The goal of HSO in the A-IQ Ready project is to research and develope a holistic concept to derive a digital twin of the powertrain. This will be done by using artificial intelligence based on a novel approach that includes the fusion of the training algorithms and the real-world testbench. Thus targeting an enhanced data aquisition as well as a possibility to enable industrial partners to adapt the digital twin directly to their applications. This leads to a novel/greater system monitoring on a component as well as on a system level (e.g. health monitoring, energy consumption, remaining range, ...).
