1. A method for controlling a flow from a source of pressurized air to an air bag of a pneumatic suspension arrangement in a vehicle, the method comprising:
obtaining a set of vehicle condition signals comprising at least two vehicle condition signals, each vehicle condition signal being indicative of an individual current condition associated with said vehicle,
on the basis of said set of vehicle condition signals, determining whether or not there is a need to supply the air bag with air from the source of pressurized air, and
in response to determining that there is not a need to supply the air bag with air from the source of pressurized air, preventing pressurized air to be fed from said source of pressurized air to said air bag,
wherein determining whether or not there is a need to supply the air bag with air from the source of pressurized air comprises using a predetermined vehicle dynamics model to predict an air consumption based on the set of vehicle condition signals, and wherein preventing the pressurized air to be fed from said source of pressurized air to said air bag is performed when the predicted air consumption exceeds a threshold.
