Abstract
A method for initiating a defrosting process of a heat exchanger of a heat pump of a motor vehicle, wherein the heat exchanger and a coolant heat exchanger of a cooling circuit of the motor vehicle are arranged in a common air path, involves determining a coolant outlet temperature of a coolant from the coolant heat exchanger, determining a state of icing of the heat exchanger using the coolant outlet temperature, and initiating a defrosting process of the heat exchanger if icing of the heat exchanger is determined.
