Fleet Notification System for Coordinated Vehicle Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fleet services primarily handle events on a vehicle-by-vehicle basis, lacking the ability to coordinate responses among nearby vehicles when an event occurs, which limits cooperative handling of incidents such as suspicious person detections.
Innovation Solution
An information notification system comprising a management device with a first and second management unit, and edge devices mounted on vehicles, which collect vehicle data, detect events, and transmit notifications to select notification destinations based on geofenced areas, enabling coordinated responses among registered vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fleet services handle events on a vehicle-by-vehicle basis, then device complexity is reduced and ease of operation is improved, but the ability to coordinate responses among nearby vehicles deteriorates
Solution Approach 1:
The patent merges individual vehicle event handling with fleet-wide coordination by combining the first management unit (handling individual vehicle data) and the second management unit (handling fleet-wide coordination) into a single management device. This allows the system to maintain simple individual vehicle operations while enabling cooperative response among nearby vehicles through geofence-based notification routing.
2Adaptability or versatility
If the system notifies all registered vehicles of every event, then the cooperative response capability is improved, but the loss of information increases due to excessive notifications
Solution Approach 1:
The patent applies local quality by making notification relevance location-dependent. The second management unit determines whether to notify other vehicles based on whether they are located within a geofence area related to the event. This ensures that only vehicles with local relevance to the event receive notifications, maintaining cooperative response capability while filtering out irrelevant information.
3Productivity
If the system collects and processes vehicle data from all edge devices, then the productivity of event response is improved, but the use of energy increases due to continuous data transmission and processing
Solution Approach 1:
The patent applies preliminary action by having the first management unit continuously collect and store vehicle data (including position information) from all edge devices before events occur. This pre-collected data is then quickly retrieved and used by the second management unit for rapid event response coordination, improving productivity while avoiding the need for continuous real-time data transmission during events.

AI summary
An information notification system includes a management device having a first management unit and a second management unit; and an edge device mounted on a vehicle. The edge device includes a data providing unit configured to collect vehicle data including position information of an edge-equipped vehicle, together with a state of the edge-equipped vehicle, and provide the vehicle data to the first management unit; and an event transmission unit configured to detect occurrence of a preset event and transmit an event notification including identification information for identifying the edge-equipped vehicle and type information indicating a type of the event to the second management unit. The first management unit includes a storage unit. The second management unit includes a data collection unit, a receiving unit, a geofence setting unit, a notification destination selection unit, and a notification unit.
