Remote Vehicle Control Verification Using Mark-Based Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately determine whether remote control instructions are sent to the intended vehicle, as non-target vehicles may inadvertently perform the same operations, leading to misidentification and potential errors.
Innovation Solution
A control device that acquires actual data from a mark displayed on a moving object using a sensor, compares it with reference data, and performs different processes based on the match or mismatch to ensure instructions are sent to the correct vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control instructions are sent based on standard operations, then ease of operation is improved, but reliability deteriorates because non-target vehicles may perform the same operation
Solution Approach 1:
The system uses a sensor to detect whether the instructed operation has been performed, and feeds this information back to determine if the instruction was successfully sent to the target vehicle. This feedback mechanism allows the system to verify target vehicle identification accuracy by confirming that the detected operation matches the instructed operation, thereby resolving the reliability issue while maintaining ease of operation.
2Measurement precision
If sensor detection is used to confirm operation performance, then measurement precision is improved, but device complexity increases due to additional sensors and detection mechanisms
Solution Approach 1:
The system introduces a sensor as an intermediary element that detects operation performance and transmits this information to the control device. This intermediary approach enables accurate measurement of whether the instructed operation was performed, while keeping the overall system complexity manageable by using a dedicated detection component rather than complex integrated systems.
3Ease of operation
If non-unique information is used for identification, then ease of operation is improved, but reliability deteriorates because multiple vehicles share the same information
Solution Approach 1:
The system uses feedback from the sensor to verify whether the detected operation matches the instructed operation. This feedback mechanism allows the system to distinguish between target and non-target vehicles even when they share the same non-unique identification information, by confirming that only the target vehicle performed the instructed operation.
Data Source
AI summary
The control device includes: an actual data acquisition unit that acquires at least one of a mark displayed on an external monitor mounted on a moving object that can be moved by remote control, acquired information that is acquired using the mark and includes identification information for identifying the moving object; a reference data acquisition unit that acquires reference data corresponding to the actual data; and a remote control unit that remotely controls the moving object, in which a process related to the movement of the moving object is different between a case where the actual data and the reference data match and a case where the actual data and the reference data do not match.
