Abstract

An AV includes at least one memory and at least one processor coupled to the memory, configured to execute the stored instructions to perform the following: receive inputs from one or more acoustic sensors positioned at one or more locations on the AV, with the sensors capturing audio signals associated with AV operation in its surrounding environment. The AV processes these inputs to identify audio signals generated by specific components of the AV. The AV processes the inputs to isolate distinct sound patterns to determine if they are indicative of an anomaly associated with a component failure. The AV analyzes these audio signals to detect periodic sound patterns related to tire rotation, assessing the frequency and amplitude of these patterns to identify a specific tire exhibiting an anomaly. In response to detecting a tire anomaly, the AV initiates a corrective action by the AV to address the detected issue.

Dependent claims

A computing system for detecting anomalies of an autonomous vehicle (AV) while navigating a route, the system comprising:

at least one memory configured to store machine executable instructions;
and
at least one processor coupled to the at least one memory and configured to execute the machine executable instructions to:
receive a plurality of inputs from one or more acoustic sensors positioned in one or more locations of the AV, wherein the acoustic sensors are configured to capture audio signals associated with operation of the AV from an environment surrounding the AV;
process the plurality of inputs to identify one or more audio signals from the one or more acoustic sensors that are generated by at least one component of the AV;
in response to identifying the one or more audio signals, processing the one or more audio signals to isolate one or more sound patterns to identify whether the sound patterns are associated with an anomaly that represents a failure of the at least one component of the AV;
process the one or more sound patterns to identify periodic sound patterns associated with tire rotation, wherein the processing includes a determination of a frequency and an amplitude of the periodic sound patterns to detect a specific tire of the AV exhibiting the anomaly;
and
initiate a corrective action by the AV in response to detecting a tire anomaly.
