Vehicle Child Lock Latch Dynamic Control via Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child lock systems do not effectively assist passengers in safely exiting a vehicle, particularly in situations where a collision is imminent or a blind spot detection warning is triggered, potentially preventing safe egress.
Innovation Solution
A safety exit assist system that integrates child lock latches and a controller to execute child lock or release functions based on proximity warning signals from a blind spot detection device, ensuring passengers can safely exit the vehicle by controlling the child lock latches in response to collision or proximity warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the child lock is always engaged to prevent children from opening doors, then child safety is improved, but passengers cannot exit safely during emergencies or when collision warnings are detected
Solution Approach 1:
The child lock system dynamically adjusts its state based on real-time conditions. The controller receives collision warning signals from the BSD device and automatically engages or disengages the child lock accordingly, transforming the static lock into a dynamic safety system that adapts to changing environmental conditions
Solution Approach 2:
The system implements feedback control by continuously monitoring collision warning signals from the BSD device and adjusting the child lock state based on this feedback. When a collision warning is detected, the system responds by disengaging the lock to allow safe egress, and when no warning is present, it maintains the locked state for child protection
2Reliability
If the child lock is frequently engaged and disengaged in response to proximity warnings, then passenger safety is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary assessment by evaluating the collision warning signal before executing the lock state change. Only when a valid collision warning is detected does the system disengage the lock, avoiding unnecessary state changes and reducing power consumption while maintaining safety
Solution Approach 2:
The system changes the operational parameters of the child lock based on detected conditions. The lock state transitions between engaged and disengaged only when necessary, controlled by the controller based on BSD device warnings, optimizing the balance between safety and energy consumption
3Device complexity
If the child lock system operates independently without integration with safety devices, then system simplicity is maintained, but the ability to assist safe exit during collisions is reduced
Solution Approach 1:
The child lock system is merged with the BSD device to create an integrated safety system. The controller of the child lock system communicates with the BSD device, combining two previously separate functions into a unified system that provides both child protection and collision-responsive egress assistance
Solution Approach 2:
The integrated system performs multiple functions: it provides child protection by preventing door opening from the inside, and simultaneously provides collision emergency egress assistance by automatically disengaging the lock when collision warnings are detected, making the system universally applicable to both safety scenarios

AI summary
A safety exit assist system and a method therefor are provided. The system includes a plurality of child lock latches configured to be respectively located in left and right doors of a vehicle and execute child lock or child lock release and a controller configured to control the plurality of child lock latches and instruct the plurality of child lock latches to execute the child lock if receiving a proximity warning signal relative to a rear of the vehicle from a blind spot detection (BSD) device.
