Vehicle Top-View Display Switching Near a Target Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems, such as those displaying peripheral images, may be insufficient for providing information about the traveling situation when the vehicle is not moving at low speeds, as they do not allow users to check the situation ahead.
Innovation Solution
A control device that generates and displays top view images from different angles based on external sensor information, switching between a first top view image from the rear side and a second top view image from the vertical direction depending on the distance to the target position, to provide relevant situational information during travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a peripheral image is displayed on a display unit, then the user can check the surrounding situation of the vehicle, but the user cannot check the situation in the traveling direction when the vehicle is moving at normal speed
Solution Approach 1:
The patent applies dimensionality change by switching from a two-dimensional peripheral view to a three-dimensional top-view representation. The top-view image provides a bird's-eye perspective that simultaneously displays both the peripheral situation and the traveling direction situation, resolving the information loss without adding complex hardware by changing the visual dimension.
Solution Approach 2:
The patent implements dynamics by making the display content adaptive based on vehicle speed. The display unit dynamically switches between peripheral images and top-view images according to the vehicle's traveling state, providing appropriate information for each speed condition without requiring multiple fixed display systems.
2Loss of information
If a top view image is displayed to show the traveling direction situation, then the user can check the situation ahead, but the peripheral situation information may be insufficient
Solution Approach 1:
The patent uses dimensionality change to create a top-view representation that consolidates peripheral information into a comprehensive overhead perspective. This single view provides sufficient peripheral situation awareness without needing multiple separate displays, avoiding increased system complexity.
Solution Approach 2:
The patent applies dynamics by conditionally switching display content based on vehicle speed. When the vehicle moves slowly, the system displays top-view images that show peripheral situations; when moving fast, it switches to peripheral images. This dynamic adaptation ensures adequate peripheral information is provided only when necessary, avoiding unnecessary complexity.
3Loss of information
If the display unit shows a peripheral image, then the surrounding environment is visible, but the situation in the distance in the traveling direction is not included
Solution Approach 1:
The patent resolves this contradiction by transitioning to a three-dimensional top-view perspective that extends the visible range in the traveling direction. The overhead view naturally incorporates distant objects along the vehicle's path that would be outside the field of view of side-mounted cameras, providing distant situation information without adding complex wide-angle or multiple camera systems.
4Adaptability or versatility
If the display unit shows a top view image from the rear side, then the traveling direction situation is visible, but the display may not be appropriate when the vehicle is close to the target position
Solution Approach 1:
The patent applies dynamics by making the display system adaptive to the vehicle's operational context. The display control unit dynamically selects between top-view images and peripheral images based on real-time vehicle speed and proximity to target position, ensuring the displayed information is always appropriate for the current traveling situation without requiring manual intervention or complex configuration.
Solution Approach 2:
The patent implements feedback by using vehicle speed and position data to automatically adjust the display content. The system continuously monitors traveling conditions and provides feedback to the display control unit, which then selects the most appropriate view type, creating a closed-loop system that adapts to changing conditions without increasing operational complexity.

AI summary
A control device includes: an acquisition unit; an image processing unit configured to generate a first top view image in which a vehicle is viewed from sky and from a rear side with respect to a center of the vehicle in a traveling direction with a front side in the traveling direction included in an angle of view, and a second top view image in which the vehicle is viewed from the sky in a vertical direction; a control unit configured to control movement of the vehicle to a target position; and a display control unit. The display control unit is configured to cause a display unit to display the first top view image in response to a distance to the target position being equal to or greater than a predetermined value, and the second top view image in response to the distance being less than the predetermined value.
