Claims15
A system comprising:
- a microphone unit coupled to a roof of an autonomous vehicle, the microphone unit comprising:
- a microphone board having a first opening;
- a first microphone positioned over the first opening and coupled to the microphone board;
- and
- an accelerometer, wherein the accelerometer measures vibrations proximate to the microphone unit and generates an electrical signal indicative of a waveform associated with the measured vibrations, and wherein the measured vibrations are caused by sounds external to the autonomous vehicle;
- and
- a processor coupled to the microphone unit.
4 more elements
A method comprising:
- receiving, at a processor, an electrical signal generated by an accelerometer, the accelerometer included in a microphone unit that is coupled to a roof of an autonomous vehicle, and the electrical signal indicative of a waveform associated with vibrations measured by the accelerometer, wherein the measured vibrations are caused by sounds external to the autonomous vehicle;
- and
- determining a cause of the vibrations based on the electrical signal.
A non-transitory computer-readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions, the functions comprising:
- receiving, at a processor, an electrical signal generated by an accelerometer, the accelerometer included in a microphone unit that is coupled to a roof of an autonomous vehicle, and the electrical signal indicative of a waveform associated with vibrations measured by the accelerometer, wherein the measured vibrations are caused by sounds external to the autonomous vehicle;
- and
- determining a cause of the vibrations based on the electrical signal.
