Patent ID: 7750589

Claim:
A method for controlling the angular position [STP_POS] of a stopless rotatably movable member [ 1 ] of a stepper motor, the movable member [ 1 ] being able to interact with at least one fixed member [ 2 ] and a state of the fixed member [ 2 ] modifiable during the rotation of the movable member [ 1 ] according to the parameters [CAM_POS] previously defined according to the angular position [STP_POS] of the movable member [ 1 ], the method comprising the steps of: associating each angular position [STP_POS] of the movable member [ 1 ] with a state of the fixed member [ 2 ] to define the parameters [CAM_POS]; testing the correspondence [ 18 ] of the state of the fixed member [ 2 ] with the parameters [CAM_POS] of the predefined modifications, in a mode in which the position of the motor [STP_POS] is considered to be defined; and comparing the state of the fixed member [ 2 ] according to the parameters [CAM_POS] previously defined according to the position [STP_POS] of the movable member [ 1 ] to determine an output of the correspondence test [ 18 ].
