Conclusies
1. Vrachtwagen aangedreven door een aandrijving, waarbij de genoemde aandrijving omvat: — een interne verbrandingsmotor; — een aandrijflijn, die zich uitstrekt vanuit de interne verbrandingsmotor en die is ingericht voor het overbrengen van aandrijfkoppel tussen de interne verbrandingsmotor en aangedreven wielen van de vrachtwagen, waarbij de aandrijflijn een elektrische motor omvat welke additioneel aandrijfkoppel verschaft tussen de interne verbrandingsmotor en aangedreven wielen van de vrachtwagen; en — een stop-start regelaar, die is ingericht voor het regelen van de aandrijflijn om een gevraagd wegrijdkoppel van de aandrijving te verschaffen, welke ten minste is gebaseerd op gemeten signalen vanuit een gaspedaal van de vrachtwagen, om de vrachtwagen te laten wegrijden vanuit stilstand naar beweging terwijl de interne verbrandingsmotor uitgeschakeld 1s; waarbij, terwijl de vrachtwagen in stilstand is, de stop-start regelaar is ingericht voor het uitvoeren van 1) in een eerste stap, het regelen van de aandrijflijn om te ontkoppelen van de interne verbrandingsmotor; en 1) in een tweede stap, het regelen van de elektrische motor in de aandrijflijn om het additionele aandrijfkoppel te verschaffen, om de vrachtwagen te laten wegrijden naar beweging zonder het aanzwengelen van de interne verbrandingsmotor, ongeacht een grootte van het gevraagde wegrijdkoppel; waarbij, wanneer de vrachtwagen in beweging is, de stop-start regelaar is ingericht voor het uitvoeren van iii) in een derde stap, het regelen van de aandrijflijn om te koppelen aan de interne verbrandingsmotor; en 1v) in een vierde stap, het regelen van de elektrische motor om het additionele aandrijfkoppel te verschaffen aan de interne verbrandingsmotor, om de interne verbrandingsmotor aan te zwengelen.
2. Vrachtwagen volgens conclusie 1, waarbij de aandrijflijn een koppeling omvat, welke 1s ingericht tussen de interne verbrandingsmotor en de elektrische motor voor het ontkoppelen van de aandrijflijn van de interne verbrandingsmotor in de eerste stap, en het koppelen van de aandrijflijn aan de interne verbrandingsmotor in de derde stap, en waarbij de stop-start regelaar is ingericht voor het overeenkomstig regelen van de koppeling.
3. Vrachtwagen volgens conclusie 2, waarbij, voorafgaand aan het regelen van de aandrijflijn om te koppelen aan de interne verbrandingsmotor in de derde stap, de stop-start regelaar is ingericht voor het regelen van de elektrische motor om een draaisnelheidsverschil tussen de elektrische motor en de interne verbrandingsmotor te verkleinen.
4. Vrachtwagen volgens conclusie 3, waarbij de stop-start regelaar is ingericht voor het gebruiken van de elektrische motor als een elektrische generator om kinetische energie van de aandrijflijn te converteren naar elektrische energie om het draaisnelheidsverschil tussen de elektrische motor en de interne verbrandingsmotor te verkleinen.
5. Vrachtwagen volgens conclusie 3, waarbij de stop-start regelaar is ingericht voor het regelen van de elektrische motor om het additionele aandrijfkoppel te verschaffen in een negatieve richting, tegengesteld aan een richting van het gevraagde aandrijfkoppel, om het draaisnelheidsverschil tussen de elektrische motor en de interne verbrandingsmotor te verkleinen.
6. Vrachtwagen volgens één van de voorgaande conclusies, waarbij de aandrijflijn een versnellingsbak omvat, welke is ingericht tussen de elektrische motor en de aangedreven wielen van de vrachtwagen, waarbij de stop-start regelaar is ingericht voor het regelen van de aandrijflijn om te koppelen aan de interne verbrandingsmotor in de derde stap, en voor het regelen van de elektrische motor om de interne verbrandingsmotor aan te zwengelen in de vierde stap, tijdens een schakelmoment terwijl aandrijfkoppel tussen de versnellingsbak en de aangedreven wielen van de vrachtwagen onderbroken is.
7. Vrachtwagen volgens conclusie 6, waarbij de stop-start regelaar is ingericht voor het regelen van de versnellingsbak om de vrachtwagen te laten wegrijden vanuit stilstand naar beweging in een geselecteerde versnelling van de versnellingsbak, in afhankelijkheid van een maximum additioneel aandrijfkoppel dat verschaft kan worden door de elektrische motor.
8. Vrachtwagen volgens conclusie 7, waarbij de stop-start regelaar is ingericht voor het regelen van de versnellingsbak om op te schakelen naar een hogere versnelling wanneer de vrachtwagen in beweging is,
in afhankelijkheid van een maximum draaisnelheid van de elektrische motor.
9. Vrachtwagen volgens één van de conclusies 6 — 8, waarbij na het regelen van de elektrische motor om de interne verbrandingsmotor aan te zwengelen in de vierde stap, de stop-start regelaar is ingericht voor het synchroniseren van de interne verbrandingsmotor met de versnellingsbak tijdens een schakelmoment, door het gebruiken van de elektrische motor als een elektrische generator om kinetische energie van de interne verbrandingsmotor te converteren naar elektrische energie, om een draaisnelheid van de interne verbrandingsmotor overeen te laten komen met een draaisnelheid van de versnellingsbak.
10. Vrachtwagen volgens één van de voorgaande conclusies, waarbij, na het regelen van de elektrische motor om de interne verbrandingsmotor aan te zwengelen in de vierde stap, de stop-start regelaar is ingericht voor het verschaffen van een power boost aan de vrachtwagen door het regelen van de elektrische motor en de interne verbrandingsmotor om gelijktijdig de wielen van de vrachtwagen aan te drijven in afhankelijkheid van een triggersignaal.
11. Vrachtwagen volgens conclusie 10, waarbij het gaspedaal een kickdownsensor omvat om het triggersignaal te verschaffen.
12. Vrachtwagen volgens één van de voorgaande conclusies, waarbij het gevraagde wegrijdkoppel additioneel is gebaseerd op een rijbaanhellingschatting.
13. Vrachtwagen volgens één van de voorgaande conclusies, waarbij het gevraagde wegrijdkoppel additioneel is gebaseerd op een bruto combinatiegewicht van de vrachtwagen.
