Procedure dynamic referencing a lighting device equipped with a stepping motor.

摘要

Method of referencing a projector assembly (100) comprising a movable headlight device (101) about an axis of rotation (105), a step (102) motor controlled by a control unit (103) and comprising a mechanical link (104) to ensure transmission of motion between the stepper motor (102) above and mobile projector device (101), characterized in that the method comprises at least the step of performing an operation referencing (708) the position of the movable headlight device (101), consisting of bringing the movable headlight device (101) into abutment against a reference position, when an angle of instantaneous position, defined between an instantaneous direction of the headlight device and the reference position, is less than an angle referenced activation predetermined.
