an operational state changes, the system displays an indicator on the meter display and migrates it to the head-up display, merging the functions of both displays to ensure reliable notification while maintaining a unified user experience.
Solution Approach 2:
The patent adds a spatial dimension to notifications by migrating display indicators from the meter display to the head-up display. This dimensional transition catches the occupant's attention through a visual change in location, enhancing notification reliability without significantly increasing device complexity.
2Reliability
If the head-up display is used for all notifications, then the notification effectiveness is high, but it interferes with the primary driving information display
Solution Approach 1:
The patent segments notification responsibilities between two displays: the meter display handles operational state changes and the head-up display handles primary driving information. By migrating notifications temporarily to the head-up display and then returning them, the system provides effective notification without permanently interfering with driving information visibility.
Solution Approach 2:
The patent implements dynamic display migration where notification indicators move from the meter display to the head-up display and can return. This dynamic behavior allows the system to adaptively use display space, providing effective notification while maintaining flexibility in information presentation based on driving context.
3Loss of information
If multiple display indicators are shown simultaneously, then the information completeness is high, but the visual complexity increases making it confusing
Solution Approach 1:
The patent extracts notification indicators from the main meter display and migrates them to the head-up display. This separation allows the meter display to maintain a clean, simple appearance while the head-up display handles additional notification information, reducing visual complexity while preserving information completeness.

AI summary
There is provided a display device for a vehicle, the display device including: a first display unit that is provided at a meter display and that is visible to an occupant of a vehicle; a second display unit that is provided at a projection surface of a head-up display, and that is above and adjacent to the first display unit in a line of sight of the occupant; a memory; and a processor that is connected to the memory, in a case in which an operational state of a function relating to the vehicle has automatically changed, the processor causing display of an image indicating the operational state on the second display unit, and then causing migration of display of the image to the first display unit.
