Abstract

A simulator of an agricultural working machine has a computer unit coupled to a display unit and a control unit. The agricultural working machine to be simulated has adjustable working parts and control elements that implement adjustment of the working parts and a software module that is stored in the computer unit. The software module depicts a process model of crop-processing processes to be implemented by the agricultural working machine and depicts the machine behavior resulting from the crop-processing processes. The process model and the machine behavior are visualized in the display unit and can be edited by the control unit.

Claims

1. A simulator of an agricultural working machine, comprising

at least one computer unit coupled to a display unit and a control unit, where the agricultural working machine to be simulated comprises adjustable working parts and control elements that implement the adjustment of the working parts;

wherein a software module stored in the computer unit depicts a process model of crop-processing processes to be implemented by the agricultural working machine and machine behavior resulting from the crop-processing processes,

wherein the process model and the machine behavior are visualized in the display unit and are editable by the control unit,

wherein the display unit simulates a realistic user interface by providing a visualization of the control elements, the crop-processing processes and the machine behavior whereby the visualized control elements and a steering wheel are animated to be operated as would be control elements and a steering wheel actually positioned in the agricultural working machine.

2. The simulator of an agricultural working machine according to claim 1, wherein the process model accounts for crop-specific parameters, machine-specific parameters and environment-specific parameters and, based on said parameters and on stored characteristic curves, families of characteristic curves or both, determines quality parameters of the agricultural working machine to be simulated and visualizes the quality parameters as the machine behavior in the display unit.
