ARRANGEMENT AND METHOD FOR OPTIMIZING THE POSITION OF AT LEAST ONE AIR DEFLECTOR
First Claim
1. Arrangement for optimizing a position of at least one air deflector guiding an airflow around a vehicle during driving, comprising:
- at least one air deflector for guiding an airflow around the vehicleat least one actuator for moving the at least one air deflector between at least two positions; and
at least one controller for controlling each actuator and thereby the position of the air deflector in dependence on a control signal indicating an air resistance of the vehicle;
wherein the arrangement further comprises a vehicle driving control system for controlling at least a driving speed of the vehicle, wherein the arrangement is adapted to enable an optimization of the at least one air deflector, if the vehicle driving control system controls the speed of the vehicle.

Abstract
An arrangement and method are provided for optimizing a position of at least one air deflector guiding an airflow around the vehicle such as a truck or truck-trailer combination during driving. A 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, the speed of the vehicle is controlled by a vehicle driving control system for providing a constant speed of the vehicle during the optimization, and the position of the at least one air deflector is varied until the control signal indicates a minimized air resistance of the vehicle.
