System for acoustic diagnostics of vehicles

A system for acoustic diagnostics of a vehicle, the system comprising:

• at least one acoustic data acquisition block mounted on the vehicle, each of the at least one acoustic data acquisition block being configured to capture acoustic signals from moving components of the vehicle;
• a communication interface;
• and
• a processing unit mounted on the vehicle, the processing unit being coupled to each of the at least one acoustic data acquisition block via the communication interface, the processing unit being configured to analyze the acoustic signals to detect an abnormal condition of each of the moving components of the vehicle;
• wherein each of the at least one data acquisition block comprises:
• at least two microphones capturing sound from opposite directions and configured to capture the acoustic signals from the moving components of the vehicle;
• a memory;
• and
• a control unit configured to:
• convert the acoustic signals into digital data;
• store the digital data in the memory;
• and
• transmit the digital data to the processing unit via the communication interface;
• wherein the processing unit is configured to analyze the digital data by using an artificial intelligence (AI) model, the AI model being configured to:
• receive the digital data as input data;
• compare the digital data to a normal sound pattern of each of the moving components of the vehicle;
• and
• based on said comparison, generate a diagnostic output indicating whether at least one of the moving components of the vehicle is in the abnormal condition.
