DETAILED DESCRIPTION

[0032] FIG. 1 schematically shows a functional diagram of an example of an electric bicycle 2 according to the invention, which comprises an operating device 1 according to the invention, which is also shown as an example. The operating device 1 may be a human-machine interface HMI, also known to those skilled in the art as a “human-machine interface”. The electric bicycle 2 may be a pedelec. The operating device 1 comprises a control/regulation device 3. Furthermore, the operating device 1 comprises a light unit 4. The light unit 4 comprises at least two electric light elements 5 for emitting light L. Each of the light elements 5 may comprise one or more LEDs. The lighting elements 5 are electrically connected to the control/regulation device 3 in such a way that each lighting element 5 can be activated separately by means of the control/regulation device 3 for emitting the light L. The lighting elements 5 can therefore be individually controlled by means of the control/regulation device 3. A light code 6 with active as well as—alternatively or additionally—inactive light elements 5 of the light unit 4 can be generated by means of the control/regulation device 3. The light code 6 is animated, for example, i.e. the light code 6 can be formed by light elements 5 changing in time between their active and inactive state, whereby the change can encode information. By means of the illuminated code 6, at least one momentary state of the electric bicycle 2 can be visualized for its rider. The rider can read the illuminated code 6.

[0033] In FIG. 2, the electric bicycle 2 with the operating device 1 of FIG. 1 is shown in a partial perspective view. It can be seen that the light unit 4 is strip-shaped and comprises several light elements 5 arranged next to each other in a row 7.

[0034] FIG. 1 shows that the control/regulation device 3 is connected to a bus system 8 of the electric bicycle 2. The bus system 8 of the electric bicycle 2 can be a field bus 9 of the electric bicycle 2. In this case, the control/regulation device 3 is connected to the bus system 8 in such a way that the control/regulation device 3 can communicate in a data-transmitting manner via the bus system 8 with further components K of the electric bicycle 1 connected to the bus system 8. In this context, a first momentary state corresponds to a momentary operating state of at least one of the components K of the electric bicycle 2 connected to the bus system 8. Such a component K can be an electrical storage device B of the electric bicycle 2, in which case the first momentary state can be a charging process of the electrical storage device B.

[0035] According to FIG. 1, the operating device 1 comprises, for example, a data transmission device 10 for wireless communication with an electronic device D. The electronic device D may be carried by the rider of the electric bicycle 2. The electronic device D may be a smartphone or a smartwatch. The data transmission device 10 is electrically connected to the control/regulation device 3, so that the control/regulation device 3 can communicate wirelessly with the electronic device D in a data-transmitting manner by means of the data transmission device 10. In this case, a second instantaneous state, which can be visualized by means of the light code 6, corresponds to an instantaneous operating state of the electronic device D. For example, recourse can be made to sensor technology installed in the electronic device D, the sensor data of which can indirectly describe the second instantaneous state of the electric bicycle 2. For example, the device may comprise a GPS sensor by means of which position data can be determined that at least indirectly also reflect the position of the electric bicycle 2. Consequently, the second instantaneous state of the electric bicycle 2 may be determined by the position of the electric bicycle 2 on a virtual map or, for example, by an instantaneous distance of the electric bicycle 2 to a predetermined destination with a known position. The data transmission device 1 is configured to support “Bluetooth-Low-Energy” as a communication standard for data-transmitting communication with the electronic device D.

[0036] It can also be seen from FIG. 1 that the control/regulation device 1 comprises an inertial measurement device 11. The inertial measurement device 11 may comprise a gyro sensor. The inertial measurement device 11 may comprise at least one acceleration sensor. The inertial measurement device 11 may comprise at least one rotation rate sensor. The inertial measurement device 11 may form or be part of an inertial navigation system. The inertial measurement device 11 is electrically connected to the control/regulation device 3 in such a way that the control/regulation device 3 can access measurement data generated by the inertial measurement device 11. In this case, a third instantaneous state, which can be visualized by means of the light code 6, is determined by the measurement data. The third instantaneous state of the electric bicycle 2 can therefore be, for example, an instantaneous acceleration or an instantaneous speed of the electric bicycle 2.

[0037] It further follows from FIG. 1 that the operating device 1 comprises an input unit 12 which can be operated by the rider of the electric bicycle 2. The input unit 12 can be manually operated by the rider of the electric bicycle 2. The input unit 12 has, for example, an electromechanical pushbutton 13. The input unit 12 is electrically connected to the control/regulation device 3. By means of the input unit 12, the rider can select which of at least two instantaneous states of the electric bicycle 2 is visualized or is to be visualized by means of the illuminated code 6.

[0038] According to FIG. 1, the operating device 1 further comprises an electronic memory 14. The electronic memory 14 may comprise a flash memory F or may be a flash memory F. The electronic memory 14 is electrically connected to the input unit 12. The electronic memory 14 is electrically connected to the control/regulation device 3, so that the control/regulation device 3 can access the electronic memory 14 by means of read or write access. For example, the control/regulation device 3 is capable of machine learning, whereby learned information can be written to the electronic memory 14 by the control/regulation device 3. Thus, the control/regulation device 3 can derive and store measures based on an evaluation of past states of the electric bicycle 2, as a result of which measures the visualization of the illuminated code 6 can be automatically adjusted. For example, by evaluating past states of the electric bicycle 2, the control/regulation device 3 can learn under which conditions the electric storage unit B of the electric bicycle empties particularly quickly and then, by automatically adapting the visualization of the illuminated code 6, signal to the rider of the electric bicycle 2 how he should behave in order to avert said conditions and thus to be able to make the best possible use of a range of the electric storage unit B. However, a variety of further examples of machine learning processes of the control/regulation device 3 are also conceivable.

[0039] FIG. 3 shows the control/regulation device 1 of the electric bicycle 2 of FIGS. 1 and 2 in a bird's-eye view image sequence. On the basis of the image sequence of FIG. 3, the visualization of the at least one state by means of the animated light code 6 of the control/regulation device 1 can be understood. The individual images of the image sequence of FIG. 3 are to be understood as snapshots of the control/regulation device 1, which follow one another in a film-like manner over time t, while the control/regulation device 1 visualizes the first state of the electric bicycle 2 by means of the animated illuminated code 6. As already mentioned above, the first momentary state may be a charging process of the electric storage device B of the electric bicycle 2. Each light element 5 of the control/regulation device 1, when active, can optionally emit light L with one of at least two colors C, C1, C2. In this case, the color C, C1, C2 of the light L emitted by the respective lighting element 5 can be selected by means of the control/regulation device 3. Also, the brightness of the light L emitted by the respective light element 5 can be adjusted by the control/regulation device 3. The selection of the color C, C1, C2 thus forms an additional coding level of the light code 6 in the form of a color coding for the time sequence of the activation or deactivation of the individual light elements 5. The operating device 1 of FIG. 3 comprises an additional lighting element 5′ set off from the lighting unit 4, which is electrically connected to the control/regulation device 3 in such a way that it can be activated separately, i.e. individually, by means of the control/regulation device 3. In this case, the additional light element 5′ is part of the illuminated code 6, i.e. the illuminated code 6 can be extended by a further coding level by means of the additional light element 5′.

[0040] In FIG. 4, the operating device 1 of the electric bicycle 2 of FIGS. 1 to 3 is shown in a top view. While the sequence of images in FIG. 3 visualizes the animated light code 6 for a charging process of the electrical storage device B of the electric bicycle 2 as the latter's first momentary state, the light code 6 in FIG. 4 signals a fully charged state of the electrical storage device B as the momentary state of the electric bicycle 2.

[0041] Referring to FIG. 2, the control/regulation device 1 comprises a housing 15. The housing 15 may comprise or be made of a plastic material. The housing 15 may partially or completely surround the other components of the operating device 1. In the example of FIG. 2, the housing 15 is at least partially received in a recess 16 of a top tube 17 of a frame 18 of the electric bicycle 2. Thereby, the housing 15 rests with a flange section 19 of the housing 15 on the top tube 17.

[0042] FIG. 1 shows that the electric bicycle 2 comprises, in addition to the operating device 1, an electric drive A which forms a component K of the electric bicycle 2. The electric drive A is drive-connected to a wheel of the electric bicycle 2. Thereby, the electric storage B of the electric bicycle 2 serves to supply the electric drive A with electric power. The control unit 1 is electrically connected to the drive A and alternatively or additionally to the electrical storage unit B—in the example of FIG. 1 both to the electrical drive A and to the electrical storage unit B.

[0043] The electrical storage unit B is connected to the electrical drive A and to the electrical storage unit B. For example, the electric drive A or the electric memory B of the electric bicycle 2 is connected to the control unit 1 by means of the bus system 8 of the electric bicycle 2. In this case, a momentary state of the electric bicycle 2, which can be visualized by means of the light code 6 for a rider of the electric bicycle 2, corresponds to a momentary operating state of the electric drive A or of the electric storage device B. For example, the electric bicycle 2 comprises a handlebar having a vibration device V. The vibration device V may form a component K of the electric bicycle 2. By means of the vibration device V, a haptic vibration signal can be supplied to the rider of the electric bicycle 2. The vibration device V is connected in a data-transmitting manner to the control/regulation device 3. The vibration device V can be connected to the control/regulation device 3 in a data-transmitting manner by means of the bus system 8. In this case, the vibration device V is connected to the control/regulation device 3 in such a way that the rider can be supplied with information—for example about at least one state of the electric bicycle 2—by means of the vibration signal in addition to the illuminated code 6.
