Technology for Embedding Engine Models in ECU for Model-based Development

Article of Honda R&D Technical Review Vol.28 No.2


Consistency in the control subject model from the top level to the lower level of the V-process used in model-based development is an important factor when designing internal combustion engine control. For this reason, parameter calibration was used to provide relevance between the 1D engine model in the top level and the mean value engine model in the middle level so that the deviation is within a certain level. In addition, an environment was constructed for embedding the mean value engine model used by Hardware-in-the-Loop Simulation as is in an ECU. The model is described using a formula simulator and converted to C code. A tool was developed that automatically converts this code into C code for mounting in an ECU. The converted C code was actually operated using a CPU evaluation board, and was confirmed to operate in 10 ms or less, which is the calculation cycle for engine device control. This made it possible to link the models in the top and middle levels of model-based development and also enabled model mounting to an ECU in the lower level, which increased the reusability of V-process engine models.
