US 12,515,603 B1 · Detecting vehicle impacts based on interior microphones

Abstract

Techniques for detecting impacts to a vehicle body are described herein. A vehicle may receive first audio data (associated with a sound) from a microphone located inside the vehicle. Further, the vehicle may receive second audio data (associated with the sound) from a microphone that is external to the vehicle. The vehicle can compare, for example, the volumes of the first and second audio to determine a difference. The vehicle can compare the difference to a threshold to determine whether the sound corresponds to an impact to the vehicle body. For example, if the difference is below the threshold (e.g., the volume levels of the first and second audio data are similar), the vehicle can classify the sound as corresponding to an impact to the vehicle. The vehicle can control the vehicle based on the sound being classified as an impact to the vehicle body.

Dependent claims

A system comprising:

one or more processors;
and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause the system to perform operations comprising:
receiving, from a first microphone located inside a vehicle, first audio data associated with a sound;
receiving, from a second microphone located on an external surface of the vehicle, second audio data associated with the sound;
determining a volume difference between a first volume of the first audio data and a second volume of the second audio data;
determining that the volume difference is below a threshold level of difference;
determining, based at least in part on the volume difference being below the threshold level of difference, that the sound is associated with an impact between an object in an environment and the vehicle;
controlling the vehicle based at least in part on the sound being associated with the impact.

6 more elements

One or more non-transitory computer-readable media storing instructions executable by one or more processors, wherein the instructions, when executed, cause a system to perform operations comprising:

receiving, from a first microphone located inside a vehicle, first audio data;
receiving, from a second microphone, second audio data;
determining an attribute associated with the first audio data and the second audio data;
and
determining, based at least in part on the attribute, that sound associated with the first audio data and the second audio data is associated with an impact between an object in an environment and the vehicle.
