Closure Panel Release Request Detection Without Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle closure panel detection systems fail to accurately determine if a closure panel is secured in the closed position when environmental conditions such as ice or snow prevent it from moving, leading to potential unexpected opening.
Innovation Solution
A system and method that utilize a processor to receive a closure panel release request and set a condition indicating the panel is not latched, allowing for alerting the user and unlatching the panel without relying on movement detection, using an input device and closure mechanism coupled to the vehicle's electronic control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are installed to detect when closure panel moves away from closed position, then detection accuracy is improved, but the system fails when closure panel cannot move due to environmental conditions
Solution Approach 1:
The system performs preliminary action by setting a release flag when a release request is received, before actually detecting whether the closure panel has moved. This flag indicates that the closure panel should be released, and the system can then alert the user or automatically reclose the panel without waiting for movement detection. This resolves the contradiction by providing a detection method that works regardless of whether the panel can physically move.
2Ease of operation
If closure panel is designed to open when released, then ease of operation is improved, but environmental conditions may prevent opening causing safety issues
Solution Approach 1:
The system applies preliminary anti-action by implementing measures to counteract the harmful effect of environmental conditions before they can cause problems. When a release request is received, the system sets a flag and can alert the user or automatically reclose the panel, preventing the scenario where the panel remains partially open due to ice, snow, or other environmental factors. This proactively counteracts the potential harmful effects of environmental interference.

AI summary
A system and a method are provided for receiving and recording a closure panel release request. The system comprises an input device for transmitting the closure panel release request, a closure mechanism for securing the closure panel in the closed position, and a processor that is coupled to the vehicle, the closure mechanism, and the input device. The processor is configured to receive the closure panel release request and set a condition indicating that the closure panel is released from the closed position.
