Abstract: Embodiments and examples are disclosed for intelligent detection of vehicle intrusion using command pattern modeling and analysis. For one example, a vehicle control unit (VCU) may monitor, using a model of a user's expected driving behavior, the user's current driving behavior and detect anomalous driving behavior based on the model. The VCU may determine that the anomalous driving behavior does not correspond to one or more commands on a network bus of the vehicle and analyze, using a command pattern model, a pattern among the one or more commands on the network bus. The VCU may then compare, using the command pattern model, the pattern among the one or more commands to a historical command pattern to determine if an intrusion (e.g., by a hacker) is taking place.
