Abstract
The invention concerns a method for managing the load of a vehicle (C) of the type of that equipped with at least one module for transmitting data (110, 120, 130) through radiofrequency signals (F1, F2, F3) and one module for receiving (120, 220) data from the transmission module, said vehicle (C) and the different modules being disposed so that the load, once present, has an impact on the propagation of the radiofrequency signal, remarkable in that it comprises the following operation: detection of the variation of the spectral signature of the signal received (F2′) by the receiving module (120, 220), in order to detect variations, in particular corresponding to the presence and/or absence of a load (600). The invention also concerns the device enabling said method to be implemented.
