Device for detecting intention to lock or unlock a motor vehicle door and associated method

A method for detecting intention to lock or unlock a door (P) of a vehicle, said method comprising the following steps:

• providing a detection device (D′) that includes
• a first capacitive sensor with 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 with 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′),
• the first electrode (EA) and the second electrode (EB) 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
• the microcontroller (60′) being configured to operate as:
• control means (MA) that controls said first capacitive sensor and generates a first approach and/or contact detection signal (SA), and
• control means (MB) that controls said second capacitive sensor and generates a second approach and/or contact detection signal (NB);
• and
• determining, via the microcontroller, whether there is a correlation between the first approach and/or contact detection signal (NA) and the second approach and/or contact detection signal (NB), such that:
• if there is a correlation, then there is confirmation of detection of intention to lock or unlock;
• and
• if not, there is no confirmation.
