Vehicle Head-Up Display Field of View Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display systems for vehicles are limited in providing comprehensive and accurate information to drivers, particularly failing to effectively display distance information between vehicles and deteriorating recognition abilities due to incorrect environmental data and limited field of view considerations.
Innovation Solution
A head-up display apparatus and method that divides a driver's field of view into a primary and adjacent field, analyzing various information types (vehicle, driver, and environmental) to prioritize and display information in descending order, using recognition enhancement methods like figures, characters, or color changes, and gaze guidance through alarms or visual cues to ensure accurate and timely information delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional head-up display shows only simple driving information within forward field of view, then device complexity is low, but information completeness deteriorates
Solution Approach 1:
The patent divides the driver's field of view into multiple regions (central field of view and peripheral field of view) and segments information display accordingly. Different types of information are displayed in different regions based on their priority and relevance to driving safety, allowing comprehensive information presentation without overwhelming the driver.
Solution Approach 2:
The patent extends the display from a single forward field of view to multiple spatial dimensions including central and peripheral regions. By utilizing the peripheral field of view alongside the central field, the system provides comprehensive information without requiring the driver to shift attention frequently.
2Loss of information
If head-up display provides comprehensive distance information between vehicles, then information completeness improves, but recognition ability deteriorates due to incorrect environmental data
Solution Approach 1:
The system continuously collects information about the driver's field of view characteristics and driving circumstances, then uses this feedback to dynamically adjust and refine the displayed information. This ensures that distance and environmental data are accurately represented based on actual observed conditions rather than incorrect assumptions.
Solution Approach 2:
The patent dynamically adjusts display parameters such as information priority, display position, and presentation format based on driving circumstances and field of view characteristics. This allows the system to optimize information accuracy and recognition ability by adapting to changing environmental conditions and driver needs.
3Measurement precision
If 3-D graphics are applied to improve recognition ability, then recognition ability improves, but field of view accuracy deteriorates because driver's field of view varies by characteristics and circumstances
Solution Approach 1:
The system dynamically determines the driver's field of view characteristics based on individual driver characteristics and current driving circumstances. Rather than using a fixed field of view model, the system adapts to varying conditions, ensuring that 3-D graphics and displayed information remain accurate and relevant to the actual driver situation.
Solution Approach 2:
The patent adjusts multiple parameters including field of view boundaries, information priority levels, and display positioning based on driver characteristics and driving circumstances. This dynamic parameter adjustment ensures that recognition ability is maintained while adapting to individual driver needs and varying environmental conditions.
4Loss of information
If head-up display shows all collected information, then information completeness improves, but ease of operation deteriorates due to information overload
Solution Approach 1:
The patent applies different display qualities and priorities to different pieces of information based on their relevance to driving safety and current driving circumstances. Critical safety information is prominently displayed in the central field of view with high visibility, while less critical information is placed in peripheral regions or displayed with lower priority, making the overall system easy to operate while maintaining completeness.

AI summary
Disclosed herein is a head-up display apparatus for a vehicle. The head-up display includes an information analysis unit, a first information determination unit, a second information determination unit, and an information display unit. The information analysis unit collects vehicle state information, driver state information, driving environment state information, driver gaze information, individual characteristic information and common characteristic information from a plurality of information collection units, and analyzes the collected information. The first information determination unit prioritizes the vehicle state information, the driver state information, and the driving environment state information. The second information determination unit determines a driver's field of view based on driver field of view information and driver individual and common characteristic information. The information display unit changes information to be displayed to the driver based on priorities and the driver's field of view, and then displays the changed information.
