自走式收割机如联合收割机具有多个作业单位，用于处理从田间采摘的作物，驾驶员辅助系统，用于传感器支撑的作业单位的控制，用于检测环境信息和空间区域的环境传感器系统 适用性位于收获机的环境中。 驾驶员辅助系统具有用于存储数据的存储器和用于处理数据的计算单元，包括存储在存储器中的数据。 收集机的至少一部分的功能系统模型存储在存储器中。 计算单元作为基于系统模型的特征控制，并自主地确定至少一个工作单元的机器参数，并将其指定给特定的工作单元。

The invention relates to a self-propelled harvesting machine, especially a combine harvester, with several working units (1, 2, 6, 7) for processing the received from a field crop and with a driver assistance system (10) for sensor-based control of the working members (1, 2, 6, 7 ), wherein the driver assistance system (10) comprises a memory (11) for depositing data, and a computing device (12) for processing the in the memory (11) stored data, wherein a surroundings sensor system (14) for detecting at least one the harvesting process-influencing environment information located with an around the harvester, territorial scope (15-18) is provided. It is proposed that in the memory (11) a functional system model (11b) is at least stored a part of the harvesting machine for that the computing device (12) based on the system model (11b) operates as a characteristic field control and machine parameters of at least one working member (1, 2, 6, 7), in particular autonomously determined and the respective working member (1, 2, 6, 7) predetermines and that for the determination of the machine parameters, the computing device (12) the system model (11b) defined in dependence on at least one environment information, or modifies and / or the computing device (12) of a control map based on at least one environment information control circuit is superimposed.
