Abstract: Data bus system and method are provided for controlling service engagements for bus users. At least one bus user provides services and other bus users use these services. A resource manager stores information about the available services and information about the service-providing bus users. The resource manager reserves a service from a providing bus user if the service can be used, and sends a response to a requesting bus user, allowing the requesting bus user to use the service from the providing bus user via the data bus. Information about the provided services is provided on the data bus via a standard interface by the bus users and a change in the provision of a service by a bus user is made available to the resource manager via the standard interface. The resource manager controls the service engagement on the basis of a priority information item.
