Abstract: The present application relates to a method and a system for operation of an air guide or deflection member of a vehicle. The method comprising; providing an air guiding or deflecting member, movably attached to the vehicle, providing an electrically drivable actuator, driving the actuator to adjust an orientation of the member relative to the vehicle, measuring a current of the actuator, determining the current derivative value, and determining a desired orientation of the member based on the current derivative value. The system comprising an air guiding or deflecting member, an electrically drivable actuator, and a controller. The controller is configured to measure a current of the actuator, determine a current derivative value, and determine a desired orientation of the member based on the current derivative value. This arrangement enables adjustment of the member's position into an optimal orientation without connection or communication with other systems of the vehicle.

Abstract: Method for optimizing a position of an air deflector (3, 4) guiding an airflow around a ground automotive vehicle during driving, comprising sensing a parameter of the electric actuator (30) for moving the air deflector (3, 4) from the first to the second position (p1; p2) and registering a plurality of signal amplitudes of the sensed parameter (101). The method further comprises a step of c1) in a time domain, identifying a portion of consecutive registered signal amplitudes, and identifying a position corresponding to a signal amplitude peak within the identified portion with a largest deviation from the first or second threshold value (102a), or as an alternative to c1), in a step c2) in a frequency domain, identifying center frequencies of pulses corresponding to registered signal amplitudes, and identifying a position corresponding to an identified center frequency of a pulse with a largest deviation from a frequency value (102b). Thereafter the air deflector (3, 4) is moved to the identified position (103).
