Vehicle location assistance using audible signals
Aspects of the present disclosure relate to using audible cues to guide a passenger to a vehicle having an autonomous driving mode. For instance, one or more processors of the vehicle may receive, from a server computing device, instructions to pick up the passenger at a pickup location. The one or more processors may maneuver the vehicle towards the pickup location in the autonomous driving mode. The one or more processors may receive a signal indicating that the passenger requests assistance locating the vehicle. The one or more processors may use the signal to generate the audible cues. The audible cues may be played by the one or more processors through a speaker of the vehicle in order to guide the passenger towards the vehicle.
1. A method of using audible cues to guide a passenger to a vehicle having an autonomous driving mode, the method comprising:
receiving, by one or more processors of the vehicle, instructions to pick up the passenger at a pickup location;
maneuvering, by the one or more processors, the vehicle towards the pickup location in the autonomous driving mode;
receiving, by the one or more processors, audio information recorded using a microphone of a client computing device associated with the passenger; and
providing, by the one or more processors, audible cues to assist the passenger in locating the vehicle based on the received audio information, wherein at least one of volume, period or tempo of the audible cues is adjusted based on whether the client computing device is moving towards the vehicle or the client computing device is moving away from the vehicle.
2. The method of claim 1 , further comprising:
receiving, by the one or more processors, information identifying a current location of the client computing device.
3. The method of claim 2 , further comprising:
determining, by the one or more processors based on the information identifying the current location of the client computing device, that the vehicle is within a predetermined distance from the client computing device, wherein the audible cues are generated when the vehicle is determined to be within the predetermined distance from the client computing device.
4. The method of claim 1 , wherein the audio information is received from the client computing device.
5. The method of claim 1 , wherein the audio information is received from a server computing device.
6. The method of claim 1 , wherein the audible cues include audible instructions to assist the passenger in locating the vehicle.
7. The method of claim 1 , further comprising:
playing, by the one or more processors, the audible cues before the vehicle stops at the pickup location.
8. The method of claim 1 , further comprising:
playing, by the one or more processors, the audible cues after the vehicle stops at the pickup location.
9. A client computing device, comprising:
a display;
a microphone; and
one or more processors coupled to the microphone and the display, the one or more processors configured to:
send a request for a vehicle to pick up a passenger at a pickup location;
receive information regarding status of the vehicle indicating that the vehicle is within a certain distance from the pickup location;
surfacing a button or option on the display which allows the passenger to initiate passenger cues; and
upon the passenger using the button or option, sending a signal to the vehicle to initiate at least one of audible cues or haptic feedback cues to assist the passenger in locating the vehicle, wherein when the audible cues are initiated, at least one of volume, period or tempo of the audible cues is adjusted based on whether the client computing device is moving towards the vehicle or the client computing device is moving away from the vehicle.
10. The client computing device of claim 9 , further comprising a speaker and a haptic feedback device, wherein the one or more processors are further configured to:
generate at least one of the audible cues via the speaker or the haptic feedback cues via the haptic feedback device.
11. The client computing device of claim 10 , wherein the one or more processors are further configured to adjust an intensity and a frequency of vibrations generated by the haptic feedback device.
12. The client computing device of claim 11 , wherein the vibrations become more intense as the client computing device moves toward the vehicle.
13. The client computing device of claim 11 , wherein the vibrations become less intense as the client computing device moves away the vehicle.
14. A vehicle having an autonomous driving mode, the vehicle comprising:
a speaker; and
one or more processors coupled to the speaker, the one or more processors being configured to:
receive instructions to pick up a passenger at a pickup location;
maneuver the vehicle towards the pickup location in the autonomous driving mode;
receive audio information recorded using a microphone of a client computing device associated with the passenger; and
provide audible cues to assist the passenger in locating the vehicle based on the received audio information, wherein at least one of volume, period or tempo of the audible cues is adjusted based on whether the client computing device is moving towards the vehicle or the client computing device is moving away from the vehicle.
15. The vehicle of claim 14 , wherein the one or more processors are further configured to receive information identifying a current location of the client computing device.
16. The vehicle of claim 15 , wherein the one or more processors are further configured to determine, based on the information identifying the current location of the client computing device, that the vehicle is within a predetermined distance from the client computing device, wherein the audible cues are generated when the vehicle is determined to be within the predetermined distance from the client computing device.
17. The vehicle of claim 14 , wherein the audio information is received from the client computing device.
18. The vehicle of claim 14 , wherein the audio information is received from a server computing device.
19. A method of using audible cues to guide a passenger to a vehicle having an autonomous driving mode, the method comprising:
receiving, by one or more processors of the vehicle, a request to pick up the passenger at a pickup location;
maneuvering, by the one or more processors, the vehicle towards the pickup location in the autonomous driving mode; and
providing, by the one or more processors, audible cues to assist the passenger in locating the vehicle, wherein at least one of volume, period or tempo of the audible cues is adjusted based on whether a client computing device associated with the passenger is moving towards the vehicle or the client computing device associated with the passenger is moving away from the vehicle.
20. A method of using audible cues to guide a passenger to a vehicle having an autonomous driving mode, the method comprising:
providing, by one or more processors of the vehicle, audible cues to assist the passenger in locating the vehicle; and
adjusting, by the one or more processors, at least one of volume, period or tempo of the audible cues based on whether a client computing device associated with the passenger is moving towards the vehicle or the client computing device associated with the passenger is moving away from the vehicle.
21. The method of claim 1 , wherein the recorded audio information is used to determine whether the passenger is moving away from the vehicle or moving towards the vehicle.
22. The vehicle of claim 14 , wherein the recorded audio information is used to determine whether the passenger is moving away from the vehicle or moving towards the vehicle.
