Systems and methods for mitigating open vehicle window throb
Method and apparatus are disclosed for determining and mitigating wind throb caused by an open vehicle window. An example vehicle includes a plurality of windows corresponding to a plurality of seats having respective occupancy sensors, a microphone, and a processor. The processor is configured to determine that a first window is open, determine, based on microphone data, that a sound pressure level is above a threshold level, and responsively open a second window selected based on occupancy data determined by the occupancy sensors.
1. A vehicle comprising:
a plurality of windows corresponding to a plurality of seats having respective occupancy sensors;
a microphone; and
a processor configured to:
determine that a first window of the plurality of windows is open;
determine, based on microphone data, that a sound pressure level is above a threshold level; and
responsively open a second window selected based on occupancy data determined by the occupancy sensors.
2. The vehicle of claim 1 , wherein the microphone is an active noise cancellation microphone positioned in a vehicle cabin.
3. The vehicle of claim 1 , wherein the processor is further configured to determine that the first window is open while the vehicle is travelling above a threshold speed.
4. The vehicle of claim 1 , wherein the processor is further configured to determine that the sound pressure level is below 50 Hz and is greater than 115 decibels.
5. The vehicle of claim 1 , wherein the processor is further configured to:
determine a first seat of the plurality of seats corresponding to the first window;
determine, based on the first seat and the occupancy data, a nearest unoccupied seat of the plurality of seats; and
responsively open the second window, wherein the second window corresponds to the nearest unoccupied seat.
6. The vehicle of claim 1 , wherein the processor is further configured to open the second window by two inches.
7. The vehicle of claim 1 , wherein the processor is further configured to:
determine a first distance that the first window is open; and
open the second window a second distance that matches the first distance.
8. The vehicle of claim 1 , wherein the sound pressure level is a first sound pressure level, and wherein the processor is further configured to:
open the second window by a first amount;
responsively determine a second sound pressure level after the second window has been opened by the first amount; and
open the second window by a second amount based on a difference between the first sound pressure level and the second sound pressure level.
9. The vehicle of claim 1 , wherein the processor is further configured to determine a vehicle speed, and open the second window by an amount corresponding to the vehicle speed.
10. The vehicle of claim 1 , wherein the processor is further configured to determine that the plurality of seats are occupied, wherein the second window is a sunroof.
11. A method comprising:
determining that a first window of a plurality of windows is open, of a vehicle having the plurality of windows, the plurality of windows corresponding to a plurality of vehicle seats having respective occupancy sensors;
determining, based on vehicle microphone data, that a sound pressure level is above a threshold; and
responsively opening a second window based on occupancy data determined by the occupancy sensors.
12. The method of claim 11 , wherein the microphone data is captured by an active noise cancellation microphone positioned in a cabin of the vehicle.
13. The method of claim 11 , further comprising determining that the first window is open while the vehicle is travelling above a threshold speed.
14. The method of claim 11 , further comprising determining that the sound pressure level is below 50 Hz and is greater than 115 decibels.
15. The method of claim 11 , further comprising:
determining a first vehicle seat of the plurality of vehicle seats, corresponding to the first window;
determining, based on the first vehicle seat of the plurality of vehicle seats, and the occupancy data, a nearest unoccupied seat of the plurality of vehicle seats; and
responsively opening the second window, wherein the second window corresponds to the nearest unoccupied seat of the plurality of vehicle seats.
16. The method of claim 11 , further comprising opening the second window by two inches.
17. The method of claim 11 , further comprising:
determining a first distance that the first window is open; and
opening the second window a second distance that matches the first distance.
18. The method of claim 11 , wherein the sound pressure level is a first sound pressure level, the method further comprising:
opening the second window by a first amount;
responsively determining a second sound pressure level after the second window has been opened by the first amount; and
opening the second window by a second amount based on a difference between the first sound pressure level and the second sound pressure level.
19. The method of claim 11 , further comprising determining a vehicle speed, and opening the second window by an amount corresponding to the vehicle speed.
20. The method of claim 11 , further comprising determining that the plurality of vehicle seats are occupied, and responsively opening a sunroof.
