Abstract
An audio notification system for an autonomous vehicle (AV) determines that the AV is within range of a user and emits a sound though a speaker of the AV to notify that the user that the vehicle has arrived. The audio notification system may include a sensor for sensing that the user has accessed the AV, and turns off the sound in response to the user accessing the AV. The audio notification may be generated according to one or more audio options, e.g., volume, pitch, or audio pattern.
