Ambient situation awareness system and method for vehicles
DCFirst Claim
Patent Images
1. A vehicle situation awareness device for a vehicle comprising:
- a notification device in the vehicle configured to emit an audio signal;
an internal microphone configured to measure an internal acoustic signal in the vehicle;
an ambient microphone configured to measure an ambient acoustic signal external to the vehicle; and
a processor configured to;
determine an internal sound pressure level (SPL) in the vehicle based on the internal acoustic signal,identify at least one sonic signature from the ambient acoustic signal, andwhen the at least one sonic signature is identified, determine whether to send an emit signal to the notification device to emit the audio signal based on the internal SPL.

Abstract
Methods and devices for situation awareness facilitation for a vehicle driver are provided. A method includes receiving a first acoustic signal from outside a vehicle that the driver is in and converting the first acoustic signal into a first acoustic electronic signal; sending the first acoustic electronic signal to a processor; matching the first acoustic electronic signal by the processor to stored reference electronic signals; and sending an acoustic message associated with a matched reference electronic signal to a speaker in the cab of the vehicle.

1. A vehicle situation awareness device for a vehicle comprising:
-
a notification device in the vehicle configured to emit an audio signal; an internal microphone configured to measure an internal acoustic signal in the vehicle; an ambient microphone configured to measure an ambient acoustic signal external to the vehicle; and a processor configured to; determine an internal sound pressure level (SPL) in the vehicle based on the internal acoustic signal, identify at least one sonic signature from the ambient acoustic signal, and when the at least one sonic signature is identified, determine whether to send an emit signal to the notification device to emit the audio signal based on the internal SPL. - View Dependent Claims (2, 3, 4, 5)

6. A vehicle situation awareness device for a vehicle comprising:
-
a notification device in the vehicle configured to emit an alert signal including an audio signal; an internal microphone configured to measure an internal acoustic signal in the vehicle; an external microphone configured to measure a vehicle equipment signal; and a processor configured to; determine an internal sound pressure level (SPL) in the vehicle based on the internal acoustic signal, identify at least one sonic signature from the vehicle equipment signal, and when the at least one sonic signature is identified, determine whether to send an emit signal to the notification device to emit the audio signal based on the internal SPL. - View Dependent Claims (7, 8, 9, 10)

11. A vehicle situation awareness device for a vehicle comprising:
-
a notification device in the vehicle configured to emit an alert signal to a first processor, the first processor used to modify an operation of the vehicle responsive to the alert signal; an internal microphone configured to measure an interior vehicle acoustic signal in the vehicle; an external microphone configured to measure an external vehicle acoustic signal; and a second processor, configured to; determine an interior sound pressure level (SPL) in the vehicle based on the interior vehicle acoustic signal; identify at least one sonic signature from at least one of the interior vehicle acoustic signal or the external vehicle acoustic signal, and when the at least one sonic signature is identified, determine whether to send an emit signal to the notification device to emit the alert signal based on the interior SPL. - View Dependent Claims (12, 13, 14)

15. A method of situation awareness facilitation for a vehicle driver of a vehicle, the method comprising:
-
receiving an internal acoustic signal from inside the vehicle and converting the internal acoustic signal to an internal acoustic electronic signal; receiving an ambient acoustic signal from outside the vehicle and converting the ambient acoustic signal into an ambient acoustic electronic signal; determining, by a processor, an internal sound pressure level (SPL) in the vehicle based on the internal acoustic electronic signal; matching, by the processor, the ambient acoustic electronic signal to one or more stored reference electronic signals; and determining whether to send an acoustic message associated with a matched reference electronic signal to a speaker in the vehicle based on the internal SPL.
