Vehicle Hatch Intent Detection Without Movement Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting a user's intention to open a vehicle hatch, such as those using movement sensors, are prone to false positives and negatives due to sensitivity to spurious movements, leading to undesired hatch openings.
Innovation Solution
A system that uses an identifier to record and authenticate a command confirming the user's intention to open a hatch, communicating with an electronic control unit to verify and send a command signal only when the intention is confirmed, eliminating the need for movement sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If movement sensors are used to detect user intention, then automatic hatch opening is enabled, but false positives occur due to sensitivity to spurious movements
Solution Approach 1:
The system performs preliminary authentication of the identifier and verification of intention through multiple confirmation methods (movement pattern analysis, proximity detection, or user input) before executing the hatch opening action, preventing false positives from spurious movements
Solution Approach 2:
The system incorporates feedback mechanisms by analyzing movement patterns, detecting identifier proximity, and requiring confirmation through multiple channels before opening the hatch, allowing it to distinguish between intentional user actions and spurious movements
2Extent of automation
If movement sensors are used to detect user intention, then automatic hatch opening is enabled, but false negatives occur when foot passage is not recognized
Solution Approach 1:
The system employs multiple detection methods including movement sensors, identifier proximity detection, and alternative confirmation inputs (buttons, voice, touchscreen) to cover various user scenarios, ensuring reliable detection whether the user kicks, approaches with an identifier, or uses manual confirmation
Solution Approach 2:
The identifier acts as an intermediary carrier of user intention, detecting its proximity to the hatch or receiving user inputs (button presses, voice commands, touchscreen selections) to convey opening intention to the control system, compensating for failures in direct movement detection
3Extent of automation
If movement sensors are used to detect user intention, then automatic hatch opening is enabled, but system cost increases
Solution Approach 1:
The patent extracts and removes the expensive and unreliable movement sensors from the system, replacing them with a combination of existing identifier technology and simpler detection methods that achieve the same automatic opening function at lower cost
Solution Approach 2:
The identifier serves multiple functions including authentication, proximity detection, and intention communication, allowing the system to eliminate dedicated movement sensors and reduce overall system complexity and cost

AI summary
A system for detecting an intent to open a hatch of a vehicle includes an identifier having means for recording the intent to open a hatch, where the identifier authenticates itself with an electronic control unit, and receives from the ECU a request for confirmation of intent to open a hatch. Following receipt of the request for confirmation of intent to open a hatch, the existence of a command confirming intent to open a hatch in a memory in the identifier is verified. When the command is initiated, a command signal is sent corresponding to the command confirming intention to open a hatch. The electronic control unit is integrated in the vehicle and authenticates the identifier, locates the identifier in proximity to the hatch, sends the request for confirmation of intent to open a hatch, and receives the command signal corresponding to the command confirming intent to open a hatch.
