Utility Vehicle Workload Feedback for Automatic Schedule Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility vehicles require manual adjustment of work schedules based on seasonal changes in the serviced working area, which is cumbersome and inefficient.
Innovation Solution
A utility vehicle equipped with an Electronic Control Unit (ECU) that automatically adjusts the work schedule by determining the load of the work unit and reducing work when it is equal to or less than a predetermined value, using a work load determining unit and a work schedule adjusting unit to incrementally adjust the work schedule as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of work schedule is implemented, then work schedule can be adjusted according to seasonal changes, but user effort and operation complexity increase
Solution Approach 1:
The system automatically monitors work load and adjusts the work schedule without user intervention. The ECU determines whether work load is within predetermined limits and autonomously modifies the work schedule, allowing the system to serve itself rather than requiring manual user adjustment.
Solution Approach 2:
The system continuously monitors work load parameters and uses this feedback to automatically adjust the work schedule. The ECU receives information about work conditions and modifies scheduling based on real-time or historical work load data, creating a closed-loop control system that adapts to changing conditions.
2Ease of operation
If work schedule is reduced automatically, then user effort decreases, but work performance may be compromised
Solution Approach 1:
The system uses work load feedback to make intelligent scheduling decisions. By continuously monitoring whether work load remains within predetermined limits, the ECU can reduce the work schedule only when conditions permit, ensuring that work performance requirements are maintained while still providing automatic adjustment benefits.
Solution Approach 2:
The system changes scheduling parameters based on work load conditions. When work load is determined to be within acceptable limits, the ECU modifies schedule parameters to reduce work; when work load exceeds limits, the original schedule is maintained, thus dynamically adjusting parameters to balance automation benefits with performance requirements.

AI summary
In a utility vehicle that runs a working area to perform work with a work unit comprising a blade and work motor it is determined whether load of the work unit in work performed in accordance with an established work schedule is equal to or less than a predetermined value, and the established work schedule is adjusted to reduce work when it is determined that the load is equal to or less than the predetermined value.
