Abstract: Disclosed is a device detecting intention to lock or unlock a vehicle door, including: a first capacitive sensor including a first electrode, detecting the approach and/or contact of a human body part in a predetermined region around the handle; a first sensor controller, generating a first approach and/or contact detection signal; a second capacitive sensor including a second electrode, detecting the approach of a human body part in the predetermined region, wherein: the first and second electrodes are each separate segments electrically connected to one another, the segments of the first electrode and of the second electrode are alternately juxtaposed; a second sensor controller generate a second approach and/or contact detection signal; a correlator to calculate a correlation value between the first signal and the second signal; and a confirmation unit comparing the correlation value with a predetermined value to detect intention to lock or unlock the door.

Abstract: A method for detecting actuation of a handle of a motor-vehicle opening panel-vehicle, including the steps of continuously generating the request to unlock signal, detecting an increase in the value of the request to unlock signal beyond a first predetermined detection threshold representative of the presence of a hand of a user on the handle, detecting a decrease in the value of the request to unlock signal below a second predetermined detection threshold representative of the user pulling on the handle, consecutively to the detection of the decrease in the value of the request to unlock signal below the second detection threshold, triggering a time counter, stopping the time counter at the end of a predetermined “confirmation time”, and validating the detection of a request to unlock the opening panel if the value of the request to unlock signal remained greater than a third predetermined threshold throughout the confirmation time.
