    摘要: 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 characterised in that it comprises: - transmitting, by said first antenna (A1), a first Bluetooth Low Energy
    TM 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 centred on said first antenna (A1); - authorising the starting of the motor vehicle (V) if the measured power (P1') is greater than or equal to said threshold power (Ps).
