Improving functional safety in autonomous guided agricultural self propelled machines using Hardware-In-the-Loop (HIL) systems for software validation

摘要

Autonomous guided agricultural self-propelled machines are becoming more common in modern agriculture as well as the increased use of electronic solutions. In order to guarantee the effectiveness of Functional Safety functions software validation is also becoming more complex and critical during the product development. Hardware-In-the-Loop (HIL) systems not only improve software validation coverage, but also guarantee that neither operator nor machine will be put in a risky situation during the field validation phase. This article presents the case of HIL validation used in the development of a South American hybrid combine harvester.
