1. A computer-implemented method of controlling the cabin climate in a vehicle travelling on a road, the method comprising:
detecting a requested temperature value of a desired temperature for at least one part of the cabin,
determining an allowable temperature deviation from the requested temperature value,
acquiring topographic data representative of the topography of an upcoming road segment,
controlling a flow creating device of an air-conditioning system of the vehicle based on the acquired topographic data so as to maintain the temperature within the allowable deviation,
predicting, based on the acquired topographic data, a propulsion power that will be needed in an upcoming road segment,
controlling the flow creating device based on that prediction,
determining, based on said prediction, that the flow creating device will be shut off during at least a part of the upcoming road segment, and
temporarily increasing the powering of the flow creating device before shutting it off.
