Vehicle Display Device Using Virtual Vehicle Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display devices do not effectively display the surrounding circumstances of a host vehicle in an intuitive and understandable manner, lacking the ability to dynamically reflect changes in the environment and vehicle status.
Innovation Solution
A vehicle display device that includes a display unit, an imaging unit, and a controller to generate a virtual vehicle image, where the captured surroundings are displayed as a reflected image on the virtual vehicle, allowing the orientation to adjust based on changes in the environment and vehicle status, and emphasizing specific objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a virtual vehicle image with reflected surroundings is displayed, then driver awareness and intuitiveness are improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual vehicle image that copies the actual vehicle's appearance and pastes captured surrounding images onto its surface as reflected images. This copying approach allows the system to present familiar visual information in an intuitive format without requiring complex real-time rendering of complete 3D environments, thereby improving driver awareness while controlling system complexity
Solution Approach 2:
The virtual vehicle image serves as an intermediary between the actual vehicle and the driver. Instead of directly displaying raw camera feeds or complex point-cloud data, the system uses this intermediate virtual representation to convey surrounding circumstances in a naturally understandable format, reducing the cognitive load on the driver while managing information processing requirements
2Loss of information
If the virtual vehicle orientation adjusts dynamically to changes in surroundings, then information accessibility is improved, but processing requirements increase
Solution Approach 1:
The virtual vehicle image's orientation is made dynamic, automatically adjusting to match the actual vehicle's orientation and the relevant direction of surrounding objects. This dynamic adaptation allows the display to maintain optimal information accessibility as the vehicle moves and the environment changes, without requiring complete re-rendering of the entire scene, thus balancing responsiveness with processing efficiency
3Measurement precision
If specific objects are emphasized in the reflected image, then recognition accuracy is improved, but image processing complexity increases
Solution Approach 1:
The patent applies local quality enhancement by emphasizing specific objects (such as pedestrians, vehicles, or obstacles) within the reflected images on the virtual vehicle surface. Rather than uniformly processing all visual information, the system selectively enhances regions containing important objects, improving recognition accuracy while avoiding the computational overhead of processing the entire image at high detail levels

AI summary
A vehicle display device includes: a display unit that is disposed in a host vehicle and that displays an image; an imaging unit that captures an image of circumstances surrounding the host vehicle; and a controller configured to perform processing through which, by controlling the display unit, a virtual vehicle image representing a virtual vehicle imitating the host vehicle is displayed, and the image of the circumstances surrounding the host vehicle captured by the imaging unit is pasted for display as a reflected image representing reflection in the host vehicle onto an outer panel of the virtual vehicle represented by the virtual vehicle image.
