Vehicle Communication Failure Detection via Inter-Vehicle Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems fail to detect failures in cellular communication networks effectively, as they rely solely on the affected network for notification, leading to inability to inform occupants of communication outages.
Innovation Solution
An information processing device installed in vehicles, equipped with both a cellular communication module and an inter-vehicle communication module, collects and analyzes communication state data from other vehicles to determine if a failure exists in the cellular network, allowing for alternative notification and communication path establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies solely on the cellular communication network for failure detection and notification, then the system structure remains simple, but the system cannot detect or notify occupants when the cellular network fails
Solution Approach 1:
The patent introduces a second communication module as an intermediary alternative channel. When the cellular communication network fails, this alternative module (using technologies like satellite communication, short-range communication, or other non-cellular networks) enables the system to still detect and notify occupants of the failure, thus resolving the contradiction between maintaining simple structure and achieving reliable failure detection.
2Reliability
If the system uses only the affected cellular network for sending failure notifications, then energy consumption is minimized, but notification capability is lost when the network is down
Solution Approach 1:
The system performs preliminary action by establishing and maintaining a second communication module as a standby alternative before failure occurs. This module remains ready to use but consumes minimal energy in normal operation. When cellular network failure is detected, the system switches to this pre-prepared alternative channel for notification, ensuring reliable delivery without continuously consuming high energy.
3Reliability
If the system implements alternative communication paths for failure notification, then notification reliability improves, but the system complexity increases
Solution Approach 1:
The second communication module is designed with multi-functionality, serving both as a primary communication channel in certain scenarios and as a backup alternative when cellular network fails. This universal design allows the system to achieve reliable notification through a single integrated module rather than requiring completely separate dedicated backup systems, thereby reducing overall system complexity while maintaining high reliability.

AI summary
An information processing device installed in a vehicle that includes a first communication module for performing communication with a cellular communication network, a second communication module for performing communication among vehicles, and a control unit that executes receiving, from one or more other vehicles via the second communication module, communication state data relating to a state of communication with the cellular communication network, and determining whether a failure is occurring on the cellular communication network, based on a state of communication via the first communication module, and the communication state data.
