Vehicle Emergency Notification Control With Occupant-Triggered Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems may report dangerous driving situations to third parties without occupant awareness, necessitating unnecessary conversations and potentially distracting the driver.
Innovation Solution
A notification device that allows occupants to selectively notify third parties of vehicle information and surroundings only when desired, omitting the need for driver interaction, and includes features to prevent notifications under certain conditions and provide safety measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving assistance control device automatically reports dangerous driving situations to third parties, then safety monitoring is improved, but driver distraction and unnecessary conversations increase
Solution Approach 1:
The system allows the driver to autonomously initiate notifications by operating a notification button, eliminating the need for automatic reporting that would require driver attention. The driver self-services the safety monitoring function by manually triggering notifications when they perceive dangerous situations, thus improving reliability without causing distraction.
Solution Approach 2:
The notification button serves as an intermediary between the driver and the third-party reporting system. Instead of direct automatic reporting that requires driver engagement, the button mediates by allowing silent, one-button initiation of notifications, resolving the contradiction between reliable safety monitoring and driver distraction.
2Productivity
If the system transmits only report information to third parties, then communication efficiency is improved, but the occupant must hold conversations to check current situations
Solution Approach 1:
The system performs preliminary actions by automatically capturing and transmitting comprehensive situation data (images, audio, position, vehicle state) along with the notification, eliminating the need for subsequent conversational exchanges. This preliminary transmission of all relevant information resolves the contradiction by maintaining communication efficiency while preventing time loss from necessary conversations.
Solution Approach 2:
The notification system segments information transmission into comprehensive packages containing multiple data types (images, audio, position, vehicle state) rather than simple text reports. This segmentation approach allows all necessary information to be transmitted in one action, improving productivity while eliminating the need for follow-up conversations that would consume time.
3Reliability
If the system notifies third parties of all abnormality notifications, then safety response is improved, but false notifications increase when no actual danger exists
Solution Approach 1:
The system incorporates feedback mechanisms by analyzing multiple data sources (inter-vehicle distance, surrounding images, audio) before generating notifications. This multi-factor feedback approach filters out false notifications caused by minor fluctuations in single parameters, resolving the contradiction between reliable safety response and reduction of false alarms.
Solution Approach 2:
The system changes the parameters used for notification determination from simple distance thresholds to a composite assessment including image analysis, audio detection, and contextual vehicle state information. This parameter transformation reduces false notifications while maintaining reliable safety response by considering multiple dimensions of actual danger.

AI summary
A notification device, comprising a processor, wherein the processor is configured to receive an abnormality notification from an occupant of a vehicle, and in a case in which the abnormality notification has been received, notify a third party of vehicle information including position information of the vehicle and an image of surroundings of the vehicle, which are stored at the vehicle, and notify the third party that the vehicle is in an abnormal situation.
