Vehicle Safe Exit Assist Device with Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safe exit assist systems in vehicles only keep doors locked when a risk is detected, but this restricts back-seat passengers from operating windows, leading to user inconvenience and reduced child lock usage.
Innovation Solution
A device and method that determine and notify the passenger's intent to exit based on surrounding situations and vehicle conditions, providing step-by-step notifications, including primary and secondary alerts, to ensure safe exit without requiring the child lock mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the child lock is activated to prevent collision with approaching objects, then passenger safety is improved, but passenger convenience deteriorates because back-seat passengers cannot operate windows or open/close doors
Solution Approach 1:
The system performs preliminary detection of approaching objects and passenger exit intent before the actual exit occurs. When an object is detected approaching from the rear lateral side and the passenger shows exit intent (seatbelt unfastened, moving toward door), the system proactively notifies the passenger and controls the door lock state accordingly, preventing collision before it happens while maintaining operational freedom
Solution Approach 2:
The system continuously monitors passenger actions (seatbelt status, body movement toward door, hand approaching door handle) and provides real-time feedback through notifications. This feedback loop allows the system to adjust door lock control dynamically based on the passenger's actual intent, ensuring safety without unnecessarily restricting operation
2Reliability
If the door is kept locked when risk is detected, then collision prevention is improved, but passenger exit flexibility deteriorates
Solution Approach 1:
The door lock control is made dynamic rather than static. The system adjusts the door lock state in real-time based on the detected situation: when an approaching object is detected and exit intent is confirmed, the door is controlled to remain locked or provide locked control, but this control state is continuously adjusted based on ongoing detection of object distance and passenger actions, providing adaptive safety
3Reliability
If step-by-step notification is implemented based on passenger intent detection, then safety notification effectiveness is improved, but system complexity increases
Solution Approach 1:
The notification process is segmented into distinct stages based on detected passenger intent: primary notification when an approaching object is detected, and secondary notification when exit intent is confirmed (through seatbelt unfastening, movement toward door, or hand approaching door handle). This segmentation allows the system to provide appropriately timed and targeted notifications without requiring overly complex continuous control

AI summary
The present disclosure relates to a device for assisting a safe exit from a vehicle, a system having the same, and a method thereof. The device for assisting a safe exit from a vehicle may include a processor for determining a surrounding situation around the vehicle and an intent of the passenger to exit from the vehicle, and performing a step-by-step notification based on the determination, and storage for receiving, from the processor, and storing information about the surrounding situation and a determination result of the intent of the passenger to exit from the vehicle.
