AR Door Opening Warning for Vehicle Exit Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems fail to actively monitor the environment for hazards that may harm occupants exiting the vehicle, particularly rear seat passengers who lack exterior mirrors for situational awareness.
Innovation Solution
A system utilizing onboard sensors and a system controller to detect an occupant's intent to exit, analyze the environment for hazards, and provide augmented reality alerts on a vehicle display to warn of potential collisions or tripping hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current sensor systems and mirrors are used to monitor the environment, then the system structure is simple, but they fail to actively monitor for hazards that may harm occupants exiting the vehicle
Solution Approach 1:
The system integrates multiple functions into a unified architecture: the sensor system serves both traditional proximity warning and new exit hazard detection functions; the display system shows both standard traffic information and augmented reality hazard overlays; the controller processes both regular sensor data and occupant exit intent data. This multi-functionality improves reliability without proportionally increasing complexity.
Solution Approach 2:
The patent combines the occupant monitoring system with the existing sensor system and display system into an integrated hazard warning system. The controller merges data from sensors, occupant monitoring, and environmental cameras to generate unified augmented reality alerts, reducing overall system complexity while enhancing hazard detection capability.
2Object-affected harmful factors
If augmented reality alerts are provided to warn occupants of hazards, then occupant safety is improved, but the device complexity increases
Solution Approach 1:
The system introduces an intermediary processing layer that receives raw sensor data, occupant monitoring data, and camera feeds, then processes and synthesizes this information into simplified augmented reality alerts displayed on the screen. This intermediary layer manages complexity by abstracting the processing requirements while delivering simple, clear safety warnings to occupants.
Solution Approach 2:
The system performs preliminary detection and analysis of hazards before the occupant actually exits the vehicle. By detecting exit intent early and pre-processing hazard information, the system prepares augmented reality alerts in advance, reducing the computational burden during the critical exit moment and improving overall system efficiency.
3Measurement precision
If the system monitors occupant position and environment continuously, then hazard detection accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic detection triggered by specific events: when the occupant monitoring system detects exit intent, or when the door latch is actuated. This periodic action maintains high detection accuracy during critical moments while significantly reducing energy consumption during normal occupied periods.
Solution Approach 2:
The system performs preliminary monitoring of occupant position and prepares environmental data in advance, but only activates full hazard detection and augmented reality display when exit intent is detected. This preliminary preparation maintains accuracy readiness while minimizing continuous energy consumption of the full monitoring system.

AI summary
A system for providing warning to an occupant within a vehicle prior to the occupant exiting the vehicle includes a plurality of onboard sensors adapted to collect information related to an environment outside the vehicle, an occupant monitoring system adapted to monitor and detect movement of the occupant within the vehicle, a display screen adapted to be viewed by the occupant within the vehicle, a system controller adapted to detect when the occupant within the vehicle is about to exit the vehicle, detect a position of the occupant within the vehicle, display, on the display screen, a view of an environment outside of the vehicle, determine if there is a hazardous object within the environment outside of the vehicle, and classify the hazardous object, and provide augmented reality alerts within the display screen.
