Adaptive Light Source for Safe Vehicle Exit Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe exiting systems for vehicles often fail to effectively alert passengers of potential dangers when exiting, particularly in noisy environments and do not provide direct visual warnings, which can lead to accidents, especially for vulnerable groups like the elderly and children.
Innovation Solution
A safe exiting assistance system that includes an object detector, a body detector, a door opening/closing detector, a determiner, and a controller to provide a visual warning by adjusting the position and irradiation angle of a light source based on the passenger's physical information and the risk level of approaching objects, ensuring the alert is displayed at an optimal position for the passenger's eye height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a cluster pop-up arrangement is used to warn of danger, then the driver can be notified, but the warning is not delivered directly to the passenger actually exiting
Solution Approach 1:
The warning system is segmented to provide different types of alerts for different scenarios: cluster pop-up for driver notification and direct visual warning (light source) for passenger notification. This segmentation ensures that each user receives appropriate warning information tailored to their position and needs.
Solution Approach 2:
A light source is introduced as an intermediary device to directly communicate danger information to the exiting passenger. This intermediary bridges the gap between the detection system and the passenger, providing direct visual warning that cannot be missed during the exit process.
2Loss of information
If a typical warning sound is used, then the driver can be alerted, but the passenger may not hear the sound alert in a noisy environment
Solution Approach 1:
The acoustic warning system is replaced with an optical warning system (light source). This substitution eliminates the vulnerability to noise interference that plagues acoustic warnings, as visual signals are not affected by auditory environment conditions.
Solution Approach 2:
The warning modality is changed from acoustic to optical parameters. By changing the physical parameter of the warning signal from sound waves to light, the system overcomes the limitation of noise interference while maintaining effective warning transmission.
3Ease of operation
If a fixed position light source is used, then the structure is simple, but the alert may not be visible to passengers of different heights
Solution Approach 1:
The light source positioning system is made dynamic rather than fixed. The controller adjusts the position and irradiation angle of the light source based on real-time detection of passenger physical information, ensuring the alert is always visible regardless of passenger height or position.
Solution Approach 2:
The system incorporates feedback through the body detector that continuously monitors passenger physical information. This feedback loop enables the controller to automatically adjust the light source positioning to match the passenger's eye level, ensuring optimal visibility without manual intervention.
4Adaptability or versatility
If the light source position is fixed, then the device is simple, but the alert cannot be tailored to individual passenger characteristics
Solution Approach 1:
The system changes the positioning parameters of the light source based on detected passenger characteristics. By dynamically adjusting position and angle parameters according to passenger height, age, and seating position, the system achieves personalized alert delivery while maintaining operational simplicity through automated control.

AI summary
A safe exiting assistance system includes an object detector that detects an object which approaches from a rear side of a vehicle, a body detector that detects physical information of a passenger in the vehicle, a door opening/closing detector that detects door opening or closing information of the vehicle, a determiner that determines whether a situation requires alert to the passenger in response to detection results of the object detector and the door opening/closing detector and calculates a value sensed by the body detector in response to vehicle information set in advance, and a controller that differently controls a position and an irradiation angle of a light source in response to the physical information when information in which the alert is necessary is received from the determiner.
