Vehicle Display Position-Aware Content Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to ensure that critical information for the driver remains visible and accessible, as operations by passengers can inadvertently change or obscure the driver's display content, leading to reduced convenience and safety.
Innovation Solution
A vehicle display system comprising multiple display units, an operation unit, and a determination unit that assesses the occupant's position to dynamically manage content display, ensuring that the driver's display remains unchanged and critical information is preserved, while allowing flexible adjustments based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit accepts operations from any occupant to change displayed content, then the passenger can conveniently operate the display, but the driver's necessary information may be obscured or replaced
Solution Approach 1:
The patent applies local quality by differentiating operation acceptance based on occupant position. The determination unit identifies whether the operator is the driver or passenger, and the display control unit applies different display strategies accordingly. When the driver is detected, their selected content is displayed with higher priority and cannot be obscured by passenger operations. When the passenger is detected, they can operate the display freely. This position-based differentiation resolves the contradiction by giving the driver's information display rights priority protection while maintaining passenger operation convenience.
2Adaptability or versatility
If the display unit allows free operation by any occupant, then the system is highly adaptable to different users, but the driver's display content cannot be guaranteed to remain visible
Solution Approach 1:
The patent implements preliminary action by having the determination unit pre-identify the operator's position before processing the display operation. The system proactively determines whether the operator is the driver or passenger before allowing any display changes. This preliminary position identification enables the display control unit to preemptively protect driver information by not allowing passenger operations to obscure driver-selected content, thus preventing information loss before it can occur while still maintaining system adaptability.
3Ease of operation
If multiple display units are provided for different seats, then each occupant can have dedicated display control, but the system complexity increases
Solution Approach 1:
The patent applies universality by using a single shared display unit that can serve both the driver and passenger depending on the detected operator position. Rather than providing separate dedicated display units for each seat, the system uses one display unit with position-aware control logic. The determination unit identifies the operator, and the display control unit adapts the display behavior accordingly, allowing one component to fulfill multiple functions and reducing overall system complexity while maintaining occupant-specific control capabilities.

AI summary
A display device (100) for a vehicle includes: a plurality of display units (170, 180) which are mounted in the vehicle; an operation unit (110) that is configured to accept an operation of selecting content that is displayed on some or all of the plurality of display units; a determination unit (120) that determines a sitting position of a person who operates the operation unit; and a display control unit (130) that is configured to cause any one of the plurality of display units to display content on the basis of an operation that is accepted by the operation unit and a determination result of the determination unit. In a state in which content is displayed on any one of the plurality of display units, in a case where an operation of performing display of new content is accepted by the operation unit, the display control unit is configured to change a display aspect of the content that is already displayed on the basis of a determination result of the sitting position by the determination unit.
