[0002] It is known that people who are physically active or who exercise frequently have a lower incidence of death, ischemic heart disease, hypertension, diabetes, obesity, osteoporosis, colon cancer, and other diseases. It is also known that physical activity and exercise are effective in improving mental health and quality of life. Furthermore, it is known that physical activity in daily life, such as walking, is effective in reducing the probability of becoming bedridden and the mortality rate in elderly people. In Japan, the amount of physical activity has been decreasing due to the automation of housework and work and the development of transportation, which is one of the causes of the increase in lifestyle-related diseases in recent years. Therefore, the challenge is to provide methods and environments for many people to exercise in their daily lives without difficulty.

[Diagram 2] FIG. 1 is a graph showing the preventive effect of lifestyle-related diseases that can be expected by increasing the amount of physical activity (see Non-Patent Document 1). [Diagram 3] 1 is a flowchart illustrating the operation of a micromobility driving assistance system according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] [Embodiment Mode] <Configuration> FIG. 1 is a block diagram illustrating a micromobility driving assistance system according to an embodiment.

[0014] As shown in FIG. 1, a driving assistance system 10 for micromobility according to an embodiment includes a server 11, a mobile terminal 12, and micromobility 13.

[0015] The mobile terminal 12 acquires biometric information of a user who uses (drives) the micromobility 13, including the height, weight, age, and muscle mass. The user uses the mobile terminal 12 and the micromobility 13. The biometric information may include, for example, the user's heart rate. The mobile terminal 12 may, for example, capture (recognize) an overall image of the user's body using a camera that the mobile terminal 12 has, and calculate the user's height based on the captured overall image. The micromobility 13 may measure the user's weight when the user rides the micromobility 13. The micromobility 13 may measure the user's muscle mass when the user grips the handle of the micromobility 13. The micromobility 13 may measure the user's heart rate when the user grips the handle of the micromobility 13. The user's biometric information (physical information) may be registered in advance in the server 11 via the mobile terminal 12, or may be input and registered by the user in the mobile terminal 12. The mobile terminal 12 is, for example, a wearable terminal, a smartphone, a smart watch, or the like.

[0016] The mobile terminal 12 acquires an estimated amount of exercise that estimates the total amount of exercise in the user's daily life and the amount of exercise using the micromobility 13. The estimated amount of exercise is calculated based on activity amount data including calories burned when using the micromobility 13 and running time. For example, the total amount of exercise of the user's actual amount of exercise in daily life and the actual amount of exercise when using the micromobility up to a predetermined time in any one day may be acquired (measured), and the amount of exercise may be used as the estimated amount of exercise. The amount of exercise may be referred to as the amount of activity, the amount of exercise activity, or the amount of physical activity. Note that the part that calculates the estimated amount of exercise is not limited to the mobile terminal 12. Instead of the mobile terminal 12 calculating the estimated amount of exercise, the server 11 may calculate the estimated amount of exercise. In addition, the representative value of the amount of exercise in the user's daily life and the amount of exercise when using the micromobility 13 may be registered in advance in the server 11 via the mobile terminal 12 as the amount of exercise measured in advance. In addition, the user's micromobility 13 usage history, usage time, and travel route of the micromobility 13 may be registered in the server 11 via the mobile terminal 12 as activity information.

[0017] The server 11 calculates the amount of exercise required per day by the user based on the biometric information acquired by the mobile terminal 12. The server 11 may have a reference table that associates the biometric information with the amount of exercise required per day. For example, the server 11 increases the amount of exercise required as the user becomes taller, increases the amount of exercise required as the user becomes heavier, decreases the amount of exercise required as the user becomes older, and increases the amount of exercise required as the user becomes more muscular. The server 11 estimates the amount of exercise consumed by the micromobility 13 based on the estimated amount of exercise and the amount of exercise required. The server 11 calculates at least one of the load of the micromobility 13 and the travel route of the micromobility 13 so as to satisfy the amount of exercise consumed. A route home from a place other than the home, such as a company, to the home may be registered in advance in the server 11 as a travel route.

[0018] Figure 2 shows the preventive effect of lifestyle-related diseases that can be expected from increasing physical activity. As shown in FIG. 2, the relative risk of total mortality for those who consume less than 2000 kcal (kilocalories) per week (energy consumption for walking, stairs, and sports) compared to those who consume more than 2000 kcal per week is 1.31 (after adjusting for other risk factors). In other words, it can be understood that the risk of total mortality is reduced by aiming for a physical activity of 2000 kcal or more per week. In addition, the relative risk of developing coronary artery disease for those who consume less than 2000 kcal per week compared to those who consume more than 2000 kcal per week is 1.6 (after adjusting for other risk factors). In this way, people with low physical activity have a higher risk of total mortality and coronary artery disease compared to people with high physical activity. Therefore, for example, the amount of exercise required per day by the user may be calculated as 300 kcal, with a goal of a physical activity of 2000 kcal or more per week. In this way, the amount of exercise required per day by the user can be calculated by referring to a diagram such as that shown in FIG. 2.

[0019] For example, if a user's daily exercise volume is 180 kcal, the amount of exercise consumed will be 120 kcal, which is the difference between the required amount of exercise of 300 kcal and the required amount of exercise (required amount of exercise - amount of exercise in daily life = amount of exercise consumed when using micromobility).

[0020] The micromobility 13 sets a load on the pedals of the micromobility 13 so as to satisfy the amount of exercise consumed. For example, when the micromobility 13 is a bicycle, the load on the micromobility 13 refers to the load set on the pedals of the bicycle.

[0021] The micromobility 13 may be, for example, any one of a normal bicycle, a bicycle with a variable speed gear, an electric assist bicycle, and an electric assist bicycle with a variable speed gear. In general, the micromobility 13 may be a type of vehicle that moves by pedaling.

[0022] When the micromobility 13 is a normal bicycle, the server 11 calculates only the travel route. This is because when the micromobility 13 is a normal bicycle, the pedal load of the bicycle cannot be set to a desired value because there is no gear shift. When the micromobility 13 is a bicycle with gear shift or an electric assist bicycle, the server 11 calculates the load and the travel route. When the micromobility 13 is an electric assist bicycle or the like, the pedal load can be set to a desired value, so the server 11 calculates both the load and the travel route. When a slope is included in the travel route, the server 11 may calculate the travel route so as to satisfy the consumed exercise amount, taking into consideration that the pedal load is larger on the slope compared to a flat road. The server 11 may have a reference table for calculating the consumed exercise amount by associating the slope gradient (load) with the user's biological information.

[0023] If the user is subject to a heart rate restriction, the server 11 calculates a route of movement that keeps the heart rate at or below a predetermined heart rate and sets the load. A user subject to a heart rate restriction is, for example, a person who is trying to prevent the heart rate from exceeding a predetermined value due to a chronic heart disease or the like. In such a case, the server 11 lowers the pedal load so that the heart rate is at or below the predetermined heart rate, and guides the user to a longer, circuitous route. In such a case, the server 11 may calculate a route of movement that does not include a place where the pedal load is high (e.g., a slope, etc.). This makes it possible to ensure the required amount of exercise while keeping the heart rate at or below the predetermined heart rate.

[0024] The mobile terminal 12 displays the travel route calculated by the server 11 on the screen of the mobile terminal 12, and shows the travel route to the user. The user gets on the micromobility 13, heading for the destination of the travel route displayed on the mobile terminal 12 or his / her home.

[0025] <Effects> The driving assistance system according to the embodiment sets a load on the pedals of the micromobility to satisfy an amount of consumed exercise based on an estimated amount of exercise, which is the total amount of exercise in the user's daily life and the amount of exercise using the micromobility, and an amount of exercise required per day by the user. The user operates the micromobility with a load on the pedals until the user arrives at the destination. This allows the user to achieve the amount of exercise required for the day, thereby improving and maintaining the health of the user who uses the micromobility.

[0026] By aiming for a physical activity volume of, for example, 2,000 kcal or more per week, you can continuously manage your health, such as reducing total mortality rates and the risk of diabetes.

[0027] <Operation> FIG. 3 is a flowchart illustrating the operation of the micromobility driving assistance system according to the embodiment.

[0028] As shown in FIG. 3, the mobile terminal 12 acquires biometric information of the user, including the user's height, weight, age, and muscle mass (step S101).

[0029] The mobile terminal 12 acquires an estimated amount of exercise that is an estimate of the sum of the amount of exercise in the user's daily life and the amount of exercise using the micromobility 13 (step S102). The amount of exercise (calories burned) using the micromobility 13 is calculated, for example, by detecting the force (torque) exerted on the pedal of the micromobility 13 and based on the detected torque. The calories burned (amount of energy consumed) can be calculated by the formula (1). Calories burned (kcal) = METs × time (hours) × weight (kg) × 1.05 (1) The server 11 may accumulate data on the calorie consumption calculated by the formula (1) for each user.

[0030] Here, METs is a unit that indicates the intensity of physical activity, with a value of "1" being used when at rest (lying down or sitting comfortably). Regarding METs, the micromobility 13 may measure its own speed, select (convert) a corresponding value from a METs table (Non-Patent Document 2) based on the speed, and use the selected METs. The time may be measured by the micromobility 13 during its own travel and the measured travel time may be used. The weight of the user may be determined by measuring the weight of the user riding on the micromobility 13 and using the measured weight, or the weight from biometric information may be used.

[0031] The mobile terminal 12 may, for example, acquire the amount of exercise performed by the user in their daily life and the amount of exercise performed using micromobility 13 on a daily basis, accumulate and average the amount of exercise performed, and calculate (estimate) an estimated amount of exercise based on the averaged data.

[0032] 3, after step S102, the mobile terminal 12 transmits the bioinformation and the estimated amount of exercise to the server 11 (step S103). Note that the representative amounts of exercise in daily life and the amount of exercise using the micromobility 13 may be registered in advance in the server 11, and the server 11 may calculate the estimated amount of exercise based on the registered amounts of exercise.

[0033] The server 11 calculates the amount of exercise required per day for the user based on the biometric information (step S104). In principle, the server 11 calculates the amount of exercise required per day for the user based on the contents shown in FIG. 2 as, for example, 300 kcal. Furthermore, the server 11 adjusts the amount of exercise required according to the biometric information. A user whose height or weight is greater than the standard tends to need more exercise, and a user whose height or weight is smaller than the standard tends to need less exercise, and a user whose age is older tends to need less exercise because their metabolism is lower, a user whose age is younger tends to need more exercise because their metabolism is higher, a user whose muscle mass is larger tends to need more exercise because their metabolism is higher, and a user whose muscle mass is smaller tends to need less exercise because their metabolism is lower. The server 11 may take these matters into consideration when calculating the amount of exercise required per day for the user. For example, in the case of biometric information indicating that the amount of exercise required needs to be increased, the amount of exercise required may be 330 kcal, and in the case of biometric information indicating that the amount of exercise required needs to be decreased, the amount of exercise required may be 270 kcal.

[0034] The server 11 estimates the amount of exercise to be consumed through the micromobility 13 based on the estimated amount of exercise and the required amount of exercise (step S105). Specifically, the amount of exercise consumed is calculated (estimated) as shown in equation (2). Amount of exercise consumed = Amount of required exercise - Estimated amount of exercise (2) For example, if the required amount of exercise is 300 kcal and the estimated amount of exercise is 180 kcal, the amount of exercise consumed is estimated to be 120 kcal.

[0035] The server 11 calculates at least one of the load of the micromobility 13 and the travel route of the micromobility 13 so as to satisfy the consumed exercise amount (step S106). When there is another user having biometric information similar to the user's biometric information and the address of the other user is in the vicinity of the user's address (for example, within a 100-meter radius from the user's home), the server 11 may provide the pre-registered travel route of the other user as the user's travel route and set the load of the micromobility 13 when traveling the travel route so as to satisfy the consumed exercise amount of the user. When a slope or the like is present on the travel route, the server 11 may adjust the load to be set on the pedal of the micromobility 13 in consideration of the increased load on the slope. When the user wants to shorten the time it takes to arrive at the destination, the server 11 increases the load on the pedal and guides the user to a shortcut travel route to consume the consumed exercise amount (required calorie consumption). Furthermore, when the user wants to extend the time it takes to reach the destination, the server 11 reduces the pedal load and guides the user to a longer route to consume the consumed exercise energy. When the user is under too much stress, the server 11 may increase or decrease the daily consumed exercise energy from the average value in order to prevent the user from being overstressed for a predetermined period (e.g., three months). When the user is in poor health, the server 11 may decrease the daily consumed exercise energy from the average value.

[0036] After step S106, the micromobility 13 sets the load amount on the pedal of the micromobility 13 (step S107).

[0037] The mobile terminal 12 displays the travel route on the screen of the mobile terminal 12 (step S108). Furthermore, if the user does not hold the handle of the micromobility 13 within a predetermined time (e.g., 72 hours) from the last use of the micromobility 13, the mobile terminal 12 may display a message encouraging the use of the micromobility 13 on the screen of the mobile terminal 12. Furthermore, after using the micromobility 13, the mobile terminal 12 may display a message for encouraging use or the amount of physical activity when using the micromobility 13 on the screen of the mobile terminal 12.

[0038] <Features> The features of the driving assistance system according to the embodiment are as follows. Using micromobility (e.g., electric-assist bicycles), the system collects and accumulates the user's physical activity data and manages their health. Specifically, the system estimates the amount of exercise consumed through daily activities and the amount of exercise consumed using an electric-assist bicycle, and displays a route to travel and / or adjusts the load on the bicycle pedals to match the amount of exercise required per day. This helps the user maintain their health.

[0039] It should be noted that a part or all of the above processes may be executed by a computer program. The above-mentioned program may be stored using various types of non-transitory computer readable media and provided to a computer. The non-transitory computer readable medium includes various types of tangible storage media. Examples of the non-transitory computer readable medium include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program may also be provided to a computer by various types of transitory computer readable media. Examples of the transitory computer readable medium include electrical signals, optical signals, and electromagnetic waves. The transitory computer readable medium may provide the program to a computer via a wired communication path such as an electric wire and an optical fiber, or via a wireless communication path.

[0040] The invention has been specifically described above based on the embodiment, but it goes without saying that the present invention is not limited to the above embodiment and can be modified in various ways without departing from the spirit of the invention. [Explanation of symbols]
