Swivel drive for a hydraulic excavator

excavating machine
An automated software testbed for the simulation of electrical faults in the cable loom and their recognition by the control software was developed and built during the software development for a hydraulic excavator. This considerably reduced expenditure on tests for proving safety functions in the event of a fault.


  • Planning/setting up a software testbed
  • Creation of a residual model of the entire machine
  • Creation of test cases
  • Development of automated function and failure recognition tests
