This paper proposes the concept of electronic noise and vibration diagnostic system for vehicles that aims to avoid wrong or unreasonable replacement of their components in the repair process. Our concept for a vibroacoustic diagnostic system consists of a set of sensors that receive noise and vibration, judiciously arranged and connected to a DAQ (Data Acquisition System). This allows the ECU (Electronic Control Unit) to accurately determine, by three-dimensional detection, the area in which vibroacoustic anomalies are manifesting (due to current or incipient defects). The data storage memory works according to the first in - first out principle, retaining only significant information to save resources. Establishing a mathematical model is one of the focuses for this concept for predicting the failure of various components of the vehicle based on vibroacoustic and then developing an artificial intelligence program capable of identifying and classifying new behaviours are the steps which we follow in the development of this tool. Also, the benefits of early detection of a subassembly failure are found in increasing traffic safety.
