Vehicle Display Control for Unconfirmed Object Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems inaccurately attribute objects near the host vehicle, leading to passenger misunderstanding, particularly in conditions like bad weather or distance, which can cause driving confusion.
Innovation Solution
A vehicle display control system that uses sensors to acquire peripheral information, recognizes object attributes, and displays unclear attributes with specific images indicating uncertainty until confirmation, adjusting transparency, shape, and size based on probability and confirmation status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If all objects with unclear attributes are displayed as 'sedans' in the virtual image, then the display is simplified and complete object coverage is achieved, but passenger misunderstanding of object attributes occurs
Solution Approach 1:
The patent applies local quality by differentiating the display treatment based on attribute confirmation status. Objects with confirmed attributes display their specific type (car, pedestrian, bicycle), while objects with unconfirmed attributes display a generic placeholder icon. This localized differentiation ensures that the display remains simple for confirmed objects while providing accurate information representation for uncertain objects, resolving the contradiction between display simplicity and attribute accuracy.
2Ease of operation
If object attributes are displayed without confirmation status indication, then the display is straightforward, but driving confusion may occur due to inaccurate attribute representation
Solution Approach 1:
The patent introduces an intermediary element - a generic placeholder icon - that mediates between the need for straightforward display and the need to convey attribute uncertainty. This placeholder icon serves as a visual intermediary that indicates 'object detected but attribute unconfirmed' without requiring complex display logic, thus maintaining ease of operation while preserving critical uncertainty information for driver awareness.

AI summary
A vehicle display control device, that acquires a peripheral situation of a host vehicle via a sensor; and, at a time of displaying an image showing the peripheral situation of the host vehicle at a display provided at a periphery of a driver's seat of the host vehicle, in a case in which an attribute of an object positioned at a periphery of the host vehicle is unclear, displays the object in a manner expressing that the attribute has not been confirmed, up until the attribute is confirmed.
