Vehicle Left-Behind Detection With Stepwise Life-Prolongation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for preventing infants or children from being left behind in vehicles are inadequate, as they may not ensure accurate notification to drivers, impose a significant social burden on emergency services, and rely on battery power that may not sustain comfortable interior conditions for extended periods.
Innovation Solution
A vehicle system that includes a left-behind detection mechanism and a life prolongation control system to activate multiple safety measures sequentially based on elapsed time, such as notifications, air conditioner operation, window opening, and emergency service alerts, ensuring gradual and efficient life prolongation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification is provided to the driver or emergency services upon detection of leaving-behind, then the driver or emergency services can respond to the situation, but the driver may not notice the notification or emergency services must frequently dispatch which creates a significant social burden
Solution Approach 1:
The air conditioner is activated in advance upon detection of leaving-behind to improve the vehicle interior environment before the child's condition deteriorates. This preliminary action addresses the root cause (uncomfortable interior environment) while buying time for the driver to notice the notification or for emergency services to respond.
Solution Approach 2:
The safety system is segmented into multiple independent components: left-behind detection, notification system, and air conditioner activation. This segmentation allows the system to provide multiple functions (detection, alerting, and environmental control) without requiring a single complex emergency response mechanism, thereby reducing the burden on emergency services while maintaining reliability.
2Reliability
If an air conditioner is activated to improve the vehicle interior environment upon detection of leaving-behind, then the safety of an infant or child can be improved, but the operation time of the air conditioner is limited by remaining battery power or gasoline and cannot maintain comfortable interior environment for a long period
Solution Approach 1:
The air conditioner is activated as soon as leaving-behind is detected, before the interior environment becomes dangerously hot. This preliminary action maximizes the beneficial operating time of the air conditioner by starting cooling immediately, thereby extending the duration during which the child remains safe even though battery power or gasoline is limited.

AI summary
The vehicle of the present disclosure includes a left-behind detection section that detects whether or not a person is left behind in a vehicle, and a life prolongation control section that, when the left-behind detection section detects that the person is left behind, causes a plurality of life-prolongation-related sections of the vehicle to be activated stepwise according to an elapsed time after the person is left behind.
