BMW Engine Simulation & Diagnostics

  • Developer
  • Automotive, control units, diagnostics
  • Test automation based on C / C++ / VB.Net COM and LabVIEW on Windows XP and Windows 2000
  • Automatic test environment for test cycles on diesel engine control units. Various sensors and actuators were driven directly or via COM servers using C/C++/C#. I implemented individual COM servers and wrote parts of the overall test automation. The COM servers basically simulate a subsystem that would otherwise be hard to integrate into the test setup. The goal was to test a software release of the engine control units in advance with relatively little effort.
