[0002] Vehicles, especially single-wheeled vehicles such as motorcycles, may have a gearshift lever configured to be operated by the driver's foot to change the gear of the vehicle's transmission. Here, the gearshift lever can be deflected by the foot in a first direction (generally upward) to shift up the set gear, and / or the gearshift lever can be deflected by the foot in the opposite second direction (generally downward) to shift down the set gear.

[0003] The ability to shift gears using a vehicle's gear lever can provide varying degrees of comfort for different drivers. Furthermore, the reliability of shifting gears using the gear lever can also vary depending on the driver. Summary of the Invention

[0004] This article focuses on technical issues, aiming to achieve high comfort and high reliability in the upshifting and downshifting process using the vehicle's foot-operated gear shift lever for different drivers.

[0005] The present invention provides a device for inspecting and adapting the position of a vehicle's transmission shift lever, the shift lever being configured to be deflected by the driver's foot in a first direction or in the opposite second direction, the device being configured such that...

[0006] - Determine first sensor data regarding the length of the shift travel of the shift shaft of the transmission during at least one upshift, said at least one upshift being caused by the driver of the vehicle deflecting the shift lever in a first direction;

[0007] - Determine second sensor data regarding the length of the shift travel of the transmission shift shaft during at least one downshift, said at least one downshift being caused by the driver deflecting the shift lever in a second direction;

[0008] - Based on data from the first sensor and data from the second sensor, the position of the gear shift lever is verified; and

[0009] - Based on data from the first and second sensors, the position of the shift lever is adapted to a neutral position. This adaptation includes:

[0010] -- Move the shift lever to its neutral position in the first direction to shorten the shift travel of the transmission's shift shaft caused by the driver for upshifting and lengthen it for downshifting; or

[0011] -- Move the shift lever to the neutral position in the second direction so as to lengthen the shift travel of the transmission shift shaft caused by the driver for upshifting and shorten it for downshifting.

[0012] The present invention also provides a vehicle, the vehicle comprising:

[0013] - Transmission;

[0014] - A shift lever for a transmission, the shift lever being deflected by the driver's foot in a first direction or in the opposite second direction; and

[0015] - The device according to the invention.

[0016] The present invention also provides a method for inspecting and adapting the position of a gear shift lever of a vehicle's transmission, the gear shift lever being configured to be deflected by the driver's foot in a first direction or in the opposite second direction, the method comprising:

[0017] - Determine first sensor data regarding the length of the shift travel of the shift shaft of the transmission during at least one upshift, said at least one upshift being caused by the driver of the vehicle deflecting the shift lever in a first direction;

[0018] - Determine second sensor data regarding the length of the shift travel of the transmission shift shaft during at least one downshift, said at least one downshift being caused by the driver deflecting the shift lever in a second direction;

[0019] - Based on data from the first sensor and data from the second sensor, the position of the gear shift lever is verified; and

[0020] - Based on data from the first and second sensors, the position of the shift lever is adapted to a neutral position. This adaptation includes:

[0021] -- Move the shift lever to its neutral position in the first direction to shorten the shift travel of the transmission's shift shaft caused by the driver for upshifting and lengthen it for downshifting; or

[0022] -- Move the shift lever to the neutral position in the second direction so as to lengthen the shift travel of the transmission shift shaft caused by the driver for upshifting and shorten it for downshifting.

[0023] According to one aspect, a device for checking the position of a shift lever in a (stepped) transmission of a vehicle, particularly a motorcycle, is described. The shift lever can be configured to be operated by the driver's foot, particularly deflected in a first direction (e.g., upward) or in the opposite second direction (e.g., downward).

[0024] Additionally, the shift lever can be configured, in particular via a linkage, to transmit deflection of the shift lever in a first direction as rotation of the shift shaft of the transmission in the first direction (e.g., rotation in the counterclockwise direction), and / or to transmit deflection of the shift lever in the opposite second direction as rotation of the shift shaft of the transmission in the opposite second direction (e.g., rotation in the clockwise direction).

[0025] The position of the shift lever, especially the position of the latch, can be adjusted as needed by means of an adjusting screw and / or automatically by means of an actuator (e.g., by means of an electric motor), which the vehicle driver can actuate onto the shift lever. Here, the neutral position of the shift lever, especially the neutral position of the latch, can move in a first direction or a second direction. By moving the neutral position of the shift lever in the first direction, for example, the length of the shift travel of the transmission shift shaft caused by the driver can be shortened for upshifts and lengthened for downshifts. Correspondingly, typically, by moving the neutral position of the shift lever in the second direction, the length of the shift travel of the transmission shift shaft caused by the driver can be lengthened for upshifts and shortened for downshifts.

[0026] The device is configured to determine first sensor data regarding the length of the shift travel of the shift shaft of the transmission during at least one upshift, said at least one upshift being caused by the driver of the vehicle deflecting the shift lever in a first direction. The device can, in particular, be configured to determine the first sensor data for multiple upshifts.

[0027] Additionally, the device is configured to determine second sensor data regarding the length of the shift travel of the transmission shift shaft during at least one downshift, the at least one downshift being caused by the driver deflecting the shift lever in a second direction. The device can, in particular, be configured to determine the second sensor data for multiple downshifts.

[0028] The shift shaft may have a magnet configured to rotate together with the shift shaft about its axis of rotation. The device may be configured to determine first and second sensor data using sensors, particularly Hall effect sensors, configured to detect sensor data relating to the magnetic field induced by the magnet, particularly the field strength.

[0029] The device is also configured to examine the position of the shift lever, and in particular, the suitability of the shift lever position for the driver, based on data from a first sensor and data from a second sensor. Specifically, the device can be configured to, based on the first sensor data and data from the second sensor, determine a statistical analysis, and in particular a frequency distribution, of the length of the shift shaft travel of the transmission during multiple upshifts and downshifts. The suitability of the shift lever position, and in particular, the suitability of the shift lever position, can therefore be examined based on statistical analysis, and in particular, based on frequency distribution.

[0030] Therefore, the device enables precise verification, for a specific driver of the vehicle, of whether the position of the gear shift lever is suitable for that driver, particularly whether the position of the gear shift lever is suitable for the driver's feet and / or shoes. Thus, for a specific driver of the vehicle, the comfort and reliability of the shifting process can be improved. In particular, a specific position of the gear shift lever can be identified and, if necessary, set for the corresponding driver of the vehicle.

[0031] The device can be configured to adapt the position of the gear shift lever based on data from the first and second sensors. Specifically, it can facilitate the adaptation of the gear shift lever position when it is detected that the position of the gear shift lever is unsuitable and / or incompatible with the driver.

[0032] Additionally, the device can be configured to determine a target position of the gear shift lever (suitable for the vehicle's driver) based on data from a first sensor and data from a second sensor. The device can also be configured to cause the position of the gear shift lever to be adapted according to the determined target position.

[0033] The change of the position of the shift lever and / or the setting of the shift lever position to a target position can be prompted, for example, by: outputting a prompt to the vehicle's driver (e.g., through the vehicle's user interface); and / or registering a prompt in the vehicle's fault memory (so as to prompt, through the vehicle's maintenance services, to adapt the shift lever position); and / or manipulating the vehicle's actuator (e.g., an electric motor) configured to automatically change the position of the shift lever.

[0034] By automatically adapting the position of the gear shift lever when necessary, the comfort and reliability of the gear shifting process performed by a specific driver in the vehicle can be improved.

[0035] The device can be configured to determine, based on first sensor data, the minimum, average, and / or maximum (first) length of the shift travel during multiple upshifts. Correspondingly, the device can be configured to determine, based on second sensor data, the minimum, average, and / or maximum (second) length of the shift travel during multiple downshifts. Here, the numerical value of the corresponding shift travel length can be determined accordingly.

[0036] The minimum, average, and / or maximum first length of the shift travel (for upshifting) can then be compared with the minimum, average, and / or maximum second length of the shift travel (for downshifting) to verify the position of the shift lever, and in particular, to verify the suitability of the shift lever position for the driver. Here, a deviation exceeding a predefined deviation threshold between the first length and the corresponding second length can be a indication that the shift lever position is unsuitable for the vehicle driver. By comparing the length of the shift travel during upshifting with the length of the shift travel during downshifting, the shift lever position can be verified in a particularly precise manner.

[0037] The device can be configured to compare a minimum, average, and / or maximum first length of the shift travel with a length threshold. Here, the length threshold may depend on the minimum length of the shift travel of the transmission's shift shaft (or a corresponding minimum length) necessary for a successful shift. Correspondingly, the device can be configured to compare a minimum, average, and / or maximum second length of the shift travel with the length threshold. Thus, the position of the shift lever can be verified in a particularly precise manner based on the comparison. In particular, by comparing with the length threshold, it can be precisely identified whether the position of the shift lever allows the driver to perform reliable and / or comfortable upshifting and downshifting processes.

[0038] The device can be configured to determine a target location such that, for a plurality of future gear shifts, the frequency distribution of the shift travel length determined for the plurality of future gear shifts has a higher degree of symmetry than the frequency distribution determined based on first sensor data and second sensor data. Therefore, when the frequency distribution shows that a first length of the shift travel for an upshift is greater than a second length of the shift travel for a downshift, the neutral position of the shift lever can be moved in a first direction. Alternatively, when the frequency distribution shows that a first length of the shift travel for an upshift is less than a second length of the shift travel for a downshift, the neutral position of the shift lever can be moved in a second direction.

[0039] Therefore, the position of the shift lever can be adapted to achieve the most symmetrical frequency distribution of the shift travel lengths for upshifting and downshifting.

[0040] Alternatively or supplementarily, the device may be configured to determine a target position such that, for a plurality of future shift processes, the deviation between the average second length determined for the plurality of future shift processes and the average first length is less than the deviation between the average second length determined based on first sensor data and second sensor data and the average first length. Therefore, the increased symmetry of the frequency distribution of shift travel lengths can be achieved, for example, by the convergence of the average lengths of the shift travels for upshifting and downshifting. This can be achieved by moving the neutral position of the shift lever in a first direction or a second direction (as described above).

[0041] By making the shift travel lengths for upshifting and downshifting converge, the comfort and reliability of the shifting process can be improved in a particularly precise manner for a specific driver of the vehicle.

[0043] According to another aspect, a method for inspecting the position of a transmission shift lever in a vehicle is described. The method includes: determining first sensor data regarding the length of shift travel of the transmission shift shaft during at least one upshift, said at least one upshift being caused by the driver of the vehicle deflecting the shift lever in a first direction. The method further includes: determining second sensor data regarding the length of shift travel of the transmission shift shaft during at least one downshift, said at least one downshift being caused by the driver deflecting the shift lever in a second direction. The method further includes: inspecting the position of the shift lever based on the first sensor data and based on the second sensor data, particularly inspecting the suitability of the shift lever position for the driver.

[0047] The invention will now be described in more detail with the aid of embodiments. The accompanying drawings are as follows:

[0048] Figure 1 Showing a side view of an exemplary single-wheel rutted vehicle;

[0049] Figure 2a Showing an exemplary side view of the gear shift lever;

[0050] Figure 2b Displays the shift shaft with a shift travel sensor;

[0051] Figure 3 Display exemplary statistics on shift travel during multiple shift processes; and

[0052] Figure 4 A flowchart illustrating an exemplary method for verifying the position of a foot-operated gear shift lever is shown. Detailed Implementation

[0053] As stated at the beginning, this article aims to enable comfortable and reliable gear shifting using a foot-operated gearshift lever. In this relationship, Figure 1 An exemplary (single-track) vehicle 100 is shown, having (exactly one) front wheel 102 and (exactly one) rear wheel 102. The driver 120 of vehicle 100 sits on the long seat 108 of vehicle 100. The driver 120's feet can be placed on pedal 103, allowing the driver 120 to operate the shift lever 110 with the toes of the foot placed on pedal 103 to change the set gear of the transmission 104 of vehicle 100, specifically upshifting and downshifting.

[0054] Figure 2a Further details of the exemplary shift lever 110 are shown. The shift lever 110 includes a first lever 202 that is rotatable about a first axis of rotation 203. A foot-operated latch or pin 201 is provided at the end of the first lever 202 opposite to the first axis of rotation 203, which can be operated by the foot of the driver 120 to deflect the first lever 202 upward or downward (described by double arrows 211).

[0055] The first lever 202 acts on the shift shaft 207 of the transmission 104 via the intermediate lever 205 and the shaft 206. The intermediate lever 205 is connected to the first lever 202 at a connection point 204 between the first axis of rotation 203 and the foot control latch 201. When the first lever 202 deflects upward, this causes the shift shaft 207 to rotate in a first rotational direction, or in other words, the shifting stroke of the shift shaft in the first rotational direction. Conversely, when the first lever 202 deflects downward, this causes the shift shaft 207 to rotate in the (opposite) second rotational direction, or in other words, the shifting stroke of the shift shaft in the second rotational direction (indicated by double arrow 212). The extent of rotation of the shift shaft 207, or the length of the shifting stroke of the shift shaft, depends on the length 215 of the intermediate lever 205. Alternatively or additionally, the neutral position of the latch 201 depends on the length 215 of the intermediate lever 205.

[0056] The vehicle 100 may include a shift travel sensor 111 configured to detect sensor data regarding the length of the shift travel with respect to the shift shaft 207 during a shifting process. For this purpose, as in... Figure 2b As described, a magnet 208 (specifically fixedly connected to the shift shaft 207) can be disposed on the shift shaft 207, and the magnet moves or rotates together with the shift shaft 207. The shift travel sensor 111 may include a Hall sensor configured to detect the field strength of the magnetic field generated by the magnet 208. Based on the curve of the field strength, the shift travel 210 traversed by the shift shaft 207 can be deduced. The shift travel 210 here corresponds to a defined angular range of rotation of the shift shaft 207.

[0057] During the operation of vehicle 100, for multiple gear shifting processes, multiple values ​​of the length of the corresponding shift travel 210 can be determined. Here, the values ​​of the length of the shift travel 210 for upshifting and downshifting processes can be determined. Based on the determined length values, statistical analysis of the shift travel length can be performed, for example, as in... Figure 3 As described in [the text].

[0058] Figure 3 The frequency 301 of the shift travel length 310 detected during multiple shifting processes is displayed. Here, a positive shift travel length 310 may correspond, for example, to an upshift, while a negative shift travel length 310 may correspond to a downshift. Therefore, a statistical frequency distribution 300 of the shift travel length 310 during multiple shifting processes can be determined. Based on the frequency distribution 300 of the shift travel length 310, it can be examined whether the gear shift lever 110 of the vehicle 100 is correctly set for the driver to allow for a comfortable and / or reliable shifting process.

[0059] As by Figure 3It is evident that the frequency distribution 300 of the shift travel length 310 is asymmetrical in the described example. In particular, in the average value, the shift travel length 310 achieved during each upshift is greater than the shift travel length 310 during each downshift. Because it is typically necessary for a reliable shifting process that the shift travel length 310 (absolute value) achieved during the shifting process reaches or exceeds a defined minimum length (i.e., a length threshold), the frequency distribution 300 in the described example is asymmetrical. Figure 3 In the example, the upshifting process has relatively high reliability, while the downshifting process has relatively low reliability. Additionally, the downshifting process may have relatively low comfort because it is difficult for the driver of vehicle 100 to achieve the necessary shift travel length 310 for the downshifting process.

[0060] The analysis device 101 of the vehicle 100 can be configured to determine the shift travel length 310 achieved for the shifting process (based on sensor data from the shift travel sensor 111) and store it in the storage unit 107. Furthermore, the device 101 can be configured to, based on each shift travel length 310 for multiple shifting processes, and particularly based on the frequency distribution 300 of each shift travel length 310, examine whether there is a faulty or unfavorable position of the shift lever 110, or whether the position of the shift lever 110 should be adapted for the driver of the vehicle 100. Additionally, the device 101 can be configured to prompt a change in the position of the shift lever 110 when necessary. This can be achieved, for example, by outputting a prompt to the driver of the vehicle 100 and / or to the maintenance service of the vehicle 100.

[0061] The position of the shift lever 110, and in particular the length 215 of the intermediate lever 205, can be adapted to allow the upshift and downshift processes to be performed by the driver in a comfortable and reliable manner. For example, the position of the shift lever 110 can be changed such that a symmetrical frequency distribution 300 is generated for the shift travel length 310 used for upshift and downshift processes.

[0062] The position of the shift lever 110, particularly the neutral position, can be manually set (e.g., by adjusting a screw). Optionally, the vehicle 100 may have an actuator, particularly an electric motor (not described), configured to automatically change the position of the shift lever 110, particularly the neutral position. The position of the shift lever 110 can then be automatically adapted according to the determined shift travel length 310.

[0063] Therefore, this document describes a foot-operated shift lever 110 for a motorcycle transmission 104, which allows the rider 120 of the motorcycle 110 to sequentially shift gears 104 using their foot. For upshifting, the lever 110 can be pressed upwards by the rider's foot, and for downshifting, the lever can be pressed downwards by the rider's foot. The movement of the lever 110 is transmitted here via links 205 and 206 as rotational movement of the shift shaft 207 of the transmission 104.

[0064] The foot-operated shift lever 110 of the motorcycle 100 typically has a standard position, i.e., a standard neutral position, which is not adapted to the foot geometry or shoes of the corresponding rider 120. If the rider's foot or shoes deviate too much from the normal position associated with the standard position of the foot-operated shift lever 110, the shifting process during upshifting and downshifting can be negatively affected.

[0065] For the Shift Assist System (SASS) function, a sensor 111 can be mounted on the transmission shift shaft 207 to measure the rotational movement of the shift shaft 207 relative to the housing of the transmission 104 or the motor. The sensor 111 can be used to measure the shift travel 210, and more specifically, the shift travel length 310. If the driver 120 pulls or presses the shift lever 110, the shift shaft 207 rotates in a first rotational direction or a second rotational direction, and the sensor 111 measures the angle of rotation on the shift shaft 207 (and thus the shift travel length 310). Therefore, not only during upshifts but also during downshifts, the shift travel 210 up to the corresponding end position of the shift shaft 207 can be determined during the respective shift process. If the end positions of each shift process in one direction differ from those in the other direction, then the position of the shift lever 110 can be considered unoptimal for the driver 110. The frequency of incorrect shifts may thus increase. Correction of the position of the shift lever 110 can be achieved, for example, by adjusting a screw.

[0066] Sensor data regarding the shift travel length 310 can be stored and analyzed for multiple shift processes. Based on this information, the driver 120 of vehicle 100 can determine and / or suggest and / or, if necessary, automatically set an optimized target position for the shift lever 110.

[0067] Figure 4A flowchart of an exemplary (computer-implemented) method 400 for verifying the position of the shift lever 110 (especially a foot-operated shift lever) of the transmission 104 of a vehicle 100 (especially a motorcycle) is shown. The method 400 includes: determining 401 first sensor data regarding the length 310 of the shift travel 210 of the shift shaft 207 of the transmission 104 during at least one upshift, said at least one upshift being caused by the driver of the vehicle 100 deflecting (e.g., by upward deflection) the shift lever 110 in a first direction. In particular, the first sensor data can be determined for multiple upshifts, each performed by the driver by deflecting the shift lever 110 in a first direction. Thus, the first sensor data can be determined, showing a statistical distribution of the length 310 of the shift travel 210 of the shift shaft 207 during each upshift performed by the driver of the vehicle 100.

[0068] Additionally, method 400 includes: determining 402 second sensor data regarding the length 310 of the shift travel 210 of the shift shaft 207 of the transmission 104 during at least one downshift, said at least one downshift being caused by the driver deflecting the shift lever 110 in a second direction (opposite to the first direction). In particular, the second sensor data can be determined for multiple downshifts, each performed by the driver by deflecting the shift lever 110 in a second direction. Thus, the second sensor data can be determined, showing a statistical distribution of the length 310 of the shift travel 210 of the shift shaft 207 during each downshift performed by the driver of vehicle 100.

[0069] The method 400 further includes: based on first sensor data and second sensor data, verifying the position of the shift lever 110, and in particular verifying the suitability of the position of the shift lever 110 for the driver. For example, it can be verified whether the position allows the driver of the vehicle 100 to comfortably perform not only upshifting but also downshifting. To this end, for example, it can be verified whether the length 310 (average value) of the shift travel 210 is high enough to perform not only upshifting but also downshifting.

[0070] The measures described in this article can improve the comfort and reliability of the gear shifting process using a foot-operated gear lever.

[0071] This invention is not limited to the embodiments shown. In particular, it should be noted that the specification and drawings are intended to illustrate only the principles of the proposed methods, apparatus, and systems.
