Of the reference pedal acting force corresponding to the crank rotation angle θb of the reference data table closest to the crank rotation angle θa detected in step S4. And a difference from the “reference pedal acting force value”) is calculated and stored in a predetermined area of the RAM 13c.

  In step S6, it is determined whether to display the measurement pedal action force and the reference pedal action force related to the difference calculated in step S5. Specifically, it is determined whether or not the difference between the pedal action force values calculated in step S5 is equal to or greater than a predetermined reference value K. The reference value K is not particularly limited, but is set to 30 (N) in the present embodiment. In step S7, if it is displayed in step S6, that is, if it is determined that the difference in pedal acting force value is greater than or equal to the reference value K, the process proceeds to step S8, and is not displayed in step S6, that is, pedal acting force value. Is determined to be less than the reference value K, the process proceeds to step S9.

  In step S8, a difference vector obtained by subtracting the reference pedal action force from the measurement pedal action force, which is a vector, is calculated, and difference vector data indicating the difference vector is stored in the difference vector data storage area of the RAM 13c. Note that the crank rotation angle θa represented by the crank rotation angle data acquired in step S4, the pedal action force rotation direction component magnitude Fx represented by the pedal action force rotation direction component data, and the pedal action represented by the pedal action force rotation direction component data. Based on the magnitude Fy of the force rotation direction component, it is possible to calculate the direction of the measurement pedal acting force at the crank rotation angle θa. In addition, among the crank rotation angles of the reference data table acquired in step S3, the pedal action force value data corresponding to the crank rotation angle θb closest to the crank rotation angle θa is the magnitude of the reference pedal action force. The pedal action force direction data corresponding to the rotation angle θb is the direction of the reference pedal action force. A difference vector is calculated based on the magnitude and direction of each pedal action force.

  When the difference vector is stored, the difference vector is stored as a difference vector for the crank rotation angle θb closest to the crank rotation angle θa. The difference vector storage area is divided into 360 in association with the crank rotation angle θb, and the above zones are associated therewith.

  In step S9, it is determined whether or not the crank B31 has made one revolution. It is determined whether or not the crank rotation angle indicated by the crank rotation angle data acquired in step S3 newly exceeds 360 °. If it is determined in this step that the crank rotation angle is not equal to or greater than the predetermined value, the process proceeds to step S4. If it is determined that the crank rotation angle is equal to or greater than the predetermined value, the process proceeds to step S10.

  In step S10, the difference vectors for each zone are combined, and the magnitude and direction of the difference vector are stored in the difference vector data storage area of the RAM 13c. The difference vector data storage area is divided into six in association with the zone type and the component (size / direction) of the difference vector. That is, the difference vector data storage area is composed of a power zone portion for the power zone, a pulling zone portion for the pulling zone, and a kicking zone portion for the kicking zone, and each portion represents a difference indicating the size of the difference vector. A difference magnitude part that stores vector magnitude data and a difference direction part that stores difference vector direction data representing the direction of the difference vector are configured.

  In step S11, in order to display the measurement pedal action force and the reference pedal action force determined to be displayed in step S7 and the combined difference vector of each zone on the display unit 12, A drawing creation process for creating the following data is performed.

  Specifically, first, reference circle object data relating to the left crankshaft B311 is created, stored in the reference circle object area of the RAM 13c, and partition line object data for expressing the power zone, the pulling zone, and the kicking zone. Is stored in the partition line object area of the RAM 13c. As shown in FIG. 9, the reference circle object is divided into three in the circumferential direction by the partition line object, and a power zone, a pulling zone, and a kicking zone are expressed. As described above, the reference circle object is associated with the crank rotation angle θb of the reference data, and the range of the crank rotation angle in which each zone is set, that is, the crank rotation angle indicated by the partition line object is For example, it is stored in advance in the ROM 13b as a table.

  Next, the measurement pedal action force object data related to the measurement pedal action force and the reference pedal action force object data representing the reference pedal action force determined to be displayed in step S7 are created and stored in a predetermined area of the RAM 13c. As shown in FIG. 9, both pedal acting force objects share a starting point, and the starting point is arranged at the position of the crank rotation angle θb associated with the reference pedal acting force on the circumference of the reference circle object. Further, the mode of the vector representing the reference pedal acting force and the mode of the vector representing the measuring pedal acting force are different so that the reference pedal acting force object and the measuring pedal acting force object can be distinguished. Specifically, the line width and the arrow shape are different between the two vectors. In the present embodiment, the reference pedal acting force vector is thicker.

  Finally, synthesized difference vector object data is created for each zone and stored in the synthesized difference vector object storage area of the RAM 13c. The combined difference vector object storage area includes a power zone portion for storing combined difference vector object data for power zones, a pulling zone portion for storing combined difference vector object data for pulling zones, and a combined difference vector for kicking zones. It consists of a kick-out zone that stores object data. The composite difference vector object for each zone is arranged around the center of the portion where the corresponding zone is expressed. As shown in FIG. 9, the composite difference vector object is composed of white arrows, the direction of the arrow indicates the direction of the composite difference vector, and the size of the arrow indicates the size of the composite difference vector. . In the present embodiment, five sizes of the combined difference vector are set, and the range of the size of the combined difference vector is set for the size of each combined difference vector object.

  In step S12, an information display that transmits the data that is the basis of the drawing created in step S8 to the display unit 12 and displays (informs) information such as a comparison between the reference pedal action force and the measurement pedal action force and pedaling improvement guidance. Process.

  In step S13, it is determined whether or not the measurement end condition is satisfied and the measurement can be ended. In the present embodiment, the measurement end condition is satisfied when a signal indicating a button operation for the end of the measurement is transmitted. If it is determined in this step that the measurement end condition is not satisfied, the process proceeds to step S4. If it is determined that the measurement end condition is satisfied, the main process is ended.

  As described above, the pedaling correction assisting device displays the reference pedal acting force and the measuring pedal acting force, and the relationship between the reference pedal acting force and the measuring pedal acting force is indicated. It is possible to understand the difference from the measured pedal action force and correct the way of applying a load to the pedal, that is, pedaling related to the pedal action force. Also, by calculating the crank rotation angle and displaying the relationship between the reference pedal action force and the measurement pedal action force in association with the crank rotation angle, it is possible to grasp pedaling related to the pedal action force more accurately. . This is because the rotation of the crank and the movement of the foot that generates the pedal action force are linked and synchronized. Furthermore, when the absolute value of the difference between the magnitude of the reference pedal acting force and the magnitude of the measuring pedal acting force is equal to or greater than a predetermined reference value, the relationship between the reference pedal acting force and the measuring pedal acting force is notified. That is, when pedaling related to the pedal action force is not good, the relationship is notified. In this way, by keeping the content of the notification to the minimum necessary, the trouble of organizing the information can be saved and the pedaling can be easily corrected.

  In addition, by reporting a combined differential vector that is a combination of the difference between the reference pedal acting force and the measuring pedal acting force that is a vector, pedaling correction is guided, so that pedaling can be corrected easily and accurately. it can. In addition, one rotation of the crank is related to pedaling components (power zone, pulling foot, kicking out) and divided into a plurality of divisions, and the combined difference vector is notified for each divided predetermined range, thereby further accurately pedaling Can be configured. In addition, it is easy to grasp the pedaling state by expressing the relationship between the reference pedal action force and the measurement pedal action force with a graphic using a display device.

  The cycle computer 1, the crank rotation angle detection sensor 2, the rotation direction component detection sensor 3, and the radial direction component detection sensor 4 constitute the pedaling correction assisting device of the present invention. Further, the rotational direction component detection sensor 3, the radial direction component detection sensor 4, the pedal acting force rotational direction component information acquisition unit S32, and the pedal acting force radial direction component information acquisition unit S33 constitute the actual measurement value acquisition unit of the present invention.

(Other embodiments)
In the first embodiment, the reference data is composed of a reference data table. However, the reference data may be composed of a predetermined calculation expression representing the relationship between the crank rotation angle and the magnitude of the pedal action force. Thereby, since the accuracy of the reference data is increased, the pedaling can be corrected accurately. In addition, an increase in the amount of data stored in advance in the reference information storage unit such as the ROM 13b can be suppressed.

  In the first embodiment, the crank rotation angle of the reference data table is set at intervals of 1 °, but the width of this interval is not limited and is set appropriately.

  In the first embodiment, there is one type of reference data table as reference data, but a plurality of types of reference data tables may be set. In this case, for example, the reference data table is associated with specific information related to the pedal action force such as the size of the tire of the bicycle B, the body shape / sex / age / driving skill of the driver, and the combination of these specific modes. Reference data can be different. Since the pedal action force varies depending on the characteristics inherent to the bicycle and the driver, the pedaling can be corrected accurately by making the reference data accurate. The unique information in this case is input in the unique information processing in step S1, for example.

  Furthermore, the reference pedal acting force also varies depending on the external environment that can change during traveling, such as the wind direction, the driver's posture, the gear ratio, the ground gradient, and the driving situation of the driver / bicycle. Therefore, by setting the external environment and the driving situation of the driver / bicycle in association with the reference data, detecting the driving situation while driving, and selecting the reference data based on the detection result, the reference data becomes more accurate. The pedaling can be corrected more accurately. In this case, the reference data can be stored and accumulated in storage means such as the RAM 13c, and the reference data can be corrected based on these data. Thus, by correcting the reference data specific to the driver / bicycle, the accuracy of the reference data is improved, and pedaling can be corrected more accurately. In this case, since the acquisition of the reference data is automated for the driver, it is possible to prevent the operability of the pedaling correction assisting device 100 from being deteriorated.

  In the first embodiment, the reference target for the determination of the success or failure of the display of the reference pedal action force and the measurement pedal action force is only the pedal action force value that is the magnitude of the pedal action force, but is not limited thereto. For example, the determination reference object can be set only for the direction of the pedal action force, or both the direction of the pedal action force as a vector and the pedal action force value. Further, the determination related to the display of the reference pedal action force and the measurement pedal action force is performed every time the crank B31 rotates once, but is performed once every time the crank B31 rotates, that is, the crank B31 rotates a predetermined number of times. You can then update the display content. Alternatively, this determination can be performed once every predetermined time. Thereby, the burden of the control part 13 is reduced.

  In the first embodiment, the improvement guidance is calculated and displayed every time. However, as with the display of the reference pedal action force and the measurement pedal action force, the improvement guide is displayed when a predetermined condition is satisfied. You can also. For example, in one rotation of the crank, when the determination result indicating that the reference pedal action force and the measurement pedal action force are displayed is a predetermined number of times or more, the information is displayed for all zones. It is also possible to determine whether a predetermined condition is satisfied for each zone. Further, similarly to the display of the reference pedal action force and the measurement pedal action force, it is also possible not to display when the difference between the pedal action force values is less than the reference value.

  In the first embodiment, three types of zones are set, but the types of zones are not limited and are set as appropriate. Further, for example, it is possible to select a zone in the information input process in step S1. In this case, the good zone and the poor zone are different, and it is possible to respond to the desire to display only the poor zone. In the first embodiment, the zone range is fixed, but may be changed. For example, ranges such as a power zone, a pulling zone, a kicking zone, and the like vary depending on the gradient of the ground. Therefore, the range of the zone is associated with the gradient of the ground, and the gradient of the ground is detected. Thereby, the precision of improvement guidance improves and it can correct pedaling more correctly.

  In the first embodiment, the target data is stored in advance in the ROM 13b. However, the target data is stored in a storage medium suitable for the pedaling correction assisting device 100 such as an SD card, and the storage medium I / F 13 is used. You may make it acquire via. Further, in the information input process in step S1, by inputting the user ID, the target data stored in the server or the like and the specific information such as the driver are acquired via the communication I / F 13. May be.

  Furthermore, the display mode of the pedaling force improvement guidance and the pedaling improvement guidance is not limited to the first embodiment. For example, the size of the combined difference vector can be classified by the color and shape of the combined difference vector object.

  In the first embodiment, the ideal and actual comparison of pedal action force on both feet and the display of pedaling improvement guidance are displayed, but only one of the feet can be displayed. Further, for example, in the information input process in step S1, it may be selected which foot is to display the ideal and actual comparison of pedaling force and the pedaling improvement guidance. In addition, display contents can be selected in the information input process in step S1.

  Further, in the first embodiment, the pedal computer force ideal and reality and pedaling improvement information is displayed by the cycle computer 1, but the pedal force ideal and reality and pedaling are applied by application software of a mobile terminal such as a mobile phone. It is also possible to judge and display improvement information. In this case, the mobile terminal may be installed on the bicycle B or carried by the driver. Steps S5 to S12 may be executed by a fixed terminal such as a PC installed at home or the like. In this case, necessary data such as crank rotation angle data, pedal action force rotation direction component data, and pedal action force radial direction component data are recorded on a memory card or the like via the storage medium I / F 13d of the cycle computer 1, for example. Save to a medium and import from a recording medium to a fixed terminal. Further, the data is transmitted to the fixed terminal via the communication I / F 13f of the cycle computer 1 and is taken into the fixed terminal.

  When steps S5 to S12 are executed on the fixed terminal, a program for performing these processes is incorporated even if a storage medium such as a CD storing a program for performing these processes is read into the fixed terminal. The downloaded application may be downloaded from the server. Steps S5 to S12 may be executed on the server via a mobile terminal or a fixed terminal.

  Further, the pedaling correction assisting device means of the present invention is not limited to a bicycle traveling on the road, but is a non-exercise exercise bike installed in a sports gym or the like, or a ship that is manually driven and driven by a pedal (for example, a swan) The present invention can be applied to a vehicle that rotates a crank connected to a pedal such as a boat.

  Moreover, in Embodiment 1, the notification execution means of the present invention is configured by a liquid crystal display device, but the notification execution means is not limited to this. For example, other display devices such as a CRT, a plasma display, and an organic EL display may be used. Further, the notification execution means may be an acoustic device such as a speaker or a lighting device such as a light instead of the display device.

  In the first embodiment, one rotation of the crank B31 is divided and a combined vector is displayed for each zone. However, information displayed for each zone is not limited to the combined vector. You may display the difference vector which has the largest magnitude | size within each zone.
