ETAS ASCMO – Accurate Prediction of Complex System Behavior: ETAS ASCMO facilitates the optimization and calibration of complex systems in virtual environments on the PC. The use of ETAS ASCMO significantly reduces the effort required for testing on real-world systems, e.g., at the test bench or in the vehicle. ETAS ASCMO uses a data-based model of high accuracy to describe system behavior. The model is based on a minimal number of measurements taken on the actual system.
