Autonomous Vehicle Recognition Result Presentation Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face difficulties in recognizing individuals getting out of stationary vehicles, especially when the person is hidden behind the vehicle body or door, and existing solutions do not effectively notify the person of being recognized by the autonomous vehicle.
Innovation Solution
A recognition result presentation apparatus that detects a person appearance area on the road and presents a recognition result to the individual using light, sound, or image projections, ensuring the person is notified that the autonomous moving body has recognized the area where they will appear, including the use of light radiators, sound outputters, and image capturers to convey this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light source unit directly radiates light downward from the sliding door to illuminate the road surface, then pedestrians and drivers can recognize the situation, but the autonomous vehicle cannot recognize that the person is getting out
Solution Approach 1:
The patent introduces a recognition target presentation apparatus that projects light patterns (such as arrows or shapes) onto the road surface as an intermediary signal. This intermediary visual cue bridges the gap between the person exiting the vehicle and the autonomous vehicle's detection system, enabling the autonomous vehicle to recognize the situation without requiring direct detection of the person themselves.
Solution Approach 2:
The patent utilizes changes in light color or pattern to convey different recognition states. The recognition target presentation apparatus projects specific colored light patterns onto the road surface to indicate the presence and movement of a person, allowing the autonomous vehicle to interpret these visual changes as recognition information.
2Loss of information
If the autonomous vehicle passes by a stationary vehicle without recognition, then the vehicle can maintain its speed, but the person getting out cannot determine whether they have been recognized
Solution Approach 1:
The patent implements a feedback mechanism where the recognition result presentation apparatus provides visual feedback to the person exiting the vehicle. By projecting light patterns that indicate recognition status, the system allows the person to confirm whether they have been detected by the autonomous vehicle, enabling informed decision-making about their movement.
Solution Approach 2:
The system performs preliminary recognition and presents the recognition target before the autonomous vehicle reaches the person. This allows the person to know in advance whether they have been recognized, enabling them to make timely decisions about whether to proceed into the autonomous vehicle's path.
3Measurement precision
If the recognition target presentation apparatus projects light patterns on the road, then the autonomous vehicle can recognize the person appearance area, but the person cannot be certain that the autonomous vehicle has recognized them
Solution Approach 1:
The patent employs feedback through the recognition result presentation apparatus that provides visual confirmation to the person. The apparatus projects specific light patterns that indicate not only that a person is detected but also confirm the recognition status, allowing the person to understand that the autonomous vehicle has successfully identified their presence.
Solution Approach 2:
The recognition result presentation apparatus acts as an intermediary communication channel between the autonomous vehicle's detection system and the person exiting the vehicle. It translates the vehicle's internal recognition data into visible light patterns that the person can interpret as confirmation of being recognized.
Data Source
AI summary
An apparatus and a method capable of accurately recognizing that a person will appear on a road and certainly notifying the person that an autonomous moving body has recognized a place where the person will appear are disclosed. An apparatus according to an embodiment of the present disclosure detects, as a recognition target, a person appearance area, in which a person will appear, formed by a recognition target presentation apparatus on a road and presents, to the person, a result of recognition indicating that the autonomous moving body has recognized the person appearance area as a result of the detection of the recognition target.
