System and method for controlling the service engagement in a data bus system

In a data bus system having a resource manager and various bus users using the data bus, at least one bus user providing services and other bus users using the provided services, wherein the resource manager stores information about the type of the available services provided by the bus users and information about the service-providing bus users, reserves a service from a providing bus user if the providing bus user's service can be used, and sends a response to a requesting bus user so that the requesting bus user can use the service from the providing bus user via the data bus, a method for controlling service engagements for the bus users on the data bus system comprising the acts of:

• providing the information about the provided services on the data bus by the bus users via a standard interface;
• making available to the resource manager via the standard interface a change in the provision of a service by a bus user;
• and
• controlling, via the resource manager, services which relate to the functions and the initialization of the bus users and of the data bus system.

In a data bus system having a resource manager, at least one bus user adapted to provide services and a plurality of bus users adapted to use the provided services, a method performed by the resource manager for controlling service engagements for bus users comprising the acts of:

• storing information about the available services provided by the bus users, the information being received on the data bus via a standard interface;
• receiving service requests from bus users via the data bus;
• ascertaining a service-providing bus user with the requested service in accordance with the stored information, and if the requested service is available, reserving the requested service from the service-providing bus user;
• monitoring, via the standard interface, changes in the provision of a service by a service-providing bus user;
• and
• controlling the service engagement on the basis of a priority information item.

• controlling services which relate to the functions and the initialization of the bus users and of the data bus system.

A data bus system comprising:

• a data bus;
• a plurality of bus users connected to the data bus, wherein at least one bus user is adapted to provide services and a plurality of other bus users are adapted to use the provided services;
• and
• a resource manager connected to the data bus, the resource manager including a memory and a standard interface and being adapted to maintain in the memory information about service-providing bus users,
• wherein the resource manager is further adapted to reserve a service from a service-providing bus user if the providing bus user's service can be used, and send a response to a requesting bus user, so that the requesting bus user can use the service from the providing bus user via the data bus, and
• wherein the resource manager is further adapted to control service engagements for bus users on the data bus system on the basis of priority information, the resource manager receiving through the standard interface the information about the provided services and monitoring via the standard interface changes in the provision of a service by a bus user.
