Abstract

A method for influencing sound in an aggregate in the periphery of an internal combustion engine of a vehicle, particularly in an exhaust system of the internal combustion engine, a sound-influencing signal being generated on the basis of a detected sound emission of the aggregate and being injected into the aggregate, in which additionally, the sound-influencing signal is generated as a function of a parameter that is independent of the operating point of the internal combustion engine.

Claims

1. A method for influencing sound in an aggregate in a periphery of an internal combustion engine of a vehicle, comprising:

generating a sound-influencing signal as a function of a detected sound emission of the aggregate and a parameter that is independent of an operating point of the internal combustion engine; and

injecting the sound-influencing signal into the aggregate.

2. The method according to claim 1, wherein the sound is influenced in an exhaust system of the engine.

3. The method according to claim 1, further comprising storing two control objectives for generating the sound-influencing signal, one of the control objectives or an average value of the control objectives being used for generating the sound-influencing signal as a function of the parameter.

4. The method according to claim 1, wherein the parameter describes a behavior of a driver of the vehicle.

5. The method according to claim 4, wherein the driver behavior described by the parameter is at least one of a manner of operating an accelerator of the vehicle, a gear selected specific to a vehicle speed and a selected cornering speed of the vehicle.

6. The method according to claim 1, further comprising storing the parameter specific to a driver of the vehicle, and wherein upon recognition of the driver by the vehicle, the parameter is used in generating the sound-influencing signal.

7. The method according to claim 1, wherein the parameter has information about at least one of a geographical location of the vehicle and the time, so that the sound-influencing signal is generated as a function of at least one of the geographical location of the vehicle and the time.

8. The method according to claim 1, wherein the parameter includes information about a setting of one component of the vehicle, so that the sound-influencing signal is generated as a function of the setting of the component.

9. The method according to claim 8, wherein the component is a variable convertible top of the vehicle.

10. A sound-influencing device for influencing sound in an aggregate in a periphery of an internal combustion engine of a vehicle, comprising:

means for generating a sound-influencing signal as a function of a detected sound emission of the aggregate and a parameter that is independent of an operating point of the internal combustion engine; and

means for injecting the sound-influencing signal into the aggregate.

11. A computer-readable medium containing a computer program which when executed by a processor performs the following method for influencing sound in an aggregate in a periphery of an internal combustion engine of a vehicle:

generating a sound-influencing signal as a function of a detected sound emission of the aggregate and a parameter that is independent of an operating point of the internal combustion engine; and

injecting the sound-influencing signal into the aggregate.
