[0004] However, in the electrically power-assisted bicycle of Patent Document 1, exercise intensity is set by inputting information into an age input area and an exercise intensity input area displayed on the controller display.

[0009] An electric power-assisted bicycle (hereinafter simply referred to as a "bicycle") 1 as a vehicle according to an embodiment of the present invention, and an input device 100 applied to the bicycle 1 will be described below with reference to the drawings.
[0010] First, the overall configuration of a bicycle 1 will be described with reference to FIGS.
[0011] Fig. 1 is a side view for explaining an overview of bicycle 1. Fig. 2 is a control block diagram of bicycle 1. Fig. 3 is a diagram showing a screen displayed on input device 100 while a rider is riding bicycle 1.
[0012] 1 and 2, the bicycle 1 includes a frame 2, a front wheel 3a, a rear wheel 3b as a driving wheel, a handlebar 4, a saddle 5, a driving sprocket 6a, a driven sprocket 6b, a chain 6c, a pair of pedals 7, a crank arm 7b as a pair of cranks, a crankshaft 7c, a support shaft 8, an electric assist unit 10, a vehicle speed sensor 14, a torque sensor 15, a cadence sensor 16 as an input speed sensor, a controller 20, a power storage unit 30, and an input device 100. In addition, the bicycle 1 may include, for example, a heart rate sensor 17 as a biosensor that can obtain information that is the basis for calculating the exercise load.
[0013] As shown in Fig. 1, bicycle 1 is ridden by a rider sitting astride saddle 5 and pedaling crank arm 7b via pedal 7. Bicycle 1 drives rear wheel 3b by pedal force (driving torque) transmitted from crank arm 7b to crankshaft 7c and driving force (assist torque) from electric assist unit 10 whose magnitude corresponds to the pedal force. In other words, bicycle 1 drives rear wheel 3b by power input by the rider and power input from motor 11 (see Fig. 2) of electric assist unit 10, which will be described later.
[0014] The frame 2 is a so-called diamond frame having a generally parallelogram shape in a side view. A front wheel 3a and a rear wheel 3b are rotatably attached to the frame 2. The frame 2 has a front fork 2a that supports the front wheel 3a.
[0015] The front wheel 3a is steered left and right by rotating the front fork 2a through the operation of a handlebar 4 by the rider.
[0016] The rear wheel 3b rotates about a support shaft 8. A driven sprocket 6b and an electric assist unit 10 are attached to the rear wheel 3b.
[0017] The driving torque is transmitted to the driven sprocket 6b via a chain 6c that is wound around the driving sprocket 6a to which the driving force from the crank arm 7b is input. Note that, instead of the chain 6c, other power transmission members that transmit the driving torque, such as a belt, may be used.
[0018] The pedal 7 is used by the driver to input driving torque, and is connected to a crankshaft 7c via a crank arm 7b.
[0019] The support shaft 8 is attached to the frame 2. The support shaft 8 is provided so as to be unrotatable relative to the frame 2.
[0020] 2, the electric assist unit 10 includes a motor 11 and a speed change mechanism 13. The electric assist unit 10 generates an assist torque that assists the pedaling force applied by the driver.
[0021] The motor 11 is controlled based on a command signal from the controller 20. The motor 11 is capable of generating a driving force that assists the power input by the driver, and a regenerative force that converts the rotational energy of the rear wheel 3b into electric energy.
[0022] The transmission mechanism 13 changes the speed of at least one of the power input from the rider and the power input from the motor 11, and outputs the changed speed to the rear wheel 3b. That is, the transmission mechanism 13 may change the speed of only the power input from the rider, may change the speed of only the power input from the motor 11, or may change the speed of both the power input from the rider and the motor 11. Alternatively, the transmission mechanism 13 may be omitted and the power input from the rider and the power input from the motor 11 may be directly transmitted to the rear wheel 3b. Note that the transmission mechanism 13 is a manual transmission mechanism that is changed based on the operation of the rider, but may also be an automatic transmission mechanism in which the controller 20 executes the shift control based on the electric signals from the torque sensor 15 and the cadence sensor 16.
[0023] The speed sensor 14 detects the speed of the bicycle 1. Specifically, the speed sensor 14 detects the rotation speed of the rear wheel 3b. The speed sensor 14 only needs to be able to detect the speed of the bicycle 1, and may instead detect the rotation speed of the front wheel 3a, for example.
[0024] The torque sensor 15 detects the torque of the power input by the rider. Specifically, the torque sensor 15 detects the torque input from the crank arm 7b that is rotationally driven by the rider via the pedal 7. Alternatively, the torque sensor 15 may detect the torque transmitted from the driving sprocket 6a to the driven sprocket 6b via the chain 6c.
[0025] The cadence sensor 16 detects the input speed of power input by the rider. Specifically, the cadence sensor 16 detects the rotational speed of the crank arm 7b or the crankshaft 7c that is rotationally driven by the rider via the pedal 7, i.e., the rotational speed of the driving sprocket 6a. Alternatively, the cadence sensor 16 may detect the rotational speed of the driven sprocket 6b that is rotationally driven from the driving sprocket 6a via the chain 6c.
[0026] The vehicle speed sensor 14, the torque sensor 15, and the cadence sensor 16 are provided as separate components from the electric assist unit 10. Alternatively, the vehicle speed sensor 14, the torque sensor 15, and the cadence sensor 16 may be provided within the electric assist unit 10.
[0027] The heart rate sensor 17 detects the heart rate of the driver. Specifically, the heart rate sensor 17 is attached to a part of the driver's body, such as the wrist, and detects the heart rate of the driver by irradiating light onto the skin and detecting the light reflected by blood vessels.
[0028] The controller 20 is composed of a microcomputer equipped with a CPU, RAM, ROM, an input / output interface, etc. The controller 20 may be composed of a plurality of microcomputers. The controller 20 performs various processes by the CPU reading and executing a program stored in the ROM. Specifically, the controller 20 controls the driving force or regenerative force of the motor 11 based on electrical signals corresponding to the magnitude of the pedaling force input from the torque sensor 15, the rotation speed of the crank arm 7b input from the cadence sensor 16, and the heart rate of the rider detected by the heart rate sensor 17. When the shift mechanism 13 is an automatic shift mechanism, the controller 20 controls the shift of the shift mechanism 13. When the shift mechanism 13 is not provided, the controller 20 controls the driving force or regenerative force of the motor 11 according to the power input from the rider. The controller 20 includes an inverter, a DC-DC converter, etc. for controlling the motor 11.
[0029] The power storage unit 30 is a chargeable and dischargeable secondary battery such as a nickel-metal hydride battery or a lithium-ion battery. The power storage unit 30 supplies power to the motor 11 via the controller 20 and is capable of charging regenerative power from the motor 11. The power storage unit 30 supplies power to the controller 20. The power storage unit 30 is provided so as to be detachable from the frame 2.
[0030] The input device 100 is operated by the rider. The input device 100 is for setting the exercise intensity of the rider. The input device 100 is composed of a microcomputer equipped with a CPU, RAM, ROM, an input / output interface, etc. The input device 100 can also be composed of multiple microcomputers. The input device 100 performs various processes by the CPU reading and executing a program stored in the ROM. The input device 100 is detachably provided on the handlebar 4 of the bicycle 1. The input device 100 is a smartphone that is connected to the controller 20 of the bicycle 1 by wire or wirelessly so as to be able to communicate with the controller 20. The input device 100 has a touch screen 101 that serves as both a display unit and an input unit, and a communication unit 102. Note that the input device 100 may not be a smartphone, but may be one that has equivalent functions and is fixed to the bicycle 1.
[0031] As shown in FIG. 2, the touch screen 101 has a driving mode setting screen 41, a physical parameter input section 42, and an exercise intensity setting screen 110.
[0032] The driving mode setting screen 41 is a screen for selecting a driving mode of the bicycle 1. The bicycle 1 has a standard mode used during normal riding, and a fat burning mode in which the exercise intensity is set higher than that of the standard mode. The rider can set either the standard mode or the fat burning mode by inputting information on the driving mode setting screen 41.
[0033] As shown in FIG. 3, when the rider is riding the bicycle 1 with the mode switched to fat burning mode, a status display section 103 and an exercise intensity graph 104 are displayed on the touch screen 101.
[0034] The status display unit 103 displays the current status of the driver. In this case, when the driver is performing aerobic exercise that burns fat, the status display unit 103 displays a message indicating that fat is being burned. This makes it possible to visually convey the current status of the driver. In addition, the status display unit 103 can display warming up, aerobic exercise, anaerobic exercise, maximum intensity, and the like.
[0035] The exercise intensity graph 104 displays the current driving intensity level of the driver in a graph form. This makes it possible to visually convey the exercise intensity of the driver. The exercise intensity level is calculated based on the oxygen intake calculated by the controller 20 from the magnitude of the pedaling force input from the torque sensor 15 and the rotation speed of the crank arm 7b input from the cadence sensor 16, or based on the driver's heart rate detected by the heart rate sensor 17.
[0036] The physical parameter input unit 42 is an input unit that allows input of the physical parameters of the driver. The physical parameters include the gender, weight, age, and exercise experience of the driver.
[0037] The exercise intensity setting screen 110 is a screen for setting the exercise intensity of the driver. The exercise intensity setting screen 110 will be described in detail later with reference to FIGS.
[0038] The communication unit 102 is a communication module capable of communicating with an external server (not shown) and performing data communication using a mobile phone communication network, a wireless LAN (Local Area Network), or the like.
[0039] Next, the exercise intensity setting screen 110 will be described with reference to FIG. 4 to FIG.
[0040] FIG. 4 is a diagram showing an example of the exercise intensity setting map 120 on the exercise intensity setting screen 110. FIG. 5 is a diagram showing the exercise intensity distribution area 122 when age is input on the exercise intensity setting screen 110 of FIG. 4. FIG. 6 is a diagram showing the exercise intensity distribution area 122 when gender is further input on the exercise intensity setting screen 110 of FIG. 5. FIG. 7 is a diagram showing a state in which the driver moves the pointer 121 within the exercise intensity setting map 120 on the exercise intensity setting screen 110 of FIG. 6. FIG. 8 is a diagram showing a state in which the older person exercise intensity distribution area 122a and the younger person exercise intensity distribution area 122b are displayed superimposed on the exercise intensity setting map 120. FIG. 9 is a diagram showing a state in which the position of the pointer 121 set by another user is displayed superimposed on the exercise intensity setting map 120. FIG. 10 is a diagram showing a state in which the relationship of the standard maximum oxygen intake amount to age and the relationship of the standard weight to age are displayed. FIG. 11 is a diagram showing another example of the exercise intensity setting map 120 on the exercise intensity setting screen 110.
[0041] As shown in Fig. 4, the exercise intensity setting screen 110 is a screen for setting the exercise intensity of the rider. The exercise intensity setting screen 110 is displayed when the bicycle 1 is set to the fat burning mode. As a result, the exercise intensity setting screen 110 is displayed when the rider intentionally selects the fat burning mode instead of the standard mode, so that the rider can set the exercise intensity according to his / her intention. The exercise intensity setting screen 110 displays the body parameter input section 42 and an exercise intensity setting map 120.
[0042] The physical parameter input section 42 has an age input section 42a and a gender input section 42b.
[0043] The age input section 42a is an input section for inputting the age of the driver. When the driver taps the age input section 42a, a number input pad (not shown) for inputting numbers is displayed on the exercise intensity setting screen 110. When the driver inputs his / her age from this number input pad, the age, which is one of the physical parameters, is input.
[0044] The gender input section 42b is an input section for inputting the gender of the driver. When the driver taps on the gender input section 42b, gender options are displayed on the exercise intensity setting screen 110 (not shown). When the driver selects his / her own gender from the gender options, the gender, which is one of the physical parameters, is input.
[0045] In the exercise intensity setting map 120, one of the vertical and horizontal axes is one of the physical parameters of the driver, and the other is one of the physical parameters of the driver. Here, an example will be described in which the vertical axis is physical strength set based on the maximum oxygen intake, which is one of the physical parameters of the driver, and the horizontal axis is body weight [kg], which is one of the physical parameters of the driver. The vertical axis is set so that the higher it goes, the closer it is to an "athlete" who has good physical strength, and the lower it goes, the closer it is to an "entry" who is a beginner. The horizontal axis is set so that the weight increases as it goes to the right and decreases as it goes to the left.
[0046] The physical fitness parameter may be set based on the driver's maximum oxygen intake or maximum heart rate, and may be any index that is correlated with the maximum oxygen intake. Examples of the physical fitness parameter include the driver's ankle brachial index (ABI), brachial-ankle pulse wave velocity (baPWV), accelerated plethysmography coefficient, high density lipoprotein (HDL), lower limb skeletal muscle mass, vital capacity, muscle strength test values, physical fitness test values, etc.
[0047] On the exercise intensity setting map 120, a pointer 121 and an exercise intensity distribution area 122 are displayed.
[0048] The pointer 121 indicates the weight and physical strength values set by default. In the default state, the pointer 121 is displayed at a position approximately in the center of the exercise intensity distribution area 122. The pointer 121 can be moved from the default position to another position by the rider's operation. As will be described in detail later, when the rider moves the pointer 121 to another position in the exercise intensity setting map 120, the exercise intensity of the bicycle 1 is set based on the weight and physical strength values at that position. When the pointer 121 is not moved from the default position in the exercise intensity setting map 120, the exercise intensity of the bicycle 1 is set based on the weight and physical strength values at the default position. That is, the exercise intensity of the bicycle 1 can be set based on the position where the pointer 121 is set in the exercise intensity setting map 120.
[0049] The exercise intensity distribution area 122 is set around the pointer 121 by default, and is an area set based on default information of the driver's physical parameters. The exercise intensity distribution area 122 is set based on the physical parameters of a group including the driver's age. Specifically, the exercise intensity distribution area 122 is set to an area where the driver can perform aerobic exercise to burn fat based on the driver's physical parameters. The exercise intensity distribution area 122 is an area set including all genders based on the relationship between the driver's age and average body weight, and the relationship between the driver's age and average maximum oxygen intake. In other words, the exercise intensity distribution area 122 is set as an area plotted by taking into account the distribution of the average body weight on the relationship between the driver's age and average maximum oxygen intake, regardless of the driver's gender. The exercise intensity distribution area 122 is set to the widest area in a default state where the driver's physical parameters are not input.
[0050] 5, when the driver inputs his / her age through the age input unit 42a, the exercise intensity distribution area 122 narrows. This is because the groups that include the driver's age are narrowed down, and groups that do not include the driver's age are excluded. In this way, the display of the exercise intensity distribution area 122 changes based on the input physical parameters.
[0051] In this example, the driver's age is input as "35 years old," so the exercise intensity distribution region 122 changes to a region of average exercise intensity based on the physical parameters of a group that includes the driver's age. Here, the group that includes the driver's age is set to, for example, a range of 35 to 39 years old in 5-year increments or a range of 30 to 39 years old in 10-year increments.
[0052] 6, when the driver selects his / her age from the gender input section 42b, the exercise intensity distribution area 122 narrows. This is because the groups that include the driver's gender are narrowed down, and groups that do not include the driver's gender are excluded. In this way, the display of the exercise intensity distribution area 122 changes based on the input physical parameters.
[0053] In this example, since "male" is selected as the gender of the driver, the exercise intensity distribution region 122 changes to a region of average exercise intensity based on the physical parameters of a group that includes the driver's age. Here, the group that includes the driver's age is set to "male" among all genders.
[0054] Furthermore, if the driver's age is input as "35 years old" and then the driver's gender is input as "male", the exercise intensity distribution region 122 changes to become even narrower. That is, the exercise intensity distribution region 122 changes to become narrower as the number of types of physical parameters input increases. Thus, the region is narrowed down to a group that includes the physical parameters input by the driver, and a group that does not include the physical parameters of the driver is excluded, thereby improving the accuracy of the region indicated by the exercise intensity distribution region 122.
[0055] As shown in FIG. 7, the driver can change the exercise intensity, which is set based on the default values of weight and physical strength, to an exercise intensity required by the driver by moving the pointer 121 from the state shown in FIG. 6.
[0056] Specifically, when the driver moves the pointer 121 in the direction of the physical strength "athlete," the exercise intensity changes to higher. On the other hand, when the driver moves the pointer 121 in the direction of the physical strength "entry," the exercise intensity changes to lower.
[0057] Also, when the driver moves the pointer 121 in the direction of a larger weight value, the exercise intensity is set to match the physical parameters of a person heavier than the driver, so the exercise intensity changes to higher. On the other hand, when the driver moves the pointer 121 in the direction of a smaller weight value, the exercise intensity is set to match the physical parameters of a person lighter than the driver, so the exercise intensity changes to lower.
[0058] In the example shown in FIG. 7, the driver moves the pointer 121 significantly from the default position toward the physical strength "athlete," so the exercise intensity changes to be significantly higher.
[0059] The controller 20 sets the assist ratio, which is the ratio between the power [W] input to the crankshaft 7c and the power [W] output by the motor 11, based on the exercise intensity input from the input device 100. Specifically, when the exercise intensity is reduced, the controller 20 increases the proportion of the torque generated by the motor 11. On the other hand, when the exercise intensity is increased, the controller 20 decreases the proportion of the torque generated by the motor 11. The assist ratio may be set based on the ratio between the power [W] input by the driver and the power [W] generated by the motor 11 among the torques transmitted to the rear wheel 3b. In this case, since it is the ratio of powers on the same axis and the rotation speeds are the same, it is also possible to use the ratio of each torque as the assist ratio.
[0060] When increasing the proportion of the torque generated by the motor 11, the controller 20 transmits an electric signal to the motor 11 to output a larger torque. On the other hand, when decreasing the proportion of the torque generated by the motor 11, the controller 20 transmits an electric signal to the motor 11 to output a smaller torque. Furthermore, when the torque generated by the motor 11 is insufficient even when it is set to 0, the controller 20 controls the motor 11 to regenerate so as to generate a resistance force in the opposite direction to the torque input by the driver. Therefore, by controlling the driving force or regenerative force of the motor 11, the motor 11 can be controlled to approach the exercise intensity required by the driver over a wide range.
[0061] As described above, the exercise intensity setting screen 110 of the input device 100 displays an exercise intensity setting map 120 in which one of the vertical and horizontal axes is one of the rider's physical parameters and the other is one of the rider's physical parameters. The rider can set the exercise intensity of the bicycle 1 simply by setting the position of the pointer 121 indicating the values of the physical parameter and the physical parameter with reference to the exercise intensity distribution area 122 set based on the default information of the physical parameter displayed on the exercise intensity setting map 120. Therefore, the exercise intensity can be set by an intuitive operation, and the burden on the rider in setting the exercise intensity can be reduced.
[0062] In addition, because the bicycle 1 is provided with a speed change mechanism 13, the driving force and regenerative force of the motor 11 can be increased based on the speed change ratio. This allows control to be performed so as to approach the exercise intensity required by the rider over a wider range.
[0063] As shown in FIG. 8, in the exercise intensity setting map 120, an older person exercise intensity distribution region 122a and a younger person exercise intensity distribution region 122b are displayed superimposed on the exercise intensity distribution region 122.
[0064] The older person exercise intensity distribution region 122a is set based on default information of physical parameters of a group older than the driver, and the younger person exercise intensity distribution region 122b is set based on default information of physical parameters of a group younger than the driver.
[0065] In this example, the driver's age is entered as "35 years old," so the group that includes the driver's age is set to a range of 30 to 39 years old in increments of 10 years. In contrast, the older exercise intensity distribution region 122a is set to a group of +10 years old, that is, a range of 40 to 49 years old. Moreover, the younger exercise intensity distribution region 122b is set to a group of -10 years old, that is, a range of 20 to 29 years old.
[0066] By displaying the older person exercise intensity distribution area 122a and the younger person exercise intensity distribution area 122b, if the driver feels that his / her subjective age is higher than his / her actual age, he / she can set the exercise intensity within the older person exercise intensity distribution area 122a of the one year older group, and if the driver feels that his / her subjective age is lower than his / her actual age, he / she can set the exercise intensity within the younger person exercise intensity distribution area 122b of the one year younger group.
[0067] Similarly to the exercise intensity distribution region 122, the older person exercise intensity distribution region 122a and the younger person exercise intensity distribution region 122b also change in accordance with the physical parameters input by the driver, becoming narrower as the number of types of physical parameters input increases.
[0068] As shown in FIG. 9, the position of a pointer 121 set by another user can be acquired from a server and displayed superimposed on the exercise intensity setting map 120.
[0069] This allows the driver to refer to the exercise intensity set by members of a particular team, for example, and can set the exercise intensity to the same as that set by other members, or to a higher exercise intensity than that set by the other members.
[0070] In addition, members belonging to a particular team are also displayed so that they can be easily identified by using different symbols (here, two types, "+" and "-") or different colors for each age group that the member belongs to.
[0071] 10, the relationship of standard maximum oxygen intake to age can be displayed separately for men and women on the touch screen 101 of the input device 100, and the relationship between the driver's age and maximum oxygen intake can be plotted. This allows the driver to compare his or her own maximum oxygen intake value with the standard value.
[0072] Furthermore, the touch screen 101 of the input device 100 can display the relationship between standard weight and age for both men and women, and plot the relationship between the driver's age and weight, allowing the driver to compare his or her own weight value with the standard value.
[0073] 10, the birth date of the driver may be input from the age input unit 42a. This allows the age of the driver at that time to be calculated from the date data held by the input device 100. Therefore, even if some time has passed since the last time the driver input his / her age, the driver does not need to re-input his / her age.
[0074] As shown in Fig. 11, the horizontal axis may represent the age, which is one of the physical parameters of the driver. In this case, the same effects as when the horizontal axis represents the weight can be obtained.
[0075] Next, with reference to Fig. 12 and Fig. 13, a calculation of exercise intensity using the torque sensor 15 and the cadence sensor 16 will be described as an example of calculation of exercise intensity. According to this example, the driver's heart rate is not used, so that the driver can be relieved of the inconvenience of wearing a heart rate detection sensor or the like. Here, a case where the calculation of exercise intensity is performed by the controller 20 will be described as an example. This is not limiting, and for example, some of the controls may be performed by the input device 100 and other controls may be performed by the controller 20. The calculation of exercise intensity is performed by the controller 20 at regular time intervals.
[0076] Fig. 12 is a diagram for explaining the relationship between the rotation speed of the crank arm 7b and the oxygen intake (X) of the rider. Fig. 13 is a diagram for explaining the relationship between the input torque and the oxygen intake (Y) of the rider.
[0077] The controller 20 calculates an oxygen intake amount (X) as a first oxygen intake amount of the rider based on the rotation speed of the crank arm 7b detected by the cadence sensor 16.
[0078] 12, the relationship between the rotation speed (S) of the crank arm 7b and the oxygen intake (X) of the rider is expressed by the following formula (1), where A, B, and C are constants that are set based on the physical parameters of the rider, the riding environment of the bicycle 1, etc. X=A+B×S C (1)
[0079] Therefore, the oxygen intake amount (X) of the rider can be estimated from the rotation speed of the crank arm 7b detected by the cadence sensor 16 based on equation (1).
[0080] The controller 20 calculates an oxygen intake amount (Y) as a second oxygen intake amount of the rider based on the torque input from the crank arm 7b detected by the torque sensor 15.
[0081] As shown in Fig. 13, the relationship between the input torque (T) and the oxygen intake (Y) of the rider is expressed by the following formula (2), where P and Q are constants that are set based on the physical parameters of the rider, the riding environment of the bicycle 1, etc. Y = P + Q × T (2)
[0082] Therefore, the oxygen intake amount (Y) of the rider can be estimated based on the torque input from the crank arm 7b detected by the torque sensor 15, based on equation (2).
[0083] The controller 20 calculates the driver's oxygen intake at rest (U) based on the driver's physical parameters. Specifically, the controller 20 calculates the driver's oxygen intake at rest (U), which is the driver's oxygen intake at rest, based on values statistically determined from the driver's physical parameters such as gender, weight, age, exercise experience, and physical strength.
[0084] The controller 20 calculates the total oxygen intake (Z) of the rider. Specifically, the controller 20 calculates the total oxygen intake (Z) of the rider in an exercise state based on the oxygen intake (X) estimated from the rotation speed of the crank arm 7b detected by the cadence sensor 16, the oxygen intake (Y) estimated from the torque detected by the torque sensor 15, and the rider's resting oxygen intake (U) at rest obtained from the body parameters, according to the following formula (3): Z=U+X+Y (3)
[0085] In this way, by estimating the oxygen intake (X) from the rotation speed detected by the cadence sensor 16 and the oxygen intake (Y) from the torque detected by the torque sensor 15, it is possible to improve the accuracy of estimating the total oxygen intake (Z) based on the internal and external workloads of the rider.
[0086] In addition, the controller 20 calculates the maximum oxygen intake (V) of the driver. Specifically, the controller 20 calculates the maximum oxygen intake (V) of the driver based on values statistically obtained from physical parameters such as the driver's sex, weight, age, exercise experience, and physical strength.
[0087] Then, the controller 20 calculates the exercise intensity (W) [%] of the driver. Specifically, the controller 20 can calculate the exercise intensity (W) in the driver's exercise state based on the driver's oxygen intake at rest (U) when at rest obtained from the physical parameters, the driver's total oxygen intake (Z) in the driver's exercise state, and the driver's maximum oxygen intake (V) according to the following formula (4). W [%] = (ZU) / (VU) × 100 (4)
[0088] By executing the above calculation process, the exercise intensity of the driver can be calculated. Alternatively, the exercise intensity of the driver may be calculated based on the heart rate of the driver detected by the heart rate sensor 17. When based on the heart rate of the driver, the exercise intensity of the driver can be calculated from the resting heart rate of the driver when at rest and the maximum heart rate of the driver.
[0089] In addition, when the exercise intensity (W) is set by the driver, the total oxygen intake (Z) is calculated based on equation (4), and the oxygen intake (Y) is calculated based on equation (3), thereby controlling the driving force or regenerative force of motor 11 so as to approach the exercise intensity required by the driver.
[0090] The configuration and effects of the present embodiment will now be described.
[0091] (1)(9) In a bicycle 1 in which a rear wheel 3b is driven by power input by the rider and power input from a motor 11, an input device 100 for setting the exercise intensity of the rider displays an exercise intensity setting map 120 in which one of the vertical and horizontal axes is one of the rider's physical parameters and the other is one of the rider's physical parameters, and has an exercise intensity setting screen 110 for setting the exercise intensity, and the exercise intensity setting map 120 displays a pointer 121 indicating the values of the physical parameter and the physical parameter set by default, and an exercise intensity distribution area 122 that is set by default around the pointer 121 and based on default information for the physical parameter, and the exercise intensity of the bicycle 1 can be set based on the position where the pointer 121 is set within the exercise intensity setting map 120.
[0092] According to this configuration, an exercise intensity setting map 120 is displayed on the exercise intensity setting screen 110 of the input device 100, in which one of the vertical and horizontal axes is one of the rider's physical parameters and the other is one of the rider's physical parameters. The rider can set the exercise intensity of the bicycle 1 simply by setting the position of a pointer 121 indicating the values of the physical parameter and the physical parameter with reference to an exercise intensity distribution area 122 set based on the default information of the physical parameter displayed on the exercise intensity setting map 120. Therefore, the exercise intensity can be set by an intuitive operation, and the burden on the rider in setting the exercise intensity can be reduced.
[0093] (2) The input device 100 has a physical parameter input unit 42 for inputting the physical parameters of the driver, and the display of the exercise intensity distribution area 122 changes based on the input physical parameters.
[0094] (3) The physical parameters include the driver's gender, weight, age, and exercise experience. The more types of physical parameters that are input, the narrower the exercise intensity distribution region 122 becomes.
[0095] According to these configurations, the population is narrowed down to one that includes the physical parameters input by the driver, and populations that do not include the physical parameters of the driver are excluded, thereby improving the accuracy of the area indicated by the exercise intensity distribution area 122.
[0096] (4) The input device 100 further has a driving mode setting screen 41 for selecting a standard mode used during normal driving and a fat burning mode in which the exercise intensity is set higher than that in the standard mode, and the exercise intensity setting screen 110 is displayed when the fat burning mode is set.
[0097] According to this configuration, the exercise intensity setting screen 110 is displayed when the driver intentionally selects the fat burning mode instead of the standard mode, so that the exercise intensity can be set according to the driver's intention.
[0098] (5) The vertical axis of the exercise intensity setting map 120 represents the physical strength of the driver based on the maximum oxygen intake (V), and the horizontal axis represents the weight of the driver.
[0099] According to this configuration, the vertical axis represents the physical strength of the driver and the horizontal axis represents the weight of the driver, so that the driver can intuitively set the exercise intensity in comparison with his / her own weight and physical strength.
[0100] (6) The exercise intensity distribution region 122 is set based on the physical parameters of a group that includes the driver's age, and the exercise intensity setting map 120 displays an older exercise intensity distribution region 122a set based on default information of the physical parameters of a group older than the driver, and a younger exercise intensity distribution region 122b set based on default information of the physical parameters of a group younger than the driver, superimposed on the exercise intensity distribution region 122.
[0101] According to this configuration, by displaying the older person exercise intensity distribution area 122a and the younger person exercise intensity distribution area 122b, if the driver feels that his / her subjective age is higher than his / her actual age, he / she can set the exercise intensity within the older person exercise intensity distribution area 122a of the one year older group, and if the driver feels that his / her subjective age is lower than his / her actual age, he / she can set the exercise intensity within the younger person exercise intensity distribution area 122b of the one year younger group.
[0102] (7) The input device 100 includes a communication unit 102 capable of communicating with an external server, and is capable of acquiring the position of a pointer 121 set by another user from the server and displaying it on the exercise intensity setting map 120 in an overlapping manner.
[0103] With this configuration, the driver can refer to the exercise intensity set by a member belonging to a particular team, for example, and can set the exercise intensity to the same as that set by other members, or to a higher exercise intensity than that set by other members.
[0104] (8) The input device 100 is a smartphone that is connected to the bicycle 1 via a wired or wireless connection.
[0105] According to this configuration, physical parameters and exercise intensity can be input from the input device 100. For example, the physical parameters and exercise intensity can be input in advance into the input device 100, and then the exercise intensity can be controlled by attaching the input device to the bicycle 1.
[0106] Although an embodiment of the present invention has been described above, the above embodiment merely illustrates one application example of the present invention, and is not intended to limit the technical scope of the present invention to the specific configuration of the above embodiment.
[0107] For example, in the above embodiment, the vehicle is described as a bicycle 1, but the vehicle may be another vehicle that assists the driver's power with the power of a motor, such as an electrically assisted kickboard or an electrically assisted wheelchair. When the vehicle is an electrically assisted kickboard, the power input by the driver kicking the ground with one foot is assisted by controlling the motor. When the vehicle is an electrically assisted wheelchair, the power input by the driver turning the wheels with their arms is assisted by controlling the motor.
[0108] In the above embodiment, the electric assist unit 10 is attached to the rear wheel 3b. Alternatively, the electric assist unit 10 may be attached to the front wheel 3a, and the front wheel 3a may be used as the drive wheel.
[0109] Furthermore, the controller 20 or the input device 100 may be connected to a cloud server (not shown) on the Internet, and the cloud server may act as an execution entity for some of the above-mentioned processes executed by the controller 20 and the input device 100.
[0110] That is, in the above embodiment, the case was described where the controller 20 and input device 100 mounted on the bicycle 1 are the entities that execute the control for setting the exercise intensity on the bicycle 1, but any one or a combination of the controller 20, the input device 100, and the cloud server corresponds to the controller.
[0111] The above-described series of processes in bicycle 1 may be provided as a program for a computer to execute the processes. The program for executing the above-described series of processes may be provided on a computer-readable storage medium. The various programs executed by the computer may be stored on a non-transitory storage medium such as a CD-ROM. [Explanation of symbols]
