Highly efficient development of powertrain systems using 1D Real-Time Engine Model 2023-32-0154

With the promotion of electrification of powertrains, development using the simulation model is being promoted to achieve highly efficient development of the powertrains. Since the hybrid powertrain includes many subsystems, the complexity of the development process bloats the development scale. To proceed with large-scale development efficiently, it is necessary to utilize simulation. Furthermore, to maximize efficiency, improvement in development speed is required. In this study, we selected the real-time technology for 1D engine model that is suitable for the concurrent development aiming at increasing the development speed. The real-time technology achieved a high prediction accuracy, a lower modeling workload, and reliable real-time computation speed. And as a practical application of this technology, we conducted collaborative development of engine and transmission using the real-time engine model.
