Vehicle Onboard System for Gesture-Based Garage Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal garage door opening systems require manual intervention or carrying a remote terminal, which can lead to inconvenience and security risks, as they lack a seamless and secure method to control garage door access based on driver intent.
Innovation Solution
An onboard vehicle system equipped with an image sensor, control module, and emitter circuit that identifies specific driver behavioral features, such as gestures or lip movements, to send commands to the park area access system, allowing for automated and secure garage door control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention or carrying a remote terminal is used to control garage door access, then the system is simple to implement, but the ease of operation deteriorates due to inconvenience and security risks
Solution Approach 1:
The system enables the vehicle to automatically control the garage door without requiring manual intervention from the driver. The onboard transceiver autonomously transmits the garage door control signal when the vehicle enters the predetermined park area, making the system serve itself rather than requiring continuous human operation.
Solution Approach 2:
The system pre-positions the garage door control signal within the vehicle's onboard transceiver during a learning phase. This preliminary action allows the signal to be ready for immediate automatic transmission when the vehicle enters the park area, eliminating the need for manual remote terminal operation at the moment of access.
2Ease of operation
If the onboard transceiver automatically transmits the garage door signal when the vehicle enters the park area, then the ease of operation improves, but the device complexity increases due to additional sensors and control systems
Solution Approach 1:
The onboard transceiver is designed to serve multiple functions: it can store and transmit various garage door control signals learned during the learning phase, and it can automatically activate based on vehicle location. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The system uses the vehicle's existing onboard transceiver as an intermediary device that bridges between the vehicle's location-based triggering mechanism and the garage door control system. This intermediary approach leverages existing vehicle infrastructure rather than requiring completely new dedicated components.
3Adaptability or versatility
If the learning mode is used to program the onboard transceiver, then the adaptability improves by learning signal characteristics, but the time required for setup increases
Solution Approach 1:
The learning mode captures and stores a copy of the garage door control signal characteristics from the handheld remote terminal. This copying process allows the onboard transceiver to replicate the exact signal properties needed to operate the garage door, enabling flexible adaptation to different garage door systems without complex programming.

AI summary
An onboard system (4) for a vehicle (2) comprising:—an emitter circuit (8) suitable to send a command (C) to a park area access system (22);—an image sensor (6) suitable to capture a sequence of images (S) of at least part of a body of a driver (D) of the vehicle (2); and—a control module (10) suited to process said sequence of images (S) so as to identify a behavioral feature and then control the emitter circuit (8) to send the command (C) to the park area access system (22) provided the identified behavioral feature corresponds to a predetermined behavioral feature. A corresponding process is also proposed.
