Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication with the outside is interrupted when a cyber-attack is detected, then security against cyber-attack is improved, but loss of information is worsened

Engineering Contradiction:
Improvesecurity against cyber-attackVSAvoidinformation loss
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary action by notifying the driver before interrupting communication. This ensures the driver is aware of the cyber-attack and the upcoming communication interruption, reducing information loss while maintaining security through subsequent communication blocking.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the driver about the cyber-attack detection and upcoming communication interruption. This feedback mechanism ensures the driver understands the situation and the reasons for communication blocking, reducing information loss while maintaining security.

Inventive Principle:
Principle #23Feedback

AI summary

A vehicle behavior control method is disclosed. The method includes detecting, acquiring, determining, and changing. The detecting is to detect a cyber-attack on a vehicle. The acquiring is to acquire situation information including at least one of information about a situation of the vehicle or information about a situation around the vehicle. The determining is to determine, based on the situation information, a safety level related to a countermeasure against the cyber-attack. The changing is to change a vehicle behavior of the vehicle related to the countermeasure against the cyber-attack in accordance with the safety level.
