Abstract

In order to improve a noise emission or noise emission which is caused by a vehicle, according to the invention the instantaneous load (L) of the vehicle (F) is determined with a method for controlling and/or regulating a load (L) of a vehicle (F) by means of a pickup unit (6, 6A to 6C) with reference to at least one operating variable (B) of the vehicle (F), the operating variable (B) being controlled and/or regulated by means of a control unit or regulator unit (2) as a function of a noise level (G(G), G(F), G(U)) resulting from the instantaneous load (L) of the vehicle (F).

Claims

1. A method for at least one of controlling and regulating a load of a vehicle comprising the steps:

determining an instantaneous load of the vehicle by means of at least one operating variable of the vehicle said operating variable being determined by means of a pickup unit;

at least one of controlling and regulating the operating variable by means of one of a control unit and a regulator unit as a function of a noise level resulting from the instantaneous load and as a function of an instantaneous position of the vehicle.

2. The method as claimed in claim 1, characterized in that the operating variable (B) on which the noise level (G(F)) is based is used as the operating variable (B).

3. The method as claimed in claim 1, wherein at least one of a rotational speed, a torque, a velocity and an acceleration are used as the operating variable (B).

4. The method as claimed in claim 1, wherein the noise level is determined by reference to at least one of the instantaneous load of the vehicle and ambient noises.

5. The method as claimed in claim 1, wherein the noise level is monitored for compliance with a limiting value.

6. The method as claimed in claim 1, wherein the operating variable is at least one of controlled and regulated as a function of time.

7. An arrangement for one of controlling and regulating a load of a vehicle, said arrangement comprising:

a pickup unit for determining an instantaneous load of the vehicle by reference to at least one operating variable of the vehicle;

at least one of a control unit and a regulating unit for at least one of controlling and regulating the operating variable as a function of a noise level resulting from the instantaneous load of the vehicle wherein said pickup unit includes a noise sensing system for determining at least one of ambient noise and vehicle-related noise.

8. The arrangement as claimed in claim 7, wherein the pickup unit is provided for sensing at least one of a velocity, an acceleration, a drive rotational speed and a drive torque.

9. The arrangement as claimed in claim 7, further including at least one of a location-determining system for determining the instantaneous position of the vehicle and an information system for determining a resulting, ambient noise level.

10. The arrangement as claimed in claim 7, wherein the control unit or regulator unit has an input device for at least one of manually controlling and regulating the operating variable.

11. The arrangement as claimed in claim 7, wherein, during at least one of the control and regulation of the operating variable, the control unit or regulator unit takes into account predefined values of external systems, in particular of a traffic control system, via the pickup unit.

12. The arrangement as claimed in claim 11, wherein the predefined values of external systems relating to at least one of the control and regulation of the operating variable is approved by at least one of the driver of the vehicle and by an occupant of the vehicle by means of the control unit or regulator unit.

13. The arrangement as claimed in claim 7, further including an output unit for outputting an instantaneous position of the vehicle and the operating variable.

14. The arrangement as claimed in claim 7, wherein the interventions of the control unit or regulator unit into the vehicle system during the one of control and regulation of the operating variable and the vehicle-related operating variables are stored in the data memory for documentation.

15. The arrangement as claimed in claim 14, wherein statistics are created from data stored in a data memory.

16. The arrangement as claimed in claim 14, wherein recommendations for maintenance and repair of the vehicle are derived from a data stored in the data memory.

17. The arrangement as claimed in claim 7, wherein interventions of the control unit or regulator unit into the vehicle system during the control or regulation of the operating variable are transferred to an external system for monitoring.
