Track Planning Unit for Moving Apparatuses in Multi-Lane Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing moving apparatuses in environments with multiple lanes and obstacles are inefficient due to the inability to shorten moving distances and the burden of detailed movement control, leading to suboptimal operation.
Innovation Solution
An information processing apparatus that determines a passing point with the highest moving efficiency within a non-interference range with other moving apparatuses, sets a track from the starting point to this passing point, and updates the starting point to optimize movement paths, allowing for efficient operation by thinning passing points and considering lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If many waypoints are provided to perform detailed movement control, then the moving apparatus can follow the designated lane accurately, but the moving apparatus has a large burden of track control using the waypoints
Solution Approach 1:
The patent segments the track control task by dividing waypoints into two categories: passing points (for lane designation) and determination points (for efficiency optimization). This segmentation allows the system to reduce the number of control points while maintaining track accuracy, thereby reducing the control burden on the moving apparatus.
Solution Approach 2:
The patent applies partial action by selectively providing waypoints only at critical locations (passing points and determination points) rather than continuously along the entire track. This partial provision of control points reduces the overall burden while maintaining sufficient control precision for safe and efficient operation.
2Reliability
If a lane is designated for the moving apparatus, then the moving apparatus can operate in an organized manner, but the moving apparatus cannot shorten the moving distance to the destination by passing through an inner lane
Solution Approach 1:
The patent makes the lane assignment dynamic by allowing the moving apparatus to change lanes at determination points based on real-time conditions. The track planning unit can designate passing points on different lanes (including inner lanes) as determination points, enabling the apparatus to dynamically optimize its path while maintaining organized operation through structured waypoint management.
Solution Approach 2:
The patent changes the parameter of lane selection by allowing the moving apparatus to transition between different lane parameters (outer lane, inner lane, intermediate lane) at determination points. This parameter change enables the system to balance between organized operation (through lane designation) and moving efficiency (by selecting optimal lanes at key points).
3Productivity
If the width of the movable region is wide, then the manager can easily let moving apparatuses pass each other by providing a plurality of lanes, but the system requires detailed lane configuration and conflict control
Solution Approach 1:
The patent segments the lane management function by introducing determination points where lane changes are permitted. Instead of managing continuous lane assignments, the system divides the movement space into segments separated by determination points, allowing apparatuses to pass each other at these designated locations without requiring complex continuous conflict control throughout the entire path.
Solution Approach 2:
The patent introduces determination points as intermediary locations that facilitate safe passing between moving apparatuses. These determination points act as mediators that coordinate lane changes and passing maneuvers, simplifying the overall conflict control mechanism while maintaining high productivity in wide movable regions.

AI summary
A route/track planning unit (37) of a server (30) performs processing of determining a passing point having the highest moving efficiency within a non-interference range with other moving apparatuses in a moving direction from a track starting point of a moving apparatus toward a destination, processing of setting a track from the track starting point to the passing point having the highest moving efficiency, and processing of updating the track starting point to the passing point having the highest moving efficiency. Furthermore, the route/track planning unit (37) repeats these processes until the passing point having the highest moving efficiency becomes the destination, thereby generating a track plan indicating a track for moving efficiently to the destination. The track plan generated by the route/track planning unit (37) is transmitted to the moving apparatus via the communication unit. The server (30) can efficiently operate the moving apparatus (20).
