  • Publication number: 20190359252
    Abstract: A system and method for passively and actively monitoring and determining the location of at least one mechanical anomaly for a power steering system of a vehicle is disclosed. The system includes one or more processors and a memory coupled to the processors. The memory stores a baseline waveform and data comprising program code that, when executed by the one or more processors, causes the system to receive at least one excitation signal and at least one response signal. The power steering system creates the response signal in response to receiving the excitation signal. In response to receiving the excitation signal and the response signal, the system is caused to estimate the frequency response between the excitation signal and the response signal based on a fast Fourier transform (FFT) algorithm. The frequency response is represented by an estimated waveform.
