Abstract
A method of processing data for a driving automation system, the method comprising steps of: obtaining sound data from a microphone of an autonomous vehicle; processing the sound data to obtain a sound characteristic; and updating a context of the autonomous vehicle based on the sound characteristic.
Claims17
A method comprising:
- by a processing circuitry of a driving automation system configured to operate an autonomous vehicle:
- obtaining, by the processing circuitry, external sound data of sounds external to the autonomous vehicle received from a microphone of the autonomous vehicle comprising an interior and an exterior, wherein the microphone is configured on the autonomous vehicle to receive sounds external to the autonomous vehicle;
- processing, by the processing circuitry, the external sound data to obtain a type of sound, wherein the processing comprises:
- updating a context of the autonomous vehicle based on the type of sound;
- in response to updating the context, generating a control signal to modify a behavior of the driving automation system, the control signal comprising instructions to cause the driving automation system to change at least one state of the autonomous vehicle, wherein the change to the at least one state of the autonomous vehicle comprises at least one of:
- a change in road position, a change in lane position, a change in speed, a change in direction, or a reduction in volume of a sound system of the autonomous vehicle;
- in response to the changed state, while operating the autonomous vehicle, performing frequency analysis on the external sound data to obtain a sound pattern;
- comparing the sound pattern with at least one sound signature stored in a memory of the driving automation system to determine the type of sound;
- and
- upon determining that the type of sound comprises a braking sound followed by a collision sound, transmitting an emergency call signal, the emergency call signal comprising a location of the autonomous vehicle.
