Aus dem Vortrag von Magna: Die veränderte Rolle des Powertrains aus Sicht von Magna
Zusammenfassung
Neben der schieren Vielfalt von Varianten elektrifizierter Antriebe sind Antriebsentwickler mit Rahmenbedingungen konfrontiert, die sich jederzeit ändern können. Beispielsweise ist schwer abzusehen, inwieweit und wann die heutige Tank-to-Wheel-Bilanzierung in der EU
von CO2 zukünftig durch Well-to-Tank, Produktion oder Recycling ergänzt wird. Dazu kommen nicht minder herausfordernde technische Trends. Getrieben durch die Digitalisierung unterliegt die Antriebsentwicklung immer kürzeren Entwicklungszyklen. Die Funktionalität
verlagert sich in Richtung übergeordneter Software. Dies und die zunehmende Elektrifizierung bewirken, dass die Antriebshardware zunehmend der Systemfunktionalität folgen muss. Schließlich erwarten Autofahrer immer selbstverständlicher vernetzte und personalisierbare Zusatzfunktionen.
