In-Cabin Object Sensing for Injury Severity Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive systems fail to effectively detect and alert occupants of potentially injurious positions or obstructions within vehicles, which can lead to increased injury risk during impact events.
Innovation Solution
A system utilizing interior and exterior sensors, including cameras, RADAR, LiDAR, and ultrasonic devices, to determine the location, orientation, and type of objects within the vehicle, assessing if they are in alertworthy dispositions that pose a risk of injury, and providing visual or auditory alerts and corrective suggestions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (cameras, RADAR, LiDAR, ultrasonic devices) are deployed to detect object characteristics and injury risk, then measurement precision and reliability of injury prediction are improved, but device complexity and cost increase
Solution Approach 1:
The system divides the detection task into multiple specialized sensor modules, each responsible for specific characteristics (cameras for visual identification, RADAR for distance and velocity, LiDAR for 3D positioning, ultrasonic for proximity). This segmentation allows each sensor type to optimize for its specific function while collectively achieving comprehensive object characterization and injury risk assessment.
Solution Approach 2:
The sensor system is designed to perform multiple functions simultaneously - detecting object location, orientation, size, type, and movement characteristics all through the same sensor array. The processed data serves dual purposes: real-time injury severity prediction and generation of alert messages for occupant safety, maximizing the utility of the complex sensor infrastructure.
2Reliability
If real-time monitoring and alert systems are implemented to warn occupants of hazardous positions, then occupant safety is improved, but ease of operation is reduced due to additional alerts and system management
Solution Approach 1:
The system continuously monitors occupant position and object characteristics in advance of potential impact events, calculating injury severity predictions before collisions occur. Alert messages are generated proactively when hazardous conditions are detected, allowing occupants to correct their positions before an accident happens, rather than reacting after the fact.
Solution Approach 2:
The system provides real-time feedback to occupants through alert messages that communicate detected hazardous conditions and recommended corrective actions. This feedback loop allows occupants to understand the system's concerns and take appropriate actions to improve their safety, transforming the complex monitoring system into an intuitive safety assistant.

AI summary
A system for detecting one or more characteristics of an object within an automotive vehicle includes one or more sensors mounted within an interior of the vehicle or on an exterior of the vehicle, with each sensor being configured to detect a location, an orientation, a size and/or an object type of the object, and a controller operably connected with the one or more sensors and configured to assess whether the object is disposed in a predetermined alertworthy disposition. A method for detecting characteristics of the object within the vehicle includes determining the location, orientation, size and/or object type of the object using the one or more sensors, and assessing whether the object is disposed in a predetermined alertworthy disposition.
