Adaptive Vehicle Cybersecurity Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle cybersecurity systems lack adaptive measures to effectively respond to cyber-attacks based on the vehicle's environment and situation, as they do not adequately consider the dynamic nature of threats and resource availability.
Innovation Solution
A vehicle computer system equipped with sensors to gather environmental data and a controller that identifies cyber-attacks, determines the appropriate security protocol, and adjusts vehicle settings to respond to threats by activating or deactivating communication interfaces and security services based on the vehicle's state, location, and user demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed security protocol is activated to protect against cyber-attacks, then security reliability is improved, but vehicle performance and user experience deteriorate due to unnecessary restrictions on communication and system operations
Solution Approach 1:
The security system dynamically adjusts the security protocol based on real-time analysis of vehicle environment, operational state, and threat level. The controller modifies security parameters such as communication restrictions and system access controls according to current conditions, transitioning between secure and performance-oriented modes as needed.
Solution Approach 2:
The system changes security parameters including communication interface activation states, protocol strictness levels, and system access restrictions based on environmental inputs and threat assessments. This allows the security posture to be adjusted continuously rather than maintaining a fixed state.
2Measurement precision
If comprehensive security monitoring is implemented to detect all cyber-attacks, then security detection capability is improved, but system complexity and computational resource consumption increase
Solution Approach 1:
The security system applies different levels of monitoring and analysis to different vehicle systems and communication interfaces based on their risk profiles. Critical systems receive enhanced scrutiny while less critical functions use standard monitoring, optimizing resource allocation across the vehicle network.
Solution Approach 2:
The controller implements security monitoring at appropriate levels without over-engineering the system. Security measures are applied selectively based on threat assessment rather than universally across all systems, avoiding unnecessary complexity while maintaining adequate protection.
3Object-affected harmful factors
If strict security protocols are enforced to block all external communications, then security protection is improved, but ease of operation and system functionality deteriorate
Solution Approach 1:
Communication restrictions are dynamically adjusted based on the current security context. When threats are detected, external communications are restricted; when the environment is safe, normal communication functionality is restored. This allows the system to maintain both security and usability appropriately.
Solution Approach 2:
The system prepares security measures in advance by establishing protocols that can be quickly activated when threats are detected. Communication interfaces are configured to be secure by default but can be rapidly opened when needed, preventing both attacks and unnecessary operational restrictions.

AI summary
A vehicle computer system includes one or more sensors configured to receive input regarding a vehicle's environment, and a controller in communication with the one or more sensors of the vehicle. The controller is configured to identify a cyber-attack on one or more vehicle controllers in the vehicle, and respond to the cyber-attack based upon at least the vehicle environment.
