Abstract
The present disclosure relates to enabling an autonomous vehicle operating in a self-driving mode to communicate information about what the vehicle is about to do or is currently doing. For example, one or more processors may maneuver a vehicle in an autonomous or self-driving mode. While maneuvering the vehicle in the autonomous driving mode, a time when the vehicle will begin to accelerate may be determined. A first audible signal may be played through a speaker at a time t seconds before the time when the vehicle will begin to accelerate. While maneuvering the vehicle in the autonomous driving mode, a time when the vehicle will begin to decelerate may also be determined. A second audible signal, different from the first audible signal, may be played through the speaker at the time when the vehicle begins decelerating.
