Mobile Object Path Control for Shifted Transport Vehicle Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile objects, such as forklifts, face difficulties in approaching transport vehicles parked in designated parking regions due to shifts in the parking position, leading to inappropriate alignment and inefficient unloading or loading processes.
Innovation Solution
A control method for mobile objects that acquires positional information on transport vehicles, including the position, attitude, and length, to set a first path for precise movement towards the transport vehicle, ensuring accurate alignment and efficient interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the mobile object moves based on a predetermined path in a parking region, then the mobile object can automatically navigate, but it cannot appropriately approach the transport vehicle when the parking position shifts
Solution Approach 1:
The system performs preliminary detection of the transport vehicle's actual position, attitude, and length before generating the approach path. This preliminary action allows the path to be adjusted in advance to match the actual vehicle position, ensuring reliable approach even when parking positions shift.
Solution Approach 2:
The system detects the actual position, attitude, and length of the transport vehicle, then uses this feedback information to generate an appropriate approach path. This closed-loop feedback mechanism ensures that the mobile object can adapt to position shifts and maintain accurate approach capability.
2Device complexity
If the mobile object uses a fixed approach path, then the control system is simple, but it cannot adapt to shifts in the transport vehicle's parking position
Solution Approach 1:
The approach path is made dynamic by continuously detecting the transport vehicle's position, attitude, and length, then generating updated paths based on this real-time information. This dynamic adaptation allows the system to handle position shifts without requiring overly complex control mechanisms.
Solution Approach 2:
The system changes the path parameters (position, attitude, length) based on detected variations in the transport vehicle's actual position. By adjusting these parameters dynamically, the system achieves adaptability to position shifts while maintaining relatively simple control logic.
3Measurement precision
If the mobile object detects the transport vehicle's position, attitude, and length, then it can set an accurate first path, but the detection and measurement complexity increases
Solution Approach 1:
The detection system is designed to simultaneously measure multiple parameters (position, attitude, and length of the transport vehicle) using integrated sensors and processing. This multi-functional approach achieves high measurement precision while avoiding the need for separate complex detection systems for each parameter.

AI summary
A control method is for a mobile object that automatically moves. The control method includes: acquiring positional information on a transport vehicle parked in a parking region including information on a position of a rear end portion of the transport vehicle, information on an attitude of the transport vehicle, and information on a length of the transport vehicle; setting a first path toward the transport vehicle based on the positional information on the transport vehicle; and causing the mobile object to move along the first path.
