Erweiterte Motormodellierung mit realistischem Jitter & Drive-by-Wire:
- OFF/ACC/ON/START Logik, Starten/Abwürgen
- Thermik (Kühlmittel/Öl), Öldruck ~ f(RPM)
- Startverhalten abhängig von Spannung & Öltemp
- Leistungsmodell via engine_power_kw + torque_peak_rpm
- Fahrerwunsch: throttle_pedal_pct (0..100) → Ziel-Leistungsanteil
* Drosselklappe (throttle_plate_pct) wird per PI-Regler geführt
* Mindestöffnung im Leerlauf, fast zu im Schubbetrieb
- Realistischer RPM-Jitter:
* bandbegrenztes Rauschen (1. Ordnung) mit Amplitude ~ f(RPM)
* kein Jitter unter einer Schwell-RPM oder wenn Motor aus
Outputs:
rpm, coolant_temp, oil_temp, oil_pressure
engine_available_torque_nm, engine_net_torque_nm
throttle_plate_pct (neu), throttle_pedal_pct (durchgereicht)
