Problems solved by technology

This still leads to excessive fuel consumption and thus high running costs
[0012] Another major disadvantage of the known methods described above is that the interrogation process, or the manual adjustment of the air deflectors, and the constant check of the vehicle speed and road shape can lead to serious distractions for the driver, which can ultimately jeopardize safety

Embodiment Construction

[0038] Typically, a truck comprises a driver's cab and a storage compartment, in particular a trailer, wherein a certain space is left between the driver's cab and the trailer. The height and / or width of the trailer may differ from the height and / or width of the cab, resulting in less than optimal aerodynamics of the truck or truck-trailer combination. To reduce the vehicle's air resistance and save fuel, a roof deflector and side deflectors are mounted on the cab to reduce the trailer's frontal area for oncoming airflow and achieve a more streamlined and complete vehicle. Factors that may affect air resistance are primarily wind direction, wind speed relative to the vehicle, and certain geometric factors, namely: the height and width of the cab relative to the height and width of the trailer; and the distance between the trailer and the trailer. distance. Therefore, even a small angular change in the deflector setting can have a significant effect on the overall air resistan...

Abstract

The present invention discloses an arrangement and method for optimizing a position of at least one air deflector guiding an airflow around the vehicle, particularly of a truck or truck-trailer combination, during driving, wherein the position of the at least one air deflector is determined by an actuator which is controlled in response to a sensed control signal indicating the air resistance of the vehicle, wherein the speed of the vehicle is controlled by means of a vehicle driving control system for providing a constant speed of the vehicle during the optimization, and wherein the position of the at least one air deflector is varied until the control signal indicates a minimized air resistance of the vehicle.

Description

technical field [0001] The invention relates to a device and a method for optimizing the position of at least one air deflector for directing an airflow around a vehicle during driving, in particular around a truck or a truck-trailer combination wherein the position of the at least one air deflector is determined by an actuator controlled in response to a control signal indicative of the air resistance of the vehicle. Background technique [0002] When driving at high speeds, the air resistance of a vehicle, especially a truck or a truck-trailer combination, is one of the important factors affecting the fuel consumption of the vehicle. In particular, trucks or truck-trailer combinations with a cab having a different height and / or width than the storage compartment or trailer have a high air resistance during travel. [0003] A common measure to reduce air drag on a truck or truck-trailer combination is to use air deflectors that reduce the frontal area of ​​the trailer to i...
