Description

Technical Field

[0001] The present invention relates to a method of operating a gearshift mechanism for a pedal-driven vehicle, a gearshift mechanism, and a pedal-driven vehicle provided with the gearshift mechanism.

Background Art

[0002] A pedal-driven vehicle may include an automated or partially automated gearshift mechanism. Thus, in the automatic operation of the gearshift mechanism, the shift process can be triggered according to one or more driving parameters of the pedal-driven vehicle, such as the driver pedaling frequency and / or the speed of the pedal-driven vehicle.

Further features and details of the present invention can be found in the dependent claims, specification, and drawings. It is obvious that features and details described in relation to the method according to the present invention also apply in relation to the pedal-driven vehicle according to the present invention, and / or the computer program product according to the present invention, and / or the computer-readable medium according to the present invention, and / or the data carrier signal according to the present invention, and vice versa, and as a result they are always or can be referenced to each other with respect to disclosures of individual embodiments of the invention.

[0005] The present invention described herein is used, in particular with respect to improved user comfort and / or enhanced safety of pedal-driven vehicles, to provide improved driving of a gear shift mechanism, especially an automatic or partially automated gear shift mechanism, for a pedal-driven vehicle. [Means for solving the problem]

[0006] According to a first aspect, the present invention relates to a method for operating a gear shift mechanism for a pedal-driven vehicle, The gear shift mechanism is, Control unit and At least one user interface to manually trigger the shift process, It has, This method, The steps include receiving a first shift instruction, including a source indication, particularly by a control unit, A step of receiving a second shift instruction, including a source indication, particularly by a control unit, wherein the source indication of the first shift instruction and the source indication of the second shift instruction are different. A step of adapting the operation of the gear shift mechanism in accordance with a first shift instruction and / or a second shift instruction, to include, This relates to a method for operating a gear shift mechanism in a pedal-driven vehicle.

[0007] Preferably, the method steps listed may be performed in the order shown. Additionally or alternatively, at least the individual method steps may be performed iteratively, particularly in a loop, and / or at least partially simultaneously. Additionally or alternatively, the method may be shaped as a method to be implemented on a computer.

[0008] In other words, we propose a method for operating a gear shift mechanism for a pedal-driven vehicle, particularly a bicycle or electric bicycle, preferably a pederec. The gear shift mechanism comprises at least one control unit and at least one user interface for triggering a manual shift process.

[0009] In particular, the gear shift mechanism may be an automatic or at least partially automated gear shift mechanism, preferably configured to trigger a shift process (i.e., upshift or downshift) in accordance with at least one driving parameter of a pedal-driven vehicle. The driving parameter may preferably be the speed of the pedal-driven vehicle and / or the pedaling frequency of the driver of the pedal-driven vehicle. In particular, despite the automatic or partially automated driving, the driver may manually trigger the shift process via at least one user interface, supplementing or substituting for the automatic or partially automated driving.

[0010] According to the present invention, a first shift instruction is received, particularly by a control unit, and the first shift instruction includes an indication of the source.

[0011] The source indication should be understood here as an indication of who or what is responsible for this shift instruction. Thus, the source indication may be specific to an automatically triggered shift process, or it may be specific to a shift process that is manually triggered, particularly by the driver of a pedal-driven vehicle.

[0012] For example, if a pedal-driven vehicle exceeds a certain speed, an automated gear shift mechanism may generate a shift instruction to a higher gear and transmit it to the control unit. Alternatively, the shift instruction may be generated or provided directly within the control unit. In this case, the shift instruction would include a source indicator specific to an automatically triggered shift process. In contrast, if a user operates a user interface to manually trigger a gear change, a corresponding shift instruction is also generated and transmitted to the control unit, but this shift instruction also includes a source indicator specific to a manually triggered shift process.

[0013] Furthermore, a second shift instruction is received, particularly by a control unit, and this second shift instruction also includes a source indicator. In this invention, the source indicators for the first shift instruction and the second shift instruction are different. In other words, of these shift instructions, the source indicator for one shift instruction is specific to an automatically triggered shift process, while the source indicator for the other shift instruction is specific to a manually triggered shift process.

[0014] The present invention provides a step of adapting the operation of a gear shift mechanism in accordance with a first and / or second shift instruction. This adaptation may preferably include rejecting and / or prioritizing and / or fulfilling at least one shift instruction.

[0015] Within the scope of the present invention, it has been found that shift instructions from different sources can often lead to conflicts or undesirable operating behavior of the gear shift mechanism. For example, an automatically triggered shift process and a manually triggered shift process may be added together, thus leading to an unintended and excessively strong change in the gear ratio. Alternatively, a manually triggered shift process and an automatically triggered shift process may be out of sync, resulting in unfavorable, and in some cases unnecessary or unwanted, gear changes. The proposed method makes it possible to adapt the operation of the gear shift mechanism as needed when the shift instructions originate from different sources.

[0016] In particular, the first shift instruction and the second shift instruction may be received sequentially, and / or no other shift instruction may be received between the first and second shift instructions. In particular, the first shift instruction may be received sequentially before the second shift instruction. In other words, the method described may be limited to two shift instructions received directly sequentially.

[0017] Preferably, the method may further include a step of performing at least one shift instruction, in particular a first, second, or third shift instruction. For the performance of one shift instruction, a further component of the gear shift mechanism, such as a derailleur or similar, can be driven and controlled, in particular by a control unit, to perform a gear change corresponding to that shift instruction. Additionally or alternatively, the performance of a shift instruction may include placing the shift instruction on a waiting list, or, if the waiting list is empty, performing it directly.

[0018] Additionally or alternatively, the second shift instruction may be received within a predetermined time interval after the first shift instruction has been received. In other words, each method step may be executed only when the shift instruction has been received, in particular, by the control unit, within a predetermined time interval. This resolves only conflicts between shift instructions generated or received in quick succession, and ensures that time-separated shift instructions are executed in their correct order.

[0019] With respect to the present invention, preferably, the first shift instruction includes a target gear position indicator, and the second shift instruction includes a target gear position indicator, and the step of adapting the operation of the gear shift mechanism is: When the target gear position indication of the second shift instruction matches the target gear position indication of the first shift instruction, the second shift instruction is rejected, and optionally, The first step is to carry out the shift instruction, It may be made to include this.

[0020] The target gear indication should be understood here as an indication of the gear that should be engaged when the shift instruction is performed. The target gear indication can preferably be indicated by a specific gear, particularly a numerical indication. Alternatively, the target gear indication may be indicated by an actual gear indication, i.e., an indication of the gear currently engaged, and a shift direction indication, i.e., an indication of whether to upshift or downshift.

[0021] By including a target gear position indication in the shift instruction, shift instructions targeting the same target state of the gear shift mechanism can be identified. In this case, it is sufficient for one of these shift instructions to be performed, and the others may be rejected. Accordingly, it is guaranteed that only one shift instruction will be performed and that no shifts beyond the target gear position indication will occur.

[0022] Regarding the present invention, advantageously, the step of adapting the operation of the gearshift mechanism is when a second shift instruction is received within a predefined time interval after receiving the first shift instruction, particularly when the origin indication of the second shift instruction is specific to a shift process that is automatically triggered, the step of rejecting the second shift instruction, and optionally, the step of performing the first shift instruction, and may be included.

[0023] In other words, when the second shift instruction is received within a predefined time interval after receiving the first shift instruction, the second shift instruction may be ignored. This time interval can be, for example, from 0.1 second to 1 second, particularly from 0.1 second to 0.5 second.

[0024] Such a method is particularly advantageous when the origin indication of the first shift instruction is specific to a manually triggered shift process, the origin indication of the second shift instruction is specific to an automatically triggered shift process, and / or the first and second shift instructions target different shift directions, that is, for example, when the first shift instruction is an upshift and the second shift instruction is a downshift. Thereby, the driver's intention is prioritized, and an intuitive and comfortable driving behavior of the gearshift mechanism can be realized for the driver.

[0025] Within the scope of the present invention, further, grasping the execution status of the first shift instruction, the execution status being specific to whether the first shift instruction has been executed, and the step of adapting the operation of the gearshift mechanism is when the execution status is negative, particularly by the control unit, the step of rejecting the first shift instruction, and optionally, the step of performing the second shift instruction, and can be included.

[0026] In other words, if the first shift instruction has not yet been performed, the first shift instruction is replaced with the second shift instruction. This technique has been found to be particularly advantageous when the source indication of the second shift instruction is specific to a manually triggered shift process, and / or when the first and second shift instructions target different shift directions.

[0027] In particular, the step of rejecting the first shift instruction may be performed only when the source indication of the second shift instruction is specific to a manually triggered shift process. This allows the driver's intention to take precedence.

[0028] Delayed processing of shift instructions and a correspondingly negative performance status can occur, for example, when the shift process is synchronized with the dead center of the driver torque and / or when multiple short, consecutive shift processes are being processed.

[0029] The performance status should be understood here as an indication of whether the corresponding shift instruction has already been performed. Within the scope of the present invention, a positive performance status should be specific to the fact that performance has already been carried out, and a negative performance status should be specific to the fact that performance has not yet been carried out. For performance or a positive performance status, it may be sufficient here that the shift process corresponding to this shift instruction has been introduced, that is, for example, that the transducer that moves the chain has been driven or moved, particularly by the control unit. The actual completion of the shift process may have a time lag with the introduction of the shift process.

[0030] Additionally or alternatively, the step of determining the performance status of the first shift instruction, where the performance status is specific to whether the first shift instruction has already been performed, and adapting the operation of the gear shift mechanism, A third shift instruction, formed inversely to the first shift instruction, is provided by the control unit, in particular, when the performance status is positive and / or the source indication of the second shift instruction is specific to a manually triggered shift process, and optionally, A step of rejecting a second shift instruction and / or a step of performing a third shift instruction, It may be made to include this.

[0031] In other words, preferably, especially when the first shift instruction has already been performed, a third shift instruction, which is formed inversely to the first shift instruction, may be provided without a second shift instruction. This means that when the third shift instruction is performed, the first shift instruction is reversed, or canceled. This is found to be particularly intuitive for the driver. In this case, the driver will certainly have to manually trigger the shift process again in some cases, but will not have to face an uncontrolled shift process or a series of frequent short gear changes.

[0032] Preferably, in relation to the present invention, the step of adapting the operation of the gear shift mechanism is: The step of blocking the reception of another shift instruction for a predetermined period of time after receiving a second shift instruction, particularly by the control unit, It may be made to include this.

[0033] This can enable controlled processing of shift commands.

[0034] In particular with respect to the present invention, the step of adapting the operation of the gear shift mechanism is, A step of blocking the reception or generation of another shift instruction containing a source indication specific to an automatically triggered shift process for a predetermined time interval after receiving a shift instruction containing a source indication specific to an automatically triggered shift process, It may be made to include this.

[0035] In other words, after receiving a shift instruction that includes a source indicator specific to a manually triggered shift process, the system blocks the reception or generation of any other shift instructions that include a source indicator specific to an automatically triggered shift process for a predetermined period of time. The automated operation of the gear shift mechanism is thus suspended. This ensures that the automated operation of the gear shift mechanism does not interfere with the driver's manual shift instructions.

[0036] With respect to the present invention, the step of determining at least one driving parameter, or the rate of change of at least one driving parameter over time, particularly by a sensing unit, and adapting the operation of the gear shift mechanism is further, Steps include receiving a shift instruction that includes a source indicator specific to an automatically triggered shift process, and then blocking the reception or generation of another shift instruction that includes a source indicator specific to an automatically triggered shift process until the rate of change over time of at least one driving parameter reaches or falls below a predetermined limit value, It may be made to include this.

[0037] In other words, after receiving a shift instruction that includes a source indicator, which is specific to a manually triggered shift process, the system blocks the reception or generation of any other shift instructions that include a source indicator, which is specific to an automatically triggered shift process. The automated operation of the gear shift mechanism is thus suspended. This blocking is maintained until the rate of change over time of at least one driving parameter, particularly the numerical value of the rate of change over time, reaches or falls below a predetermined limit.

[0038] This may achieve the advantage that the automatic operation of the gear shift mechanism is suspended during dynamic driving situations in which the driver performs a manual shifting process, and is only reactivated once a steady or semi-steady driving state is achieved again. The rate of change over time should be understood here as the change in the relevant driving parameter per unit time.

[0039] Driving parameters may include, in particular, the speed and / or driver pedaling frequency of a pedal-driven vehicle, especially the driver pedaling frequency in the crank mechanism of a pedal-driven vehicle, and / or driver torque, especially the driver torque input via the crank mechanism of a pedal-driven vehicle, or driver power, especially the driver power input via the crank mechanism of a pedal-driven vehicle.

[0040] According to a second aspect, the present invention relates to a gear shift mechanism for a pedal-driven vehicle, At least one control unit, At least one user interface to manually trigger the shift process, The present invention relates to a gear shift mechanism for a pedal-driven vehicle, comprising the following: Preferably, the gear shift mechanism is configured to be driven by the method according to the present invention, in particular by the method according to the first aspect of the present invention. With respect to the gear shift mechanism, the same advantages described with respect to the method according to the present invention arise.

[0041] In particular, the gear shift mechanism may be configured to provide a variable gear ratio, especially within the powertrain of a pedal-driven vehicle. The gear ratio may be specific in particular to the number of rotations of the drive wheels of a pedal-driven vehicle per revolution of the crank mechanism of the pedal-driven vehicle. A high gear ratio or high gear position characterizes, in this respect, a relatively high number of rotations of the drive wheels per revolution of the crank mechanism. A low gear ratio or low gear position, conversely, characterizes a relatively low number of rotations of the drive wheels per revolution of the crank mechanism. In particular, via the crank mechanism, the driver of a pedal-driven vehicle can input driver torque or driver power to propel the vehicle, especially via the pedals of the crank mechanism.

[0042] The gear shift mechanism can be configured here as a chain-driven shift mechanism or a hub-integrated shift mechanism. Additionally or alternatively, the gear shift mechanism may be configured as an automatic or at least partially automated gear shift mechanism. Particularly preferably, the gear shift mechanism can be configured to automate the shift process to initiate or execute it based on one or more driving parameters, particularly in accordance with the driver pedaling frequency and / or the speed of a pedal-driven vehicle. The gear shift mechanism may preferably include at least one user interface, particularly a shift lever, through which the driver can manually trigger the shift process. In particular, a user interface for upshifting and a user interface for downshifting may be provided.

[0043] At least one user interface of the gear shift mechanism may preferably be an electromechanical user interface, that is, an interface that converts mechanical operations, particularly mechanical operations by the driver of a pedal-driven vehicle, into electrical signals. For example, the user interface may be a shift lever that operates a switch during operation.

[0044] Preferably, the gear shift mechanism may include at least one gripping unit. The at least one gripping unit may, in particular, have at least one sensor or at least one sensor element for sensing the driving parameters of a pedal-driven vehicle. The rate of change of the driving parameters over time can be determined, in particular, by differentiating the sensor signal obtained with respect to the driving parameters, especially a time-discrete sensor signal, with respect to time.

[0045] In particular, at least one grasping unit may have at least one speed sensor for determining the speed of a pedal-driven vehicle. The at least one speed sensor may be configured to measure the speed of the pedal-driven vehicle, for example, via the rotational speed of the wheels of the pedal-driven vehicle and the outer circumference of these wheels.

[0046] Additionally or alternatively, at least one grasping unit may have a rotational speed sensor for determining the driver's pedaling frequency, particularly in the crank mechanism of a pedal-driven vehicle.

[0047] Preferably, at least one gripping unit may further include a torque sensor for determining driver torque, particularly in the crank mechanism of a pedal-driven vehicle. Driver power can preferably be determined as the product of driver torque and driver pedaling frequency.

The pedal-driven vehicle is preferably configured to be driven by a method according to the present invention, particularly by a method according to a first aspect of the present invention. Preferably, the pedal-driven vehicle can be configured as a bicycle, preferably an electric bicycle or a pederec. With respect to the pedal-driven vehicle, the same advantages described with respect to the method and / or gear shift mechanism according to the present invention arise. The pedal-driven vehicle may preferably comprise two wheels, particularly one front wheel and one rear wheel.

[0049] A pedal-driven vehicle may preferably include at least one drive unit that provides driving torque to propel the pedal-driven vehicle. The at least one drive unit may preferably be formed as an electric motor and / or be positioned in the pedal-driven vehicle in a mid-ship motor configuration.

[0050] Within the scope of the present invention, at least one gear shift mechanism and / or a control unit and / or a gripping unit and / or at least one drive unit may have means for data processing. The means for data processing may have at least one processor and / or working memory and / or a non-volatile data storage device.

[0051] At least one control unit may be communicated and / or signaled to the user interface and / or gripping unit and / or drive unit of the gear shift mechanism, at least temporarily. In this way, data and / or open-loop or closed-loop control signals may be exchanged between the units.

[0052] At least one control unit and at least one grasping unit may be formed as a single common unit.

With respect to the computer program product according to the present invention, the same advantages as those already described with respect to the method according to the present invention and / or the gear shift mechanism and / or the pedal-driven vehicle according to the present invention arise.
