=== Embodiment ===

Hereinafter, an electric assist bicycle equipped with an electric assist bicycle motor unit according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an outline of an electrically assisted bicycle 1 according to an embodiment of the present invention. As shown in the figure, the main part of the electrically assisted bicycle 1 is composed of a body frame 2 made of a metal tube, like a normal bicycle. The body frame 2 includes a front wheel 3, a rear wheel 4, The handle 5 and the saddle 6 are attached in a known manner.

Further, a drive shaft 7 is rotatably supported at the lower center portion of the body frame 2, and pedals 9 are respectively attached to the left and right end portions via crank rods 8. A sprocket 10 is coaxially attached to the drive shaft 7 via a one-way clutch (not shown) for transmitting only the rotation corresponding to the forward direction of the vehicle body. Between this sprocket 10 and a rear wheel power mechanism 11 provided at the center of the rear wheel 4, a chain 12 that can be rotated in an endless state is stretched.

The electrically assisted bicycle 1 of the present embodiment is an electrically assisted bicycle motor unit that performs control for assisting the pedaling force at a predetermined assist ratio (auxiliary power / stepping force) determined based on at least the traveling speed and the pedaling force to depress the pedal 9. Hereinafter, it is simply referred to as “motor unit”) 13. In this embodiment, the control of the electric assist bicycle 1 and the resultant force operation of the electric force and the pedaling force are executed by the electric assist motor unit 13 that is an auxiliary power mechanism.

FIG. 2 is a block diagram showing an outline of the electric assist motor unit 13 provided in the electric assist bicycle 1. The motor unit 13 according to the present embodiment includes a microcomputer 14 that collectively controls the electronic processing of the entire electrically assisted bicycle 1 and an assist associated with the assist ratio that is communicably connected to the microcomputer 14. A motor unit board 16 including a storage unit 15 for storing a data table indicating the amount, an electric motor 17 capable of PWM control, a battery 18 for supplying power to the electric motor 17, and a traveling speed of the electric assist bicycle 1 are detected. A speed detecting unit 19 including a speed sensor for detecting the pedaling force and a pedaling force detecting unit 20 including a pedaling force sensor for detecting the pedaling force.

The microcomputer 14 calculates the traveling speed from the input signal from the speed detection unit 19, calculates the pedaling force from the input signal from the pedaling force detection unit 21, and performs electronic processing for determining the assist ratio based on a predetermined algorithm. . At this time, the microcomputer 14 acquires information (customized data) indicating the assist amount from the data table stored in the storage unit 15.

Next, in order to instruct the electric motor 17 to generate the auxiliary power corresponding to the assist amount associated with the determined assist ratio, the microcomputer 14 sequentially outputs PWM commands corresponding to the auxiliary power.

FIG. 3 shows an example of a data table stored in the storage unit. In the data table, for example, a plurality of cells are arranged in a matrix in the vertical and horizontal directions, the traveling speed is set on the vertical axis, and the pedaling force is set on the horizontal axis. When a predetermined pedaling force F generated by depressing the pedal 9 is detected at a predetermined traveling speed V, a cell (in FIG. 3) located at the intersection of the predetermined traveling speed V and the predetermined pedaling force F is detected. A value of the assist amount referred to when outputting a PWM command for controlling the electric motor 17 is assigned to a numerical value (0 to 255) of 1 byte, for example. Thus, in the present embodiment, the cell is a frame arranged in a matrix in which the assist amount uniquely determined in association with the traveling speed and the pedaling force is written, and is written and changed on the customization screen. It is possible.

Since the assist power at each traveling speed and each treading force of the electrically assisted bicycle 1 is set according to the assist amount of each cell of the data table, by changing this data table, the user of the electrically assisted bicycle 1 can Different responses can be obtained with respect to the depression force of the pedal 9 of the assist bicycle 1.

Further, in the electrically assisted bicycle 1 of the present embodiment, a plurality of types of data tables (preset data) are stored in the storage unit 15 of the motor unit 13 as data tables set in advance as initial setting values.

Data tables stored as initial setting values include, for example, a general normal mode data table, an eco mode data table with reduced power consumption, and a turbo mode with a larger auxiliary power than the normal mode. There is a data table for the high turbo mode in which the auxiliary power is set larger than the turbo mode. In addition, a data table for non-assist mode in which “0” is written in all cells is also stored.

For this reason, the electric assist bicycle 1 can be set so that the user can obtain different assist responses with respect to the pedal effort by setting the data tables for these five modes in advance. In addition, by changing the set mode, it is possible to vary the assist response to the pedal effort for one electrically assisted bicycle 1. Thus, in the present embodiment, the mode is a part or all of a plurality of setting modes set in advance so that different assist responses can be obtained.

The electric assist bicycle 1 of the present embodiment further has a function of customizing the data table so that each user of the electric assist bicycle 1 can obtain an assist response with respect to the pedaling force, which is more preferable.

For example, as shown in FIG. 4, the electrically assisted bicycle 1 is connected to a mobile terminal 21 or a PC, and the data table can be customized by communicating with the connected mobile terminal 21 or a PC. In the following description, an example in which the mobile terminal 21 is connected will be described. At this time, the connection between the portable terminal 21 and the motor unit 13 may be a wired connection using a USB cable or the like, or a wireless connection using Bluetooth or the like.

The portable terminal 21 includes a display unit 21a capable of displaying a data table stored in the storage unit 15 of the motor unit 13 in a matrix as shown in FIG. 3, an operation unit 21b capable of changing the data table, It has the communication part (not shown) which can communicate with the memory | storage part 15 by radio | wireless. The mobile terminal 21 of the present embodiment includes a touch sensor on the display unit 21a, and can touch and slide the screen on the display unit 21a to operate the mobile terminal 21.

The mobile terminal 21 can switch and display three screens on the display unit 21a: a setting screen for setting and changing settings, a data table screen for displaying a data table, and a customization screen for customizing the data table. is there. FIG. 5 shows an example of a display screen of a tool used when writing set data to the electric assist motor unit 13, FIG. 6 shows an example of a data table screen, and FIG. 7 shows an example of a customization screen. The tool can be used to write setting data to the electric assist motor unit 13 by using a specific dealer or user.

As shown in FIG. 5, the display screen when setting data is written is, for example, an electric assist bicycle such as a GD indicating the distance traveled by the electric assist bicycle 1 when the pedal 9 of the electric assist bicycle 1 is rotated once, a tire diameter, and the like. 1 and the setting state of the motor unit 13 such as the set data table mode are displayed, and a setting operation unit 21f for changing the displayed setting items is arranged. . These values are set on a customization screen (FIG. 7) described later.

The data table screen displays the data table values that have been set. For example, a data table as shown in FIG. 6 is displayed on the display unit 21 a of the mobile terminal 21.

The displayed data table is arranged in such a way that the traveling speed increases in the vertical direction from top to bottom, and the pedaling force increases in the horizontal direction from left to right. And a plurality of cells arranged in a matrix form. In each cell, a value (customized data) indicating the assist amount associated with the traveling speed and the pedaling force is written.

In the data table, the area where the customized data indicating the assist amount is arranged in a matrix is colored, and each cell in which the customized data is written has a density corresponding to the size of the written assist amount. Is different. Specifically, the density increases as the assist value increases, and the density decreases as the assist value decreases.

As shown in FIG. 6, the data table is divided into seven areas. For example, the low speed region where the traveling speed is low forms a single region regardless of the pedal effort. The medium speed area and the high speed area of the traveling speed are each divided into three areas where the magnitude of the pedal force is different, for example, a small pedal force area, a middle pedal force area, and a large pedal force area. In the following, among the seven areas, the area associated with the low speed area is referred to as the first area, the area associated with the medium speed area and the small pedal effort area is referred to as the second area, and the medium speed area and the medium pedal effort area. The associated region is the third region, the region associated with the medium speed region and the large pedal force region is the fourth region, the region associated with the high speed region and the small pedal force region is the fifth region, and the high speed region. The area associated with the middle pedal effort area will be described as the sixth area, and the area associated with the high speed area and the large pedal effort area will be described as the seventh area. These seven regions correspond to a plurality of customization regions in which a plurality of assist amounts associated with a plurality of types of pedaling forces and a plurality of types of travel speeds can be set. In the present embodiment, a region is a matrix cell group (a plurality of cells) that is formed by dividing a data table and forms the data table.

As shown in FIG. 7, the customization screen includes mode-specific operation units 21c corresponding to the four modes except for the non-assist mode described above. The operation unit 21c for each mode is color-coded according to each of the four modes. For example, the eco mode is color-coded such as sax, normal node is green, turbo mode is orange, and high turbo mode is red.

The operation unit 21c for each mode on the customization screen includes an operation unit 21d for each area for changing the assist amount written in all the cells included in each of the seven areas as a whole, and an upper limit value of the traveling speed. A speed upper limit operation unit 21e for setting is arranged. The operation units 21d for each of the seven areas in each mode are arranged so as to have the same positional relationship as the arrangement of the seven areas of the data table.

The region-specific operation unit 21d and the speed upper limit value operation unit 21e are each displayed as a slide bar that can be moved in the vertical direction. By operating the slide bar through the touch sensor, the region-specific operation unit 21d has four stages. The speed upper limit value operating unit 21e can be changed in six stages. Here, an example in which the area-specific operation unit 21d is a slide bar that can be set in four stages has been described, but a stepless slide bar may be used. In addition, it is possible to provide an input auxiliary unit such as a text box in which a numerical value can be directly input and an increment button in which the assist amount can be changed by “1”.

The four-stage setting of the operation unit 21d for each region is set, for example, by the ratio of the current supplied to the electric motor 17. More specifically, the maximum value of the current value set for each region and supplied to the electric motor 17 is determined in advance. When the step value “4” is set, the maximum current value is supplied to the electric motor 17. When the step value “3” is supplied, 80% of the maximum current value is supplied to the electric motor 17. When the step value “2” is set, the maximum current value 60 is set. % Current is supplied to the electric motor 17, and when the step value “1” is set, 40% of the maximum current value is set to be supplied to the electric motor 17. Then, by changing the operation unit 21d for each area, the value indicating the assist amount (customized data) written in the cell arranged in the area of the data table corresponding to the operation unit 21d for each area is the step value. It changes according to the ratio. The current value at each step value may be a value other than 80%, 60%, and 40% of the maximum current value as described above.

The normal mode data table, the eco mode data table, the turbo mode data table, and the high turbo mode data table each have a reference data table. The data table serving as a reference for each mode is set, for example, to a step value “2” for each of the operation units 21d for each region. When the slide bar is moved to “1”, all of the corresponding regions in the data table are displayed. The value of the cell is rewritten to a value set to the step value “1”, and the electric motor 17 is changed so that a current of 40% of the maximum current value is supplied.

For this reason, the value of the assist amount of all the cells in the desired area is changed by performing a sliding operation while pressing the slide bar of the operation unit 21d for each area arranged at the same position as the desired area to be customized through the touch panel. Is done. Data for rewriting all cells in each region is stored in the storage unit 15 for each mode and step value of each region, and information indicating the region to be changed and the step to be changed is operated for each region. By inputting from the unit 21d, the stored data is written and the data table is changed.

In the motor unit 13 of the present embodiment, for the low speed region (first region), the medium speed region and the high speed region are divided into three regions, that is, a small pedal force region, a medium pedal force region, and a large pedal force region. This is not divided, because when the driving speed is low, that is, when the power-assisted bicycle is activated (when starting rowing), the amount of current is large. This is because an unexpectedly large load may be applied to the electric motor 17 and may cause a failure. Also, in the low speed region, the pedaling force pattern is uniform, and it is less meaningful to divide as in other regions.

The customization screen includes a GD setting unit 21f and a tire diameter setting unit 21g. GD is the distance that the bicycle travels while the pedal rotates once. By setting the GD and the tire diameter, it is possible to set a correct assist amount with respect to the traveling speed and to obtain a good assist feeling. In addition, the customization screen according to the present embodiment includes a motor unit feeling data reading button, a feeling data file reading button, a reeling data file saving button, and feeling data motor unit writing around the operation unit 21c for each mode. In addition to buttons, buttons such as an end button are provided. In addition, this customization screen is specified by the work type, for example, Read target (designated when reading the feeling data of the motor unit 13 to the application) button, Import (designated when reading the feeling data output in the past as a file) ) Button and a New (designated when creating a new) button. In addition, this customization screen allows you to set device information such as motor, battery, switch, device control program, etc., as well as travel status information such as remaining battery power, travel speed, travel distance, travel time, travel route, and driver physical information. It is possible to set which information among vital information such as calorie consumption, pulse, heart rate, etc. can be displayed on the display unit 21a.

Next, a method for customizing the data table of the electrically assisted bicycle 1 will be described. The customization of the data table of the electric assist bicycle 1 shown below is realized by executing a program stored in the storage unit 15 or the portable terminal 21.

The motor-assisted bicycle 1 is connected to a motor unit 13 and a portable terminal 21 in which an application program for customizing the motor-assisted bicycle 1 is stored in a factory or the like at the time of manufacture. Here, the application program may be stored in the storage unit 15 of the motor unit 13. Examples of the mobile terminal 21 include a mobile phone, a PC, and a tablet.

Then, the application program of the connected mobile terminal 21 is executed, and the setting operation unit 21f arranged on the setting screen is operated, thereby being associated with the four modes stored in the storage unit 15 of the motor unit 13. One of the selected data tables is selected and set as default. Thereafter, the power-assisted bicycle 1 is shipped with the mobile terminal 21 disconnected.

The shipped electric assist bicycle 1 is in a state where the data table can be customized by a dealer or a user, and the data table can be customized according to the user's request.

A user who wants to change the data table or a dealer who has received a request from the user connects the motor unit 13 of the electric assist bicycle 1 and the portable terminal 21 in which an application program for customization of the electric assist bicycle 1 is stored. To do.

The application program of the connected mobile terminal 21 is executed, and a customization screen is displayed on the display unit 21a of the mobile terminal 21. At this time, the area-specific operation unit 21d and the speed upper limit value operation unit 21e corresponding to the four modes are displayed in different colors on the display unit 21a. At this time, the region-by-region operation unit 21d and the speed upper limit value operation unit 21e corresponding to the mode set by default are highlighted or a predetermined portion is marked, for example, so that the electric assist bicycle 1 The mode set (preset) in the motor unit 13 is shown.

A customizer who is a user or a dealer who has received a request from the user first checks the set mode, and if there is a need to change, the display is switched to the setting screen, and the setting operation unit 21f on the setting screen is displayed. Then, a desired mode is designated and rewritten to a data table corresponding to the desired mode, and the display is switched again to the customization screen. Here, the data table of the preset mode and the data table rewritten to the desired mode are hereinafter referred to as a preset data table.

Next, the customizer operates the speed upper limit operation unit 21e as necessary to change the speed upper limit value. Normally, the upper speed limit is set based on regulations. For example, when a child or an elderly person uses the motor, by operating the slide bar of the speed upper limit operation unit 21e as necessary, the motor Information on the speed upper limit value stored in the unit 13 is rewritten.

Next, the customizer operates the slide bar of the operation unit 21d for each area corresponding to the area to be changed corresponding to the set mode. For example, a case where the preset mode or the changed mode is the normal mode and the third area is customized to the step value “4” will be described. FIG. 8 is a flowchart showing a process for customizing the data table.

The slide bar of the operation unit 21d for each area in the third area, which is associated with the third area in the normal mode and located at the reference stage value “2”, is moved to the position of the stage value “4”. By this operation, a signal indicating the normal mode, the third region, and the step value 4 is sent to the motor unit 13. At this time, the motor unit 13 acquires change information for any one of the plurality of areas (here, the third area) (change information acquisition step S1). Based on the input signals, the motor unit 13 sets the assist amount value stored in the storage unit 15 in association with the normal mode, the third area, and the step value 4 in the third area of the preset data table. The assist amount value is rewritten (assist amount changing step S2).

When the assist amount in any region of the preset data table (the third region in the present embodiment) is rewritten, the motor unit 13 is positioned at the boundary between the rewritten region and the adjacent region. Then, the optimization process is executed (assist amount optimization step S4). In the optimization process, by rewriting the assist amount in a certain area, the difference in the assist amount value between cells adjacent to each other between the rewritten area and the adjacent area is extremely large. This is a process to prevent it from happening.

More specifically, the step value indicated by the slide bar in the area where the assist amount has been rewritten is compared with the step value indicated by the slide bar in the area adjacent to the rewritten area (comparison step S3), which differs by one or more stages. In this case, the optimization process is executed. If there is no difference, the optimization process is not performed. In this regard, it is possible to perform the suiting process when the difference between the step values of the adjacent regions is two or more, and to prevent the optimization when the difference is one or less.

As described above, when the data in the third area is rewritten, the cells to be subjected to the optimization process are the first, second, fourth, and sixth adjacent to the changed third area. A cell located at the boundary with each region and arranged on the outermost periphery of the third region, for example, three cells up to two cells arranged inside the first region, and a first adjacent to the third region , Cells arranged on the outermost periphery of each of the second, fourth, and sixth regions, and three cells including cells arranged on the inner side of the two cells. Here, the number of cells serving as the boundary portion between adjacent regions is not necessarily three inward from the outermost peripheral cell.

In the optimization process, for example, a so-called moving average process is performed on each target cell. More specifically, the average value of assist amounts written in seven cells arranged in the vertical direction or the horizontal direction centering on one target cell is rewritten as a new assist amount of the target cell. Such arithmetic processing and rewriting processing are executed for each target cell. At this time, for example, an average value of 7 cells each in the vertical and horizontal directions around the target cell, that is, a total of 49 cells may be rewritten as a new assist amount. Note that the number of cells for calculating the average value is not limited to 7 or 49, and the cell that is the target may be appropriately set as a cell located at the boundary between the area where the data is changed and the adjacent area. .

The optimization process is performed on two regions that are adjacent to each other in the vertical direction and two regions that are adjacent to each other on the left and right sides so as to sandwich the region where the step value is changed.

According to the electrically assisted bicycle 1, the motor unit 13, the assist amount customizing device for the electrically assisted bicycle 1, the assist amount customizing method for the electrically assisted bicycle 1, and the assist amount customizing program for the electrically assisted bicycle 1 according to this embodiment. Since the data table referred to when the auxiliary power is applied can be changed, it is possible to realize the electrically assisted bicycle 1 that suits the feeling of preference by customizing the data table. In addition, the data table indicating the assist amount for assisting the pedaling force is divided into seven regions including a plurality of cells in which the assist amounts associated with a plurality of types of pedaling force and a plurality of types of travel speeds are written. Since it can be changed for each region, it is possible to customize more easily than when changing each of the plurality of assist amounts individually. That is, the user can change the assist amount of all the cells in a predetermined area at one time without making a complicated work of changing the assist amount written in each cell.

In addition, since the storage unit 15 of the motor unit 13 stores some or all of a plurality of types of preset data, it is possible to select and set preset data close to a feeling of preference. is there. Furthermore, by presetting the preset data closest to the preference in advance and changing to other preset data according to the preference after actually running, it is possible to customize according to the preference more easily. It is also possible to enjoy different types of settings by a simple change operation. Furthermore, the present electrically assisted bicycle 1 can be easily customized by changing the assist amount in each region in stages, using each stage as a guide. Thus, in the present embodiment, the preset data is information stored in advance in the storage unit 15, the mobile terminal and / or the server of the motor unit 13, and at least of all the operation units 21c for each mode. This means that all or part of the stage values have been determined.

In addition, when the assist amount of a predetermined area is changed, the assist amount written in a cell located at a boundary portion between the predetermined area and another adjacent region is optimized, so the assist amount is changed. It is possible to prevent the assist amount from changing suddenly at a boundary portion between the predetermined area and another area adjacent to the predetermined area. For this reason, when the user of the electrically assisted bicycle 1 pedals the pedal 9, it is possible to prevent a sense of incongruity that a sudden load fluctuation occurs.

In addition, as the optimization of the assist amount, moving average processing is performed on the assist amount written in a plurality of adjacent cells, so that the assist amount can be changed more smoothly at the boundary with other adjacent regions. It is.

Further, since the customization operation of the electric assist bicycle 1 is performed by the mobile terminal 21, the storage unit 15 is operated by viewing the data table displayed on the display unit 21 a of the mobile terminal 21 and operating the operation unit 21 b of the mobile terminal 21. It is possible to easily change the data table by communicating with. In addition, since the display unit 21a, the operation unit 21b, and the communication unit are all provided in the mobile terminal 21, the mobile terminal 21 can be separated from the electric assist bicycle 1, and the mobile terminal 21, the electric assist bicycle 1, It is possible to reduce the weight of the electrically assisted bicycle 1 by cutting off and to reduce the cost. Further, it can be easily customized without being connected to an external device by a cable or the like.

In the above embodiment, the example in which customization of the electrically assisted bicycle 1 is performed by wireless communication using the mobile terminal 21 has been described, but connection may be made using a cable. In this case, UART communication can be employed by using a dedicated cable. Further, not limited to the portable terminal 21, for example, it may be customized by connecting to a PC installed in a factory or the like. Furthermore, the display unit 21a, the operation unit 21b, and the communication unit may all be provided in the motor unit 13 of the electric assist bicycle 1. In this case, complicated labor such as connecting the electric assist bicycle 1 and an external device with a cable or pairing for wireless connection is unnecessary. For this reason, it is possible to change the data table more easily. As described above, the motor unit 13 or the motor unit 13 and the mobile terminal 21 each including the display unit 21a, the operation unit 21b, and the communication unit correspond to an assist amount customization device of the electric assist bicycle 1.

Note that specific customization is performed using a PC as an example. For example, each procedure of reading a target, reading a file, saving data, outputting a C language file, writing a target, and editing feeling data is independent. It is designed to be executed as a subroutine.

Here, “target reading” is an assist feeling stored in the storage unit 15 of the motor unit 13 after establishing communication by transmitting and receiving a checksum in an interactive manner between the motor unit 13 and the PC. This is a subroutine for transmitting data to a PC. “File reading” is a subroutine for extracting feeling data (binary saved data) saved in the PC to a customization application program. The binary saved data includes a checksum and each cell of each mode in the program. Assist amount (current value), position information on the travel speed limit of each slider in the program, base program number in the program, GD / tire diameter information, so-called rearward presence / absence information. “Data saving” is a subroutine for saving the feeling data as binary data in the PC. “C language file output” is a subroutine for reading the binary data, outputting it as C language text data, and storing it. “Target writing” is a subroutine for writing the feeling data of the PC to the storage unit 15 of the motor unit 13 after communication is established in the above-described interactive format. “Feeling data editing” is, for example, a subroutine including a subroutine for a magnification conversion function in addition to the optimization function according to the present invention. The “optimization function” creates a temporary buffer of the same size as the assist feeling data in the customization application program, calculates the moving average of the row for each cell, and stores the result in the temporary buffer. This is a subroutine for performing up to the row, then calculating the column moving average for each cell, and storing the result in the temporary buffer until the last row. On the other hand, the “magnification conversion function” is a subroutine for creating a temporary buffer of the same size, obtaining the magnification, multiplying the selected cell by the magnification, and storing the result in the temporary buffer for all the selected cells. It is.

In addition, the area-specific operation unit 21d provided for each of the classified customization areas is laid out in the same arrangement as the arrangement of the respective customization areas in the data table, so that the intuitive operability is excellent. It is possible to suppress mistakes such as operating the wrong area. For this reason, it is excellent in operability.

Furthermore, since the magnitude of the assist amount is indicated by color shading on the display unit 21a, it is possible to intuitively recognize the magnitude of the assist amount set by looking at the display unit 21a. For this reason, it is possible to provide the electrically assisted bicycle 1 with more excellent operability.

In the above embodiment, the example in which the data table is customized by connecting to the motor unit 13 provided in the electrically assisted bicycle 1 has been described. However, the present invention is not limited to this. For example, the motor unit 13 may be detachable, and the motor unit 13 may be customized as a single unit, for example, in a factory or a dealer.

Moreover, in the said embodiment, although the customizer input from the portable terminal 21 and demonstrated the example which changes the assistance amount of a predetermined area | region, it is not restricted to this, For example, the information of the vital sensor attached to the user is provided. The assist amount may be further corrected based on the input vital sensor information. For example, it is provided with a vital sensor that detects the heart rate of a user riding on the electrically assisted bicycle 1, and data set when a signal indicating a heart rate higher than a predetermined heart rate is input from the vital sensor. The data table may be rewritten to a data table having a larger assist amount than the table. At this time, the amount of assist to be rewritten may be the entire data table or only a predetermined area.

Note that the display unit 21a includes any of the remaining battery level, travel speed, travel distance, travel time, travel status information such as travel route, driver physical information, vital information such as calories consumed, pulse, heart rate, and the like. It is preferable that the information can be displayed.

Further, a server 22 that stores a value (customized data) indicating an assist amount that is rewritten when customized as described above may be provided so as to be accessible via a public network or the like.
