Example of the driver's view in the simulator
Abstract
The increasing automation and complexity of modern combine harvesters introduces complex high workloads on operators. Effective training will be essential in the future to ensure that operators can achieve the best harvest results, learn how to adjust the machine when automatic functions reach their limits, and ensure error-free operation of these expensive vehicles.
Existing simulators primarily simulate driving behaviour. However, this is not sufficient for highly automated mobile machinery such as combine harvesters - here, it is essential to realistically model process- and procedure-related functional sequences and states, as well as their interactions. The HySim project pursues this objective through the use of hardware-in-the-loop (HiL) technology, in which the actual machine control system and original controls are integrated into the simulation.
Objective
The goal is to develop a real-time simulator for mobile agricultural machinery - using the combine harvester as an example - that realistically models the machine’s behavior, including the actual control logic, assistance and automatic functions, and the original operator interfaces. The simulator is designed to operate realistically and simulate the operational processes of the combine harvester based on the respective operating parameters and crop characteristics.
Methods and Core Research Areas
The project is being implemented in collaboration between the project partners Hydrive Engineering GmbH and the Chair of Agricultural Systems Technology, focusing on the following areas:
- Requirement Analysis: Task analysis for combine harvester operators; definition of learning objectives and learning scenarios
- Process and Machine Modeling: Development of real-time-capable models for the technical processes (harvesting, threshing, separation) along the entire crop flow
- HiL Technology: Integration of the actual machine control system and original control elements into the simulation; implementation on the target hardware
- 3D Visualization: Editable interactive environment with machine-specific, configurable hardware setup
- Design and Testing: Design and manufacturing of the mobile simulator setup, commissioning, and testing of the learning scenarios
Expected Results
If the project proceeds successfully, a real-time simulator for combine harvesters will be available that integrates the actual machine controls and original operator interfaces. The simulator will enable realistic training for operators and can be used as a development tool for the usability of highly automated systems.
Project Funding
The project is funded by the Federal Ministry for Economic Affairs and Energy (BMWE) pursuant to a resolution of the German Bundestag as part of the Central Innovation Program for SMEs (ZIM) under grant number KK5017835GR3.
