    Abstract: Methods and apparatus are provided for controlling noise in a cabin of a vehicle. In various embodiments, a method for controlling noise in a cabin of a vehicle includes measuring a first sound via a microphone in the cabin; obtaining a second sound from a loudspeaker of the cabin; estimating, via a processor, a third sound at a virtual location that is remote from both the microphone and the loudspeaker, using the first sound, the second sound, and one or more transfer functions; and applying active noise cancellation for the cabin based on the third sound at the virtual location.

    Abstract: Methods and systems are provided for dynamic sound enhancement for a mobile platform. The system comprises a memory for storing a plurality of unique sound profiles, and a processor communicatively coupled to the memory. The processor receives an identification (ID) for the mobile platform, a driving mode, and references the memory using the ID and driving mode to select a sound profile. The processor also receives sail status data and engine status data for the engine, which indicates whether the engine is in sail mode or not, and the progression of the mobile platform within sail mode. Responsive to the sail status and engine status data, and in accordance with the selected sound profile, the processor generates commands for an audio system coupled to the mobile platform.

    Abstract: A method for controlling an extended-range electric vehicle including an internal combustion engine and an electronic sound enhancement system includes selecting a preferred engine order equalization, said preferred engine order equalization achieving a desired engine sound in a passenger compartment of the vehicle responsive to an operator input to an accelerator pedal and decoupled from actual engine operation responsive to a state of charge (SOC) of a propulsion battery. Sound is generated in the passenger compartment by the electronic sound enhancement system responsive to the preferred engine order equalization.

    Abstract: An automotive vehicle includes an internal combustion engine that generates exhaust gas and an exhaust system that expels the exhaust gas from the vehicle via at least one of a first exhaust conduit and a second exhaust conduit. A disturbance sensor is installed within a cabin of the vehicle, and is configured to detect a disturbance within the cabin and to output a disturbance signal indicative of the disturbance. An exhaust valve has a plurality of positions and adjusts an amount of the exhaust gas delivered to the first and second exhaust conduits. The automotive vehicle further includes an electronic hardware controller in signal communication with the at least one disturbance sensor and the exhaust valve. The controller adjusts the position of the exhaust valve based on the disturbance signal to reduce the disturbance within the cabin.
