Vehicle Display Layout for Turn-Aligned Traffic Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems fail to effectively convey the traffic environment surrounding a vehicle to the driver in a manner that aligns with the actual driving scene, particularly when the vehicle is turning, leading to a disconnect between the displayed image and the driver's line of sight.
Innovation Solution
A display system that generates a composite image by overlaying real-time video images of traffic participants onto a virtual environment image, adjusting the display based on whether the vehicle is turning or not, and dynamically changing the display position to align with the driver's line of sight, using a display device with horizontally-oriented panels and additional panels near pillars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-point video image (from above vehicle or virtual mirror) is displayed, then the display system provides a stable overview of the surrounding environment, but the displayed image becomes much different from the actual scene that aligns with the driver's dynamic line of sight during turning maneuvers
Solution Approach 1:
The patent applies dynamics by making the virtual camera position and display content change dynamically based on the vehicle's turning state. When the vehicle turns, the virtual camera position is adjusted to follow the driver's line of sight, and the display switches between front and lateral views. This dynamic adaptation resolves the contradiction between providing a stable overview and adapting to the driver's changing perspective during turns.
Solution Approach 2:
The patent changes key parameters including the virtual camera position, display content type (front view vs. lateral view), and display position on the screen based on the vehicle's turning angle and driver's line of sight. These parameter changes allow the system to maintain accuracy of traffic environment representation while adapting to different driving scenarios and the driver's perspective.
2Device complexity
If the display system uses a fixed display position for the composite image, then the display layout is simple and stable, but the display does not align with the driver's line of sight when the vehicle is turning
Solution Approach 1:
The display position of the composite image is made dynamic rather than fixed. The system adjusts the display position based on the vehicle's turning state and the driver's line of sight, moving the image to the appropriate location on the display screen. This dynamic adjustment maintains ease of operation by keeping information in the driver's field of view while managing display layout complexity through automated control.
Solution Approach 2:
The patent introduces a control unit as an intermediary that processes information about the vehicle's turning state and driver's line of sight, then automatically adjusts the display position accordingly. This intermediary manages the complexity of coordinating multiple parameters while simplifying the driver's interaction by making the system self-adjusting.
3Loss of information
If the display system displays a comprehensive virtual environment image covering all directions, then the driver receives complete information about the surrounding traffic environment, but the driver must move their head to view different directions, reducing recognition efficiency
Solution Approach 1:
The patent applies local quality by displaying different types of information in different locations on the display screen. The front view displays the primary driving path and forward traffic environment, while the lateral view displays side areas and blind spots. This localized information placement allows the driver to view comprehensive traffic environment information without head movement, as all relevant information is presented in the driver's forward field of view.
Solution Approach 2:
The patent transitions from a single fixed perspective to a multi-dimensional display approach by switching between front and lateral views based on the vehicle's turning state. This dimensional change allows the system to present comprehensive traffic environment information in a way that aligns with the driver's natural line of sight, eliminating the need for head movement while maintaining information completeness.

AI summary
A display system includes a processor that acquires a current location of an own vehicle, generates a virtual environment image showing a surrounding environment of the own vehicle based on a current location of the own vehicle and map information, extracts a participant video image, the participant video image being a video image portion of a traffic participant from the real environment video image, determines the presence of an intention to turn of a driver of the own vehicle, and generates and displays on a display device a composite image by inlaying the participant video image into the virtual environment image at a corresponding position.
