Pedestrian Video Alerts for Automated Driving Blind Spots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated driving vehicles lack sufficient safety measures as operators are not presented with videos of pedestrians, particularly in blind spots, compromising operational safety.
Innovation Solution
A driving assistance apparatus that acquires video of a sidewalk bordering the roadway using a camera and, upon detecting a pedestrian, notifies an operator's terminal apparatus that the video is available for display, allowing the operator to view it upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving vehicles operate without presenting pedestrian videos to operators, then the system operates autonomously with high automation level, but safety in operation is insufficient
Solution Approach 1:
A driving assistance apparatus acts as an intermediary between the automated driving system and the operator. It receives video from cameras, detects pedestrians using image recognition, and selectively presents video to the operator's terminal when pedestrians are detected. This mediator approach maintains high automation while improving safety by providing targeted information to the operator.
Solution Approach 2:
The system performs preliminary pedestrian detection and video acquisition before the operator needs the information. The driving assistance apparatus continuously monitors video feeds and prepares pedestrian video for presentation, so that when an operator requests video or when a pedestrian is detected, the information is immediately available, reducing response time and improving safety.
2Reliability
If video of pedestrians is continuously presented to operators, then safety monitoring is improved, but device complexity and information overload increase
Solution Approach 1:
Instead of continuously presenting all video feeds to the operator, the system applies local quality by selectively presenting video based on specific conditions. The driving assistance apparatus analyzes video content and only presents footage when pedestrians are detected or when the operator initiates a request. This targeted approach improves safety monitoring while avoiding information overload and reducing unnecessary system complexity.
Solution Approach 2:
The system uses partial action by providing video information only when necessary rather than continuously. The driving assistance apparatus detects pedestrians and presents video selectively, rather than transmitting all video data at all times. This partial information provision achieves adequate safety monitoring without overwhelming the operator or requiring excessive system resources.
3Loss of information
If video is made available for display upon pedestrian detection, then operator awareness of hazards is improved, but response time and processing delay increase
Solution Approach 1:
The driving assistance apparatus performs preliminary pedestrian detection and video acquisition before the operator needs the information. The system continuously monitors video feeds and pre-processes footage, so when a pedestrian is detected or the operator requests video, the information is immediately ready for presentation. This preliminary preparation minimizes response time and ensures the operator receives hazard information without significant delay.
Data Source
AI summary
A driving assistance apparatus includes a controller that is configured to acquire video obtained by imaging, with a camera, a sidewalk along which a pedestrian passes, the sidewalk bordering on a roadway on which an automated driving vehicle travels, and upon detecting the pedestrian in the acquired video, cause a terminal apparatus of an operator of the automated driving vehicle to output a notification that the video is available for display.
