Abstract:
1. A method for characterizing, by way of at least one primary antenna ( 13 , 31 ) on board a motor vehicle ( 10 ), a mobile device ( 20 ) of indeterminate type comprising a secondary antenna ( 21 ) of indeterminate size, approaching said motor vehicle ( 10 ) in an indeterminate approach mode, said primary antenna ( 13 , 31 ) being intended to communicate with the secondary antenna ( 21 ) of said mobile device ( 20 ), and generating a voltage (V) across its terminals, said voltage (V) being linked to an on-board system ( 11 ) of the motor vehicle ( 10 ), the method comprising the following steps: step 1: measuring by the on-board system ( step 2: computing by the on-board system ( step 3: comparing by the on-board system ( step 4: determining whether the mobile device is of dielectric type or metallic type, step 5: once the type of the mobile device has been characterized, determining whether the mobile device is in static approach mode or dynamic approach mode,
