Solution Overview
Problem
Existing mobile object monitoring systems, such as those described in Patent Literature 1, face challenges in accurately and reliably detecting unknown mobile objects within blind spots, which can lead to traffic accidents and safety concerns for automated vehicles.
Innovation Solution
A mobile object monitoring system comprising terminal units and a monitoring unit that collect and integrate time-of-absence information sets via vehicle-to-vehicle or vehicle-to-roadside communication to determine the presence or absence of unknown mobile objects in blind spots, enhancing the reliability of absence information through overlapping time ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single observation point is used to detect unknown mobile objects, then the device complexity is reduced, but the measurement precision and reliability of detecting objects in blind spots deteriorates
Solution Approach 1:
The system divides the observation function into multiple terminal units distributed at different locations. Each terminal unit independently observes its local area and generates time-of-absence information sets, which are then integrated by the monitoring unit to achieve comprehensive coverage and eliminate blind spots without requiring a single complex observation system
Solution Approach 2:
The system combines observations from multiple terminal units by integrating their time-of-absence information sets at the monitoring unit. This merging of distributed simple observation points creates a collective detection capability that exceeds the precision of any single observation point, resolving the contradiction between system simplicity and detection accuracy
2Reliability
If multiple terminal units are deployed to improve detection reliability, then the measurement precision increases, but the device complexity and quantity of components increases
Solution Approach 1:
Each terminal unit is designed as a universal, multi-functional component that can independently perform observation, generate time-of-absence information sets, and communicate with the monitoring unit. This standardization allows multiple identical units to be deployed without proportionally increasing system complexity, as each unit performs the same set of functions independently
Solution Approach 2:
The system implements feedback through the collection and integration of time-of-absence information sets from multiple terminal units at the monitoring unit. This feedback mechanism allows the system to cross-validate observations, establish reliability based on the number of overlapping information sets, and improve detection reliability while maintaining manageable system complexity through automated information processing
3Reliability
If time-of-absence information from multiple sources is integrated, then the reliability of absence information increases, but the loss of time for information processing increases
Solution Approach 1:
Terminal units continuously observe and pre-generate time-of-absence information sets in advance, storing them locally before any integration is needed. This preliminary action ensures that when the monitoring unit needs to integrate information to establish reliability, the data is already prepared and available, minimizing the actual processing time while maintaining high reliability through the integration of multiple pre-collected information sets

AI summary
A mobile object monitoring system including a terminal unit installed in a vehicle and a monitoring unit configured to monitor an unknown mobile object around the vehicle. The terminal unit includes: an information acquisition component that acquires unknown mobile object information including information on presence or absence of an unknown mobile object; a determination component that determines presence or absence of an unknown mobile object regarding a blind spot; a time-of-absence information generation component that generates a time-of-absence information set concerning an unknown mobile object that includes absence information of an unknown mobile object in the blind spot and time information on a time of determination; and a communication component that transmits the time-of-absence information set. The monitoring unit receives time-of-absence information sets from terminal units and establishes, regarding the received time-of-absence information sets, reliability of absence information based on the number of time-of-absence information sets with overlapping time ranges that are based on the time information on a time of determination.
