Surrounding Risk Display Apparatus Clearance Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surrounding risk displaying apparatuses do not effectively convey the risk of passing through a clearance between multiple risk objects, as they rely solely on physical possibility without considering high risk potentials due to proximity and relative motion.
Innovation Solution
A surrounding risk displaying apparatus that includes an environment recognizer, a surrounding risk recognizer, and a display unit capable of estimating risk potentials and displaying contour lines indicating the distribution of risk, with a passage risk display activated when the risk approaching determination value exceeds a threshold, forming a wall-shaped display to visually represent the risk of passing through the clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display shows only physical possibility of passing through clearance, then the device complexity is low, but the reliability of risk assessment is insufficient
Solution Approach 1:
The risk display is segmented into multiple components: individual risk object displays, clearance passage risk display, and contour line representations. Each segment conveys specific risk information, allowing the system to provide comprehensive risk assessment without overwhelming complexity.
Solution Approach 2:
The patent adds a new dimension of risk information by displaying passage risk through contour lines that connect equal risk potential points. This transforms the risk display from simple object detection to a multi-dimensional risk field visualization, improving assessment accuracy.
2Loss of information
If the display adds passage risk information, then the information completeness improves, but the ease of operation decreases
Solution Approach 1:
The display applies different visual qualities to different regions: individual risk objects are shown with their own characteristics, while the clearance passage risk is shown with contour lines indicating equal risk potential. This localized differentiation helps drivers quickly identify and process critical risk information.
Solution Approach 2:
The patent uses visual intensity and color variations in the contour line display to represent different levels of risk potential. This allows drivers to intuitively grasp risk magnitude without requiring complex numerical data, maintaining ease of operation while improving information completeness.

AI summary
A surrounding risk displaying apparatus includes an environment recognizer, a surrounding risk recognizer, and a display. The environment recognizer is capable of recognizing an environment around a vehicle. The surrounding risk recognizer is capable of extracting risk objects each having a risk potential not less than a predetermined risk potential, estimating a distribution of the risk potential around each of the risk objects, and calculating a risk approaching determination value that increases depending on relative approaching of the risk objects. The display is capable of displaying images in a superimposed fashion on the corresponding risk objects. The images each indicate the distribution of the risk potential around corresponding one of the risk objects. The display is capable of displaying, when the risk approaching determination value is not less than a predetermined threshold, a passage risk display indicating that passing through, by the vehicle, a clearance between the risk objects involves a risk.
