Work Vehicle Dumping Path Control for Irregular Edge Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dumping work efficiency is hindered by the non-uniform shape of the precipice edge in dumping areas, making it difficult for work vehicles to travel and push material efficiently, especially for inexperienced operators.
Innovation Solution
A control system for work vehicles that obtains dumping area and material data to segment the material and determine optimal dumping candidate positions along the edge, allowing for efficient path planning and automatic control of the vehicle to perform dumping work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the work vehicle follows a fixed travel path for dumping work, then the operation is simple, but the work efficiency is reduced due to non-uniform precipice edge shape
Solution Approach 1:
The travel path is made dynamic and adaptive rather than fixed. The control system calculates optimal travel paths in real-time based on the actual precipice edge shape and material distribution, allowing the vehicle to adjust its path dynamically to match the non-uniform terrain conditions.
Solution Approach 2:
The system changes the parameters of the travel path based on measured terrain parameters. By obtaining dumping area data and material data, the control system adjusts the travel path parameters (position, orientation, length) to optimize work efficiency for each specific configuration.
2Ease of operation
If an inexperienced operator performs dumping work, then the operation can be performed, but the work efficiency is significantly reduced
Solution Approach 1:
The system provides self-service through automatic control functionality. The control system automatically calculates optimal travel paths and controls the work vehicle based on obtained terrain and material data, eliminating the need for operator expertise in path planning while maintaining high work efficiency.
Solution Approach 2:
The mechanical skill-based decision-making process is replaced with an automated control system. Instead of relying on operator experience and manual judgment, the system uses automated data processing and control algorithms to determine optimal travel paths.
3Quantity of substance
If the material is pushed repeatedly to accommodate non-uniform edge distances, then all material can be dumped, but the travel distance increases and efficiency decreases
Solution Approach 1:
The system performs preliminary calculation of the optimal travel path before the work vehicle begins movement. By obtaining dumping area data and material data in advance, the control system pre-determines the most efficient path that accounts for the non-uniform edge distances, avoiding repeated pushing operations.

AI summary
A controller obtains dumping area data indicative the shape of an edge of a dumping area. The controller obtains material data indicative the shape of material in the dumping area. The controller decides, based on the material data, a plurality of segments into which the material is divided. The controller decides dumping positions of the dumping work according to combinations of the plurality of segments and the plurality of dumping candidate positions.
