Method for detecting the actuation of a motor vehicle door handle

A method for detecting the actuation of a handle (10) of a motor vehicle door (20), said handle (10) comprising:

• an unlocking presence detection device (50), generating an unlocking request signal,
• a locking electrode (60), having a capacitance across its terminals,
• an approach detection sensor (30) connected to the locking electrode (60), and
• a microcontroller (40, 40′) connected electrically to the approach detection sensor (30) and to the unlocking presence detection device (50),
• said method comprising the following steps:
• Step 1:
• continuously measuring the unlocking request signal (S) and a variation of the capacitance (ΔCV),
• Step 2:
• if, during a first predetermined period (t1), the unlocking request signal (S) is representative of an unlocking request, and if, during a second predetermined period (t2), following the first predetermined period (t1), the variation of the capacitance (ΔCV) is below a threshold (S2),
• Step 3:
• detection of the actuation of the handle (10) is validated,
• otherwise
• Step 4:
• repetition of steps 1 to 3.
