1. A computer-implemented method for detecting sensor malfunctions in an autonomous vehicle, comprising:

  • receiving, from a plurality of sensors monitoring the autonomous vehicle, sensor data including a plurality of signals from the plurality of sensors during operation of the autonomous vehicle;

    determining, by one or more processors, a first sensor of the autonomous vehicle from the plurality of sensors;

    obtaining, by one or more processors, a first set of signals associated with the first sensor from the plurality of signals;

    obtaining, by one or more processors, a second set of signals associated with a second sensor from the plurality of sensors, the second sensor disposed in a smart infrastructure component or a personal electronic device;

    based on the second set of signals, predicting, by one or more processors, a first sensor range indicative of a range of signal values associated with proper functioning of the first sensor;

    determining, by one or more processors, that the first sensor is malfunctioning when at least one signal in the first set of signals associated with the first sensors is outside the predicted first sensor range; and

    performing, by one or more processors, an action in response to determining that the first sensor is malfunctioning.
