Vehicle Display Layout for Automatic Lane Change Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display control methods for head-up and meter displays in vehicles often result in different visibility characteristics, making it difficult for drivers to recognize necessary information when the same image is displayed on both, as the positioning and format of information differ significantly between the two displays.
Innovation Solution
A display control method that displays a first image on the head-up display with a vehicle icon and character string above it, and a second image on the meter display with a vehicle icon and character string below it, ensuring that the driver can easily grasp information from both displays by optimizing the layout and content for each display type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the same image is displayed on both the head-up display and the meter display, then information consistency between displays is improved, but driver recognition of necessary information deteriorates due to different visibility characteristics and display positions
Solution Approach 1:
The patent applies local quality by displaying different images on the head-up display and meter display according to their respective visibility characteristics. The head-up display shows images optimized for distant viewing with larger icons and simplified information, while the meter display shows detailed information suitable for close viewing. This resolves the contradiction by making each display locally optimized for its specific viewing conditions rather than forcing uniform content across both displays.
2Ease of operation
If different images are displayed on the head-up display and meter display to match visibility characteristics, then driver recognition is improved, but information consistency between displays deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the information display into two distinct segments: the head-up display segment for critical safety information and the meter display segment for detailed auxiliary information. Each segment is independently optimized for its viewing characteristics, allowing both displays to maintain their own information consistency while presenting different content types. This resolves the contradiction by segmenting the overall information architecture rather than forcing a unified display approach.
3Measurement precision
If character strings are arranged above the vehicle icon on the head-up display for visibility, then readability on head-up display is improved, but layout consistency with meter display deteriorates
Solution Approach 1:
The patent applies local quality by inverting the character string arrangement for the head-up display compared to the meter display. On the head-up display, character strings are positioned above the vehicle icon to optimize readability from a distance, while on the meter display, character strings remain below the icon following conventional layout expectations. This local adaptation resolves the contradiction by allowing each display to have its own optimized layout composition rather than enforcing uniform arrangement across both displays.

AI summary
A display control method used for a control system that controls a behavior of a host-vehicle to perform an automatic lane change includes, when the control system proposes to a driver to perform the automatic lane change, displaying a second character string that includes a first character string and a third character string on a meter display provided to a meter unit that displays a meter of the host-vehicle, when contents of the automatic lane change proposed to the driver by the control system include a first lane change and a second lane change following the first lane change, displaying the second character string, which includes the first character string and the third character string, in the first lane change, and displaying the second character string, which includes the first character string, but does not include the third character string, in the second lane change.
