Testing Engine Control Software

To test the software of complex engine controls, entries to the fault memory of the electronic control unit (ECU) must be prevented. In addition, almost all control loops have to be closed to allow self-diagnostics. This is only possible by means of hardware-in-the-loop simulation. So BMW uses several dSPACE Simulators to test new software. The test systems have become a vital aid to putting new engine control software into operation at BMW.
