Remote Vehicle Input Scaling for Mismatched Control Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing remote driving systems face challenges in maintaining appropriate remote operability when the maximum operation range of the remote operation member and the vehicle do not match, leading to potential deterioration in remote control effectiveness across various types of vehicles.
Innovation Solution
The remote operation method and device adjust the correspondence relationship between the operation amounts of the remote operation member and the vehicle, either by increasing the vehicle's operation amount when the remote member's range is smaller or restricting the remote member's range when it is larger, to ensure appropriate operability regardless of the vehicle type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same remote operation member is used to handle various types of vehicles, then the device complexity is reduced, but the remote operability deteriorates due to mismatched operation ranges
Solution Approach 1:
The patent applies dynamics by making the correspondence relationship between remote operation member and vehicle operation member adjustable rather than fixed. The system dynamically adapts the operation range mapping based on the specific vehicle type, allowing the same remote operation member to effectively control different vehicles with varying operation ranges without requiring multiple specialized controllers
Solution Approach 2:
The patent changes the parameter of operation range correspondence by detecting the vehicle type and automatically adjusting the mapping between the remote operation member's operation range and the vehicle operation member's operation range. This parameter adjustment ensures optimal operability for each vehicle type while using a universal remote operation member
2Length of moving object
If the maximum operation range of the remote operation member is smaller than the vehicle's operation range, then the device size is reduced, but the vehicle cannot be fully operated
Solution Approach 1:
The patent changes the correspondence parameter between remote operation amount and vehicle operation amount. When the remote operation member has a smaller maximum operation range than the vehicle's operation member, the system adjusts the correspondence relationship to amplify the remote operation amounts, enabling full utilization of the vehicle's operation range despite the limited remote controller range
3Adaptability or versatility
If the maximum operation range of the remote operation member is larger than the vehicle's operation range, then the operational flexibility is increased, but the operation becomes unreflected
Solution Approach 1:
The patent changes the correspondence parameter to restrict or scale down the remote operation amounts. When the remote operation member has a larger maximum operation range than the vehicle's operation member, the system adjusts the correspondence relationship so that the vehicle operation amount becomes smaller than the remote operation amount, ensuring that all remote operations are properly reflected within the vehicle's operational limits
Solution Approach 2:
The system uses feedback by detecting the vehicle type and the operation ranges of both the remote operation member and vehicle operation member, then automatically adjusting the correspondence relationship. This feedback mechanism ensures that the remote operation amounts are appropriately mapped to the vehicle's capabilities, preventing unreflected operations while maintaining operational flexibility

AI summary
A vehicle is operated in accordance with a second operation amount corresponding to a first operation amount of a remote operation member by an operator. A first maximum operation range is a maximum operation range of the remote operation member. A second maximum operation range is a maximum operation range of an operation member of the vehicle. When the first maximum operation range is smaller than the second maximum operation range, a correspondence relationship between the first and second operation amounts is adjusted such that the second operation amount becomes larger than the first operation amount. When the first maximum operation range is larger than the second maximum operation range, an operable range of the remote operation member is restricted or the correspondence relationship is adjusted such that the second operation amount becomes smaller than the first operation amount.
