[0005] Interface system for a bicycle
[0006] State of the art
[0007] The present invention relates to an interface system for a bicycle, a bicycle, and a method for operating such an interface system. Bicycle interface systems comprising one or more user interfaces are known. The user interfaces can be arranged on the bicycle at various locations. Typically, each user interface has predetermined functions and properties. These are usually assigned before the bicycle is put into operation, often manually or during the manufacturing of the user interface.
[0008] Disclosure of the invention
[0009] In contrast, the interface system according to the invention with the features of claim 1 is characterized by the fact that, with a simple and cost-effective design of the interface system, particularly flexible and simple individual configuration of user interfaces is possible. This is achieved according to the invention by an interface system for a bicycle, comprising at least one first user interface and a control unit. The first user interface is designed for attachment to the bicycle. The first user interface and the control unit are each configured to communicate with each other via a wireless connection. The control unit is configured to determine a relative arrangement of the first user interface and the control unit to each other based on the wireless connection.Furthermore, the control unit is configured to assign a predetermined configuration to the first user interface based on the relative arrangement thus determined. R.414083.
[0010] - 2 -
[0011] In particular, a user interface is defined as a device of the interface system designed for interaction with a user of the bicycle. For example, the user interface may include an electronic device configured to process electronic data.
[0012] Preferably, the user interface and the control unit can exchange information, especially data, with each other via the wireless connection.
[0013] Preferably, the control unit can analyze current properties of the wireless connection in order to determine the relative arrangement of the first user interface and the control unit based on this.
[0014] A predetermined user interface configuration is understood to be, in particular, a predetermined property and / or function to be assigned to the user interface, which can preferably be provided purely through measures for electronic data processing.
[0015] In other words, an interface system is provided which includes at least a user interface and a control unit that can communicate with each other wirelessly, and in particular, can be connected to each other wirelessly. The user interface, and preferably also the control unit, can be mounted on the bicycle. Preferably, the user interface and control unit can be mounted on the bicycle in a fixed position relative to each other, or alternatively, movable relative to each other, preferably based on the mobility of bicycle components, such as a handlebar that is rotatably mounted relative to a bicycle frame.Based on the wireless connection between the user interface and the control unit, the control unit can determine the current relative arrangement, in particular the relative position and / or orientation, of the two devices to each other. R.414083.
[0016] - 3 -
[0017] The interface system offers the advantage that, with a simple and cost-effective design using few components, and especially based on the inherent properties of the assembled components of the interface system, the relative arrangement of the user interface and the control unit can be determined, and based on this, a specific configuration can be automatically assigned to the user interface. For example, this eliminates the need to manually assign the configuration to the user interface during assembly of the interface system or during initial commissioning. Instead, the configuration assignment can be determined automatically by the control unit and the relative arrangements determined based on the wireless connection.
[0018] Preferably, the assignment of the predetermined configuration can be achieved by selecting exactly one predetermined configuration from several, for example, stored configurations and assigning it to the user interface. Advantageously, exactly one predetermined configuration can be stored in a table for each specific relative arrangement.

Thus, in a system with multiple user interfaces, each user interface can be assigned an individual, predetermined configuration in a particularly simple and efficient manner. This allows an interface system with various flexible configurations to be provided automatically and in a particularly simple way.
[0022] It is particularly advantageous for both user interfaces to be identical in design. Specifically, the two user interfaces can be structurally identical. This allows for a particularly simple and cost-effective design of the interface system. For example, regardless of its later function, each user interface can be attached to a designated mounting location on the bicycle, with the configuration being automatically assigned only after installation. This makes the assembly and provision of the bicycle particularly simple and time-efficient.
[0023] Preferably, the control unit and at least the first user interface, and preferably also the second user interface, are configured to initially establish the wireless connection via a coupling process. Preferably, the control unit is configured to determine the relative arrangement of the first user interface and the control unit, and preferably the second user interface and the control unit, to each other during or based on the coupling process of the wireless connection. That is, during the initial commissioning of the interface system, the wireless connection between the user interface and the control unit is established via the coupling process. Preferably, data such as individual identifiers of the user interface and the control unit can be exchanged during this process.This allows, for example, a particularly simple and time-efficient connection to be established when the interface system is recommissioned after the initial coupling process.

[0027] Preferably, the predetermined operating function includes an information output, in particular by means of an output element. Preferably, the output element can be an integral part of the user interface. In other words, the user interface can be configured to output this information to the user.

Alternatively or additionally, the control unit is configured to determine the relative orientation of the first user interface and the control unit based on the wireless connection. This allows for a particularly simple and cost-effective determination of the relative arrangement. Furthermore, based on the distance and / or relative orientation of the user interface and the control unit, a mounting location for the user interface can be determined particularly easily, precisely, and efficiently. This allows for a particularly simple and reliable assignment of a desired configuration to the user interface.

A third user interface 7 is also located on the handlebar 101, on the right side with respect to the direction of travel A.
[0056] Furthermore, the interface system 10 comprises several control units 3. Each control unit 3 is integrated into one of the user interfaces 1, 2, 7. Alternatively, preferably, only a single control unit 3 may be provided, which may be integrated into one of the user interfaces 1, 2, 7, or alternatively, may be provided separately, for example, as part of a separate device, such as a user device.
