Abstract

<P>PROBLEM TO BE SOLVED: To perform forced movement and health maintenance using an electric power assist bicycle. <P>SOLUTION: Two health maintenance modes of a normal mode and a forced movement mode are selected according to mode selection of a user. In the normal mode, consumed calorie, pulse, body fat at the time of traveling a bicycle are detected and indicated to an indicating part 41, so as to appropriately indicate an advice message. Also, in the forced movement mode, the bicycle is traveled by applying a load by controlling a regeneration brake and a gear change ratio. A reference pulse number is determined according to predetermined user information and a movement strength level, and increase and decrease of the load is controlled while detecting a number of pulse for maintaining an optimum forced movement condition. That is to say, the pulse number is increased by the forced movement. When it reaches to a reference pulse number, a load level is reduced to wait for deterioration of the pulse number. When the pulse number is reduced, the load level is controlled to increase again. <P>COPYRIGHT: (C)2005,JPO&NCIPI

[0018]
FIG. 4 is a block diagram showing the configuration for realizing the regenerative braking operation of the configuration shown in FIG. 2 in a little more detail.
As shown, a regenerative current calculation unit 54 for calculating a regenerative current amount is provided between the motor driver 52 and the motor controller 53.
The motor controller 53 outputs a current command value to the regenerative current calculation unit 54 based on an instruction from the vehicle controller 31. In an operation in a forced motion mode to be described later, a regeneration corresponding to the regeneration amount from the motor controller 53 is performed. The current command value is output to the regenerative current calculation section 54, and the regenerative current value corresponding to the command value is calculated by the regenerative current calculation section 54 and output to the motor driver 52.
The motor driver 52 controls the current between the motor 51 and the battery unit (battery) 14, supplies a drive current to the motor 51 during assist driving, and supplies a regenerative current from the motor 51 to the battery 14 during regeneration. The motor driver 52 controls the regenerative current in the direction opposite to the assist current when the bicycle is running, so that the regenerative braking by the motor 51 can be applied to apply a load.
In the present example, the operation in the forced exercise mode in which a high load is applied to the power running of the user is performed by the control of the regenerative brake and the control of the transmission gear ratio.
FIG. 5 shows a combination pattern of the regeneration amount [%] and the transmission gear ratio [1st to 4th speed]. As shown in the figure, in this example, a 16-step exercise amount is automatically selected to control the load applied to the power running of the user.
[0019]
FIG. 6 is a plan view showing a specific example of the display screen of the display unit 40 in this example, and shows a display state in an initial state during normal traveling.
As shown in the figure, the display screen includes a running mode display 71, a transmission gear level display 72, lighting displays 731, 732, 733, 74 of various lights, a speed display 75, a regeneration ratio display 76, an assist ratio display 77, and a regeneration display.

Further, the above-described left key 421, right key 422, enter key 423, and mode key 424 are provided at the lower side of the screen.
In this example, the operation state of the bicycle is set to a normal exercise mode (normal mode) or a forced exercise mode, which will be described later, by performing a health management mode selection operation on the display screen shown in FIG. It displays calories, pulse, body fat, and advice.
[0020]
Next, a method of calculating calorie consumption in this example will be described.
In this example, the calorie consumption is calculated based on the pedaling force from the pedal detected by the torque sensor 35 and the crank rotation angle detected from the crank FG36.
First, the vehicle controller 31 performs the following calculation using the pedaling force from the pedal detected by the torque sensor 35 and the crank rotation angle detected from the crank FG 36 as a repetitive operation per unit time.
Work amount [J] = pedal force [Nm] × crank rotation angle [rad]
Then, the work amount per unit time obtained by this calculation is continuously integrated during the calorie calculation mode to obtain the total work amount.
Then, this work amount is converted into a calorie value using the following conversion formula.
1 [cal] = 4.18605 [J]
The vehicle controller 31 transmits the information on the integrated calorie value to the display controller 43 by serial communication, and displays the information on the display unit 41.
With such a method, the calorie display can be performed by accurately calculating the work load.
[0021]
Next, the operation of the health management mode of the present example will be described.
The health management mode of the present embodiment is to select and execute two modes, a normal mode and a forced exercise mode, according to the mode selection of the user.
In the normal mode, the running of the bicycle is controlled normally, but the operation is such that the calorie consumption, the pulse, and the body fat during this running are detected and displayed on the display unit 41, and the advice message is appropriately displayed.
On the other hand, in the forced exercise mode, the vehicle travels with a load by controlling the regenerative braking and the transmission gear ratio described above.However, the reference pulse rate is determined based on preset user information and exercise intensity level, and the pulse rate is determined. It controls the increase and decrease of the load while detecting to maintain the optimal forced motion state. That is, when the pulse rate is increased by the forced exercise and reaches the reference pulse rate, the load level is decreased and the pulse rate is waited for to decrease, and when the pulse rate decreases, the load level is controlled to increase again. .
The user information includes age, gender, height, weight, and the like. The exercise intensity is arbitrarily selected by the user, and is selected from, for example, “strong”, “normal”, and “weak”. Once such information is set, it can be continuously used as valid data unless an update operation is performed.
[0022]
Hereinafter, the normal mode and the forced exercise mode will be specifically described.
1) Normal Mode First, when the normal mode is selected by the user, the display controller 43 acquires pulse and body fat data at the time of activation, and stores the data in the RAM 48 or the like.
During traveling, the vehicle controller 31 calculates calorie consumption from the pedal depression force and the pedal rotation angle, and transmits the calorie consumption to the display unit 40.
The display controller 43 periodically acquires pulse and body fat data, stores the data in the RAM 48, acquires the calorie consumption from the vehicle controller 31, and stores it in the RAM 48. Then, the data of the calorie consumption, the pulse, and the body fat, which are periodically acquired and stored in the RAM 48, are sent to the display unit 41 for display. FIG. 7 shows a display example in this case. Data 82, 83, and 84 of calorie consumption, pulse, and body fat are displayed in the display area of the traveling speed shown in FIG. In the running mode 71, “N” indicating the normal mode is displayed.
Then, for example, the display of the traveling speed shown in FIG. 6 and the display of the calorie consumption, the pulse, and the body fat shown in FIG. 7 are alternately switched and displayed in units of several seconds, so that both displays are displayed in a limited display area. It becomes possible. However, various forms of such a display can be adopted according to each design concept, and it is a matter of course that the present invention is not limited to the illustrated example.
At the end of traveling, the display controller 43 acquires final data on calorie consumption, pulse, and body fat, displays the data on the display unit 41, and displays a character string message on the display unit 41. For example, judging from information such as calorie consumption, a display such as “I'm tired”, “Let's exercise more!”, Or “Good luck!” Is selected and displayed on the display unit 41. In addition, as such a display form, not only a character string but also a graph display or other character display (for example, the expression of an animated character or the like changes) may be performed.
During traveling, an advice message may be displayed according to a change in the running speed or a change in the pulse. For example, when the speed suddenly changes or the pulse suddenly increases, a warning message is sent to suppress excessive exercise. Also, such a message may allow an option to be selected according to the user's preference. Further, by providing a voice synthesis output unit, it is possible to combine with a voice message.
[0023]
2) Forced Exercise Mode First, when the user selects the forced exercise mode, the user subsequently selects the intensity of the exercise from “strong”, “normal”, and “weak”. In addition, age, gender, weight, and height data are also input. If there is already registered data, it is possible to use that data without newly inputting it.
The forced exercise mode is activated by such an input, and the display controller 43 acquires pulse and body fat data and stores the data in the RAM 48 or the like.
Further, the display controller 43 calculates an optimal amount of exercise from the selected exercise intensity and the set user data, and determines an optimal pulse rate (reference pulse rate).
Next, during traveling, the display controller 43 acquires the pulse rate from the pulse meter 47, and if lower than the optimum pulse rate (reference pulse rate), raises the gear position of the transmission gear and increases the regenerative braking efficiency. And increase the load.
For example, the relationship between the pulse and the load calculated from the age, height, and weight of a person,
Weak: 140, Medium: 160, Strong: 180
Here, it is assumed that “strong” is selected by key operation.
Therefore, after the activation of the forced exercise mode, the display controller 43 acquires the data from the pulse meter, and if the data is smaller than 180, the pattern is changed from 16 to 1 by a combination of the tables shown in FIG.
Note that the gear position information and the regenerative efficiency information from the display controller 43 are sent to the vehicle controller 31 by communication, and the vehicle controller 31 controls the automatic transmission unit 34 based on the gear position received from the display controller 43 to switch gears. The regenerative efficiency received from the display controller 43 is sent to the motor controller 53 to change the regenerative braking amount.
[0024]
The display controller 43 periodically acquires pulse and body fat data and stores them in the RAM 48 or the like, and also acquires calorie consumption from the vehicle controller 31 and stores them in the RAM 48 or the like, and displays these on the display unit 41. At the same time, when the pulse rate reaches the reference pulse rate, the gear position of the transmission gear is reduced, the regenerative braking efficiency is reduced, and the load is reduced.
For example, in the above-described example, if the pulse rate is greater than 180, an instruction is issued to the vehicle controller 31 to reduce the amount of exercise, and if the pulse rate is less than 180, an instruction is issued to the vehicle controller 31 to increase the amount of exercise. .
Note that, as a display example, as shown in FIG. 8, basically the same as the normal mode can be used, but the difference is that “F” indicating the forced exercise mode is displayed in the traveling mode 71. Further, since the forced exercise is performed, the display 85 and 86 of the reference pulse rate and the exercise intensity, and the display 87 indicating the change of the load level may be performed.
Further, although omitted in the figure, a guidance message such as "let's slow down a little" or "do your best from here" may be sent according to the change of the pulse or the switching of the load level.
At the end of traveling, as in the case of the normal mode, the display controller 43 acquires the final calorie consumption, pulse, and body fat data and displays them on the display unit 41, and displays a character string message on the display unit 41. To be displayed. For example, judging from information such as calorie consumption, a display such as “I'm tired”, “Let's exercise more!”, Or “Good luck!” Is selected and displayed on the display unit 41. In the forced exercise mode, not only character strings but also graphs and other characters may be displayed. In particular, the switching state of the load level may be represented by a grab so that the period of the peak and the bottom can be easily grasped.
As in the case of the normal mode, a character may be used instead of a character string message, or a message to be used may be selected from a plurality of options in advance. Further, it can be combined with a voice message.
[0025]
Further, in the electric assist bicycle of this example, it is possible to perform an analysis by a personal computer using the pulse and body fat data acquired as described above.
Hereinafter, this PC analysis processing will be described.
After acquiring the data by the same processing as in the normal mode or the forced exercise mode described above, the data on the RAM 48 is downloaded to the memory stick 44. Then, the data on the memory stick 44 is read by the PC and saved on the PC. Then, software dedicated to data analysis is started on the PC to perform graph display, optimal value display, message display, weekly, monthly, and yearly data analysis, and display and manage tables and graphs.
[0026]
In the above example, the electric assist bicycle provided with both the normal mode and the forced exercise mode has been described, but a sufficient effect can be obtained even with a bicycle having one of the modes.
Further, the method of calculating the amount of exercise, the method of increasing / decreasing the load, and the method of displaying various numerical values are not limited to the above-described examples, and may be variously modified.
[0027]
【The invention's effect】

Has an effect that can be effectively contributed.
