Vehicle Display Priority System for Driver Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with multiple display units, drivers may miss important safety information due to the concurrent display of various types of information across different units, leading to a lack of prioritization of critical safety information.
Innovation Solution
An information display system that utilizes a sight line specifying component to identify the driver's line of sight, assigns priority orders to non-cognition display units based on the information they display, and executes a guide process to direct the driver's attention to the display unit with the highest priority order, ensuring that critical safety information is perceived.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple display units display different pieces of information simultaneously, then information completeness is improved, but driver attention distribution deteriorates and important safety information may be missed
Solution Approach 1:
The patent segments the multiple display units into two distinct groups: cognition display units (where the driver's line of sight overlaps) and non-cognition display units (where the line of sight does not overlap). This segmentation allows the system to prioritize and manage information display based on driver attention, ensuring that safety-critical information is directed to cognition display units while maintaining comprehensive information availability across all units.
Solution Approach 2:
The patent applies local quality by assigning different priority levels to different display units based on their cognitive accessibility. Cognition display units receive higher priority for safety information, while non-cognition display units display supplementary or less critical information. This localized differentiation ensures that important safety information is always presented where the driver can most reliably perceive it.
2Loss of information
If multiple display units are used to display comprehensive information, then information availability is improved, but driver cognitive load increases and attention management becomes difficult
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the driver's line of sight and dynamically adjusts information prioritization. The line of sight specifying portion detects where the driver is looking, and this feedback informs the priority order assignment portion to allocate safety information to the appropriate cognition display unit, thereby simplifying attention management through automated, real-time adaptation.
Solution Approach 2:
The patent performs preliminary classification of display units into cognition and non-cognition categories based on line of sight analysis. By pre-organizing which units are most accessible to the driver before information needs to be displayed, the system reduces cognitive load and simplifies attention management, as the priority assignment is based on pre-established spatial relationships rather than real-time decision-making.
3Reliability
If important safety information is prioritized on specific display units, then safety information perception is improved, but the system requires complex line of sight detection and priority assignment mechanisms
Solution Approach 1:
The patent employs a sight line specifying portion that automatically detects and analyzes the driver's line of sight without requiring manual input or complex external systems. The system serves itself by using the detected line of sight information to automatically assign priority orders to display units, thereby improving safety information perception while minimizing the added complexity through self-contained, automated functionality.

AI summary
An information display system displaying different information on each of a plurality of display units includes: a sight line specifying portion that specifies a line of sight of a driver; a cognition display unit specifying portion that specifies, as a cognition display unit, one of the display units being in a direction of the line of sight; a non-cognition display unit specifying portion that specifies, as a non-cognition display unit, a different one of the display units; a priority order assignment portion that assigns a priority order to the non-cognition display unit or displayed information; and a guide process execution portion that executes a guide process in which the line of sight is guided to the non-cognition display unit or the display unit.
