Abstract
Temperature control of an interior of a motor vehicle having an electrical drive is carried out by a heat pump arrangement having a heating temperature region and a low temperature region, wherein the heating temperature region includes at least one interior heat exchanger thermally coupled to the interior and the low temperature region includes at least one of an exterior heat exchanger and a heat exchanger disposed on a component of the electrical drive. When the interior of the motor vehicle is be temperature-controlled, heat energy from the heating temperature region of the heat pump arrangement is delivered to the interior of the vehicle, and the operating point of the electrical drive is altered such that the generation of thermal losses is controlled in at least one electrical component of the electrical drive, such that the temperature of the low temperature region in the stationary or quasi-stationary operation is controlled at a level so as to ensure that the heat pump arrangement can provide the heating energy.
