Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle control systems delay the start of anomaly detection due to the need to determine a suitable state before initiating data communication, leading to potential delays in identifying communication anomalies.

Innovation Solution

A vehicle control system where data is transmitted via a first path and a trigger signal is sent via a second distinct path to initiate communication anomaly detection, allowing simultaneous and prompt initiation of anomaly detection upon data transmission.

1Reliability

If anomaly detection is performed only after determining a suitable state, then detection reliability is improved, but detection speed deteriorates

Engineering Contradiction:

Improveanomaly detection reliabilityVSAvoiddetection delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by transmitting data via the first communication path and simultaneously sending a trigger signal via the second communication path before anomaly detection is fully initiated. This preliminary transmission setup ensures that when the trigger signal is received, the detection can start immediately without waiting for state determination, thus reducing detection delay while maintaining reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The trigger signal acts as an intermediary between data transmission and anomaly detection initiation. The trigger signal is transmitted via the second communication path and serves as a mediator that signals the second control device to start anomaly detection. This intermediary mechanism decouples the state determination requirement from the detection initiation, allowing faster response.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If data and trigger signal are transmitted via the same path, then system complexity is reduced, but detection timing precision deteriorates

Engineering Contradiction:

Improvetransmission path complexityVSAvoiddetection timing precision

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The transmission system is segmented into two separate communication paths: the first communication path for data transmission and the second communication path for trigger signal transmission. This segmentation allows independent control and timing of data transmission and detection initiation, ensuring precise timing control for anomaly detection while dividing the system into functional segments.

AI summary

A control system for a vehicle includes a first control device and a second control device that receives data transmitted by the first control device and determines a communication anomaly of the data. When the first control device starts transmission of data to the second control device via the first transmission path, the first control device transmits a signal serving as a trigger for starting determination of a communication anomaly to the second control device via a second transmission path different from the first transmission path. Upon receiving the signal from the first processing circuitry, the second control device starts determination of a communication anomaly.
