Claim:
1. A method for detecting the actuation of a handle of a motor vehicle door, said handle including an unlocking presence detection device generating an unlocking request signal, a locking electrode having a capacitance across terminals thereof, an approach detection sensor connected to the locking electrode, and a microcontroller connected electrically to the approach detection sensor and to the unlocking presence detection device, said method comprising the following steps: Step 1: continuously measuring the unlocking request signal and a variation of the capacitance; Step 2: determining, during a first predetermined period, whether or not the unlocking request signal is representative of an unlocking request, and determining, during a second predetermined period following the first predetermined period, whether or not the variation of the capacitance is below a threshold; Step 3: detecting the actuation of the handle when the unlocking request signal is determined to be representative of the unlocking request during the first predetermined period and the variation of the capacitance is determined to be below the threshold during the second predetermined period; and Step 4: repeating Steps 1 and 2 when one or more of the unlocking request signal is not determined to be representative of the unlocking request during the first predetermined period, and the variation of the capacitance is not determined to be below the threshold during the second predetermined period.
