[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.
[0026] The vehicle 1 has a longitudinal axis X parallel to the normal direction of vehicle travel. The vehicle includes a first vehicle body 2 (front vehicle body) and a second vehicle body 4 (rear ...

The invention relates to a method for ensuring acceptable functioning of an air guiding device at a vehicle. The vehicle has a longitudinal axis parallel to the general direction of travel of the vehicle, and the vehicle includes a first body and a second body disposed behind the first body and extending upwardly and / or laterally beyond the first body . An air guiding device is supported by means of the first vehicle body and is adjustable relative to the longitudinal axis for the purpose of reducing air resistance. The air guiding device can be adjusted by means of a regulator, whereby parameters corresponding to the required adjusting force during the adjustment of the air guiding device are determined. The method is characterized by the steps of determining the time course (R1, R1a) of said parameter during a first adjustment process and, under substantially corresponding conditions with respect to the driving of the vehicle, during at least one further adjustment process the time course of said parameter (R2, R3, R2a, R3a), and comparing the time course of said parameter during the first adjustment process and during said at least one further adjustment process, thereby determining in this way The deviation between the time courses of the parameters is used as the basis for assessing the reliability of the time courses. The invention relates to a system for ensuring acceptable functioning of an air guiding device at a vehicle and a motor vehicle comprising said system. The invention also relates to computer programs and computer program products.
Description
technical field [0001] The invention relates to a method for ensuring acceptable functioning of an air guiding device at a vehicle. 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 of different dimensions, requires that ...
