Abstract

An approach for monitoring a data transmission system that uses a data transmission means such as a vehicle bus or a vehicle network of a motor vehicle. This system includes a monitoring device that transmits a request message to a transmitting device and to a receiving device. The transmitting device generates a particular transmitter response on the basis of the request message, where the transmitter response is transmitted to the monitoring device. The receiving device generates a particular receiver response on the basis of the request message, where the receiver response is transmitted to the monitoring device. The monitoring device receives the transmitter response and the receiver response and checks compliance with a trigger condition which depends on the transmitter response and the receiver response, the compliance of which indicates an event relevant to monitoring.
