A subscriber station for a serial bus system and a method for communicating in a serial bus system. The subscriber station includes a communication control device for controlling a communication of the subscriber station with at least one other subscriber station of the bus system, a transmitting/receiving device for receiving a transmission signal generated by a communication control device of a subscriber station of the bus system in a frame from a bus of the bus system and for generating a reception signal from the received frame, and a connection quality block for detecting and evaluating a quality of a communication connection to a subscriber station of the bus system from the reception signal generated by the transmitting/receiving device by using at least two time quanta, into which the bit time of a bit of the generated reception signal is subdivided.

A process detects anomalies on a controller area network (CAN) bus. An arbitration field in a message on the CAN bus is analyzed, and a data field in the message on the CAN bus is inspected. The process further monitors a frequency of message identifiers that are transmitted across the CAN bus, and determines that an overall bus load crosses a threshold. The process then transmits an alert when the analyzing the arbitration field, the inspecting the data field, the monitoring the frequency, and the determining the overall bus load indicate that an anomaly has occurred on the CAN bus.
