Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic traveling systems for work vehicles face a trade-off between safety and efficiency, as they either stop completely upon obstacle detection, reducing efficiency, or continue traveling, compromising safety.
Innovation Solution
An automatic traveling system that includes an imaging system to detect obstacles, allowing for a traveling stop or continuation instruction based on obstacle detection, thereby balancing safety and efficiency by enabling controlled navigation around detected obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic traveling is stopped upon obstacle detection, then safety is improved, but work efficiency is lowered
Solution Approach 1:
The system dynamically adjusts the automatic traveling behavior based on the type of obstacle detected. For movable obstacles, the system continues traveling to maintain efficiency, while for immovable obstacles, it stops to ensure safety. This dynamic response resolves the contradiction between safety and work efficiency.
Solution Approach 2:
The system changes the operational parameter (traveling state) based on obstacle characteristics. By detecting whether an obstacle is movable or immovable, the system switches between two operational modes: continuing travel for movable obstacles and stopping for immovable obstacles, thus balancing safety and efficiency.
2Productivity
If automatic traveling is continued upon obstacle detection, then work efficiency is maintained, but safety is compromised
Solution Approach 1:
The system dynamically determines the appropriate response based on real-time obstacle detection results. By classifying obstacles as movable or immovable, the system adaptively selects whether to continue or stop traveling, maintaining efficiency when safe and ensuring safety when necessary.
Solution Approach 2:
The operational parameter (traveling continuation or stop) is changed based on the detected obstacle type. The system transitions between different operational states according to whether the obstacle can be moved, thereby resolving the safety-efficiency trade-off.
3Reliability
If uniform stopping is applied upon obstacle detection, then safety is ensured, but work efficiency is reduced
Solution Approach 1:
The system applies different stopping behaviors to different types of obstacles rather than uniformly stopping for all obstacles. Movable obstacles receive a different response (continue traveling) compared to immovable obstacles (stop traveling), optimizing the balance between safety and efficiency for each specific case.
Solution Approach 2:
The system transitions from a static uniform stopping policy to a dynamic differentiated response policy. By continuously monitoring obstacle characteristics and adjusting the traveling response accordingly, the system achieves both safety and efficiency.

AI summary
An acquisition processing part acquires a captured image from a camera which is installed on a work vehicle. A detection processing part detects an obstacle on the basis of the captured image which is acquired by the acquisition processing part. When an obstacle is detected by the detection processing part, a reception processing part receives a traveling stop instruction for stopping automatic traveling of the work vehicle or a traveling continuation instruction for continuing automatic traveling of the work vehicle. A traveling processing part stops the automatic traveling of the work vehicle when the reception processing part receives the traveling stop instruction, and continues the automatic traveling of the work vehicle when the reception processing part receives the traveling continuation instruction.
