Abstract
A method for monitoring functional components of a motor vehicle is provided. To this end, microphones, pulsation sensors, strain gauges and a speed sensor are positioned on or next to one of the functional components to be monitored. The electrical signals of the microphones, pulsation sensors, strain gauges, and speed sensor are measured, analyzed by means of Fourier analysis and compared with an acoustic signature.
