Dynamic Contour Guide Line Adjustment for Vehicle Periphery Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle periphery display systems may lead occupants to misunderstand the distance to obstacles due to fixed contour guide lines, increasing the risk of collisions when objects appear to float above the road surface.
Innovation Solution
A vehicle periphery display device that acquires and processes images to display a stereoscopic view of the vehicle and its surroundings, dynamically adjusting the position of contour and predicted course guide lines to ensure they appear above the road surface when the vehicle turns, thereby enhancing the visibility of obstacles and reducing collision risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the contour guide line is displayed at a fixed position with respect to the vehicle image in the display image, then the display structure is simple and easy to implement, but the occupant may misunderstand the distance to obstacles and collision risk increases
Solution Approach 1:
The patent applies the dynamics principle by making the contour guide line movable rather than fixed. The guide line dynamically adjusts its position based on the vehicle's turning state, moving upward when the vehicle turns to prevent misinterpretation of obstacle distances. This resolves the contradiction by introducing adaptability that maintains simplicity while improving safety.
Solution Approach 2:
The patent changes the position parameter of the contour guide line based on vehicle turning conditions. When the vehicle turns, the guide line's vertical position is adjusted upward, creating a safety margin that prevents occupants from misjudging distances to obstacles. This parameter adjustment resolves the contradiction between simple display structure and accurate distance judgment.
2Reliability
If the contour guide line position is adjusted dynamically based on vehicle turning, then the distance judgment accuracy improves, but the control complexity increases
Solution Approach 1:
The system dynamically adjusts the contour guide line position based on real-time vehicle turning detection. The control mechanism monitors vehicle state and automatically modifies guide line display position, improving distance judgment accuracy without requiring complex manual intervention or overly sophisticated control systems.
Solution Approach 2:
The display system performs self-adjustment based on vehicle turning conditions. The control portion automatically detects vehicle state and modifies the guide line position without external input, making the system self-regulating and reducing the need for complex external control mechanisms while maintaining improved distance judgment.
3Measurement precision
If the contour guide line is displayed on the road surface level, then the display accurately represents the vehicle position, but obstacles appearing to float from the road surface create confusion
Solution Approach 1:
The patent introduces a vertical dimension adjustment to the contour guide line display. When the vehicle turns, the guide line is shifted upward from the road surface level, creating a visual separation that prevents obstacles from appearing to float. This dimensional adjustment maintains vehicle position accuracy while improving obstacle position clarity.
Solution Approach 2:
The patent applies local quality by making the guide line position conditional rather than uniform. The guide line displays at road surface level during straight driving but shifts upward during turning, creating different display qualities for different driving conditions. This resolves the contradiction by optimizing both vehicle position representation and obstacle clarity for specific operational contexts.

AI summary
A vehicle periphery display device includes: an acquisition portion acquiring a captured image obtained by imaging a periphery of a vehicle with an imaging portion; and a display processing portion causing a display image that is a stereoscopic image of the vehicle and the periphery of the vehicle to be displayed on a display portion on the basis of the captured image. The display processing portion causes at least one of a contour guide line representing a contour of the vehicle, and a predicted course guide line that is a trajectory drawn by the contour guide line according to movement of the vehicle to be included in the display image, and changes a position of at least one of the contour guide and predicted course guide lines such that the contour guide and predicted course guide lines are present above a road surface when the vehicle is turned.
