Vehicle Cyberattack Response Control for Online and Offline States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control devices struggle to implement appropriate measures against cyber-attacks when wireless communication is not possible, making it difficult to ensure vehicle safety.
Innovation Solution
A vehicle control device that detects cyber-attacks and determines the online or offline state of the in-vehicle system, adjusting vehicle behavior accordingly to enable safe measures, such as stopping or transitioning to a fallback operation, and notifying the surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control device transmits security event information to the security center when wireless communication is possible, then the vehicle can obtain response instructions from the security center, but when wireless communication is not possible, the vehicle cannot obtain real-time response instructions and can only notify predetermined instructions
Solution Approach 1:
The patent applies dynamics by making the vehicle control system adaptable to different communication states. The control device dynamically switches between online mode (communicating with security center) and offline mode (using predetermined instructions) based on wireless communication availability. This dynamic adaptation ensures reliable security response while managing system complexity through state-based control strategies.
2Reliability
If the vehicle control device forcibly stops the vehicle when a cyber-attack is detected, then the vehicle safety is improved, but when wireless communication is not possible, the vehicle cannot implement appropriate measures and may cause unnecessary stopping
Solution Approach 1:
The patent implements feedback mechanisms where the vehicle control device continuously monitors wireless communication status and cyber-attack detection results. Based on this feedback, the system intelligently determines whether to stop the vehicle or continue operation with predetermined instructions. This feedback-based decision-making improves vehicle safety while avoiding unnecessary stopping by considering real-time communication availability and attack severity.

AI summary
A vehicle control device includes: a detector that detects a cyber-attack on an in-vehicle system provided in a vehicle; a determiner that determines whether a state of the in-vehicle system is an online state or an offline state when the cyber-attack is detected; and a controller that makes a behavior of the vehicle related to travelling of the vehicle different between a case where the state of the in-vehicle system is determined to be the online state by the determiner and a case where the state of the in-vehicle system is determined to be the offline state by the determiner. The online state is a state in which communication is possible between the in-vehicle system and equipment outside the vehicle via a communication network, and the offline state is a state in which such communication is not possible.
