Abstract: A control system for determining a reference side area for a vehicle entity. The vehicle entity is a vehicle or a vehicle trailer and having a nominal vehicle entity side area. The reference side area is adapted to be multiplied with a side force coefficient for determining a side force parameter proportional to a wind side force load imparted on the vehicle entity and/or to be multiplied with a lift coefficient for determining a lift parameter proportional to a wind lift load imparted on the vehicle entity and/or to be combined with a drag coefficient for determining a drag load imparted on the vehicle entity. The vehicle entity comprises a load surface adapted to receive a material load such that at least a portion of the material load can be exposed to wind loads. The load surface being associated with a load surface area and a load surface length.

Abstract: A control system for a vehicle. The control system comprises a force determination controller adapted to determine external load characteristics of external loads that currently act or are predicted to act on the vehicle. The control system is adapted to determine a resulting force vector to be acting on the vehicle, using the external load characteristics, in order to obtain a requested vehicle operation behaviour. The control system is further adapted to issue control information to one or more motion support devices of the vehicle in order to control the one or more motion support devices so as to generate the resulting force vector on the vehicle. The control system further comprises a feedforward controller adapted to receive wind information representative of a wind currently acting or predicted to be acting on the vehicle.

Abstract: A computer-implement method of predicting a drag area (as function of air-attack angle) of a vehicle combination after hypothetically changing an exterior shape of the vehicle combination from a first exterior shape to a second exterior shape is provided. The method includes obtaining a first drag area function, obtaining a first projected area function, obtaining a second projected area function, and predicting a second drag area function based on a rescaling of the first drag area function by a ratio of the second projected area function to the first projected area function.

Abstract: A computer-implement method of estimating air drag for a vehicle combination is provided. The method includes detecting 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 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 a crosswind-sensitive air drag model for the vehicle combination.

Abstract: The invention relates to a computer-implemented method of controlling the cabin climate in a vehicle travelling on a road. A requested temperature value of a desired temperature for at least one part of the cabin is detected. An allowable temperature deviation from the requested temperature value is determined. Topographic data representative of the topography of an upcoming road segment is acquired. A flow creating device of an air-conditioning system of the vehicle is controlled based on the acquired topographic data so as to maintain the temperature within the allowable deviation. The invention also relates to a computer program, to a computer readable medium, to a control unit and to a vehicle.
