Vehicle Hazard Display Filtering by Risk Level Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe driving support systems overwhelm drivers with excessive information in complex traffic scenarios, making it difficult to identify the most dangerous potential conflicts.
Innovation Solution
A safety confirmation support device equipped with hardware and software components, including moving object detection, risk level assessment, and targeted display control, which only displays information about detected objects with a risk level above a threshold, using multiple detection areas and display units strategically positioned around the vehicle to guide the driver's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all detected moving objects are displayed on the display unit, then the driver can be aware of all potential hazards, but the information becomes too complicated and causes driver confusion in complex traffic scenarios
Solution Approach 1:
The patent applies parameter changes by introducing a risk level parameter to filter and prioritize displayed information. The system calculates risk levels based on multiple factors (distance, relative speed, object type, detection area) and only displays objects exceeding a threshold, transforming the display from showing all objects to showing only high-risk objects.
Solution Approach 2:
The patent applies local quality by making different parts of the detection system have different functions. Each detection area (front, rear, left, right) is associated with specific display units, and the risk level threshold may vary by area. This allows the system to prioritize display of critical hazards in specific locations while reducing overall information complexity.
2Ease of operation
If risk level calculation and threshold filtering are implemented, then driver confusion is reduced by showing only critical hazards, but the system complexity and computational load increase
Solution Approach 1:
The patent applies segmentation by dividing the risk calculation into distinct modular components: detection unit, risk level calculation unit, threshold comparison unit, and display control unit. Each component performs a specific function, making the overall complex system manageable through functional segmentation and independent optimization.
Solution Approach 2:
The patent applies preliminary action by pre-calculating risk levels for all detected objects before display. The system performs risk assessment, threshold comparison, and filtering in advance, so that only pre-processed high-risk objects are sent to the display unit, reducing real-time processing burden on the display system.

AI summary
A safety confirmation support device (equipment system) according to the present disclosure contains hardware of storage unit and CPU processor and several sensing & display devices, and corresponding software including moving object detection unit, risk level detection unit, and output display control unit etc. The moving object detection unit is used to detect an object in a detection area around a vehicle. The risk level detection unit is used to determine, for each detected object, a risk level indicating a level of risk affecting the vehicle. The output display control unit is used to control output display information about the object via the one or more output devices when the risk level of the object is equal to or higher than a predetermined threshold value, and not to display the information about the object when the risk level is below the threshold value.
