Method for identifying a signal source

A method for identifying a signal source in a vehicle, comprising:

• providing a set of identified signatures, wherein each signature is associated with a signal source;
• providing a plurality of sensors at different locations of the vehicle;
• creating at least one original recording of a signal detected by at least one of the sensors;
• storing parameters related to the conditions under which the at least one recording is created, wherein one of the parameters is related to speed of the vehicle;
• determining a spectrum of the signal;
• detecting at least one line emerging from background noise of the spectrum by using a predetermined emergence threshold;
• comparing the at least one line with at least one of the signatures in the set of identified signatures;
• corresponding at least one of the signatures to the at least one line;
• and
• identifying a source of the signal based on the corresponding step.
