Abstract
A device outage detector, comprising: a microcontroller; a plurality of shunt resistors, each connected to at least one of a plurality of vehicle elements; a current sensor configured to measure a plurality of instantaneous currents passing through the plurality of shunt resistors, respectively; and a voltage sensor configured to measure a plurality of instantaneous voltages across the plurality of shunt resistors, respectively, wherein the microcontroller is configured to issue a warning for a given shunt resistor if its corresponding instantaneous current is below the first threshold value and its instantaneous voltage is zero, or if its corresponding instantaneous current is above a second threshold value.
