Vehicle Stop Guide Display for Bumper Overlap Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems struggle to accurately depict the distance to a stopping position due to overlapping of vehicle bumpers and stop guides, making it difficult for drivers to gauge the correct stopping distance, especially when using cameras with different attachment positions and angles.
Innovation Solution
A control device and method that adjusts the display mode of stop guides based on overlap with specific vehicle portions, such as the bumper, by hiding or increasing transparency of overlapping regions to maintain visibility and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the stop guide is superimposed on the external environment recognition image in a conventional manner, then the stop guide can be displayed to indicate the stopping position, but when the stop guide overlaps with the vehicle bumper in the image, it creates visual confusion that makes it difficult for the driver to accurately grasp the distance to the stopping position
Solution Approach 1:
The patent applies local quality by making different parts of the stop guide have different display characteristics. Specifically, when the stop guide overlaps with the vehicle bumper in the external environment recognition image, the display control unit changes the display mode of the overlapping portion (e.g., making it transparent or hiding it) while maintaining the normal display of non-overlapping portions. This localized adjustment resolves the visual confusion caused by overlap while preserving the overall functionality of the stop guide display.
2Measurement precision
If the front camera attachment position and angle are adjusted to include the vehicle bumper in the surrounding image, then the driver can better grasp distance relationships, but the stop guide and bumper may overlap in the displayed image, creating visual confusion
Solution Approach 1:
The patent applies dynamics by making the display mode of the stop guide dynamically adjustable based on its spatial relationship with the vehicle bumper. The display control unit continuously monitors whether the stop guide overlaps with the bumper in the external environment recognition image and automatically adjusts the display mode of the overlapping portion accordingly. This dynamic adjustment ensures that the display adapts to different parking scenarios while maintaining clear distance information for the driver.

AI summary
A control device includes: an external environment recognition unit configured to acquire an external environment recognition image showing a recognition result of surroundings of a moving body; and a display control unit configured to display the external environment recognition image on a display device. The display control unit is configured to superimpose and display a stop guide indicating a position where movement of the moving body needs to be stopped on the external environment recognition image on the display device, and, when the stop guide is superimposed on the external environment recognition image, the display control unit makes a display mode of the stop guide different according to whether a specific portion of the moving body included in the external environment recognition image and the stop guide overlap with each other.
