Vehicle Door Voice Control With Mobile Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door opening systems, such as automatic tailgates and hands-free systems, often unintentionally open when the user does not intend to do so, or require inaccurate kicking motions, causing inconvenience.
Innovation Solution
A voice control system using a communication device to detect and authenticate a mobile device, a voice receiving device to capture commands, and a voice control device to recognize and execute voice commands for door operation, adjusting the opening height based on the user's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic tailgate system is used, then door opening convenience is improved, but unintended door opening occurs when user approaches without intention
Solution Approach 1:
The system uses feedback from multiple sensors (weight sensor, proximity sensor, operation sensor) to continuously monitor user intent and adjust door opening behavior accordingly. The control unit processes feedback signals to determine whether to open the door, preventing unintended openings while maintaining convenience.
Solution Approach 2:
The system performs preliminary detection of user intent through weight sensing and proximity detection before executing door opening. By detecting whether the user is carrying luggage or standing in the loading area beforehand, the system prepares to open the door only when appropriate, avoiding unintended activations.
2Ease of operation
If hands-free kicking system is used, then door opening convenience is improved, but inaccurate kicking motion is required leading to operation failure
Solution Approach 1:
The operation sensor provides feedback on kicking detection status to the control unit. The system continuously monitors for kicking motions and provides feedback signals to confirm successful detection, allowing the user to adjust their kicking motion if not recognized, thereby reducing the precision requirement.
Solution Approach 2:
The system automatically detects and responds to kicking motions without requiring precise user input. The weight sensor and operation sensor work together to self-identify kicking actions, eliminating the need for users to perform highly accurate kicking motions.
3Reliability
If voice control system is added, then door opening reliability is improved, but device complexity increases
Solution Approach 1:
The voice recognition unit is merged with the existing control unit, allowing voice commands to be processed alongside other control signals. This integration enables reliable voice-controlled door opening without requiring a completely separate control system, thus limiting the increase in complexity.
Solution Approach 2:
The control unit is designed to handle multiple input types (weight sensor, proximity sensor, operation sensor, and voice commands) through a single unified interface. This multi-functionality allows the system to improve reliability through voice control while avoiding the complexity of multiple separate control systems.

AI summary
A voice control system includes a communication device, a voice receiving device, and a voice control device. The communication device is configured to, when a mobile device of a vehicle user enters a detection range of the communication device, detect a location of the mobile device by communicating with the mobile device and to detect whether the mobile device is authenticated, the voice receiving device is configured to receive voice information of the vehicle user, and the voice control device is configured to control the voice receiving device to receive the voice information from an outside of the vehicle based on whether the authenticated mobile device has entered the detection range, where voice information includes voice information for controlling a door such as a tailgate, a rear trunk lid, or a front trunk lid, and the received voice information is recognized to control a corresponding target vehicle-mounted device.
