US Patent 11074655 Cost sharing based upon in-car audio

Systems and methods may transmit a plurality of locationing pulse requests from a mobile device in a vehicle to an audio system of the vehicle during a period of vehicle operation. The mobile device may be associated with a vehicle driver. The audio system may have an array of speakers disposed inside the vehicle, and the locationing pulse requests may include a request to emit a locationing pulse from the array of speakers. The systems and methods may receive the locationing pulse at a microphone of the mobile device, and generate or update a vehicle occupancy profile based upon the receiving operation. The vehicle occupancy profile may include occupancy data of one or more seats inside the vehicle. A vehicle risk profile may be determined based upon the vehicle occupancy profile, and a risk message transmitted if the vehicle risk profile satisfies a high risk condition.
