Vehicle Risk Notification Control for Context-Aware Voice Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision warning systems in vehicles often cause driver confusion by providing unnecessary or unclear notifications when a passerby is not approaching the vehicle, leading to discomfort and difficulty in understanding the nature of the warning.
Innovation Solution
A control apparatus equipped with an image capturing device, processors, and a notification control unit that provides either direct or indirect voice notifications based on the proximity and recognition of potential collision risks, using natural language to inform the driver about the identified risk targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning sound is output when a passerby is approaching, then the driver can grasp the collision risk, but the driver cannot instantaneously understand what the warning is for without additional visual information
Solution Approach 1:
The system transitions from audio-only warning to combined audio-visual warning by displaying the captured image of the passerby on the windshield. This adds a visual dimension to the audio warning, enabling the driver to immediately identify the warning target (passerby) while maintaining effective collision alerting.
2Loss of information
If visual information is displayed on the windshield to notify of warning target, then the driver can understand the warning, but increased attention calling causes discomfort or confusion
Solution Approach 1:
The system applies different notification intensities to different situations: visual information is displayed only when a passerby is detected, while general warnings use audio only. This localized application of visual attention calling reduces overall driver discomfort and confusion while maintaining effective warning target identification when necessary.
Solution Approach 2:
The notification system dynamically adjusts its behavior based on the detected situation. Visual display is activated conditionally only when a passerby is identified, creating a dynamic response that prevents unnecessary visual interruptions and reduces driver discomfort while maintaining effective warning communication.
3Device complexity
If only audio warning is used, then the system remains simple, but the driver cannot grasp the specific target of the warning
Solution Approach 1:
The image capturing device and display system act as intermediaries between the detection system and the driver. Instead of directly presenting complex data, the system captures and displays the actual image of the passerby, providing intuitive target identification while maintaining relative system simplicity through existing automotive components.

AI summary
A control apparatus disposed in a moving body including an image capturing device acquires an image of an outside of the moving body captured by the image capturing device, and recognizes an object outside the moving body on the basis of the image. The apparatus identifies a risk target having a risk of coming into proximity with the moving body among the recognized objects, and gives a user a voice notification using a natural language including an expression representing a recognized object. The apparatus gives the user either a direct notification for notifying the user of the presence of a risk posed by the risk target or an indirect notification for notifying the user of information suggesting the risk target, on the basis of the risk target and a traveling state of the moving body.
