Abstract

A method for suppressing braking noise in a vehicle by a central server, methods for suppressing braking noise in a vehicle to be carried out in a vehicle, and an associated central server, an associated vehicle control module and an associated data storage medium are disclosed. The data processing is divided between the vehicle and the central server.

First claim

The invention claimed is:

1. A method for suppressing braking noise in a number of vehicles by a central server,
wherein the method comprises:
receiving a number of messages from the vehicles, wherein the messages contain braking state data,
generating a plurality of driving profiles based on the braking state data, each driving profile containing a number of response instructions for braking noise suppression for a respective different driving style, and
applying the number of response instructions of one of the plurality of driving profiles based on the braking state data, wherein each response instruction contains a measure for suppressing braking noise and thereby causes the vehicle to perform a modified braking operation having suppressed noise.

2. The method as claimed in claim 1 , which also comprises at least one of:
sending the response instructions to the vehicles,
sending the response instructions to a group of vehicles,
installing the response instructions in new vehicles to be produced.

3. The method as claimed in claim 1 , which also comprises at least one of:
sending the driving profiles to the vehicles,
sending the driving profiles to a group of vehicles,
installing the driving profiles in new vehicles to be produced.

4. A method for suppressing braking noise in a vehicle, wherein the method comprises:
recording a number of braking state data,
sending the braking state data to a central server in a number of messages,
generating a plurality of driving profiles based on the braking state data, each driving profile containing a number of response instructions for braking noise suppression for a respective different driving style,
receiving the number of response instructions of one of the plurality of driving profiles from the central server, wherein each response instruction includes a measure for suppressing braking noise, and
applying the response instructions in a number of braking operations of the vehicle,
wherein the central server as claimed in claim 1 is used as the central server.

5. The method as claimed in claim 1 ,
wherein the messages are received and/or transmitted via mobile radio.

6. The method as claimed in claim 1 ,
wherein the braking state data include data relating to one or more of the following states:
noise,
braking noise,
vibrations,
braking forces,
braking force distribution,
wheel rotation speeds,
pedal travel,
pedal force,
braking torque,
deceleration,
temperatures, in particular of brakes, engine and/or environment;
and/or wherein they include CAN bus data.

7. The method as claimed in claim 1 ,
wherein a respective response instruction contains a measure for suppressing braking noise as a function of a number of braking state data.

8. The method as claimed in claim 1 ,
wherein a respective response instruction contains one or more of the following actions:
braking force distribution,
braking force reduction,
braking force modulation,
brake conditioning and/or braking regeneration.

9. The method as claimed in claim 1 ,
which also comprises in the vehicle or in the central server:
identifying a robustness measure for a component by the braking state data.

10. A central server which is configured to carry out a method as claimed in claim 1 .

11. A non-volatile, non-transitory computer-readable data storage medium, containing program code which, when carried out, causes a processor to execute a method as claimed in claim 1 .

12. A method for suppressing braking noise in a vehicle, wherein the method comprises:
recording a number of braking state data,
sending the braking state data to a central server in a number of messages,
generating a plurality of driving profiles based on the braking state data, each driving profile containing a number of response instructions for braking noise suppression for a respective different driving style,
receiving the number of response instructions of one of the plurality of driving profiles from the central server, wherein each response instruction includes a measure for suppressing braking noise, and
applying the response instructions in a number of braking operations of the vehicle.

13. A vehicle control module which is configured to execute a method as claimed in claim 12 .

14. A method for suppressing braking noise in a vehicle, wherein the method comprises:
receiving a number of driving profiles from a central server or reading out a number of driving profiles from a non-volatile memory of the vehicle, each driving profile containing at least one different driving style and an associated response instruction, each of which contains a measure for suppressing a braking noise,
identifying a driving style based on driving state data,
mapping the determined driving style to a driving style of one of the driving profiles, thereby selecting this driving profile, and
applying the response instructions of the selected driving profile in a number of braking operations of the vehicle.

15. The method as claimed in claim 14 ,
wherein if the identified driving style cannot be mapped to any driving style of a driving profile, a signal is output which indicates a service interval reduction and/or a use of other components.

16. A vehicle control module which is configured to execute a method as claimed in claim 14 .
