Visual Assistance Display for Hidden Hazard Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle detection systems may fail to provide information about objects that are not directly detected by in-vehicle devices, particularly in congested and complex traffic situations, leading to potential hazards.
Innovation Solution
A visual assistance display apparatus that utilizes a detection unit to identify potential objects undetectable by in-vehicle devices, using a control unit to superimpose a display on a real surrounding image, and incorporates public detection devices like LiDARs installed on signal poles to acquire additional data, enabling the display of potential objects through markers or alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only in-vehicle detection tools are used to detect objects, then the device complexity is reduced, but the reliability of hazard detection deteriorates in congested and complex traffic situations
Solution Approach 1:
The patent combines in-vehicle detection tools with public detection devices (such as LiDAR installed on signal poles) to create a hybrid detection system. This merging allows the system to leverage both the real-time capabilities of in-vehicle sensors and the extended coverage of public infrastructure sensors, thereby improving hazard detection reliability without requiring a complete redesign of the detection architecture
Solution Approach 2:
The patent introduces a communication unit as an intermediary that facilitates data exchange between in-vehicle devices and public detection devices. This mediator enables the integration of detection data from external sources without requiring direct physical coupling, thus improving detection reliability while maintaining system modularity and avoiding excessive complexity
2Reliability
If public detection devices are integrated to detect additional objects, then the reliability of object detection is improved, but the device complexity increases
Solution Approach 1:
The patent designs the communication unit with multi-functionality, enabling it to handle various types of data exchange protocols and communication modes (direct communication, infrastructure-mediated communication). This universal design allows the system to integrate with different public detection devices without requiring separate communication infrastructure for each device type, thereby reducing integration complexity while maintaining high detection reliability
3Loss of information
If the display shows multiple potential objects with markers, then the information completeness for the driver is improved, but the ease of operation deteriorates due to information overload
Solution Approach 1:
The patent applies different visual characteristics (colors, marker types, display positions) to different potential objects based on their specific attributes such as distance, type, and urgency level. This local differentiation allows the driver to quickly distinguish between different categories of potential hazards without being overwhelmed by uniform information presentation, thus maintaining information completeness while improving ease of operation through enhanced information hierarchy

AI summary
A visual assistance display apparatus includes: a detection unit that detects an object; and a control unit that causes a display device to display a potential object that is undetectable by the detector in a manner that is superimposed on a real surrounding image. The control unit causes the display device to display an image that notifies the potential object in association with an object that obstructs a view of the potential object.
