Abstract
Monitoring performance of electric vehicle components using tonal analysis is provided. A system can receive audio data from an electric vehicle captured via a sensor associated with the electric vehicle, the audio data indicative of performance of an electric component of the electric vehicle. The system can detect a change in the performance of the electric component. The change can be detected based on a comparison of the audio data with an audio signature corresponding to the electric component of the electric vehicle. The system can provide a notification indicative of the change in the performance of the electric component responsive to the detection of the change in the performance of the electric component.
Claims20
A system, comprising:
- a data processing system comprising one or more processors, coupled with memory, to:
- transmit a call for audio data responsive to a detection of a state of an electric vehicle;
- receive the audio data captured via a sensor associated with the electric vehicle, the audio data indicative of a performance of an electric component of the electric vehicle, the electric component including a mechanically rotating electric component, and comprising an indication of amplitude at each of a plurality of sample points, the sample points spaced from one another at irregular intervals;
- determine, based on a verification that the audio data meets a sparsity threshold, that the audio data is sparse audio data;
- verify the sparse audio data based on an angle domain of the mechanically rotating electric component of the electric vehicle:
- detect, based on a comparison of the sparse audio data with an audio signature corresponding to the mechanically rotating electric component of the electric vehicle, a change in the performance of the mechanically rotating electric component;
- and
- provide, responsive to the detection of the change in the performance of the electric component, a notification indicative of the change in the performance of the mechanically rotating electric component.
