    SHIFT DEVICE AND CYCLE The present invention relates to a shift device for shifting a bicycle gear, such as a hub gear, of a bicycle comprising a main control unit and preferably a motor control unit. Further, the present invention relates to a bicycle with integrated drive coordination for performing a central power coordination of motor power and human power from a main control unit.
    It is known that bicycles are equipped with a gear so that the pedaling force and pedaling speed can be adapted to the speed of the bicycle and conditions such as wind and slope of the road. In the prior art, such a gear is also carried out automatically on the basis of, for instance, the speed of the bicycle by means of a facility in a gear hub, whereby gears are shifted on the basis of the rotation of a flywheel. Electric actuators have also been used for gear shifting. A drawback of such systems is that they are added to a bicycle as a separate accessory and that, for example, the user has to shift gears by means of a button module.
    It is an object of the present inventor to provide a combination of an electric auxiliary drive bicycle and a main control unit and an automatic bicycle gear that can take into account a current state of a driving motor control and/or a current state of a existing pedaling power. To this end, the present invention provides a shifting device for shifting a bicycle gear, such as a hub gear, of a bicycle comprising a main control unit and preferably a motor
    control unit, comprising: — a shift control unit for receiving shifting instructions from the main control unit or the motor control unit, comprising a processing unit and a memory, — power consumption means, such as comprising a power connector, for drawing power from a battery of the main control unit and/or a driving motor battery of the bicycle, — a shifting motor, such as an electric motor, such as a stepping motor for providing a shifting movement for driving a shifting assembly for actuating a gear actuator, — the shifting assembly for transferring the shifting movement from the shifting motor to the gear actuator, — the gear actuator for transferring the shift movement to the bicycle gear, wherein: — the shift control unit is configured as a subsystem of the bicycle by communicating with the main control unit and/or the motor control unit of the bicycle and controlling it thereby the bicycle, and - the shift control unit always shifts the bicycle gear based on shifting instructions from the main control unit and/or the motor control unit.
    It is an advantage of such a shifting device according to the present invention that it functions as a subsystem of the bicycle under control of the main control unit and/or the motor control unit by means of shifting instructions. In this way it is advantageously realized that the shifting of the gears takes place on the basis of information from the main control unit and/or the motor control unit.
    This further realizes that the shifting instructions can be composed on the basis of information available to the main control unit and/or the motor control unit. Such information concerns information relating to pedaling force or pedaling speed, speed of the vehicle which can be determined, for example, on the basis of parameters of the drive motor. It is further provided here that shortly before or during shifting the engine power or the driving force of the engine is slightly increased for a short time to relieve the bicycle acceleration during shifting. It is further provided here that switching is performed on the basis of decision rules comprising combinations of such parameters. By using a drive motor in the hub of the front wheel and a bicycle gear in the hub of the rear wheel, it is advantageously realized that forces from the motor do not load the bicycle gear, but more importantly can relieve it. The motor power in such a configuration is not applied to the gear hub, nor does it affect the measurement of the user's pedaling force or pedaling speed on the crankshaft.
    According to a further preferred embodiment, the shifting device comprises at least one sensor for determining the current acceleration of the bicycle acceleration and/or a current position of the acceleration actuator, preferably functioning together with at least one position indicator for the bicycle acceleration and/or the acceleration actuator. In this way, the shifting device during use retains knowledge of the correct position of the gear actuator and thus the bicycle gear in order to keep the bicycle gear correctly shifted and/or to switch correctly between gears.
    To this end, the switching device further preferably comprises the at least one sensor at least one hall sensor, preferably functioning in cooperation with the at least one position indicator, such as a magnetic element generating a magnetic field for actuating the at least one hall sensor. In this way a position of the bicycle gear and/or the gear actuator can be determined in an advantageous manner. Preferably, the orientation of any of the at least one position indicator relative to any of the at least one is determined such that activation of the sensor by the position indicator indicates a correct shifting of the bicycle gear. It is further provided here that any actuation of the shifting motor beyond or in addition to an actuation of the sensor by the position indicator can be used for a calibration or ongoing calibration of the shifting of the bicycle gear.
    More preferably, one of the at least one position indicator functions as a zero point indicator or exit point indicator, preferably designed as a double or deviating magnetic element. It is hereby possible to realize that in the event of a complete disconnection of a power supply to the shifting device or the main control unit of the bicycle, a recalibration can be achieved by the shift control unit actuating the shifting motor until the zero point indicator or output point indicator is present at a respective sensor. This position is then preferably stored as a starting point for a next calibration.
    Further preferred shifting device wherein the at least one sensor is arranged adjacent an edge of the bicycle gear or the gear actuator, preferably on a suitably shaped printed circuit board, and wherein the at least one position indicator is arranged in or on the bicycle gear or the gear actuator .
    A further preferred shifting device wherein the shifting assembly includes a transmission for transferring the shifting movement from the shifting motor to the gear actuator.
    A further preferred shifting device wherein the shifting motor comprises a rotation shaft with a drive means, such as a worm or threaded rod.
    Further preferred shifting device comprising a housing, preferably comprising an opening for admitting the gear actuator to the bicycle gear.
    Further preferred shifting device adapted for arrangement between the hub and the lower rear fork, preferably also adapted for arrangement within an inner contour of a chain case of the bicycle.
    A further preferred shifting device wherein the shifting control unit is adapted to transmit shifting instructions to the main control unit or the motor control unit. A further aspect of the present invention relates to a bicycle with integrated drive coordination for performing a central power coordination of engine power and human power from a main control unit, the bicycle comprising: — a frame coupled thereto with a front wheel and a rear wheel which is manpower drivable from a crankset, — a drive battery for providing energy for the engine power, — a drive motor for the providing the engine power, — a gear assembly for gear shifting of human power drive, — the master controller for providing the integrated drive coordination by performing the central power coordination of engine power and a human power, the main control unit comprising: - drive motor control means for controlling the drive motor, - drive motor monitoring means for monitoring at least one status of the drive motor, - means for composing shift instructions based on the at least one status of the drive motor, such as including a rotational speed.
    By means of such an aspect there is provided a bicycle with which, by means of a main control unit, shift instructions can be composed for a shifting device which, as a subsystem of the bicycle, shifts a bicycle gear. It is further advantageously possible hereby to realize that the motor power present or to be used and manpower power can be tuned to each other in a desirably manner, such as in relation to the speed, by means of the shifting instructions.
    According to a preferred embodiment, such a bicycle according to this aspect comprises a shifting device according to the above-described aspect.
    In a further preferred embodiment, the main control unit comprises crankshaft monitoring means for monitoring pedaling force and/or pedaling movement for providing further input for compiling the shifting instructions.
    Further preferred bicycle wherein the drive motor is a hub motor which is preferably arranged in the front wheel.
    An advantage of this is that driving forces can be supplied directly from the motor to the rim of the respective wheel. As a result, loading of, for example, a drive chain of the bicycle is avoided. In the case of arranging the hub motor and the front wheel, it is advantageously realized that gears for human power drive can be arranged separately in a rear wheel hub. This also prevents a load on the rear wheel hub of the engine. Arrangement of gears for manpower in the rear wheel hub can herein be realized in an advantageous manner in a relatively simple and reliable manner.
    Further preferred bicycle wherein the gear assembly is a hub gear assembly arranged in the hub of the rear wheel of the bicycle. Further preferred bicycle wherein the main control unit comprises a battery management system.
    Further preferred bicycle comprising shifting the gearbox assembly to a predetermined gear based on a threshold value of the charge level of the drive battery, preferably followed by a downshift of the main control unit.
    A further preferred bicycle comprising receiving means for receiving from an external computer device, such as a smartphone, instructions or decision rule parameters on the basis of which a user can set shifting moments, such as for shifting at a relatively low or relatively high speed, or shifting at a relatively low or relatively high pedaling speed or switching at a relatively low or relatively high pedaling force.

    fig. 5 is a schematic representation of a preferred embodiment regarding shift points per speed.
    fig. 6 is a perspective view of a preferred embodiment according to FIG. 1 in plan view while mounted on a bicycle.
    A first preferred embodiment (Fig. 1) according to the present invention relates to a switching device 1. It comprises a connection 4 by means of a wire to a main control unit 12, as shown for example in Figs. 3 or 4, of the bicycle. From the main control unit away from the bicycle, the shifting device is actuated one for preferably each shift of the bicycle gear. For this purpose, the shift control unit of the shifting device incorporated in the printed circuit board 9 controls the motor 2 for each shift of the bicycle gear by means of current, which is also obtained via the connection 4. The motor drives the worm 8 through which the gear wheel assembly 10 is set in motion by the shifting movement of the drive motor. This eventually drives gear actuator 11 to the next gear. The gear actuator has transfer cams 31 for transmitting the movement to the bicycle gear by means of suitable corresponding cams of the bicycle gear.
    The gear actuator 11 has a plurality of magnets 24 for actuating a respective hall sensor 21, 22 which are arranged on the printed circuit board 9. This provides the shift control unit with information regarding the position of the gear actuator. A double magnet 23 provides a zero position to the respective hall sensor. For example, if due to a power interruption the control unit is no longer aware of the position of the acceleration actuator 11, it will move the acceleration actuator until the double magnet 23 reaches the respective hall sensor for the purpose of recalibrating the shifting device so that it is known in which gear the bicycle gear is in.
    In fig. 6 shows how the shifting device 1 is arranged with respect to the hub 17, the chain guard and the rear fork.
    The switching device 11 is controlled as is preferably shown in FIG. 3 from the main control unit 12 of the bicycle. The main control unit of the bicycle 12 determines shifting moments depending on predetermined parameters. To this end, for example, the motor control unit 13 provides information relating to the power of the motor and/or the speed of the bicycle. A crank sensor provides information regarding pedaling force and/or pedaling speed. It can hereby be determined by means of predetermined determination steps at which values of the parameters should be switched.
    fig. 2 is a diagram showing shifting at predetermined speeds, such as those of FIG. 5, which are always mentioned as examples in the following description, starting in step 51. Starting from the first gear 63 according to step 52, step 53 is the shifting process. If it is determined in step 60 that the speed is higher than a predetermined speed, such as 10 km/h, the shifting to the second gear 61. If it is determined in step 57 that the speed is higher than the predetermined speed, 19 shifted to third gear 58. If in step
    54 it is determined that the speed is higher than the predetermined speed 27 is switched to the fourth gear 55. If it is determined in step 56 that the speed is lower than the predetermined speed 24 is switched to the third gear 58. If it is determined in step 59 that the speed is lower than the predetermined speed 17, it is shifted to the second gear 61. If it is determined in step 62 that the speed is lower than the predetermined speed 8 shifts to first gear 63.
    In fig. 5 shows an example of shifting speeds at certain speeds where speed is leading. The user of the bicycle can, as shown in FIG. 4 from the smartphone 9', through an application, transmit the above-mentioned adjusted parameters via a Bluetooth connection 15 to the main control unit 12 of the bicycle.
    A further preferred embodiment according to the present invention relates to an actuation unit for a gear hub, which is arranged at an actuation input of the gear hub, the actuation unit comprising a housing, an actuation motor arranged in the housing for providing driving energy to the actuators. - transmission unit, a transmission unit for transmitting an actuation movement to the actuation actuation input of the gear hub, and transmission means for transmitting the driving energy from the monitor to the transmission unit. Furthermore, the actuating unit preferably comprises a position determining means or orientation determining means for determining a position or orientation of the actuation input of the gear hub.
    In the foregoing, the present invention has been described with reference to some preferred embodiments.
    Various aspects of different embodiments are deemed to be described in conjunction with one another with all combinations considered to be within the scope of the invention upon reading by a person skilled in the art based on this document being read by a person skilled in the art.
