CAN Bus ECU Error Counter Control Against Malicious Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems, particularly those using the CAN bus, are vulnerable to cyber-attacks and technical difficulties, with no efficient, cost-effective means to prevent malicious access or interference with electronic control units (ECUs), allowing unauthorized control of vehicle features and susceptibility to external attacks.
Innovation Solution
A system and method that manipulate ECU operation by using error counters and bit streams to manage ECU status, implementing tolerance rules based on real-time data to mitigate the effects of malicious communications, thereby protecting ECUs from unauthorized access and ensuring vehicle safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If can ends are made reflective to enable RFID tagging, then communication capability is improved, but can corrosion and structural integrity deteriorate
Solution Approach 1:
The reflective portion is segmented from the can body by applying it only to specific end portions rather than the entire can. This segmentation allows the can to have reflective properties for RFID communication at the ends while maintaining non-reflective material properties for the body portions, thus preventing corrosion and maintaining structural integrity.
Solution Approach 2:
The reflective material is applied locally only to the can ends where RFID tagging is needed, rather than uniformly across the entire can. This local quality approach enables communication capability at specific locations while preserving the corrosion-resistant properties of the main can body.
2Loss of information
If RFID tags are applied to can ends, then tracking capability is improved, but manufacturing complexity increases
Solution Approach 1:
The RFID tag is merged with the can end structure itself, where the reflective portion of the can end serves as the tag. This integration eliminates the need for separate tag application processes, reducing manufacturing complexity while maintaining full tracking capability.
Solution Approach 2:
The can end structure serves multiple functions: it provides structural containment for the food product and simultaneously acts as the RFID tag for tracking. This multi-functionality reduces the number of separate components and manufacturing steps required.

AI summary
The present invention extends to methods, systems, devices, for manipulating operation of at least one electronic control unit (ECU) connected to a controller area network (CAN) bus, at least one said ECU comprising at least one error counter, by counting errors associated with at least one said ECU; and generating and broadcasting via said CAN at least one bit stream destined to at least one said ECU, thereby manipulating at least one said ECU status, determined by said ECU error counter and querying for its status state.
