  "textContent": "A computer-implement method (100) of estimating air drag for a vehicle combination is provided. The method includes detecting (S101) a change of an exterior shape of the vehicle combination to a new exterior shape. The method includes, in response to detecting such a change, and based on one or more images of the vehicle combination captured after the change, estimating (si02) a projected area function indicating a dependence of a projected frontal area of the vehicle combination having the new exterior shape on air-attack angle. The method includes using the estimated projected area function to update (S103) a crosswind-sensitive air drag model for the vehicle combination. A corresponding device for performing the method, a vehicle/vehicle combination, and computer program and computer program product are also provided.",
