A PART OF MARELLI
Through the use of specific electronic technologies, the sound emitted by the various mechanical moving organs of a vehicle can be used to improve the overall performances.
The development of more sophisticated control functions, based on the listening of the emitted sound and on its processing through “Signal Processing” algorithms for the purpose of extracting all the typical and distinctive information of the phenomenon to be controlled has found several applications in the automotive and industrial sector.
Magneti Marelli has developed a Smart Acoustic platform consisting of modular electronics that includes a microphone sensor with basic functions such as:
The Smart Acoustic platform is available in two versions:
The following applications have been developed so far by Magneti Marelli through the use of the acoustic platform:
The advantages derived from the use of acoustics for the aforementioned applications are tied to an overall increase in system performances as well as to optimal management of system costs based on the use of acoustic information as a “virtual sensor” that can be used by various engine control strategies.
