Echtzeit-14-DOF-Mehrkörper-Fahrzeugdynamik & Reifen-Fahrbahn-Reibung

AutomobileSim liefert deterministische, physikalische Simulations-Engines für Fahrwerks-ECUs. Mit 1-kHz-Lösungsverfahren für 14 Freiheitsgrade bildet es Lasttransfers, Sturzwinkeländerungen und Aquaplaning präzise ab.

Schließen der Sim-to-Real-Lücke für elektronische Stabilitäts- und Traktionskontrolle

Moderne Software-Defined Vehicles erfordern mikrosekundengenaue physikalische Modelle für die HIL-Validierung von ESP und Torque Vectoring. AutomobileSim erfasst nichtlineare Elastokinematik und temperaturbedingte Reifendruckänderungen für sichere Fahrwerksabstimmungen.
