Clever Climate Control in the Open Air
Too cold? Too warm? Humans can be sensitive to temperature fluctuation. Now Porsche’s automatic climate control system in the latest generation of Porsche 911 intelligently ensures a sense of comfort.
The challenge: while the interior temperature sensor is a central control variable in a closed vehicle, many additional influences are added when driving in the open air. This is why the new cabriolet control system slowly suppresses this sensor as the soft-top is opened. The complex automatic climate control system now processes around 350 signals in half-second intervals in coordination with twenty external and twenty internal interfaces. The interfaces relevant to the climate control unit include the control units for the engine, soft-top, doors, and seats. The climate control system uses this data stream to continuously calculate the optimum air temperature, air outlet volume, and air distribution in the open-top interior.
During top-down excursions in the winter, the Porsche system overrides the conventional comfort formula of “warm feet, cool head.” Instead, the automatic climate control system distributes more warm air via the center air vents for the driver and front passenger.
All set for open-top season – the new 911 Cabriolet
