Some software functionality is very similar across several tractor types. For example residual speed control, which checks for unsafe situations arising if the tractor runs too fast. With the HIL system this functionality can be quickly and safely tested in all tractor types by switching parameter lists for the drivetrain model type, and by using an automated routine to flash ECUs.
Tractors that were previously tied up for software testing are now available for other tasks, such as fine-tuning the driving experience.
With Hardware-in-the-Loop, testing begins when the tractor is in the early stages of development. This accelerates the development process, allowing rapid changes to be made based on driver feedback, and improving the quality of the final product.
Simulink Real-Time together with Speedgoat hardware systems enabled AGCO Fendt to implement a complete testing solution, including LMS AMESim multiphysics simulation.
