Detecting anomalies using real-time ECU processing activity
First Claim
1. A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for identifying Electronic Control Unit (ECU) anomalies in a vehicle, comprising:
- monitoring data representing real-time processing activity of the ECU;
receiving comparable data relating to processing activity of at least one other ECU deemed comparable in functionality to the ECU;
comparing the real-time processing activity data with the comparable data, to identify at least one anomaly in the real-time processing activity of the ECU; and
implementing a control action for the ECU when the at least one anomaly is identified;
whereinsoftware on the ECU is mapped to a plurality of functional units, and the ECU is configured to utilize a virtual file system (VFS) to manage and track one or more versions of each of the plurality of functional units, andthe control action includes updating memory addresses of one or more functional units managed by the VFS based on a delta file corresponding to a second version of the software on the ECU, wherein the delta file comprises position-independent code.
