1. A device (D′) for detecting intention to lock or unlock a door (P) of a vehicle, said device (D′) comprising at least:
a first capacitive sensor comprising a first electrode (EA), capable of detecting the approach and/or contact of a human body part in a predetermined region (Z2) around the handle (10′);
a second capacitive sensor comprising a second electrode (EB), capable of detecting the approach and/or contact of a human body part in the predetermined region (Z2) around the handle (10′); and
a microcontroller (60′),
wherein the first electrode (EA) and the second electrode (EB) are each formed as separate segments that are electrically connected to one another, and said segments of the first electrode (EA) and of the second electrode (EB) being alternately juxtaposed, and
wherein the microcontroller (60′) is configured to operate as:
control means (MA) that controls said first capacitive sensor and generates a first approach and/or contact detection signal (NA),
control means (MB) that controls said second capacitive sensor and generates a second approach and/or contact detection signal (NB),
correlation means (MC) that calculates a correlation value between the first approach and/or contact detection signal (NA) and the second approach and/or contact detection signal (NB), and
confirmation means (MD) that compares said correlation value with a predetermined value in order to detect intention to lock or unlock the door (10′).
