Dynamic Vehicle Periphery Display Guide Line Margin Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle periphery display systems are prone to displaying contour guide lines and predicted course guide lines at fixed positions, which can lead to vehicles passing excessively separated from objects during turns, especially when margins are included, causing potential collisions.
Innovation Solution
A vehicle periphery display device that acquires images of the vehicle's surroundings and dynamically adjusts the margins of contour and predicted course guide lines based on the vehicle's turning angle, ensuring these lines are displayed closer to the vehicle's contour or predicted path, thereby preventing excessive separation from objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the contour guide line is displayed at a fixed position with respect to the vehicle image, then the display is simple and stable, but the vehicle may pass through a position excessively separated from an object present therearound when the vehicle is turned
Solution Approach 1:
The patent applies the dynamics principle by making the contour guide line and predicted course guide line movable rather than fixed. The guide lines dynamically adjust their position and margin based on the vehicle's turning angle, transitioning from a static display to a dynamic one that adapts to changing vehicle states, thereby resolving the contradiction between display stability and positioning accuracy
Solution Approach 2:
The patent implements parameter changes by modifying the margin of the contour guide line according to the vehicle's turning angle. When the vehicle turns, the system changes the margin parameter to reduce the distance between the guide line and the vehicle contour, ensuring accurate positioning information is provided to the driver during turning maneuvers
2Reliability
If the contour guide line includes a margin, then the display provides a safety buffer, but the vehicle may pass through a position excessively separated from an object present therearound when the vehicle is turned
Solution Approach 1:
The system dynamically adjusts the margin of the contour guide line based on the vehicle's turning angle. During straight driving, a larger margin is maintained for safety, but during turns, the margin is reduced to improve positioning precision, thus resolving the contradiction between safety buffer and positioning precision through dynamic adaptation
Solution Approach 2:
The patent changes the margin parameter of the contour guide line according to the vehicle's turning angle. The system adjusts this parameter in real-time: maintaining a larger margin during straight driving for safety, and reducing the margin during turns to enhance positioning precision, thereby resolving the contradiction between safety buffer and positioning precision

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 including a vehicle image and a periphery image 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 image and having a first margin in a vehicle width direction of the vehicle image and a second margin in an advancing direction of the vehicle image, and a predicted course guide line that is a trajectory drawn by the contour guide line according to movement of the vehicle to be displayed in the display image, and changes at least one of the first and second margins when the vehicle is turned.
