Remote Vehicle Control for Sensor Overlap Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles struggle to accurately track the location of multiple vehicles when they overlap each other due to limitations in sensor information from external cameras or LiDAR, leading to incorrect tracking and potential collisions.
Innovation Solution
A remote controller that generates retreat control values to adjust the motion of vehicles to prevent overlaps by calculating actual distances and applying control values such as acceleration, direction, and rudder angle adjustments based on sensor information, ensuring accurate detection and tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple vehicles are tracked using sensor information from external cameras or LiDAR, then the system can monitor vehicle locations, but when vehicles overlap each other in the sensor information, the tracking accuracy deteriorates and becomes impossible to track correctly
Solution Approach 1:
The system performs preliminary actions by calculating actual distances between vehicles and generating retreat control values before overlaps occur in the sensor information. When the detection unit identifies that vehicles are overlapping or about to overlap, the control value generation unit proactively generates retreat control values to separate them, preventing the tracking accuracy degradation before it happens.
Solution Approach 2:
The system implements a feedback mechanism where the detection unit continuously monitors vehicle positions and overlap conditions in sensor information, feeds this information to the control value generation unit, which then generates appropriate retreat control values. This closed-loop feedback ensures that tracking accuracy is maintained by dynamically adjusting vehicle positions based on real-time overlap detection.
2Measurement precision
If the system generates retreat control values to prevent vehicle overlaps, then tracking accuracy improves, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The remote controller serves multiple functions: it detects vehicle positions, calculates actual distances, determines overlap conditions, generates retreat control values, and transmits control commands. By consolidating these functions into a single multi-functional device, the system improves tracking accuracy without proportionally increasing overall system complexity.
Solution Approach 2:
The system performs self-service by automatically detecting overlaps, calculating required retreat distances, generating appropriate control values, and executing separation commands without external intervention. This automation reduces the need for complex manual control mechanisms while maintaining high tracking accuracy.
3Reliability
If the system calculates actual distances and generates retreat control values for all vehicles, then overlap prevention improves, but the processing time and productivity decrease
Solution Approach 1:
The system applies local quality by focusing retreat control operations only on specific vehicles that are overlapping or about to overlap, rather than processing all vehicles uniformly. The detection unit identifies problematic vehicle pairs, and the control value generation unit generates retreat commands only for those specific cases, maintaining reliability while improving processing efficiency.
Solution Approach 2:
The system implements partial action by generating retreat control values only when necessary - specifically when the detection unit identifies overlapping or potential overlapping vehicles. Instead of continuously adjusting all vehicle positions, the system applies control actions selectively based on actual overlap conditions, thereby preventing overlaps reliably while minimizing unnecessary processing overhead.

AI summary
A remote controller includes: an acquisition unit; a detection unit; a control value generation unit; and a transmission unit. The control value generation unit generates a retreat control value if at least either one of a first case and a second case applies. The first case includes two or more moving objects overlapping each other in the sensor information. The second case includes establishing an expectation before sensor information acquisition that the two or more moving objects overlap each other when the sensor information is acquired. The retreat control value defines the running motion of at least any of the moving objects establishing a locational relationship allowing a detection subject moving object of the moving objects as a subject of detection using the sensor information to be detected by the detection unit without causing an overlap of the detection subject moving object with a different one of the moving objects.
