The transition to zero emission and the demand for increasing levels of autonomy present many challenges for the development of modern heavy-duty vehicles (HDVs). Simulation plays a key role in accelerating the vehicle design stages, anticipating or preventing integration issues, and gaining competitive advantages.
In collaboration with MathWorks, MAN Truck & Bus has developed FASIMAN, a modular simulation tool based on Simulink for longitudinal dynamics, powertrain concept evaluation, energy consumption and range estimation. It uses energy management strategies and virtual testing of ECU functionalities and drivetrain calibration to support ADAS development and emission activities. FASIMAN’s modular approach enables it to model propulsion and vehicle configurations that are relevant for HDVs, including ICE, BEV, and FC.
In this presentation, see an overview of FASIMAN’s modular architecture and main features, including distinction between physical models and controls, bus system modeling, ECU integration (MIL), database connectivity, big data usage for load cycle derivation, and cosimulation.
We’ll also briefly present a fuel cell truck simulation for evaluation and design of the drivetrain concept, cooling concept, and supporting the control function development.
