Database Managing System for Traffic Event Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining an up-to-date database of traffic-affecting events for self-driving vehicles is challenging due to uncertainties about the relevance of reported events, as vehicles may pass by events without detecting or reporting them, leading to inaccuracies in database updates.
Innovation Solution
A database managing system that determines a vehicle's position relative to reported traffic events, prompts the vehicle to verify these events, and updates the database based on the vehicle's response regarding observability and detection, thereby ensuring accurate information about the events is maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a vehicle passes by a reported traffic-affecting event without detecting or reporting it, then the database update process is simplified, but the accuracy and reliability of the database information deteriorates
Solution Approach 1:
The system implements a feedback mechanism where vehicles are prompted to verify reported traffic events by detecting whether they can unobstructedly observe the expected position of the event. The vehicle's detection result is fed back to the database managing system, which then updates the event information accordingly. This closed-loop feedback ensures that database accuracy is maintained while keeping the update process systematic and manageable.
2Reliability
If the system prompts vehicles to verify every reported traffic event, then the accuracy of database information improves, but the complexity of the system and communication overhead increases
Solution Approach 1:
The database managing system performs preliminary actions by pre-calculating and storing the expected position of each reported traffic event. When a vehicle approaches the area, the system promptly provides the expected position information to the vehicle, enabling the vehicle to quickly verify the event without needing to perform complex searches or analyses. This preliminary preparation reduces real-time computational complexity while maintaining verification accuracy.
3Ease of operation
If the system waits for vehicles to naturally detect and report traffic events, then the system operation is simpler, but the timeliness and currency of the database information deteriorates
Solution Approach 1:
The system enables vehicles to self-verify traffic events by providing them with the expected position information and relying on their own detection capabilities. Vehicles autonomously determine whether they can unobstructedly observe the event at the expected position and report their findings back to the database. This self-service approach maintains operational simplicity while significantly improving timeliness, as vehicles actively verify events rather than waiting for passive detection or manual reporting.

AI summary
The present disclosure relates to a method performed by a database managing system (1) for maintaining a database (2) comprising reported traffic-affecting events. The database is associated with a system (3) supporting communication with one or more vehicles. The database derives (1001) a position (421) of a first vehicle (4) supporting detection of vehicle surroundings and determines (1002) by comparing the vehicle position to positions of reported traffic-affecting events comprised in the database, that the first vehicle is approaching at least a first traffic-affecting event (5). The database managing system moreover prompts (1003) the first vehicle to attempt to detect the first traffic-affecting event, which prompting comprises providing to the first vehicle an expected positions (21) of the first traffic-affecting event. The database managing system further receives (1004) a response (12) from the first vehicle, which response indicates whether or not the expected position was at least partly unobstructedly observable by the first vehicle. The response further indicates - if the expected position was at least partly unobstructedly observable - whether or not the first traffic-affecting event was at least partly detected by the first vehicle. Moreover, the database managing system updates (1005), in the database, information associated with the first traffic-affecting event, depending on the response. The disclosure also relates to a database managing system in accordance with the foregoing, and one or more servers and/or automotive clouds at least partly comprising such a database managing system. The disclosure further additionally relates to a traffic-affecting event verifying system (40) on-board a vehicle and a method performed therein, and a vehicle at least partly comprising such a traffic-affecting event verifying system.
