Vehicle Malfunction Reporting Control for Lower Communication Costs

Solution Overview

Problem

Existing systems incur high communication costs due to frequent data transmission from mobile objects for driving assistance, which is inefficient and costly.

Innovation Solution

A control apparatus that receives malfunction occurrence triggers and determines whether to transmit malfunction information based on traveling-related information, only sending it if a predetermined non-transmission requirement is not satisfied, thereby reducing unnecessary transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If malfunction information is transmitted frequently from mobile object to external device, then reliability of driving assistance system is improved, but communication costs increase

Engineering Contradiction:

Improvereliability of driving assistance systemVSAvoidcommunication costs

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent changes the transmission parameter from frequent/regular transmission to conditional transmission based on malfunction occurrence. The control apparatus transmits malfunction information only when specific conditions are met (malfunction detected and non-transmission requirement not satisfied), rather than transmitting at fixed intervals or continuously, thus reducing communication frequency and costs while maintaining system reliability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary filtering and judgment before transmission. The control apparatus evaluates whether a malfunction has occurred and checks if the non-transmission requirement is satisfied before initiating data transmission. This preliminary action prevents unnecessary transmissions and reduces communication costs while ensuring critical malfunction information is transmitted.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If malfunction information is transmitted every time a malfunction occurs, then reliability is improved, but communication frequency increases causing higher costs

Engineering Contradiction:

Improvefault detection reliabilityVSAvoidcommunication efficiency

Core Design Contradiction:

AI summary

In a control apparatus, an acquisition unit receives, from a mobile object, a malfunction occurrence trigger indicative of an occurrence of at least one malfunction in driving assistance of the mobile object, and acquires, from the mobile object, in response to reception of the malfunction occurrence trigger, traveling-related information related to traveling of the mobile object. A control unit is configured to transmit, to an external device, malfunction information upon determination that a predetermined non-transmission requirement is not satisfied based on the traveling-related information, the malfunction information including positional information on the mobile object as malfunction positional information. The control unit is configured not to transmit, to the external device, the malfunction information upon determination that the predetermined non-transmission requirement is satisfied based on the traveling-related information.
