Abstract
The present invention relates to a hands-free system (SYS) for accessing a motor vehicle (V). Said system includes: a control member (COM) arranged in the motor vehicle (V); a detection member (CAPT) arranged in a door handle (P) of the motor vehicle (V), said detecting member being connected to said control member (COM) and capable of measuring a signal (S) representing a hand (M) approaching; and a sensitivity level (SEN) for which a corresponding threshold value (TH) is defined. Said control member (COM) is capable of sending a hands-free query to the motor vehicle (V) when the measured signal (S) exceeds the threshold value (TH) corresponding to the sensitivity level (SEN). Said hands-free system (SYS) is characterized in that it includes at least two sensitivity levels (SEN1, SEN2), that is, a first high-sensitivity level (SEN1) and a second low-sensitivity level (SEN2), and in that the control member (COM) is also capable of changing the sensitivity level (SEN1, SEN2) of the hands-free system (SYS) in response to a predetermined sequence (SQ) of events.
