Abstract (en)

Described herein is a method for generating and propagating, in a vehicle, an audio alarm warning (AL), operating with a given first class of risk in regard to functional safety (L1), which comprises: providing (105), stored, a plurality of acoustic-alarm audio signals (A i ), selecting (120), in said plurality of acoustic-alarm audio signals (A i ) stored, an acoustic-alarm audio signal (A i ) to be propagated in the audio alarm warning (AL) and fetching said acoustic-alarm audio signal (A i ), and carrying out audio reproduction (190) of said acoustic-alarm audio signal (A i )- The method described envisages: providing (105), stored, operating with a second class of risk in regard to functional safety (L2), lower than said first class of risk (L1), a plurality of combined audio signals (M i ) comprising said acoustic-alarm audio signals (A i ) associated to respective identification signals (C i ) that represent respective identifier codes (c i ), selecting (120), in said plurality of combined audio signals (M 1 , ..., M n ) a combined audio signal (M i ) that corresponds to the acoustic-alarm audio signal (A i ) to be propagated in the audio alarm warning (AL), and fetching said combined audio signal (M k ) from the plurality of combined audio signals (M i ), extracting (130), from said combined audio signal (M k ) fetched, said identification signal (C i ), and extracting (130), from said identification signal (C i ), said identifier code (c i ), verifying (150), operating according to said first class of risk (L1), the correspondence between said identifier code (c k ) of the combined audio signal (M k ) fetched and the identifier code (c i ) of the acoustic-alarm audio signal (A i ) to be propagated in the audio alarm warning (AL).
