In parallel to increasing the application of intelligent, automated and unmanned Construction Equipment, functional safety regulation for Safety Related Parts of Control System(SRP/CS) has been reinforced in Europe, etc. In this paper, we will briefly review the methods of hardware failure rate estimation, which is a basis for functional safety requirements based on ISO 13849, etc. Instead of actual controllers used in the field, a virtual controller with multiple inputs and outputs will be considered here, also a virtual bill of materials(BOM) consisted with passive elements and active elements will be listed. Based on these database, We will estimate failure rate of each components based on SN 29500, and then hardware FMEA will be performed for this virtual controller. By doing this, We will show how to estimate hardware failure rate in accordance with ISO 13849, etc.
