Heads-Up Display Control for Autonomous Driving Attention Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving vehicles, existing display systems overwhelm occupants with excessive information, causing anxiety and annoyance by displaying multiple traffic lanes and vehicles, which is not effectively managed.
Innovation Solution
A display control device and method that acquires and displays information about peripheral objects within the vehicle's lane and objects requiring caution outside the lane, using a heads-up display and meter display to prioritize and emphasize critical information, reducing unnecessary data display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple traffic lanes and vehicles are displayed on the display section, then the information completeness is improved, but the occupant's anxiety and annoyance increase due to excessive information
Solution Approach 1:
The display information is segmented into two categories: peripheral target objects (in the subject vehicle lane) and objects requiring caution (outside the subject vehicle lane). This segmentation allows the system to present comprehensive information while managing occupant perception by separating routine information from critical information.
Solution Approach 2:
Different display strategies are applied to different types of objects based on their spatial location and importance. Objects in the subject vehicle lane are displayed normally, while objects outside the lane that require caution are selectively displayed only when necessary, creating localized information density variations that reduce overall cognitive load.
2Reliability
If all detected objects are displayed on the display section, then the situational awareness is improved, but the device complexity increases due to managing multiple display elements
Solution Approach 1:
The display system dynamically adjusts which objects are displayed based on real-time assessment of their importance and location. The information acquisition section and display control section work together to adaptively select objects requiring caution, creating a dynamic display that maintains situational awareness while simplifying display management through automated selection criteria.
Data Source
AI summary
A display control ECU includes an information acquisition section and a display control section. The information acquisition section acquires information relating to a peripheral target object that is present ahead of the vehicle and in a subject vehicle lane in which the vehicle is currently traveling, and information relating to an object requiring caution that is present outside of the subject vehicle lane and having implications for control during the autonomous driving. The display control section displays an image of the peripheral target object, regarding which information has been acquired by the information acquisition section on a heads-up display provided inside a cabin of the vehicle, and additionally displays on the heads-up display an image of the object requiring caution in a case in which information relating to the object requiring caution has been acquired by the information acquisition section.
