A self-propelled harvesting machine such as a combine harvester has multiple working units for processing crop picked up from a field, a driver assistance system for the sensor-supported control of the working units, an environmental sensor system for detecting environmental information and spatial areas of applicability located in the environment of the harvesting machine. The driver assistance system has a memory for storing data and a computing unit for processing data, including the data stored in the memory. A functional system model for at least one part of the harvesting machine is stored in the memory. The computing unit functions as a characteristic control on the basis of the system model and autonomously determines machine parameters of at least one working unit and specifies these to the particular working unit.
