Title:
METHOD FOR DIAGNOSING THE OPERATION OF AN ACTIVE AIR FLOW REGULATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/203219
Kind Code:
A1
Abstract:
The present invention relates to an active air flow regulation system and a method for diagnosing the operation of an active air flow regulation system for a vehicle, comprising: an obstructing mechanical member; - a mechatronic system provided with a housing containing a magnet motor driven by a control circuit and coupled to a movement transformation for moving the obstructing mechanical member; - electronic communication lines for exchanging information with the DCU (8) of the vehicle or receiving commands from the DCU of the vehicle, which is characterised by comprising a series of steps consisting in: - storing, during an operating cycle of the active air flow regulation system, a numerical sequence S of data in a memory, the data being acquired by the control circuit inside the mechatronic system; - applying an algorithmic statistical analysis model to the numerical sequence of data stored in the memory in order to determine a singularity; - identifying a sporadic error associated with the singularity in order to provide information on the state of the active air flow regulation system.
