Vehicle Door Handle Control for Post-Collision Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to effectively manage the state of door handles during accidents, especially when the battery is compromised, making it difficult to rescue passengers.
Innovation Solution
A vehicle control apparatus that includes a processor, forward detection device, door handle driving device, and collision detection device to manage the state of door handles based on distance, speed, and collision detection, ensuring the door handle remains accessible even after a collision or battery failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the door handle is pushed in the door part during vehicle operation, then the aesthetic appearance is maintained, but the door handle becomes inaccessible for passenger rescue in case of accident
Solution Approach 1:
The door handle is designed to dynamically change its position between pushed-in and pulled-out states based on vehicle operating conditions. The control apparatus automatically transitions the door handle from pushed-in to pulled-out state when collision is detected, resolving the contradiction between aesthetic appearance during normal operation and accessibility during emergency situations.
2Extent of automation
If the door handle is controlled by the vehicle control apparatus during normal operation, then the door handle state can be managed, but the control system may fail when the battery is destroyed by fire or collision
Solution Approach 1:
The control apparatus pulls out the door handle in advance before battery failure occurs. By detecting collision or fire conditions and transitioning the door handle to the pulled-out state while the system is still functional, the invention ensures door accessibility is maintained even when subsequent battery failure would otherwise prevent any electrical control operations.
3Reliability
If the vehicle control apparatus detects external objects and controls braking, then collision avoidance is improved, but the door handle state management during collision events needs to be addressed
Solution Approach 1:
The control apparatus uses feedback from the collision detection device to automatically adjust the door handle state. When collision is detected, the system receives feedback signals and automatically transitions the door handle to the pulled-out state, ensuring that post-collision door accessibility is maintained without requiring manual intervention.

AI summary
A vehicle control apparatus includes a processor, a forward detection device configured to identify an external object in front of the vehicle, a door handle driving device configured to control a position of a door handle relative to a door part of the vehicle, and a collision detection device configured to identify whether there is a collision of the vehicle. The processor is configured to identify whether a first signal is received from the forward detection device based on a speed of the vehicle and a distance between the vehicle and the external object, to transmit a second signal to the door handle driving device for moving the door handle to a first position outward relative to the door part, and to maintain a state where the door handle is at the first position based on receiving a third signal from the collision detection device.
