Positional audio in a vehicle-to-vehicle network
First Claim
1. A method for controlling distribution of audio data to speakers in a first vehicle participating in a vehicle-to-vehicle network in which participating vehicles generate audio data that is transmitted to other participating vehicles, comprising:
- receiving a plurality of audio data streams comprising an audio data stream received from each of a plurality of vehicle-to-vehicle network participant vehicles of the vehicle-to-vehicle network;
providing indications of the received plurality of audio data streams to a user of the first vehicle to allow selection of audio data streams received from the plurality of vehicle-to-vehicle network participant vehicles to play over a speaker system of the first vehicle;
receiving an input from the user of the first vehicle selecting one of the received plurality of audio data streams received from a second vehicle participating in the vehicle-to-vehicle network;
establishing a geographic bearing of the second vehicle relative to the first vehicle using geographic position information of the first vehicle and the second vehicle;
mapping the established geographic bearing of the second vehicle relative to the first vehicle onto specific speakers of the speaker system of the first vehicle;
selecting the specific speakers in the first vehicle to distribute the selected audio data stream received from the second vehicle in accordance with the mapped established geographic bearing; and
distributing the selected audio data stream received from the second vehicle to the selected specific speakers in the first vehicle in accordance with the established geographic bearing.

Abstract
In a vehicle-to-vehicle network, a driver may listen to audio generated by other drivers participating in the network. The usability of the audio is enhanced by determining the relative positions of the providing and the receiving vehicles and then distributing received audio to specific speakers in the audio system of the receiving vehicle to create an impression that the sound originates from a source on the line between the two vehicles. The audio distributed to different speakers in the vehicle changes as the relative positions of the two vehicles changes. Volume changes and Doppler effects can be added to the audio if the two vehicles are converging or diverging.
