Abstract:
A method is described to control an actuation profile of an electromechanical linear actuator device of an internal combustion engine designed to control the movement of a component; the internal combustion engine comprises a sensor, which faces the actuator device and is designed to detect the noise generated by the movement of the component; the method comprises the steps of acquiring, by means of the sensor, the intensity of a signal generated by the impact of the component against a limit stop; identifying a first listening window of the signal associated with said impact; calculating a noise index inside the listening window; comparing the noise index with a reference value; and controlling the actuation profile of the actuator device based on this comparison.

Claim (Index 1):
A method to control an actuation profile of an electromechanical linear actuator device ( 20 ) for an internal combustion engine (ICE); wherein the actuator device ( 20 ) is designed to control the movement of a movable armature ( 27 ) moving towards a first limit stop position defined by a fixed mechanical abutment ( 25 ) and vice versa; the internal combustion engine (ICE) comprises a sensor ( 31 ), which is arranged close to the actuator device ( 20 ) and is designed to detect the noise generated by the movement of the movable armature ( 27 ); the method comprises the steps of:\n acquiring, by means of the sensor ( 31 ), the intensity of a signal (S) generated by the impact of the movable armature ( 27 ) against the fixed mechanical abutment ( 25 ); identifying a first listening window (OW) in the signal (S) detected by the sensor ( 31 ); wherein the first listening window (OW) identifies the impact of the movable armature ( 27 ) against the fixed mechanical abutment ( 25 ); calculating a first noise index (IDRC) of the signal (S) detected by the sensor ( 31 ) inside the first listening window (OW); comparing the first noise index (IDRC) with at least one first reference value (I REF ); and changing a time (T ON-MAIN ) needed to reach the maximum value of the current absorbed by the actuator device ( 20 ) based on the comparison between the first noise index (IDRC i ) and the first reference value (I REF ), namely\n decreasing said time (T ON-MAIN ) needed to reach the maximum absorbed current value by a first value (\u0394t 2 ), in case the first noise index (IDRC) exceeds the respective first reference value (I REF ); or \n increasing said time (T ON-MAIN ) needed to reach the maximum absorbed current value by a second value (\u0394t 3 ), in case the first noise index (IDRC) is smaller than or equal to the respective first reference value (I REF ).
