A reliable and secure activation of an access based on a detection of movement in a remote access system by providing a secure method for opening/closing of an access in hands-free access mode. The detection of movement relates to the displacement of a lower member of a user by a remote access system, this access system including at least two elements of detection which each emit a signal whose variations () are analyzed. The detection of a movement of a lower member is validated by the application of a double verification step according to parameters (dAsA, dAsB) of a criterion for identification (tA, tB; dAsA, dAsB) of a form of variation (F; A, B) of each signal () with a model form of the movement, and according to a criterion for simultaneity of detection of the forms of variation (F) identified on the two signals.

Method for opening/closing of a secure hands-free access by detection of movement of a lower member of a user

Method for communication between an electronic module and a sensor having a first branch, including a light source LED and a first switch, and a second branch including a second switch, supplied by a supply line, the module measuring modulations of intensity of current of the line. When the light source is turned on or in the process of turning on/turning off, the sensor causes i) modulation of the intensity of the current in the LED between a high state and a low state, ii) modulation of the intensity of the current in the second branch so that the intensity of the current is always in a higher state, and, in case of detection, iii) dispatches to the electronic module a modulation of the intensity of current in the second branch, when the intensity of current in the LED is in the low state.

Method of searching for a variation in capacitance of a capacitive sensor, includes a phase of searching for variation in capacitance and, when a capacitance variation has been detected, a phase of verifying the variation in capacitance. The search phase includes a recurrent step of searching for variation in capacitance including steps of measuring the duration of a first measurement sequence and determining, according to the measured duration, whether a first predefined detection criterion for variation in capacitance is verified. The verification phase includes steps of measuring the duration of a second measurement sequence and determining, according to the measured duration, whether a second predefined detection criterion for variation in capacitance is verified. The first measurement sequence has a reference duration less than that of the second measurement sequence, and the verification phase includes, when the second detection criterion is not verified, a step of updating the first detection criterion.
