Method and apparatus for operating a combine harvester

A method for operating a combine harvester having one or more work elements for harvesting a crop, comprising:

• determining, by an electronic driver assistance system of the combine harvester, a harvest setting for the crop and a machine configuration of the combine harvester;
• preselecting, by the electronic driver assistance system, a process control strategy from among a plurality of process control strategies stored in a memory of the electronic driver assistance system of the combine harvester, wherein the memory of the electronic driver assistance system further includes conditions associated with each of the plurality of process control strategies comprising at least one condition concerning the harvest setting and at least one condition concerning the machine configuration, wherein preselecting is based on the harvest setting and the machine configuration, wherein the preselection of the process control strategy comprises querying the conditions and preselecting the process control strategy only when the process control strategy fulfills at least both of the at least one condition concerning the harvest setting and the at least one condition concerning the machine configuration, and wherein each of the plurality of process control strategies is aimed at fulfillment of at least one harvesting quality criterion stored in the memory of the combine harvester;
• and
• automatically determining, by the electronic driver assistance system, at least one machine parameter for the one or more work elements of the combine harvester according to the preselected process control strategy and controlling the one or more work elements corresponding to the at least one machine parameter,
• wherein the harvest settings comprise at least a first grain type and a second grain type;
• wherein the machine configurations comprises at least a first machine configuration and a second machine configuration;
• wherein the plurality of process control strategies comprise at least four process control strategies each having a respective grain type condition selected from at least the first grain type and the second grain type and a respective machine configuration condition selected from at least the first machine configuration and the second machine configuration;
• and
• wherein the preselected process control strategy is preselected from the at least the four process control strategies, the preselected process control strategy fulfilling at least predefined requirements of the respective grain type condition and the respective machine configuration condition.
