Abstract: A vehicle data bus system having one or more data buses, via which a plurality of connected bus users are connected for data transmission, having a sensor module which is embodied as a bus user and has a rotational speed sensor, the sensor module being configured to output rotational speed data onto the data bus, and having a vehicle movement dynamics/wheel slip control system which is embodied as a bus user and which is designed to receive at least the rotational speed data via the data bus. At least one further bus user is designed to receive the rotational speed data via the data bus, the sensor module is configured to preprocess the rotational speed data and to output the preprocessed rotational speed data onto the data bus, and the vehicle movement dynamics/wheel slip control system and/or the further bus user are configured to perform an offset correction of the received preprocessed rotational speed data.
