Abstract
A method and a device are presented for power distribution in a motor vehicle having at least one battery and at least one generator. In this case a hierarchical control structure is used which has a higher-level component and a component on a lower level for the control of the at least one generator and the at least one battery. Between the higher-level and the lower-level components, specified interfaces with specified communication relations are provided. Communication relations are specified as instructions which are to be executed by the components to which they are addressed. Requests should be met by the components to which they are addressed, and queries are answered by the queried components. The power or voltage is set between the component of the at least one generator and the higher-level component as an instruction. The potential for power production of the generator is to be transmitted as a query, and the electrical power potential of the battery is to be transmitted between the component of the at least one battery and the higher-level component as a query.
