Work Vehicle Travel Resumption Control Across Multiple Work Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work travel management systems struggle to effectively resume work travel operations in work vehicles that have been suspended due to fuel depletion, work volume limitations, or other issues, especially in vast work fields, and cannot handle complex scenarios like switching between multiple work fields or resuming at positions other than where work was suspended.
Innovation Solution
A work travel management system that includes a suspension information recording unit, extraction unit, information display unit, resumption information generation unit, and work travel control unit to record, display, and manage suspension and resumption of work travel, allowing users to easily select and resume work travel by displaying critical details and positions, and optionally determining a suitable resumption position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the work vehicle suspends work travel due to fuel depletion, work volume limitations, or other issues, then the vehicle can address these problems by moving to a specified place, but the complexity of managing suspension and resumption increases when dealing with multiple work fields and multiple suspension reasons
Solution Approach 1:
The patent segments the suspension information into distinct categories (suspension reason, work field identification, suspension position, timestamp) and stores them as separate data elements. This segmentation allows the system to handle multiple suspension reasons and work fields independently while maintaining organized, manageable data structures that reduce control complexity.
Solution Approach 2:
The patent creates a digital copy of the suspension state by recording all relevant parameters (position, reason, work field ID, timestamp) in memory. This copy enables the system to restore the exact suspension context without physically returning to the suspension point, simplifying the resumption control process while maintaining full adaptability to different suspension scenarios.
2Duration of action of moving object
If the work field is vast and work travel lasts for multiple days, then the vehicle may need to return to storage and resume work the following day, but conventional control cannot process switching between multiple work fields
Solution Approach 1:
The patent performs preliminary recording of work field identification information and suspension position data before the vehicle returns to storage. This preliminary action ensures that when the vehicle resumes work the following day, it can automatically retrieve the stored information and switch to the correct work field without manual intervention, enabling multi-day operations across multiple fields.
Solution Approach 2:
The system uses feedback by storing and retrieving suspension information including work field IDs and positions. When the vehicle returns after storage, the system provides feedback through the recorded data to guide the vehicle back to the correct work field and suspension position, enabling automatic resumption across multiple fields and days.
3Ease of operation
If the work vehicle needs to urgently move to another work field or a trouble occurs, then the vehicle suspends work travel and goes out of the work field temporarily, but conventional control cannot handle resumption after such temporary departures
Solution Approach 1:
The patent performs preliminary recording of the suspension state (position, reason, work field ID) before the vehicle temporarily leaves the work field. This preliminary action ensures that when the vehicle returns, whether for urgent matters or after troubleshooting, the system can reliably restore the exact work context without manual reconfiguration.
Solution Approach 2:
The system maintains reliability by using feedback from the recorded suspension information. When the vehicle returns to the work field, the system compares the current state with the stored suspension data and automatically adjusts navigation and operations to resume work from the correct position, ensuring reliable resumption after temporary departures.
4Ease of operation
If suspension information is not recorded and displayed, then the system remains simple, but users cannot easily select and resume work travel at the correct position and parameters
Solution Approach 1:
The patent creates a digital copy of the suspension state including position coordinates, suspension reason, work field ID, and timestamp, and stores it in memory. This copy preserves all critical information without adding physical complexity to the system, enabling users to easily select and resume work travel at the exact correct position and parameters.
Solution Approach 2:
The patent introduces an information display unit as an intermediary between the suspension data storage and the user. This intermediary presents the recorded suspension information in a user-friendly format, enabling easy selection and resumption of work travel while maintaining data integrity and preventing information loss.

AI summary
A work travel management system is provided that enables appropriate resumption of work travel even if the work travel is suspended. A work travel management system includes: a suspension information recording unit (602) that records suspension of work travel by a work vehicle as suspension information; a suspension information extraction unit (604) that extracts the suspension information from the suspension information recording unit (602); an information display unit (40) that displays the extracted suspension information; a resumption information generation unit (605) that generates resumption information for resuming the suspended work travel based on the suspension information and causes the information display unit (40) to display the generated resumption information; and a work travel control unit (50) that performs the work travel of the work vehicle based on the resumption information. Further, a method for managing work travel of a work vehicle capable of automatically traveling along a travel route in a work field is provided.
