Lane Change Assist Display With Real Vehicle Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems during lane change assist control (LCA) fail to accurately represent other vehicles, leading to a mismatch between the displayed image and the actual surrounding situation, causing occupant discomfort.
Innovation Solution
The vehicle control device adjusts the color and shape of the other-vehicle image displayed on the in-vehicle display to match the actual vehicle, using surrounding information and vehicle-specific data to ensure accurate representation during LCA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the other-vehicle image is displayed in a standardized form without considering the actual form of the other-vehicle, then the display device can show consistent and simple images, but the occupant may perceive a mismatch between the displayed image and the actual surrounding situation
Solution Approach 1:
The patent applies local quality by making the display characteristics dependent on the specific context - when LCA is not executed, standardized images are shown for consistency, but when LCA is executed, the display switches to showing actual vehicle forms and colors to match reality. This localized adaptation of display quality based on operational context resolves the contradiction between display consistency and situational accuracy.
Solution Approach 2:
The patent implements dynamics by making the display mode changeable based on the execution state of LCA. The display device dynamically switches between two modes: a first mode showing standardized other-vehicle images during normal operation, and a second mode showing actual vehicle forms and colors during LCA execution. This dynamic adaptation allows the system to optimize for different operational requirements.
2Stability of the object's composition
If the other-vehicle image uses a different color than the actual other-vehicle, then the display can maintain a uniform color scheme, but the occupant may feel uncomfortable during LCA execution due to the mismatch with reality
Solution Approach 1:
The patent applies dynamics by making the color representation flexible rather than fixed. During normal operation, the display uses a uniform color scheme for consistency, but during LCA execution, it dynamically changes to display the actual colors of other vehicles. This dynamic color adaptation eliminates occupant discomfort while maintaining display uniformity during non-critical phases.
Solution Approach 2:
The patent directly applies color changes as a solution mechanism. The display device changes the color representation of other-vehicle images based on the LCA execution state - using standardized colors during normal operation and actual vehicle colors during LCA. This color adaptation strategy directly addresses the contradiction between display uniformity and realism.
3Device complexity
If the display device shows standardized other-vehicle images during LCA execution, then the display remains simple and consistent, but the occupant cannot accurately perceive the surrounding situation
Solution Approach 1:
The patent applies dynamics by switching the display complexity based on operational phase. During normal operation, the display maintains simplicity with standardized images. During LCA execution, it transitions to a more complex mode showing detailed vehicle forms and colors to ensure accurate situational perception. This dynamic complexity adjustment resolves the contradiction between simplicity and accuracy.
Solution Approach 2:
The patent applies segmentation by dividing the display operation into distinct phases: a first mode for normal operation with simplified standardized images, and a second mode for LCA execution with detailed actual vehicle representations. This segmentation allows each mode to be optimized for its specific purpose without compromising the other.

AI summary
A vehicle control device includes a processor installed at a vehicle configured to execute driving assistance control. The processor is configured to cause display of an other-vehicle image generated based on surrounding information including information related to at least one other-vehicle traveling in surroundings of the vehicle, at a display device provided at the vehicle. The other-vehicle image represents the other-vehicle with a same color as that of the other-vehicle.
