Vehicle Notifying Device Predicts Driver Abnormality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices fail to provide notifications when a driver is predicted to fall into an abnormal state in communication impossible areas, as communication with external devices is not feasible.
Innovation Solution
A notifying device that acquires vehicle position and map information, predicts road paths, detects driver abnormalities, and anticipates communication impossible areas to send notifications to external devices when the vehicle exits these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver abnormality detection function is implemented, then the driver safety is improved, but the notification capability deteriorates in communication impossible areas
Solution Approach 1:
The system performs preliminary actions by detecting driver abnormality indicators before the driver fully loses driving ability, and by predicting the future position where the abnormality will occur. This allows the system to prepare and send notifications at the predicted position even if the current position is in a communication impossible area, thereby maintaining notification capability while ensuring driver safety.
2Loss of energy
If notification is sent only when communication is possible, then communication resources are saved, but driver safety is compromised in communication impossible areas
Solution Approach 1:
The system performs preliminary detection of driver abnormality indicators and predicts the position where the abnormality will occur before communication is needed. By preparing the notification in advance at the predicted position, the system can send notifications efficiently only when communication is available, saving communication resources while ensuring driver safety is not compromised.
3Loss of time
If the system predicts driver abnormality and sends immediate notification, then response time is improved, but notification accuracy deteriorates when current position is in communication impossible area
Solution Approach 1:
The system performs preliminary detection of driver abnormality indicators and predicts the future position where the abnormality will occur. By sending notifications at the predicted position rather than the current position, the system maintains both rapid response time and high notification accuracy, even when the current position is in a communication impossible area.
Solution Approach 2:
The system introduces an intermediary element - the predicted position - as a mediator between the current detection position and the notification sending position. This intermediary allows the system to bridge the gap between immediate detection and reliable communication, maintaining both response time and notification accuracy.

AI summary
A notifying device predicts the position of a vehicle, on a road through which the vehicle is predicted to pass, after a lapse of the time taken for the driver to fall into an abnormal state. When the predicted position of the vehicle is included in a communication impossible area, the notifying device notifies, at the position of a point where an indication that the driver is going to fall into the abnormal state is detected, a call center terminal that the indication that the driver is going to fall into the abnormal state is detected from the driver.
