DETECTING ANOMALIES USING REAL-TIME CONTROLLER PROCESSING ACTIVITY

Disclosed embodiments relate to identifying Electronic Control Unit (ECU) anomalies in a vehicle. Operations may include 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.
