Docking System and Docking Method for Unmanned Vehicles

Unmanned Vehicle Docking Method Generating Docking Paths via Signal Angle of Arrival and Strength Measurement

This technology calculates the relative position and orientation between an unmanned vehicle and a docking station by utilizing Angle of Arrival (AOA) and Received Signal Strength Indicator (RSSI) data from wireless communication signals, subsequently generating a docking path to perform autonomous docking.

Existing LiDAR and image processing-based docking methods involve high sensor costs, are sensitive to environmental factors such as lighting, and require significant computing power to process large datasets like point clouds.

This technology measures and filters wireless signals received from the unmanned vehicle at the docking station to derive AOA and RSSI values, determines the direction of movement by calculating changes in measurements over time, and generates a docking path for the unmanned vehicle based on a mathematical formula incorporating predefined gain parameters.

Key Features:

• A step where the docking station within the docking area measures wireless communication signals from the unmanned vehicle to calculate measurement values
• A step where the unmanned vehicle generates a docking path based on the calculated measurement values
• A step where the unmanned vehicle moves along the generated docking path to dock with the docking station
• A measurement calculation step that determines the approach direction of the unmanned vehicle by measuring and filtering the Angle of Arrival (AOA) and signal strength (RSSI) of wireless communication signals
