(4) Calculation of Air Resistance and Absolute Wind Speed Next, a method of calculating the air resistance and absolute wind speed executed by the control unit 7 of the cycle computer 1 will be specifically described. Hereinafter, the moving power of the bicycle (that is, the amount of change in potential energy or the power of work against gravity) is referred to as "moving power Pm", and the power of work with rolling resistance is referred to as "rolling resistance Pr". The power of work caused by mechanical drive loss of a bicycle is called "drive loss Pdls", and the power of work caused by air resistance is also called "air resistance Pa".

In this case, the pedaling power Pp is the sum of the powers of the drag forces applied to the bicycle, that is, the moving power Pm, the rolling resistance Pr, the drive loss Pdls, and the air resistance Pa, as shown in the following equation (1). Is equal to the sum of.

Then, by modifying the equation (1) with respect to the air resistance Pa, the following equation (2) is obtained.

Further, the moving power Pm is calculated by using the driver's weight "mb", the bicycle weight "mc", the gravity acceleration "g" (≈9,81 [m / s ² ]), the gradient θ, and the velocity V. It is expressed by the equation (3) of.

Further, the rolling resistance Pr is represented by the following general formula (4) using the rolling resistance coefficient “Crr”, the weight mb, mc, the gravitational acceleration g and the velocity V.

Further, in this embodiment, the drive loss Pdls is regarded as “0” because it is negligibly small as compared with other elements. Therefore, assuming that the equations (3) and (4) are substituted into the equation (2) and the drive loss Pdls is set to "0", the air resistance Pa is expressed by the following equation (5).

Therefore, the control unit 7 can suitably calculate the air resistance Pa by storing the information corresponding to the equation (5) in the storage unit 4 or the like in advance. In this case, the control unit 7 stores in advance in the storage unit 4 based on the pedaling power Pp output by the pedaling sensor 51, the speed V output by the speed sensor 53, the gradient θ output by the tilt sensor 54, and the user input. The air resistance Pa is calculated from the equation (5) using the obtained coefficients Crr, weight mb, and mc. The control unit 7 may acquire the weights mb and mc from the driver's mobile terminal via the communication unit 6 by data communication, or may acquire the weights mb and mc by receiving the user input by the input unit 3. Further, when the gradient information is stored in the map data 41, the control unit 7 may acquire the gradient θ by referring to the map data 41 based on the current position. Further, the control unit 7 may set the drive loss Pdls to a predetermined value instead of considering the drive loss Pdls as 0, or may calculate the drive loss Pdls based on the output of the sensor group 5.

The air resistance Pa is the air resistance coefficient "Cd", the front projected area "A" which is the area where the moving body (that is, the driver and the bicycle) is projected on the vertical surface perpendicular to the ground, and the wind velocity relative to the bicycle. using "V _all" and air density "ρ", it is expressed by the following equation (6).

FIG. 6 is a diagram schematically showing the front projected area A. The front projected area A may be a value stored in the storage unit 4 in advance, or may be a value calculated based on the height of the driver, the type information of the bicycle, etc. according to the description of the international publication number WO2011 / 158365. Good. The relative wind velocity V _all, as shown in the following equation (7), the absolute wind speed an absolute wind speed "V _wind", corresponds to the sum of the velocity V of the bicycle.

Here and rearranging the equation (6) representing the air resistance Pa the absolute wind speed _{V wind} is an expression (7), the absolute wind speed _{V wind} is represented by the following equation (8).

Therefore, the control unit 7 preferably stores the information corresponding to the equation (8) in the storage unit 4 or the like in advance, so that the absolute wind speed V _wind is preferably used by using the air resistance Pa calculated based on the equation (5). Can be calculated in. In this case, the control unit 7 uses the speed V output by the speed sensor 53, the air resistance coefficient Cd and the air density ρ stored in advance in the storage unit 4, etc., and the above-mentioned front projection area A. The absolute wind speed V _wind is calculated from 8). The control unit 7 calculates the air resistance Pa based on the equation (5), and instead of calculating the absolute wind speed V _wind from the equation (8) using the calculation result, the air resistance Pa of the equation (8) is used. The absolute wind speed V _wind may be calculated by referring to the equation to which the equation (5) is substituted.

In general, the "wind speed" in the ground meteorological observation indicates the wind speed for 10 minutes at a height of about 10 m above the ground, and the "instantaneous wind speed" is the average of 3 seconds in the sample every 0.25 seconds. Indicates the wind speed. Therefore, the control unit 7 may calculate the instantaneous wind speed and the wind speed according to the above definition. In this case, the control unit 7 estimates the average value of the absolute wind speed V _wind for 3 seconds calculated every 0.25 seconds based on the equation (8) as the instantaneous wind speed, and uses the average value of the instantaneous wind speed for 10 minutes as the wind speed. presume. The control unit 7 may estimate the absolute wind speed V _wind calculated every 3 seconds based on the equation (8) as the instantaneous wind speed in order to reduce the processing load. Further, preferably, the control unit 7 turns on the bicycle brake based on the output of the brake sensor 56 or the like in consideration of the fact that the resistance due to the wind and the resistance due to the brake cannot be distinguished during the braking of the bicycle. If it is determined that there is, it is preferable not to _perform the calculation process of the absolute wind speed V _wind . Further, when the absolute wind speeds of a plurality of traveling direction components are obtained at substantially the same position and time, the wind direction and the wind speed at that position may be estimated by using a vector method or the like.

(5) Ranking Table Display Process Next, a display example of the ranking table to be displayed on the terminal device 9 in the first embodiment and a process for generating ranking information Sr necessary for displaying the ranking table will be specifically described. Generally, the server device 8 calculates a first score based on the travel time of the target route Rtag and a second score based on the absolute wind speed in the target route Rtag, and totals these scores (“Traveling environment consideration”). The ranking of users in the ranking table is determined based on "score"). As a result, the server device 8 displays the ranking in consideration of the influence of the wind received by each user.

Here, the first score is set to a higher value as the movement time is shorter, and the second score is set to a higher value as the wind hinders the movement of the bicycle. The first score may be, for example, a relative value considering the travel time of all users in the target route Rtag (for example, a value based on a deviation value or a difference from the average value), and is based only on the target travel time. It may be an absolute value to be calculated. The second score is a score calculated based on the average of absolute wind speeds calculated at each point of the target route Rtag. For example, a tail wind has a positive value and a head wind has a negative value. Set. The formula or map for calculating the first score and the second score is stored in advance in the storage unit 13 or the like of the server device 8. The first score and the second score are examples of the "first index" and the "second index" in the present invention, respectively. The driving environment consideration score is an example of the "total value" in the present invention.

The ranking table shown in FIG. 7 shows "rank", "name", "date", "speed", "heart rate", "power", "average rising speed", "time", "air resistance", and "wind". Includes "Level", "Score", and "Lead out" items. In this case, the server device 8 extracts the travel information related to the target route Rtag specified in the request signal of the ranking information Sr from the user-specific travel information DB 80, and performs a predetermined calculation based on the extracted information. The value of the item is determined. Here, "F", one of the users who traveled on the target route Rtag, uses the terminal device 9 to display the ranking table. In this case, the server device 8 is the terminal device 9 based on login authentication or the like. The user recognizes that it is "F" and highlights the line corresponding to "F".

The "rank" indicates a rank for each user who has traveled on the target route Rtag. The server device 8 sets the above-mentioned ranking so that the higher the driving environment consideration score indicated by the “score” described later, the higher the ranking. The "name" indicates the identification information (user ID) of each user registered in the user-specific driving information DB 80 and the like, and the "date" is the target specified based on the time information registered in the user-specific driving information DB 80.

The average of the power Pp and the like is shown, and the "average climbing speed" indicates the average climbing speed (VAM) which is a direct index regarding the climbing speed while traveling on the target route Rtag. The server device 8 calculates the above-mentioned values such as heart rate for each user based on the driving information for each user extracted from the driving information DB 80 for each user.

The “time” indicates the travel time required for traveling on the target route Rtag. For example, the server device 8 indicates the time at the departure point of the target route Rtag registered in the user-specific travel information DB 80 and the time when the target route Rtag arrives. The above-mentioned travel time is calculated based on the time in. The travel time described above may be calculated by the cycle computer 1. In this case, the server device 8 receives the travel information St including the travel time of the target route Rtag calculated by the cycle computer 1 from the cycle computer 1.

“Air resistance” indicates the average of air resistance Pa calculated by the cycle computer 1 while traveling on the target route Rtag. In this way, by providing the item of "air resistance" and presenting it to the user, the user can change the form or equipment (for example, motorcycle or wear) in consideration of the front projection area A so that the air resistance is reduced. The necessity of the above can be preferably examined.

The "wind level" is an index based on the absolute wind speed (specifically, the average value of the absolute wind speed, etc.) calculated by the cycle computer 1 while traveling on the target route Rtag. In this example, the server device 8 has a wind level of "+2" when the absolute wind speed on the target route Rtag is 5 m or more, a wind level of "+1" when the head wind is 0 m to 5 m, and a tail wind of 0 m to 5 m. The wind level is set to "-1", and the wind level when the tail wind is 5 m or more is set to "-2". In this way, the server device 8 sets the wind level to a value so high that the wind hinders the movement of the bicycle. As a result, the wind level is set to a high value for the user who ran on the date and time when the head wind was strong and the user who ran by pulling the head of the group (that is, actively receiving air resistance).

In the "score", a driving environment consideration score of each user is set. The server device 8 sets the driving environment consideration score in the “score” as the total value of the first score calculated from the travel time indicated by the “time” and the second score calculated from the wind level indicated by the “wind level”. It is calculated as. In the example of FIG. 6, as an example, the server device 8 sets the first score as “50” when the travel time indicated by “time” is 1 hour 20 minutes 19 seconds, and is slower than 1 hour 20 minutes 19 seconds. The value obtained by subtracting the number from 50 is calculated as the first score of each user. Further, the server device 8 regards the wind level as the second score, and sets the total value of the first score and the second score as the “score”. As a result, the driving environment consideration score indicated by the "score" becomes higher as the travel time indicated by the "time" becomes shorter, and becomes higher as the wind level indicated by the "wind level" becomes higher.

In "Lead out", a lead-out index indicating the degree of contribution leading the group is set. Here, the server device 8 recognizes the time when the group was formed and the users who formed the group based on the time-series position information, time information, and the like of each user extracted from the user-specific travel information DB 80. Further, the server device 8 refers to each pedaling power Pp of the users forming the group, and recognizes the user having the highest pedaling power Pp as the first user in the group. Then, based on the above recognition result, the server device 8 aggregates the time (also referred to as “lead-out time”) at the head of the group for each user who has traveled on the target route Rtag, and the lead-out time is long. The higher the lead-out index is set. Here, as an example, the lead-out index is set in five stages from "-2" to "2".

Preferably, the server device 8 may set the lead-out index higher as the resistance of the wind received when it is located at the head of the group is larger. In this case, for example, the server device 8 determines the wind level corresponding to the average of the absolute wind speeds when it is located at the head of the group, and sets the lead-out index higher as the determined wind level is higher.

In this way, the server device 8 can preferably make the user of the terminal device 9 grasp the degree of contribution of each user who has led the group by providing the item corresponding to the lead-out index in the ranking table.

FIG. 8A shows a ranking table when the user of the terminal device 9 inputs an instruction for rearranging the ranking table based on the item “Lead out” to the terminal device 9.

In this case, the server device 8 that has received the predetermined request signal from the terminal device 9 has the ranking table shown in FIG. 7 so that the higher the lead-out index indicated by "Lead out", the higher the ranking indicated by "rank". It is updated, and the updated display information of the ranking table is transmitted to the terminal device 9. In this case, as shown in FIG. 8A, the terminal device 9 displays the ranking table so that the higher the lead-out index indicated by "Lead out", the higher the user. According to this aspect, the user of the terminal device 9 can grasp the ranking based on the degree of contribution that led the group.

FIG. 8B shows a ranking table when a user of the terminal device 9 inputs a display instruction of a ranking table that extracts only users having a predetermined wind level to the terminal device 9. In the example of FIG. 8B, as a result of the user of the terminal device 9 designating the wind level "+2", the terminal device 9 ranks four users whose wind level is "+2". The table is displayed. In this way, the user of the terminal device 9 can also specify an arbitrary wind level and display the ranking table on the terminal device 9.

As described above, the server device 8 according to the first embodiment stores the user-specific travel information DB 80 updated by the travel information St received from the cycle computer 1, and refers to the user-specific travel information DB 80. Information on the travel time for each user on the target route Rtag to which a plurality of users move and information on the absolute wind speed received by each user on the target route Rtag are acquired. Then, the server device 8 calculates the ranking of each user by calculating the driving environment consideration score based on the acquired travel time information and the absolute wind speed information, and displays the ranking table on the terminal device 9. To reflect. As a result, the server device 8 can present the user of the terminal device 9 with a ranking that suitably reflects the influence of the wind resistance.

<Second Example>
In the second embodiment, instead of calculating the traveling environment consideration score based on the absolute wind speed, the server device 8 assumes that the absolute wind speed is 0, and the travel time of each user of the target route Rtag (“absolute travel time”). ”) Is calculated, and the ranking of each user in the ranking table is determined based on the absolute travel time. Hereinafter, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

First, a method of calculating the speed of the bicycle (also referred to as “wind canceling speed”) assuming that the absolute wind speed is 0 will be described. The wind cancellation speed is used to calculate the absolute travel time.

Based on the equation (7), if it is assumed that the absolute wind speed V _wind is 0, "V _all = V" holds. Therefore, when this relationship is applied to the equation (6) relating to the air resistance Pa, the following equation is applied. (9) is obtained.

Further, the right side of the equation (5) obtained based on the equation (1) showing the relationship between the pedaling power Pp and the sum of the work rates of the drag applied to the bicycle and the right side of the above equation (9) are both air. Indicates resistance Pa. Therefore, if the right side of the equation (5) and the right side of the equation (9) are connected by an equation and the V is arranged, a cubic equation for V can be obtained as shown in the following equation (10).

The solution of equation (10) can be obtained algebraically, for example, based on Cardano's formula. In this case, there may be a maximum of three solutions, but V can be uniquely obtained by adding the condition V> 0. In addition, it is also possible to calculate the solution of the equation (10) by using a known calculation method such as an approximate solution method based on Newton's method or the like. Further, when the wind canceling speed is obtained, the absolute travel time can be calculated by dividing the distance of the target route Rtag by the wind canceling speed.

In consideration of the above, in the second embodiment, the cycle computer 1 calculates the wind canceling speed based on the equation (10) instead of the absolute wind speed V _wind , and includes the calculated wind canceling speed in the traveling information St to be a server. It transmits to the device 8. In this case, the server device 8 registers the wind cancellation speed at each point of the travel route included in the travel information St in the user-specific travel information DB 80. In this case, for example, the server device 8 calculates the average wind canceling speed for each user in the target route Rtag with reference to the user-specific traveling information DB 80 when the ranking information Sr is generated. Then, the server device 8 calculates the absolute travel time by extracting the distance of the target route Rtag from the map data 81 or the like and dividing by the average of the calculated wind cancellation speeds or the like.

FIG. 9 is an example of a ranking table displayed by the terminal device 9 in the second embodiment. In the ranking table shown in FIG. 9, the “rank”, “name”, “date”, “speed”, “heart rate”, “power”, “average rate of increase”, and “time” described in FIG. 7 and the like are shown. In addition, there is an item of "wind cancellation time" that indicates the absolute travel time. Then, in the example of FIG. 9, the user whose absolute movement time indicated by the "wind cancellation time" is shorter is arranged so that the rank indicated by the "rank" is higher. As described above, according to the second embodiment, the user of the terminal device 9 can grasp the ranking that preferably reflects the influence of the wind.

As described above, the server device 8 according to the second embodiment stores the user-specific travel information DB 80 updated by the travel information St received from the cycle computer 1, and refers to the user-specific travel information DB 80. The absolute travel time for each user in the target route Rtag to which a plurality of users travel is calculated. Then, the server device 8 calculates the ranking of each user based on the absolute travel time, and reflects it in the ranking table displayed on the terminal device 9. As a result, the server device 8 can suitably present the ranking that appropriately reflects the influence of the wind resistance to the user of the terminal device 9.

<Modification example>
Next, a modification suitable for each of the above-described examples will be described.

In this case, the traveling information St received from the cycle computer 1 contains information such as air resistance Pa, atmospheric density ρ, front projected area A, and velocity V required to calculate the absolute wind speed V _wind from the equation (8). The server device 8 calculates the absolute wind speed V _wind based on the pre-stored equation (8) and the received travel information St. Even in this case, the server device 8 can preferably calculate the driving environment consideration score for each user and determine the ranking of each user in the ranking table, as in the first embodiment.

Similarly, in the second embodiment, instead of the cycle computer 1 calculating the wind canceling speed based on the equation (10), the server device 8 may calculate the wind canceling speed based on the equation (10).

In this case, for example, the traveling information St received from the cycle computer 1 includes the gradient θ, the front projected area A, the atmospheric density ρ, the weight mb, the mc, etc. required to calculate the wind canceling speed from the equation (10). The information is included, and the server device 8 calculates the wind cancellation speed based on the equation (10) stored in advance and the received travel information St. Even in this case, the server device 8 can preferably calculate the absolute travel time for each user and determine the ranking of each user in the ranking table, as in the second embodiment.

(Modification 2)
In the first embodiment, the server device 8 may correct the traveling environment consideration score based on the weather information when each user travels on the target route Rtag.

For example, the server device 8 receives information on the weather (sunny, rain, etc.) and / and the temperature when traveling on each user's travel route from a server or the like that manages the weather information, and stores the information in the user-specific travel information DB 80. Then, the server device 8 extracts the weather information at the time of traveling of the target route Rtag stored in the user-specific traveling information DB 80 at the time of generating the ranking information Sr, and based on the extracted weather information, the first and second scores. The driving environment consideration score, which is the total value of, is corrected. In this case, the server device 8 considers the traveling environment when, for example, the weather during traveling on the target route Rtag is the weather (for example, rain, snow) or the air temperature (for example, the temperature below freezing point) that causes a poor traveling environment. Increase the score by a predetermined value or a predetermined rate. By doing so, the server device 8 can perform fair ranking that accurately reflects the traveling environment.
