Vehicle Dynamics and Control Systems

With the introduction of the Panamera, the fourth model line from Dr. Ing. h.c. F. Porsche AG, the team in Zuffenhausen has installed the world’s first start/stop system in a luxury claß car with an automatic transmis- sion, in this case the Porsche Doppelkupplung (PDK). In city driving, the sports car saves up to 1.5 l fuel per hundred kilometres in comparison to a manual transmißion. the developers explain the operating strategy, the control mechanisms and the system integration and describe how numerous components were modified to cope with the increased loads.
