Vehicle Barrier Control Using Distance-Based RF Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems require manual operation of moveable barriers like garage doors or gates, which can be inconvenient and risky when the driver is focused on driving.
Innovation Solution
A control system for vehicles that uses a radio frequency transceiver and controller to determine the geospatial location relative to a moveable barrier through signal time-of-flight measurements, enabling automatic operation of the barrier based on predefined distances and vehicle positioning, allowing hands-free control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barrier is designed to be highly visible and robust, then safety and reliability are improved, but the barrier becomes a prominent visual feature that may detract from the aesthetic appeal of the surrounding environment
Solution Approach 1:
The barrier incorporates different visual characteristics at different locations: highly visible reflective elements are placed at critical areas where safety is paramount, while other sections use more aesthetically pleasing materials that blend with the environment. This allows the barrier to provide safety where needed without dominating the entire visual landscape.
Solution Approach 2:
Aesthetic cover elements are introduced as intermediary components that wrap around or attach to the functional barrier structure. These covers serve as a visual mediator, hiding the utilitarian appearance of the barrier while preserving its safety function, thus reconciling the conflict between visibility and aesthetics.
2Reliability
If the barrier structure is made robust and permanent, then reliability and safety are improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The barrier system is divided into modular segments that can be independently manufactured, transported, and installed. Each module contains standardized connection points and interfaces, allowing complex barrier structures to be assembled from simpler components, thereby reducing overall installation complexity while maintaining structural integrity and safety.
3Shape
If the barrier is designed to blend with the environment, then aesthetic appeal is improved, but the visibility and warning function may be compromised
Solution Approach 1:
The barrier incorporates dynamic visual elements such as reflective surfaces that adapt their visibility based on environmental conditions. During daytime, the barrier blends with the environment using natural-colored materials, while at night or in low-light conditions, the reflective elements activate to provide high visibility and warning function, thus resolving the conflict between aesthetics and visibility.

AI summary
The present disclosure relates to a control system (1) for a vehicle (3) to enable communication with a moveable barrier (2). The control system (1) includes one or more controller (12) arranged to communicate with the moveable barrier (2). The controller (12) determines a current distance (BVD) of the vehicle (3) from the moveable barrier (2). A control signal (CS-n) is generated in dependence on the current distance (BVD). The control signal (CS-n) is configured to control movement of the moveable barrier (2). Further aspects of the present disclosure relate to a moveable barrier (2); a vehicle (3) and a related method.
