The remote power supply systems may power auxiliary devices separate from the vehicle. Exemplary remote power supply systems may include one or more exportable power outlet boxes that include electrical power outlets for connecting the auxiliary devices. The electrical power outlets may be powered by a generator system of the vehicle. A control module associated with the remote power supply system may command one or more vehicle-specific actions designed to reduce the realized sound level at one or more nearby areas of interest when operating the vehicle in a power generation mode. ## Claims ### Claim 1 A motor vehicle, comprising: a power outlet box including an electrical power outlet; a generator system configured to power the electrical power outlet during a power generation mode of the motor vehicle; and a control module programmed to command a vehicle-specific action for reducing an amount of noise pollution realized at an area of interest near the motor vehicle during the power generation mode, the vehicle-specific action including autonomously reorienting the motor vehicle to a position that is altered relative to the area of interest, the control module programmed to command the vehicle-specific action by at least one of directly commanding the motor vehicle to perform the autonomous reorientation, or issuing an alert to a user of the motor vehicle to initiate the autonomous reorientation, wherein the area of interest comprises a specific location external to the motor vehicle at which the noise pollution originating from the motor vehicle is realized as a function of at least a distance between the motor vehicle and the area of interest and an orientation of the motor vehicle relative to the area of interest. ### Claim 2 (depends on 1) The motor vehicle as recited in claim 1, wherein the electrical power outlet is movable to a location away from the motor vehicle by unwinding a cord of the power outlet box. ### Claim 3 (depends on 1) The motor vehicle as recited in claim 1, comprising a sensor system configured to monitor an environment around the motor vehicle. ### Claim 4 (depends on 3) The motor vehicle as recited in claim 3, wherein the sensor system is configured to provide sensor data to the control module for determining when to perform the vehicle-specific action. ### Claim 5 (depends on 4) The motor vehicle as recited in claim 4, wherein the control module is further programmed to determine when the motor vehicle has entered into or is operating within a designated quiet zone based at least on the sensor data. ### Claim 6 (depends on 5) The motor vehicle as recited in claim 5, wherein the control module is further programmed to determine when the motor vehicle has entered into or is operating within the designated quiet zone based at least on noise restriction information received from a web-based server. ### Claim 7 (depends on 5) The motor vehicle as recited in claim 5, wherein the control module is further programmed to determine whether the motor vehicle is operating in the power generation mode or whether the motor vehicle has previously operated in the power generation mode at a current location when the motor vehicle is located within the designated quiet zone. ### Claim 8 (depends on 5) The motor vehicle as recited in claim 5, wherein the control module is further programmed to identify the area of interest within the designated quiet zone based at least on the sensor data. ### Claim 9 (depends on 5) The motor vehicle as recited in claim 5, wherein the control module is further programmed to analyze the sensor data in order to distinguish between a sound absorbing object and a sound reflecting object located within the environment. ### Claim 10 (depends on 1) The motor vehicle as recited in claim 1, wherein the control module is further programmed to determine a location and the orientation of the motor vehicle relative to the area of interest. ### Claim 11 (depends on 10) The motor vehicle as recited in claim 10, wherein the control module is further programmed to determine an expected sound contribution of a sound generating component of the motor vehicle relative to the area of interest. ### Claim 12 (depends on 11) The motor vehicle as recited in claim 11, wherein reorienting the motor vehicle to the position that is altered relative to the area of interest includes positioning the sound generating component to face in a direction away from the area of interest. ### Claim 13 (depends on 1) The motor vehicle as recited in claim 1, wherein reorienting the motor vehicle to the position that is altered relative to the area of interest includes moving the motor vehicle to a location that is further away from the area of interest. ### Claim 14 (depends on 1) The motor vehicle as recited in claim 1, wherein the vehicle-specific action includes modifying an operation of an engine or a traction battery pack of the motor vehicle during the power generation mode. ### Claim 15 (depends on 1) The motor vehicle as recited in claim 1, wherein the vehicle-specific action includes modifying an operation of a heating, ventilation, and air conditioning (HVAC) system of the motor vehicle during the power generation mode. ### Claim 16 (depends on 1) The motor vehicle as recited in claim 1, wherein reorienting the motor vehicle includes moving the motor vehicle to face away from the area of interest. ### Claim 17 (depends on 1) The motor vehicle as recited in claim 1, wherein reorienting the motor vehicle includes positioning the motor vehicle over a sound absorbing object as opposed to a sound reflecting object. ### Claim 18 A motor vehicle, comprising: a power outlet box including an electrical power outlet; a generator system configured to power the electrical power outlet during a power generation mode of the motor vehicle; and a control module programmed to command an autonomous reorientation of the motor vehicle relative to an area of interest in a manner that reduces an amount of noise pollution realized at the area of interest when the motor vehicle is operating in a designated quiet zone, wherein the area of interest comprises a specific location external to the motor vehicle at which the noise pollution originating from the motor vehicle is realized as a function of at least a distance between the motor vehicle and the area of interest and an orientation of the motor vehicle relative to the area of interest. ### Claim 19 A method, comprising: controlling a motor vehicle, via a control module of a remote power supply system, to generate power for powering an auxiliary device separate from the motor vehicle; and controlling the motor vehicle, via the control module, to perform a vehicle-specific action for reducing an amount of noise pollution realized at an area of interest located near the motor vehicle, the area of interest comprising a specific location external to the motor vehicle at which the noise pollution originating from the motor vehicle is realized as a function of at least a distance between the motor vehicle and the area of interest and an orientation of the motor vehicle relative to the area of interest, wherein the vehicle-specific action includes autonomously reorienting the

modifying the operation of the traction battery pack includes adjusting a rate of charging of the traction battery pack or utilizing power from the traction battery pack in place of or instead of power from an engine of the motor vehicle.
