METHOD FOR DETERMINING SPURIOUS CONTACTS ON A MOTOR VEHICLE DOOR HANDLE CONTACT DETECTION SENSOR

摘要

Method for determining spurious contacts on a motor vehicle (1) door (2) handle (3) contact detection sensor (4), said detection sensor (4) defining a locking control zone (L) and being connected to a locking and unlocking onboard electronic system (6), said method involving the following steps: a) detecting contact on the locking zone (L) when, for a locking engagement time (t1, t2), the number of charge transfers (N) of the detection sensor (4) is lower than a threshold number of charge transfers (Nth), characterized in that the method further comprises the following steps: b) evaluating the number of charge transfers (ND'), from the moment (tD' MIN) of the measured minimum value of the number of charge transfers and for an evaluation time (t) so as to distinguish between detections of contact made by the user and spurious contact detections, c) if the contact detections are spurious contact detections, adapting the threshold number of charge transfers (ND'th) so as to be able to detect any further contact from the user in the locking zone (L) in the presence of spurious contacts.
