Abstract
A bus system includes a plurality of control devices in a motor vehicle, being interconnected by means of a vehicle bus. The data transmitted on the bus are read out by a data module which generates items of information from them that are non-urgent, for example items of statistical information. The items of information are output through the bus as message blocks with a low transmission repetition frequency. They can then be extracted from the individual control devices as required and evaluated. In addition, data which are supplied by various sensors in the motor vehicle are evaluated in the data module.
