1. A method for detecting the opening of the openable sections of a motor vehicle by a detection device, the detection device comprising at least two ultra high frequency communication modules, each located on a different openable section and connected to an electronic computer, the detection device allowing “hands-free” access to the vehicle, the method being characterized in that, said modules being capable of identifying one another, an opening angle of a first openable section is determined on the basis of:
a) a first distance between a point of rotation of the first openable section on which a first communication module is located and a position of a second module (20) when the two openable sections associated with said two modules are closed,
b) a second distance between a point of rotation of the first openable section and a position of the first module on said openable section,
c) a distance between said modules when the two openable sections associated with the two modules are closed, and
d) a distance between said modules, said distance being determined by a time of flight of the ultra-high-frequency radiation exchanged between the two modules.
