An agricultural production machine configured for determining optimized working parameters for the of the agricultural production machine is disclosed. The agricultural production machine has a driver assistance system and a sensor system and performs an agricultural task in a local context. The driver assistance system comprises a map control system that includes one or more maps to optimize work parameters of the process units of the agricultural production machine. A particular characteristic map describes a relationship between working parameters of the process unit and quality parameters using initial working points. When performing the agricultural task, the driver assistance system checks a local context to determine whether a context-related map is available and, if so, replace the basic map with the context-related map in order to determine optimized working parameters.
