[0004] If the conditions during the adjustment process are already abnormal conditions, e.g. the air guide has been affected by gusts, displacement air from oncoming vehicles or equivalent, the optimum conditions for the lowest possible air resistance have been determined correspondingly Parameters can be wrong so that the air guiding device is adjusted to non-optimal conditions, which leads to increased fuel consumption

Embodiment Construction
[0024] In this document, the term "link" refers to a communication link, which may be a physical line such as an optical communication line or a non-physical line such as a wireless connection such as a radio link or microwave link. Also, the term "for securing an acceptable function" refers to achieving a desired function of the ceiling-mounted air guide device in terms of air resistance reduction in a reliable manner.
[0025] Figure 1a schematically shows a side view of a motor vehicle equipped with an air guiding device 10 , 20 , 30 according to an embodiment of the invention, and Figure 1b Schematically shows Figure 1a Floor plan of the vehicle in . The vehicle comprises a system I according to the invention for ensuring acceptable functioning of an air guiding device.

The present invention relates to a method to ensure the acceptable function of an air guiding device at a vehicle. The vehicle has a longitudinal axis parallel to the normal direction of travel of the vehicle, and which vehicle comprises a first vehicle body and a second vehicle body arranged behind the first vehicle body and extending upwards and / or sideways beyond the first vehicle body. The air guiding device is supported by means of the said first vehicle body and can be adjusted relative to the said longitudinal axis for the purpose of reducing air resistance. The air guiding device can be adjusted by means of an adjuster, whereby a parameter that corresponds to the adjustment force required is determined during adjustment of the air guiding device. The method is characterised by the steps: to determine, during a first adjustment process, a time course (R1, R1 a) of the said parameter and, under essentially corresponding conditions with respect to the driving of the vehicle during at least one further adjustment process to determine a time course (R2, R3, R2a, R3a) of the said parameter, and to compare the time course of the said parameter during the first adjustment process and during the said, at least one, further adjustment process, whereby deviations between the time courses of the said parameter determined in this way are used as a basis to assess the reliability of the time courses. The present invention relates to a system to ensure acceptable function of an air guiding device at a vehicle, and a motor vehicle comprising such a system. The present invention relates also to a computer program and a computer program product.
Description
technical field [0001] The invention relates to a method for ensuring acceptable functionality of an air guiding device at a vehicle according to the preamble of claim 1 . The invention relates to a system for ensuring acceptable functioning of an air guiding device at a vehicle. The invention also relates to motor vehicles. The invention also relates to computer programs and computer program products. Background technique [0002] Vehicles displace air as they move, and air resistance affects a vehicle's fuel consumption. For a truck having a front body and a rear body coupled behind the front body and extending upwardly and / or laterally beyond the front body, for a vehicle such as a truck, the front surface of the extended portion of the rear body would cause significant air resistance . In order to reduce the air resistance for such vehicles, air guides supported by means of the front bodywork are used. Such a rear bodywork, which can be changed frequently and can be...
