Abstract

A method, a device, and a two-wheeler including a device of this type, in which at least one wear parameter that represents the wear of at least one wear part or a component of the two-wheeler is generated, determined, or ascertained. It may be provided that a shared wear parameter for multiple wear parts or in each case separate wear parameters for individual wear parts is/are generated, determined, or formed. Typical components on a two-wheeler, in particular on a bicycle, that may be subject to wear include the brake pads, the brake disks, a sprocket, a chainring, a chain, or a tire. In addition, brake fluid in a hydraulic brake may also be subject to wear, it being possible for the brake fluid to absorb either air, water, or dirt, thus impairing the responsiveness of the pressure transfer.

First claim

What is claimed is:

1. A method for generating a wear parameter that represents wear of at least one wear part at a two-wheeler, the method comprising the following steps:
detecting at least one weight force parameter; and
detecting at least one use parameter of the two-wheeler;
detecting at least one intensity parameter of a use of the two-wheeler; and
determining at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the at least one use parameter and the at least one intensity parameter.

2. The method as recited in claim 1 , wherein the two-wheeler is an electric bicycle.

3. The method as recited in claim 1 , wherein at least one operating parameter of the two-wheeler is detected, a parameter that represents: (i) a temporal profile of a speed and/or acceleration at which the two-wheeler travels, and/or (ii) a delivered drive torque or a generated drive power of a drive unit of the two-wheeler, and/or (iii) a pedaling torque generated by a rider of the two-wheeler, is detected as an operating parameter, the at least one intensity parameter being determined as a function of at least one average value, and/or a variance, and/or a summation, and/or a weighting of at least one of multiple operating parameters, and wherein the operating parameter and/or the intensity parameter since a predefined point in time, is detected or determined.

4. The method as recited in claim 1 , further comprising:
comparing the wear parameter to a first threshold value; and
generating a piece of wear information when the wear parameter reaches or exceeds the first threshold value.

5. The method as recited in claim 1 , wherein a parameter that represents a weight of at least the two-wheeler, and/or a weight of a rider of the two-wheeler, and/or a weight of a trailer of the two-wheeler and/or a weight force at a trailer hitch of the trailer at the two-wheeler, and/or a load on the two-wheeler, is detected as a weight parameter.

6. The method as recited in claim 1 , wherein at least one parameter that represents: kilometers traveled by the two-wheeler, and/or a use time of the two-wheeler, and/or a number of braking operations, and/or an intensity of the braking operations as a function of the brake pressure generated at the brake, is detected as the use parameter, the use parameter being detected since a predefined point in time.

7. The method as recited in claim 1 , wherein the wear parameter is determined as a function of a weighting of the at least one weight force parameter, the at least one use parameter, and the at least one intensity parameter.

8. A device, comprising:
an evaluation unit configured to generate a wear parameter that represents a wear of at least one wear part at a two-wheeler, the evaluation unit configured to
detect at least one weight force parameter;
detect at least one use parameter of the two-wheeler;
detect at least one intensity parameter of a use of the two-wheeler; and
determine at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the at least one use parameter and the at least one intensity parameter.

9. The device as recited in claim 8 , wherein the two-wheeler is an electric bicycle.

10. The device as recited in claim 8 , wherein the evaluation unit is further configured to:
compare the wear parameter to a first threshold value; and
generate a piece of wear information when the wear parameter reaches or exceeds the first threshold value.

11. The device as recited in claim 8 , wherein the evaluation unit is further configured to:
controls a component of the two-wheeler as a function of the wear parameter to reduce a further increase of the wear parameter, the evaluation unit being configured to control the component to reduce the further increase when a second threshold value is reached or exceeded.

12. The device as recited in claim 8 , wherein the evaluation unit is further configured to:
send a piece of information via a wireless link to a central database as a function of the wear parameter.

13. The device as recited in claim 12 , wherein the piece of information is an exceedance of the wear parameter of a first threshold value.

14. A two-wheeler, comprising:
a weight sensor configured to detect at least one weight force;
a vehicle dynamics sensor configured to detect a use parameter and/or operating parameter of the two-wheeler; and
an evaluation unit configured to:
detect the at least one weight force parameter using the weight sensor,
detect the use parameter of the two-wheeler,
detect at least one intensity parameter of a use of the two-wheeler, and
determine at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the use parameter and the at least one intensity parameter.

15. The two-wheeler as recited in claim 14 , wherein the two-wheeler is an electric bicycle.
