The method involves attributing, during an allocation, a set of sub-radio frequency channels in a frequency band so that each operating function of a hands-free access and/or cranking system can be assigned to at least a sub-radio frequency channel. The at...

The device has an inductive antenna (1) connected with a signal generator (5). A conductive cable (2) is coupled with the antenna along the entire contour of the antenna such that the cable presents inductive coupling with the inductive antenna. The cable ...

The procedure involves placing a memory in an initial state, when one user (9) quits a vehicle (1) by opening a door (5). Identifiers (6a, 6b) of another user (6, 6) remaining at an interior of the vehicle are detected and updated in the memory, when the d...

The process involves transmitting a code with two successive sequences of definite distinct powers to a portable device. The device receives a signal with an indication representing the extraction of low power sequences. The device emits the signal to a fi...
