Abstract
A vehicle computing system may implement techniques to emit warning sounds from a vehicle to notify other entities in an environment with the vehicle of the vehicle operation. A vehicle computing system may be configured to emit warning sounds based on a speed associated with the vehicle. The vehicle computing system may determine a planned vehicle trajectory and that a speed corresponding to the planned vehicle trajectory is associated with the warning sound emission. The vehicle computing system may determine a time that the vehicle will be at the speed and may emit the warning sound substantially at the time. In some examples, the vehicle computing system may emit a different sound prior to the time and may transition to the warning sound associated with the speed at the time. By warning other entities of the vehicle operation, the warning sound emission system may improve the safety of vehicle operation.
