Interlocked Motion Sensing for Obstacle-Blocked Vehicle Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately acquiring the position and orientation of a moving vehicle through unmanned operation, especially when obstacles obstruct the detection by external sensors.
Innovation Solution
A device that includes a motion information acquisition unit to gather data related to the motion state of an apparatus interlocked with the moving vehicle, and a calculation unit that determines the vehicle's position and orientation using this acquired information, even in situations where direct detection by external sensors is hindered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external sensors are used to detect the moving body for unmanned operation, then the position and orientation can be acquired, but detection may be hindered when obstacles are present between the sensor and the moving body
Solution Approach 1:
The patent introduces an intermediary apparatus that moves interlocked with the moving body (vehicle). This intermediary carries sensors or markers that can be detected by external sensors, serving as a mediator to transmit position and orientation information when direct detection of the vehicle is blocked by obstacles. The intermediary effectively bridges the gap between the vehicle and external detection systems.
2Device complexity
If direct detection by external sensors is used, then the detection system is simple, but detection fails when obstacles block the line of sight
Solution Approach 1:
The intermediary apparatus acts as a mobile detection platform that moves with the vehicle. It carries detection markers or sensors that can be observed by external fixed sensors, enabling indirect detection of the vehicle's position and orientation without requiring direct line-of-sight to the vehicle itself, thus maintaining detection accuracy while keeping the external sensor system relatively simple.
Solution Approach 2:
The intermediary apparatus creates a detectable representation or copy of the vehicle's motion state. By attaching detectable markers to the intermediary that moves synchronously with the vehicle, the system creates a surrogate target that can be detected by external sensors even when the actual vehicle is obscured, effectively copying the vehicle's positional information in a detectable form.
