    摘要: A vehicle and an associated method for augmenting audible sound generated in a passenger compartment by operation of first and second torque machines are described. The passenger compartment includes an audio speaker that is operably controlled by a controller that is also is in communication with the first and second torque machines. The controller includes an instruction set that is executable to determine first parameters associated with audible sound generated by operation of the first torque machine and determine second parameters associated with audible sound generated by operation of the second torque machine. A desired audible sound in the passenger compartment is determined. The audio speaker is controlled to generate a correction tone based upon the first parameters, the second parameters and the desired audible sound in the passenger compartment.

    摘要: Systems and method are provided for controlling a vehicle. A method of soundscape selection in a vehicle includes receiving a number of biometric parameters from sensors provided within an interior of the vehicle, and determining a state-of-mind of an occupant within the interior of the vehicle based on the biometric parameters. The method further includes selecting, with a soundscape determination module including a processor, a soundscape responsive to the state of mind of the occupant, and providing to the vehicle a set of vehicle parameters based on the selected soundscape.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A method for noise cancellation includes monitoring a system for a current operating point, monitoring the system for a predetermined disturbance, and in response to the predetermined disturbance, determining the disturbance to be in one of a transient or steady state response period. A set of data is selected corresponding to the current operating point of the system, the disturbance, and the response period from a database containing predetermined noise cancellation waveform data. A noise cancelling waveform is output to audio transducers based upon the selected set of data.
