    Abstract: The present invention concerns a method (PR) for detecting an identifier (Id) for starting a motor vehicle (V), said motor vehicle comprising a first antenna (A1) and said identifier (Id) comprising a second antenna (A2). The method (PR) is characterized in that it comprises: transmitting, by said first antenna (A1), a first Bluetooth Low Energy™ signal (Sg1) to said identifier (Id) at a nominal power (P1); measuring the power (P1′) of said corresponding signal (Sg1′) received by the second antenna (A2) of said identifier (Id); comparing said measured power (P1′) with a threshold power (Ps), said threshold power (Ps) corresponding to a threshold distance (ds) from said first antenna (A1) that is less than the radius (r1) of a circle (C1) inscribed within the passenger compartment (H) of the motor vehicle (V), said circle (C1) being centered on said first antenna (A1); authorizing the starting of the motor vehicle (V) if the measured power (P1′) is greater than or equal to said threshold power (Ps).

    Abstract: The invention relates to a method for controlling access to at least one function of a motor vehicle (10), comprising: —an action step during which an electronic control unit (11) on board the motor vehicle detects an interaction of a user with the motor vehicle, —a verification step during which the electronic control unit verifies that the user is authorized to access said function, and —an authorization step during which the electronic control unit authorises access to said function. According to the invention, said verification step comprises sending of a query message by said electronic control unit to a mobile terminal (20) carried by the user or by a person accompanying the user, and said authorisation step is only implemented if, in response to the query message, the electronic control unit receives an access-right validation message from the mobile terminal.
