Electrical distribution system monitoring for electric and autonomous vehicles

A computer-implemented method, comprising:

• receiving a voltage value from an engine control unit (ECU) in a power distribution system for a vehicle;
• receiving a vehicle acceleration waveform indicative of an acceleration characteristic;
• determining that the acceleration characteristic correlates with the voltage value, comprising:
• determining a correlation coefficient value associated with the acceleration characteristic and the voltage value,
• comparing the correlation coefficient value with a threshold value for correlation, and
• determining the correlation associated with the acceleration characteristic and the voltage value when the correlation coefficient value exceeds the threshold value for correlation,
• updating, based on determining that the correlation coefficient value exceeds the threshold value, a counter associated with the ECU;
• and
• generating, based on determining that the acceleration characteristic correlates with the voltage value, a diagnostic trouble code (DTC) that indicates a fault in the power distribution system.
