Remote Vehicle Control Verification Using Multi-Sensor Command Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles face challenges in determining whether a vehicle is appropriately remotely controlled, especially when multiple vehicles perform similar actions simultaneously or when it is difficult to observe vehicle actions, leading to potential misidentification.
Innovation Solution
A control device and method that generate, transmit, and compare command information, internal sensor information, and external sensor information to detect mismatches, ensuring accurate remote control by comparing parameter values or identification information, and includes mechanisms to prevent erroneous determinations based on situational limitations of sensor usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single sensor (internal or external) is used to verify remote control actions, then the device complexity is reduced, but the reliability of detection deteriorates due to potential misidentification when multiple vehicles perform similar actions simultaneously
Solution Approach 1:
The verification system is segmented into multiple independent information sources: internal sensor information from the target vehicle, external sensor information from surrounding vehicles, and command information. By dividing the verification process into these separate segments and comparing them, the system achieves higher detection accuracy without requiring a single complex sensor
Solution Approach 2:
The system implements feedback by continuously comparing the control command with both internal sensor information from the target vehicle and external sensor information from other vehicles. This feedback mechanism allows the system to identify mismatches and prevent erroneous operations, improving reliability through iterative verification
2Reliability
If multiple information sources are compared to verify remote control actions, then the reliability of detection improves, but the device complexity increases due to multiple sensors and information processing requirements
Solution Approach 1:
The system extracts only the essential verification elements from each information source: the control command parameters, the actual movement parameters from internal sensors, and the movement parameters from external sensors. By extracting and comparing only these critical elements rather than processing all available data, the system maintains high detection accuracy while reducing information processing complexity
Solution Approach 2:
The control device is designed with multi-functionality to handle multiple types of information (command information, internal sensor information, external sensor information) through a unified verification process. This universal approach allows the same device to perform multiple verification functions without proportionally increasing complexity
3Reliability
If internal sensor information is always used for comparison, then the device complexity is reduced, but the reliability deteriorates in situations where internal sensors may be inappropriate or unreliable
Solution Approach 1:
The system dynamically selects which sensor information to use for comparison based on the current situation. When internal sensors are appropriate, they are used; when they are not appropriate, the system switches to using external sensor information. This dynamic adaptability improves detection accuracy without requiring a permanently complex sensor selection mechanism
Solution Approach 2:
The control device automatically determines the appropriateness of internal sensor information and selects the suitable verification source without external intervention. This self-service capability allows the system to maintain high reliability by autonomously adapting to different operational contexts

AI summary
A control device configured to remotely control mobile objects includes: a generation section configured to generate a control command corresponding to each mobile object; a transmission section configured to transmit, to each mobile object, the control command corresponding to the mobile object; an information acquisition section configured to acquire command information related to the control command, internal sensor information related to a state of movement of the mobile object detected by an internal sensor mounted in the mobile object, and external sensor information related to a state of movement of the mobile object detected by an external sensor located outside the mobile object; and a detection section configured to detect that the control command is transmitted from the transmission section to one of the mobile objects not corresponding to the control command, by comparing at least two of the command information, the internal sensor information, and the external sensor information.
