Abstract

A system and method for active noise compensation in a vehicle is provided. The system has at least one apparatus for detecting a noise, a computer unit for calculating a compensation sound, at least one apparatus for generating a compensation sound which interferes with the noise, and a device for detecting at least one driver-specific parameter. The compensation sound is calculated depending on the at least one driver-specific parameter. Also provided is a motorcycle having a system for active noise compensation.

Claims

1. An active noise compensation system for a motorcycle, comprising:

a noise-capture unit configured to capture a noise near a driver of the motorcycle;

a driver parameter input unit configured to obtain at least one driver-specific parameter;

a computer unit configured to

receive a signal corresponding to a noise captured by the noise capture unit,

receive a signal corresponding to the at least one driver-specific parameter from the driver parameter input unit, and

calculate, based on the received noise signal and at least one driver-specific parameter signal, a compensation sound counter to the noise captured by the noise-capture unit; and

a compensation sound production unit configured to generate the compensation sound calculated by the computer unit such that the compensation sound interferes with the noise near the driver of the vehicle.

2. The system as claimed in claim 1, wherein

the driver parameter input unit includes a head position detection unit configured to capture a current position of the head of the driver.

3. The system as claimed in claim 1, wherein

the driver parameter input unit is configured to at least one of capture and receive a body size of the driver.

4. The system as claimed in claim 1, wherein

the driver parameter input unit is configured to obtain a helmet type of the driver.

5. The system as claimed in claim 1, further comprising:

a vehicle parameter input unit configured to obtain at least one vehicle-specific parameter,

wherein the computer unit is further configured to

receive a signal corresponding to the at least one vehicle-specific parameter from the vehicle parameter input unit, and

the calculation of the compensation sound is further based on the received at least one vehicle-specific parameter signal.

6. The system as claimed in claim 5, wherein

the at least one vehicle-specific parameter is a position of a windshield of the motorcycle.

7. The system as claimed in claim 4, wherein

the at least one vehicle-specific parameter is a motorcycle type of the motorcycle.

8. The system as claimed in claim 5, wherein

the at least one vehicle-specific parameter is a motorcycle type of the motorcycle.

9. The system as claimed in claim 5, wherein

the at least one vehicle-specific parameter is at least one of a vehicle speed and an engine speed of the motorcycle.

10. The system as claimed in claim 6, wherein

the at least one vehicle-specific parameter is at least one of a vehicle speed and an engine speed of the motorcycle.

11. The system as claimed in claim 7, wherein

the at least one vehicle-specific parameter is at least one of a vehicle speed and an engine speed of the motorcycle.

12. The system as claimed in claim 5, wherein

the at least one vehicle-specific parameter is an inclination of the motorcycle.

13. A motorcycle, comprising:

an active noise compensation system including

a noise-capture unit configured to capture a noise near a driver of a vehicle;

a driver parameter input unit configured to obtain at least one driver-specific parameter;

a computer unit configured to

receive a signal corresponding to a noise captured by the noise capture unit,

receive a signal corresponding to the at least one driver-specific parameter from the driver parameter input unit, and

calculate, based on the received noise signal and at least one driver-specific parameter signal, a compensation sound counter to the noise captured by the noise-capture unit; and

a compensation sound production unit configured to generate the compensation sound calculated by the computer unit such that the compensation sound interferes with the noise near the driver of the vehicle.

14. A method for active noise compensation on a motorcycle, including the acts of:

capturing a noise near a driver of the motorcycle using a noise-capture unit;

obtaining at least one driver-specific parameter of the using a driver parameter input unit;

calculating using a computer unit, based on the noise captured by the noise capture unit and the at least one driver-specific parameter obtained by the driver parameter input unit, a compensation sound counter to the noise captured by the noise-capture unit; and

producing the compensation sound which interferes with the noise calculated by the computer unit such that the compensation sound interferes with the noise near the driver of the vehicle.

15. The method as claimed in claim 14, wherein

the driver parameter input unit includes a head position detection unit configured to capture a current position of the head of the driver.

16. The method as claimed in claim 14, further comprising the act of:

obtaining at least one vehicle-specific parameter using a vehicle parameter input unit,

wherein the act of calculating the compensation sound is further based on the at least one vehicle-specific parameter signal.

17. The method as claimed in claim 14, wherein

the at least one vehicle-specific parameter is a position of a windshield of the motorcycle.

18. The method as claimed in claim 14, wherein

the at least one vehicle-specific parameter is a motorcycle type of the motorcycle.

19. The method as claimed in claim 14, wherein

the at least one vehicle-specific parameter is at least one of a vehicle speed and an engine speed of the motorcycle.

20. The method as claimed in claim 14, wherein

the at least one vehicle-specific parameter is an inclination of the motorcycle.
