Abstract
A method for initiating a defrosting process of a heat exchanger of a heat pump of a motor vehicle, wherein a fan is assigned to the heat exchanger, wherein the power consumption and/or the speed of the fan is monitored, a defrosting process is initiated when the power consumption and/or the speed exceeds and/or falls below a threshold value, and the threshold value is determined as a function of a parameter, wherein the parameter is an indicator of a current relative air speed of the ambient air in relation to the motor vehicle.
