Combining Real and Virtual Electronic Control Units in Hardware in the Loop Applications for Passenger Cars

Abstract

For the testing of modern electronic control unit (ECU) software, different test-platforms like Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) but also in vehicle testing are used. To ensure a realistic behavior of the software in SIL and HIL testing, models of the environment as well as residual bus simulation are required. A detailed representation of other controllers in the vehicle network that feeds into the residual bus simulation is needed to test complex functions of the software and to close distributed control loops. We present a novel approach, where a virtual ECU designed for SIL testing is reused to generate the input to the residual bus simulation. For export from the SIL tool and import into the HIL modelling environment, a C-Code functional mockup unit is used. To show the benefit of this approach, the setup is compared to an existing setup, which uses both a simplified model of an ECU or the real ECU. In addition, drawbacks of the presented approach are presented and the potential of other methods is discussed.
