Working Vehicle Auto-Drive Switching for Partial Manual Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working vehicles are limited by the complete prohibition of automatic travel when manual operation is detected, leading to decreased efficiency.
Innovation Solution
A working vehicle equipped with an automatic driving controller that allows switching between first and second automatic driving modes, enabling at least one operation to be performed manually while others continue automatically, with the controller managing steering, transmission, brakes, and raising/lowering devices based on predetermined positions and manual inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic travel is completely prohibited upon manual operation, then safety and control are improved, but work efficiency decreases
Solution Approach 1:
The patent segments the automatic travel control into multiple independent operation types (steering, acceleration, deceleration, etc.). When manual operation is detected, only the specific operation type being manually controlled is switched to manual mode, while other operation types continue to operate automatically. This segmentation allows partial manual control without completely disabling automatic travel, thereby maintaining work efficiency while ensuring safety for the specific operation being manually controlled.
2Productivity
If all operations are performed automatically, then work efficiency is improved, but maneuverability and adaptability decrease
Solution Approach 1:
The patent implements dynamic switching between automatic and manual modes for different operation types based on real-time operator input. The system continuously monitors for manual operation inputs and dynamically adjusts the control mode for each operation type accordingly. This dynamic adaptability allows the system to maintain high automation for routine operations while seamlessly transitioning to manual control when operator intervention is needed, thereby preserving both efficiency and maneuverability.

AI summary
A working vehicle includes a traveling vehicle body, and an automatic driving controller to perform first automatic driving in which different operations relating to the traveling vehicle body are performed automatically and second automatic driving in which at least one of the different operations is set to be performed manually and another one or more of the different operations other than the at least one of the different operations set to be performed manually continue to be performed automatically.
