Abstract
A flap to be identified is caused to move over the whole of its angular range of travel. The number of motor steps is counted during this movement, and the number of steps counted is compared with at least one pre-recorded information item corresponding to a particular flap or type of flap. The method is applicable to the checking of the correct fitting of actuator housings in an air-conditioning installation, or to the allocation of addresses to actuators connected to an information bus.
Claims5
Method of identifying a flap actuator with a stepper motor in a motor-vehicle air-conditioning installation, characterised in that it comprises the stages which consist in:
- causing the flap to move over the whole of its angular range of travel,
- counting the number of motor steps during this movement, and
- comparing the number of steps counted with at least one item of pre-recorded information corresponding to a particular flap or type of flap.
