Abstract:
A system for detecting a disruption in a communication system of a vehicle. The system includes a vehicle bus and an electronic processor. The electronic processor is configured to receive a message, from a vehicle bus. The message has a format and a plurality of signals. The electronic processor is configured to detect anomalies in a bus identifier, the message format, a time the message is received, and a signal parameter of a signal of the plurality of signals. The electronic processor is also configured to generate an error if an anomaly is detected in the message format, an anomaly is detected in the time the message is received, or an anomaly is detected in the signal parameter of the signal of the plurality of signals.
