Remote Vehicle Control Mapping for Mismatched Operation Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mismatch between the maximum operation range of a remote operation member and the vehicle's operation range can lead to deteriorated remote operability when operating vehicles of varying sizes and configurations.
Innovation Solution
A remote operation method and device that adjust the correspondence relationship between the operation amounts of the remote operation member and the vehicle, or restrict the operable range of the remote operation member, to match the vehicle's maximum operation range, ensuring appropriate remote operability regardless of 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 with different sizes and configurations, then the device complexity is reduced, but the remote operability deteriorates due to mismatch between the remote operation member's maximum operation range and the vehicle's maximum operation range
Solution Approach 1:
The patent implements dynamic adjustment of the correspondence relationship between remote operation member operation amounts and vehicle operation member operation amounts. The adjustment unit changes the mapping relationship based on the type of vehicle being operated, allowing the same remote operation member to adapt to different vehicle operation ranges. This dynamic reconfiguration resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The patent changes the parameter of the correspondence relationship between operation amounts. By adjusting the mapping parameters (how remote operation member movement translates to vehicle operation member movement), the system can accommodate different vehicle types with different operation ranges while using the same remote operation member, thus maintaining both low device complexity and high remote operability.
2Device complexity
If the maximum operation range of the remote operation member is smaller than the vehicle's maximum operation range, then the device complexity is reduced, but the remote operability deteriorates because the vehicle cannot be fully operated
Solution Approach 1:
The adjustment unit modifies the correspondence relationship parameters to amplify the effect of the remote operation member's limited operation range. By changing the mapping ratio or transformation parameters, the system enables the remote operation member to control the vehicle's full operation range despite having a smaller physical range itself.
Solution Approach 2:
The remote operation member is designed to be universal across different vehicle types. The adjustment unit provides the multi-functionality needed to make a single remote operation member work effectively with vehicles having different operation ranges, allowing one device to serve multiple purposes and vehicle types.
3Adaptability or versatility
If the maximum operation range of the remote operation member is larger than the vehicle's maximum operation range, then the adaptability is improved, but the remote operability deteriorates due to excessive operation range that cannot be utilized
Solution Approach 1:
The adjustment unit modifies the correspondence relationship to restrict or scale down the effective operation range of the remote operation member to match the vehicle's operation range. By changing the mapping parameters, the system eliminates the mismatch caused by excessive remote operation range, ensuring that the full range of the remote operation member is productively utilized.
Solution Approach 2:
The system extracts or removes the excess operation range from the remote operation member through the adjustment unit. By selectively mapping only the necessary portion of the remote operation member's range to the vehicle's operation range, the system eliminates the harmful effect of excessive range while maintaining adaptability.

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.
