Patent number: 11890913Abstract: A vehicle is provided with a temperature-control system for controlling the temperature of an interior of the vehicle. The system has a temperature-control medium, preferably a liquid temperature-control medium, guided in a temperature-control circuit. The temperature-control system is operatively connectable or operatively connected to a source temperature-control system such that the temperature-control medium guided in the temperature-control circuit of the temperature-control system may be thermally influenced by the source temperature-control system. The temperature-control circuit also is operatively connectable or operatively connected to at least one interior temperature-control system such that the temperature of the interior of the vehicle may be modified by the temperature-control medium in the temperature-control circuit.Type: GrantFiled: January 21, 2020Date of Patent: February 6, 2024Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Thomas Rotenburg, Christian Rosskopf, Peter Satzger, Stefan Wiedemann
