Vehicle Hazard Notification Control for Off-Board Passengers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to notify an off-board passenger of hazardous situations occurring around a vehicle when an on-board passenger is present, leading to anxiety for the off-board passenger regarding the safety of the on-board passenger.
Innovation Solution
A notification controller that includes an on-board passenger judgment unit, a hazard judgment unit, and a notification control unit. This system determines if there is an on-board passenger and if a hazardous situation is occurring around the vehicle, and then makes radio communication with the off-board passenger's communication terminal to notify them of the hazardous situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional notification systems are used, then notification simplicity is maintained, but notification completeness deteriorates (off-board passengers cannot be notified of hazards when on-board passengers remain in the vehicle)
Solution Approach 1:
The notification system dynamically adapts its behavior based on real-time detection of passenger presence. The control unit determines whether to send notifications by evaluating current vehicle occupancy status, transitioning the system from a static notification approach to a dynamic one that responds to changing conditions. This resolves the contradiction by making the notification system intelligent and adaptive without requiring complete system redesign.
Solution Approach 2:
The system incorporates feedback mechanisms through passenger detection units that continuously monitor vehicle occupancy. This feedback loop enables the control unit to make informed decisions about notification delivery, ensuring that off-board passengers are notified only when appropriate (when on-board passengers are present). The feedback mechanism eliminates information loss while maintaining reasonable system complexity through targeted, condition-based notifications.
2Reliability
If notification is sent to off-board passengers, then passenger safety awareness is improved, but false alarm rate increases (anxiety caused by unnecessary notifications)
Solution Approach 1:
The notification system applies local quality by differentiating notification behavior based on specific vehicle occupancy conditions. Rather than uniformly notifying all off-board passengers in all situations, the system selectively notifies only when on-board passengers are detected. This localized approach to notification improves reliability by ensuring notifications are contextually appropriate while reducing harmful effects like unnecessary anxiety from false alarms.
Solution Approach 2:
The system performs preliminary detection of passenger presence before issuing notifications. The passenger detection units continuously monitor and prepare data about vehicle occupancy in advance, enabling the control unit to make accurate real-time decisions. This preliminary action ensures that notifications are sent only when warranted by actual conditions, improving reliability while preventing premature or false notifications that would cause unnecessary anxiety.
3Measurement precision
If continuous monitoring of vehicle surroundings is implemented, then hazard detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring rather than continuous monitoring, using passenger detection units that operate at intervals or triggered by specific events. This periodic action maintains adequate hazard detection accuracy for safety purposes while significantly reducing energy consumption compared to constant monitoring. The balance between measurement precision and energy use is achieved through time-based optimization of the monitoring cycle.
Solution Approach 2:
The notification system leverages existing vehicle sensors and detection units that are already part of the vehicle's infrastructure, making them serve dual purposes: their original function plus hazard detection for notification purposes. This self-service approach allows the system to achieve improved measurement precision without adding significant energy consumption, as existing components are utilized efficiently for multiple functions.

AI summary
The present disclosure is intended to notify an off-board passenger of a hazardous situation occurring around a target vehicle in the presence of an on-board passenger in the vehicle. A notification controller according to the present disclosure includes: an on-board passenger judgment unit, if at least one passenger in a target vehicle gets out of the vehicle to become an off-board passenger, the on-board passenger judgment unit judging whether there is a different passenger staying in the target vehicle; a hazard judgment unit that judges whether a hazardous situation is occurring around the target vehicle if there is an on-board passenger; and a notification control unit that makes radio communication with a communication terminal of the off-board passenger to make outward notification that is notification indicating the occurrence of the hazardous situation to the off-board passenger if the hazard judgment unit judges that the hazardous situation is occurring.
