    BACKGROUND Vehicles in motion displace air and air resistance affects the fuel consumption of vehicles. In vehicles such as trucks with a front vehicle body and a rear vehicle body connected behind the front vehicle body which extends upwards and / or laterally beyond the front vehicle body, the front surface of extending portions of the rear vehicle body will cause a significant air resistance. In order to reduce the air resistance of such a vehicle, an air deflector device supported by the front vehicle body is used. Such a rear vehicle body is often replaceable and the dimensions can vary, which for optimal reduction of the air resistance requires an adjustable air deflector device.
    WO2013-117539 discloses an air deflector device for such a vehicle where the air deflector device is adjustable by means of stall means in the form of an electric motor and wherein a parameter corresponding to the required stall force is sensed when disassembling the air deflector device. The air deflector device is formed between a first layer and a second layer in a formation process, a so-called sweep, and then by means of a control unit is set into the layer where the value of the parameter is 2 as the lowest, which corresponds to the minimum air resistance below -lard. This automatically enables correct installation of the roof air deflector device.
    If the conditions during the installation process were different, for example that the air deflector device was affected by gusts of wind, compressed air from 5-vehicle vehicles or equivalent, the determined parameter corresponding to the optimum condition for minimum air resistance may be incorrect so that the deflector device is installed in a non-optimal condition. 1610 OBJECT OF THE INVENTION An object of the present invention is to provide a method and a system for determining the operating status of an air deflector device of a vehicle which facilitates the parking.

According to one embodiment of the method, the step of adapting said interpretation comprises determining a further course of said parameter under substantially corresponding conditions regarding the performance of the vehicle including subsequent reliability assessment. This provides a way of securely securing the function, whereby the securing of satisfactory function of the roof air deflector device is further improved, whereby the risk of incorrect installation of the deflector device is minimized so that fuel consumption due to air resistance can be minimized.
    According to one embodiment of the method, the step of adapting said interpretation involves correcting the thus determined course of said parameter on the basis of said determined pressure influence during the pretreatment process. There are further additional pretreatment processes and subsequent reliability assessment which further reduces the process.
    According to an embodiment of the method, said staging takes place at a standstill or at a low speed.

Respective air deflector devices 10, 20, 30 hereby comprise stall means for positioning air deflectors 12, 22, 32. Stall means are described in 9 in connection with Fig. 5. Said stall means can be constituted by any suitable stall means for deflecting an air deflector device. Said stall means according to an embodiment comprise an electric motor. Said stall means alternatively comprise a pneumatic or hydraulic motor.
    The vehicle comprises means 120 for continuously determining the pressure effect of air entering the vehicle in its direction of travel. The means 120 for continuously determining the pressure effect of air entering the vehicle in its direction of travel comprises, according to a variant, the vehicle air supply.
    Figs. 2a-c schematically illustrate an air deflector device 10 arranged in a motor vehicle in different layers where the flow of air A directed by means of the air deflector device 10 is illustrated for the different layers. The vehicle is according to a variant of the vehicle 1 illustrated in Figs. 1a-b and consequently has a first vehicle body 2 and a second vehicle body 4 which extends upwards and / or laterally beyond the first vehicle body 2.
    Fig. 2a illustrates a layer where the rear end of the air deflector 12 is substantially higher than the height of the rear vehicle body 4, Fig. 2b where the rear end of the air deflector 12 is substantially lower than the height of the rear vehicle body 4, and Fig. 2c where the rear end of the air deflector 12 is correctly installed relative to the rear vehicle body 4. The air deflector device illustrated has as a roof air deflector device 10 with roof air deflector 12. The deflector device could also be the side air deflector device 20 or the side air deflector device 30.
    When driving, the vehicle will again be exposed to air load, where the air load depends on the angle of the air deflector 12 relative to the longitudinal axis X parallel to the vehicle's normal direction of travel, and the layer of the air deflector 12 relative to the rear vehicle body 4. The air load due to air flowing towards the surface has the air deflector increases the larger the angle relative to the axis X is. Air flowing past creates a reduced air pressure above the roof air deflector and consequently a lifting force acting on the air deflector 12.
    The air deflector creates a space C between the first vehicle body 2 and the air deflector 12.
    In Fig. 2a, when the air deflector of the air deflector device 10 is in a position such that the rear end of the roof air deflector 12 is substantially higher than the height of the rear vehicle body, an overpressure and a reaction force F1 will be created.

    In Fig. 2c, when the air deflector of the air deflector device 10 is in a position so that the rear end of the roof air deflector 12 substantially corresponds to the height of the rear vehicle body, air will flow evenly over the air deflector 12 and further over the other vehicle body 4. In this layer a reaction force F3 is directed against the air deflector from the outside in accordance with the reaction force F1 in the case of Fig. 2a and a counter-directional reaction force F4 directed from the inside in accordance with the reaction force F2 in the case in Fig. 2b to substantially take each other out.
    Fig. 2d schematically illustrates the spirit and stackability of the ceiling air deflector device 10 in Figs. 2a-c. The air deflector device illustrated has as a ceiling air deflector device 10 with ceiling air deflector 12. The air deflector device could also constitute the side air deflector device 20 or the side air deflector device 30.
    The air deflector device 10 is configurable in a configuration process between a first layer P1 and a second layer P2. The air deflector 10 is consequently adjustable between the first layer P1 in which the low air deflector has an angle relative to the longitudinal axis X parallel to the normal direction of travel of the vehicle which is relatively larger, and the second layer P2 in which the low air deflector has an angle relative to the longitudinal axis X is relatively smaller. The air deflector device 10 and the air deflector 12 are adjustable by means of stall means 40 between the first layer P1 and the second layer P2.
    FIG. 3a schematically illustrates a parameter corresponding to the required stable force as a function of layer for reference staging process and staging process 5 under -lard for an air deflector device according to the present invention. The air deflector device is constituted by a ceiling air deflector device 10 according to Fig. 2d.
    The stall force corresponds to the force required for the stall means 40 to displace the air deflector device 10 by turning the air deflector 12 between the layers P1 and P2. In a stable member in the form of an electric motor, the stable force corresponds, for example, to the required electric current.
    The dotted curve illustrates a reference formulation process arranged to take place at a standstill or at a low speed. By low speed is meant a speed at which air towards the vehicle does not substantially affect the stable force for displacing the air deflector.
    The reference forming process constitutes a forming process between the first layer P1 and the second layer P2 according to Fig. 2d. In this case, the reference production process takes place in the form of a sweep between the layer P1 and the layer P2. The reference formation process can also be called a reference sweep.
    The stable power increases with the team, ie. the angle relative to the longitudinal axis X 20 and has the height of the rear end of the air deflector 10 relative to the rear vehicle body 4.
    The solid curve illustrates a staging process during -lard, called a driving staging process, arranged to take place during driving, at a speed at which air towards the vehicle affects the stalling force to stifle the air deflector.
    The speed simulation process, like the reference simulation process, constitutes a simulation process between the first layer P1 and the second layer P2 according to Fig. 2d. In this case, the speed adjustment process takes place in the form of a sweep between the team P1 and the team P2. The course of the journey can also be called a journey. 12 The stable force is affected by the team at the air deflector, ie. the angle relative to the longitudinal axis X and has the angle of the rear end of the air deflector 10 relative to the rear vehicle body 4.
    Fig. 3b schematically illustrates a comparison between parameters for reference production process and production process under -lard according to Fig. 3a for different layers of the roof air converter device.
    By comparing the reference formulation process with the travel formulation process, it is possible to determine the layer at which the lowest air resistance during movement will be. This layer corresponds to the layer where the difference in stable force between stable force at different layers in the reference production process and stable force at the corresponding law at the speed control process, stable force, is the lowest. By ora this comparison, the mechanism of the air deflector is taken into account, ie. also that the air deflector can mechanically give more faithful / lighter in certain laws.
