[0048] The control unit 101 starts driving the motor 81a when the manual driving force becomes equal to or greater than the first threshold T1. When the control unit 101 starts driving the motor 81a, the control unit 101 controls the motor 81a so that the motor output increases proportionally as the manual driving force increases. When the manual driving force becomes equal to or greater than the second threshold T2, the control unit 101 controls the motor 81a so that the motor output maintains the maximum output value PM of the motor 81a.

[0049] The maximum output value PM of the motor 81a defines the upper limit of the output of the motor 81a when the control unit 101 controls the motor 81a. The maximum output value PM of the motor 81a may differ from the maximum output value based on the performance of the motor 81a. The second threshold value T2 is greater than the first threshold value T1. For example, the control unit 101 controls the motor 81a so that the ratio of the motor output to the human-powered driving force does not exceed a predetermined ratio. The relationship between the human-powered driving force and the motor output is defined according to the relationship between the running speed of the human-powered vehicle 1 and the Road Traffic Act, etc.

[0051] The control unit 101 is configured to be able to set the maximum output value PM of the motor 81a to a first output value PM1 or a second output value PM2. When the maximum output value PM of the motor 81a is set to the first output value PM1, the control unit 101 controls the motor 81a so that the motor output maintains the first output value PM1 when the manual driving force becomes equal to or greater than a second threshold value T2. When the maximum output value PM of the motor 81a is set to the second output value PM2, the control unit 101 controls the motor 81a so that the motor output maintains the second output value PM2 when the manual driving force becomes equal to or greater than a third threshold value T3. The third threshold value T3 is greater than the second threshold value T2.

[0052] The pressure detection unit 110 shown in FIG. 1 and FIG. 2 detects the position of the luggage placed on the loading platform C based on the pressure applied to the loading platform C. In addition to the position of the luggage placed on the loading platform C, the pressure detection unit 110 may further detect at least one of the weight, the position of the center of gravity, and the vibration of the luggage placed on the loading platform C. The pressure detection unit 110 is provided on the loading platform C.

The position of the luggage detected by the pressure detection unit 110 includes at least one of the position of the luggage placed on the main body C11 and the position of the luggage placed on the rear carrier C20. In this embodiment, the position of the luggage detected by the pressure detection unit 110 includes the position of the luggage placed on the main body C11.

[0053] The pressure detection unit 110 is formed, for example, in a sheet shape. The pressure detection unit 110 is placed on a loading surface C11a of the main body C11 on which luggage is loaded. The pressure detection unit 110 is provided to cover the entire loading surface C11a. The luggage loaded on the main body C11 is placed on the pressure detection unit 110. The pressure detection unit 110 detects the position of the luggage placed on the main body C11 based on the pressure from the luggage placed on the pressure detection unit 110.

[0054] The control unit 101 can obtain the position of the luggage placed on the loading platform C based on the detection signal output from the pressure detection unit 110. The control unit 101 controls the electric component 80 according to the position of the luggage placed on the loading platform C. In this embodiment, the control unit 101 controls the drive unit 81.

[0055] When it is detected that the luggage is placed at the first position, the control unit 101 sets the maximum output value PM of the motor 81a to the first output value PM1. The first position is a predetermined position on the loading platform C. In this embodiment, the first position is a position on the loading surface C11a of the main body C11 where the luggage is likely to fall. The first position is set based on experiments or the like conducted in advance. The memory unit 102 stores the first position. The first position includes position information such as, for example, the edge of the loading platform C and near a low point of the fence C11b of the loading platform C. In this embodiment, the position information of the edge of the loading platform C includes a predetermined area including the outer edge of the loading surface C11a.

[0056] The position information of the low point of the fence C11b of the loading platform C includes an area adjacent to the relatively low fence C11b of the loading surface C11a. The relatively low fence C11b includes, for example, the fence C11b whose height is less than a predetermined threshold value. When the heights of the fences C11b are different from each other, the relatively low fence C11b may be determined by comparing the heights of the fences C11b. For example, the fence C11b with a relatively low height may be determined as the relatively low fence C11b.

[0057] When the control unit 101 detects that the luggage is placed at a second position different from the first position, the control unit 101 sets the maximum output value PM of the motor 81a to a second output value PM2 that is greater than the first output value PM1. The second position is a predetermined position on the loading platform C. In this embodiment, the second position is a position on the loading surface C11a where the luggage is unlikely to fall. The second position does not overlap with the first position. The second position is set based on experiments or the like conducted in advance. The memory unit 102 stores the second position. The second position includes, for example, position information of the center part of the loading platform C and a part surrounded by a high fence C11b. In this embodiment, the position information of the center part of the loading platform C includes a predetermined area including the center position of the loading surface C11a.

[0058] The position information of the portion surrounded by the tall fences C11b includes an area of ​​the loading surface C11a adjacent to a plurality of relatively tall fences C11b. The relatively tall fences C11b include, for example, fences C11b whose height is equal to or greater than a predetermined threshold value. When the heights of the fences C11b are different from each other, the relatively tall fences C11b may be determined by comparing the heights of the fences C11b. For example, a relatively short fence C11b may be determined as the relatively tall fence C11b.

[0059] An example of control executed by the control unit 101 will be described. FIG. 5 is used to describe an example of control executed by the control unit 101. The control unit 101 starts a first control flow according to the flowchart shown in FIG. 5 when a predetermined condition is satisfied. In this embodiment, the control unit 101 starts the first control flow when power supply from the battery 60 to the control unit 101 is started and when a predetermined operation is performed on the operation device 43. When the first control flow ends, the control unit 101 repeatedly executes the first control flow at predetermined time intervals until a predetermined condition is satisfied. In this embodiment, the control unit 101 repeatedly executes the first control flow at predetermined time intervals until a predetermined operation is performed on the operation device 43.

[0060] In step S1, the control unit 101 acquires the position of the luggage placed on the loading platform C based on the detection signal output from the pressure detection unit 110. The control unit 101 acquires the first position by reading information stored in the memory unit 102. The control unit 101 detects that the luggage is placed at the first position by comparing the position of the luggage placed on the loading platform C with the first position. For example, the control unit 101 detects that the luggage is placed at the first position when at least a part of the position of the luggage placed on the loading platform C overlaps with the first position. When the control unit 101 detects that the luggage is placed at the first position, it proceeds to step S2. When the control unit 101 does not detect that the luggage is placed at the first position, it proceeds to step S3.

[0061] In step S2, the control unit 101 sets the maximum output value PM of the motor 81a to the first output value PM1. After performing the process of step S2, the control unit 101 ends the first control flow.

[0062] In step S3, the control unit 101 acquires the second position by reading information stored in the memory unit 102, and detects that the luggage is placed at the second position by comparing the position of the luggage placed on the loading platform C with the second position. For example, the control unit 101 detects that the luggage is placed at the second position when at least a portion of the position of the luggage placed on the loading platform C overlaps with the second position. When the control unit 101 detects that the luggage is placed at the second position, it proceeds to step S4. When the control unit 101 does not detect that the luggage is placed at the second position, it ends the first control flow.

[0063] In step S4, the control unit 101 sets the maximum output value PM of the motor 81a to the second output value PM2. After performing the process of step S4, the control unit 101 ends the first control flow.

[0064] The control unit 101 executes the first control flow to set the maximum output value PM of the motor 81a, thereby appropriately controlling the electric component 80 in accordance with the position of the luggage placed on the loading platform C. In this embodiment, the control unit 101 can appropriately control the drive unit 81 in accordance with the position of the luggage placed on the loading platform C.

[0065] In this embodiment, when a load is placed in the first position, the control unit 101 sets the maximum output value PM of the motor 81a to a first output value PM1 that is smaller than the second output value PM2, and reduces the assisting force of the human-powered vehicle 1. By reducing the assisting force of the human-powered vehicle 1, the control unit 101 can suppress an increase in the traveling speed of the human-powered vehicle 1 when the load is in a position where it is likely to fall, such as the edge of the loading platform C. By suppressing an increase in the traveling speed of the human-powered vehicle 1, the load is less likely to lose balance while the human-powered vehicle 1 is traveling, and it is possible to suppress the load placed on the loading platform C from falling while the human-powered vehicle 1 is traveling.

[0066] In this embodiment, when the luggage is placed at the second position, the control unit 101 sets the maximum output value PM of the motor 81a to a second output value PM2 that is greater than the first output value PM1. By setting the maximum output value PM of the motor 81a to the second output value PM2 that is greater than the first output value PM1, the control unit 101 increases the assist force of the human-powered vehicle 1 when the luggage is placed at a position where it is difficult to fall, such as the center part of the loading platform C, to realize a comfortable ride. In this embodiment, after detecting whether the luggage placed at the loading platform C is placed at a first position where it is easy to fall, if the luggage is not placed at the first position, it is detected whether the luggage is placed at a second position where it is difficult to fall, but the present invention is not limited to this embodiment. After detecting whether the luggage placed at the loading platform C is placed at a first position where it is difficult to fall, if the luggage is not placed at the first position, it may be detected whether the luggage is placed at a second position where it is easy to fall. After detecting whether the luggage is located at a first position where it is less likely to fall, if the luggage is not located at the first position, the first output value PM1 is set to a value greater than the second output value PM2 when detecting whether the luggage is located at a second position where it is more likely to fall.

When performing the first notification operation, the sound generating device 91 generates sound indicating that the luggage placed on the loading platform C is in a position where it is likely to fall.

[0071] The second notification operation is an operation different from the first notification operation. The second notification operation includes an operation of notifying that the luggage placed on the loading platform C is in a second position. In this embodiment, the second notification operation includes an operation of notifying that the luggage placed on the loading platform C is in a position where it is difficult to fall. When performing the second notification operation, the electronic terminal 87 performs at least one of displaying a message indicating that the luggage placed on the loading platform C is in a position where it is difficult to fall, generating vibrations, outputting light, and outputting sound, for example. When performing the second notification operation, the display 88 displays a message indicating that the luggage placed on the loading platform C is in a position where it is difficult to fall, for example.

When performing the second notification operation, the light generating device 90 generates light indicating that the luggage placed on the loading platform C is in a position where it is difficult to fall, for example. When the sound generating device 91 performs the second notification action, for example, it generates a sound indicating that the baggage placed on the loading platform C is in a position where it is unlikely to fall.

[0072] The control unit 101 causes the notification device to perform a notification operation according to the position of the luggage placed on the loading platform C. In this embodiment, when the control unit 101 detects that the luggage is placed at a first position, the control unit 101 causes the notification device to perform a first notification operation. When the control unit 101 detects that the luggage is placed at a second position, the control unit 101 causes the notification device to perform a second notification operation different from the first notification operation.

[0073] An example of control executed by the control unit 101 will be described. FIG. 6 is used to describe the example of control executed by the control unit 101. The control unit 101 starts a second control flow according to the flowchart shown in FIG. 6 when a predetermined condition is satisfied. When the second control flow ends, the control unit 101 repeatedly executes the second control flow at predetermined time intervals until the predetermined condition is satisfied. The conditions for starting the second control flow and the conditions for repeating the execution of the second control flow are the same as those for the first control flow in the first embodiment.

[0074] In step S11, the control unit 101 detects that the luggage is placed at the first position. If the control unit 101 detects that the luggage is placed at the first position, the process proceeds to step S12. If the control unit 101 does not detect that the luggage is placed at the first position, the process proceeds to step S13.

[0075] In step S12, the control unit 101 outputs a signal to the notification device to perform the first notification action. After performing the process of step S12, the control unit 101 ends the second control flow.

[0076] In step S13, the control unit 101 detects that the luggage is placed at the second location. If the control unit 101 detects that the luggage is placed at the second location, the control unit 101 proceeds to step S14. If the control unit 101 does not detect that the luggage is placed at the second location, the control unit 101 ends the second control flow.

[0077] In step S14, the control unit 101 outputs a signal to the alarm device to perform a second alarm operation. After performing the process of step S14, the control unit 101 ends the second control flow. If the control unit 101 does not detect that the luggage is placed at the second position in step S13, the control unit 101 may cause the alarm device to perform an alarm operation different from the first alarm operation and the second alarm operation.

[0078] By executing the second control flow, the control unit 101 can appropriately control the notification device in accordance with the position of the baggage placed on the loading platform C. By controlling the notification device, the passenger can know the state of the baggage placed on the loading platform C while traveling.

[0079] In this embodiment, when the notification device performs the first notification operation, the passenger can know that the luggage placed on the loading platform C is in a position where it is likely to fall while traveling, and can, for example, reduce the traveling speed of the human-powered vehicle 1. By being able to reduce the traveling speed of the human-powered vehicle 1, the luggage is less likely to lose balance while the human-powered vehicle 1 is traveling, and it is possible to prevent the luggage placed on the loading platform C from falling while the human-powered vehicle 1 is traveling. In this embodiment, when the notification device performs the second notification operation, the passenger can know that the luggage placed on the loading platform C is in a position where it is unlikely to fall while traveling, and can, for example, increase the traveling speed of the human-powered vehicle 1 with peace of mind. In this embodiment, after detecting whether the position of the luggage placed on the loading platform C is located in a first position where it is likely to fall, if the luggage is not located in the first position, it is detected whether the luggage is located in a second position where it is unlikely to fall, but the present invention is not limited to this embodiment. After detecting whether the luggage placed on the loading platform C is located in a first position where it is less likely to fall, if the luggage is not located in the first position, it may be detected whether the luggage is located in a second position where it is more likely to fall. After detecting whether the luggage is located in the first position where it is less likely to fall, if the luggage is not located in the first position, it may be detected whether the luggage is located in the second position where it is more likely to fall, in which case the first notification action is an action indicating that the luggage placed on the loading platform C is in a position where it is less likely to fall, and the second notification action is an action indicating that the luggage placed on the loading platform C is in a position where it is more likely to fall.

[0080] Third embodiment A control system 70 according to a third embodiment will be described. Fig. 7 is used to describe the control system 70 according to the third embodiment. The same reference numerals as those in the first and second embodiments are used for configurations common to the first and second embodiments, and duplicated descriptions will be omitted.

[0081] The pressure detection unit 110 further detects the weight of luggage placed on the loading platform C. The weight of the luggage placed on the loading platform C includes at least one of the weight of luggage placed on the main body C11 and the weight of luggage placed on the rear carrier C20. In this embodiment, the weight of the luggage placed on the loading platform C includes the weight of luggage placed on the main body C11.

[0082] The control unit 101 controls the electric component 80 in accordance with the weight of the luggage detected by the pressure detection unit 110. For example, the control unit 101 causes the alarm device to perform an alarm operation. In this embodiment, when the weight of the luggage placed on the loading platform C is equal to or greater than a first value, the control unit 101 causes the alarm device to perform a first alarm operation. The first value is set based on experiments or the like conducted in advance. The first value is stored in the storage unit 102 in advance.

[0083] The first notification operation includes an operation of notifying that the weight of the luggage placed on the loading platform C is heavy. For example, the weight of the luggage is determined to be heavy based on a first value. When performing the first notification operation, the electronic terminal 87 performs at least one of displaying a message indicating that the luggage placed on the loading platform C is heavy, generating vibrations, outputting light, and outputting sound. When performing the first notification operation, the display 88 displays a message indicating that the luggage placed on the loading platform C is heavy. When performing the first notification operation, the vibration generating device 89 generates vibrations indicating that the luggage placed on the loading platform C is heavy. When performing the first notification operation, the light generating device 90 generates light indicating that the luggage placed on the loading platform C is heavy. When performing the first notification operation, the sound generating device 91 generates sound indicating that the luggage placed on the loading platform C is heavy.

[0084] In this embodiment, when the weight of the luggage placed on the loading platform C is equal to or less than a second value, the control unit 101 causes the alarm device to perform a second alarm operation different from the first alarm operation. The second value is different from the first value. In this embodiment, the second value is smaller than the first value. The second value is set based on experiments or the like conducted in advance. The second value is stored in the memory unit 102 in advance.

[0085] The second notification operation includes an operation of notifying that the weight of the luggage placed on the loading platform C is light. For example, the weight of the luggage is determined to be light based on a second value. When performing the second notification operation, the electronic terminal 87 performs at least one of displaying a message indicating that the luggage placed on the loading platform C is light, generating vibration, outputting light, and outputting sound. When performing the second notification operation, the display 88 displays a message indicating that the luggage placed on the loading platform C is light. When performing the second notification operation, the vibration generating device 89 generates vibration indicating that the luggage placed on the loading platform C is light. When performing the second notification operation, the light generating device 90 generates light indicating that the luggage placed on the loading platform C is light. When performing the second notification operation, the sound generating device 91 generates sound indicating that the luggage placed on the loading platform C is light.

[0086] An example of control executed by the control unit 101 will be described. FIG. 7 is used to describe the example of control executed by the control unit 101. The control unit 101 starts a third control flow according to the flowchart shown in FIG. 7 when a predetermined condition is satisfied. When the third control flow ends, the control unit 101 repeatedly executes the third control flow at predetermined time intervals until the predetermined condition is satisfied. The conditions for starting the third control flow and the conditions for repeating the execution of the third control flow are the same as those for the first control flow in the first embodiment.

[0087] In step S21, the control unit 101 acquires the weight of the luggage placed on the loading platform C based on the detection signal output from the pressure detection unit 110. The control unit 101 acquires a first value by reading information from the memory unit 102. When the control unit 101 detects that the weight of the luggage placed on the loading platform C is equal to or greater than the first value based on the weight of the luggage and the first value, the control unit 101 proceeds to step S22. When the control unit 101 does not detect that the weight of the luggage is equal to or greater than the first value, the control unit 101 proceeds to step S23.

[0088] In step S22, the control unit 101 outputs a signal to the notification device to perform the first notification action. After performing the process of step S22, the control unit 101 ends the third control flow.

[0089] In step S23, the control unit 101 acquires the second value by reading information from the memory unit 102. When the control unit 101 detects that the weight of the luggage placed on the loading platform C is equal to or less than the second value based on the weight of the luggage and the second value, the control unit 101 proceeds to step S24. When the control unit 101 does not detect that the weight of the luggage is equal to or less than the second value, the control unit 101 ends the third control flow.

[0090] In step S24, the control unit 101 outputs a signal to the alarm device to perform a second alarm operation. After performing the process of step S24, the control unit 101 ends the third control flow. If the control unit 101 does not detect in step S23 that the weight of the package is equal to or less than the second value, the control unit 101 may cause the alarm device to perform an alarm operation different from the first alarm operation and the second alarm operation.

[0091] By executing the third control flow, the control unit 101 can appropriately control the notification device in accordance with the weight of the baggage placed on the loading platform C. By controlling the notification device, the passenger can know the state of the baggage placed on the loading platform C while traveling.

[0092] In this embodiment, when the notification device performs the first notification operation, the passenger can know that the luggage placed on the loading platform C is heavy while traveling, and can, for example, reduce the traveling speed of the human-powered vehicle 1. By being able to reduce the traveling speed of the human-powered vehicle 1, the luggage is less likely to lose balance while the human-powered vehicle 1 is traveling, and it is possible to prevent the luggage placed on the loading platform C from falling while the human-powered vehicle 1 is traveling. In this embodiment, when the notification device performs the second notification operation, the passenger can know that the luggage placed on the loading platform C is light while traveling, and can, for example, increase the traveling speed of the human-powered vehicle 1 with peace of mind. In this embodiment, after detecting whether the weight of the luggage placed on the loading platform C is equal to or greater than the first value, if the weight of the luggage is not equal to or greater than the first value, it is detected whether the weight of the luggage is equal to or less than the second value, but the present invention is not limited to this embodiment. After detecting whether the weight of the luggage placed on the loading platform C is equal to or less than the first value, if the weight of the luggage is not equal to or less than the first value, it may be detected whether the weight of the luggage is equal to or greater than the second value. After detecting whether the weight of the luggage is less than or equal to a first value, if the weight of the luggage is not less than or equal to the first value, the first notification operation is an operation indicating that the luggage placed on the loading platform C is light, and the second notification operation is an operation indicating that the luggage placed on the loading platform C is heavy.

[0093] In the third embodiment, the control unit 101 may control the electric component 80 according to the position of the luggage in addition to the weight of the luggage. By controlling the electric component 80 according to the position of the luggage in addition to the weight of the luggage, the control unit 101 can appropriately control the electric component 80 according to the position and weight of the luggage.

[0094] For example, in the third embodiment, when the control unit 101 detects that the weight of the luggage is equal to or greater than a first value and that the luggage is placed at a first location, the control unit 101 may cause the notification device to perform a first notification operation. For example, in the third embodiment, when the control unit 101 detects that the weight of the luggage is equal to or less than a second value and that the luggage is placed at a second location, the control unit 101 may cause the notification device to perform a second notification operation different from the first notification operation. By the notification device performing the first notification operation and the second notification operation, the passenger can know the status of the luggage placed on the loading platform C while traveling.

[0095] In the third embodiment, the control unit 101 may control an electric component 80 different from the notification device. For example, in the third embodiment, the control unit 101 may control at least one of the drive unit 81, the electric suspension 82, the electric seat post 83, the electric rear derailleur 84, the electric front derailleur 85, and the electric clutch 86. For example, in the third embodiment, the control unit 101 may set the maximum output value PM of the motor 81a of the drive unit 81.

[0096] (Fourth embodiment) A control system 70 according to a fourth embodiment will be described. Fig. 8 and Fig. 9 are used to describe the control system 70 according to the fourth embodiment. The same reference numerals as those in the first to third embodiments are used for configurations common to the first to third embodiments, and duplicated descriptions will be omitted.

[0097] Fig. 8 shows an example of a graph showing the relationship between time and motor output when a manual driving force equal to or greater than the second threshold value T2 shown in Fig. 3 is input to the pedal 13. The slope of the graph shown in Fig. 8 indicates the response speed of the motor 81a when the output of the motor 81a increases. In this specification, the response speed of the motor 81a when the output of the motor 81a increases may be referred to as the response speed of the motor 81a.

[0098] The response speed of the motor 81a includes a first response speed and a second response speed. The second response speed is different from the first response speed. In this embodiment, the second response speed is faster than the first response speed. The first response speed and the second response speed are set based on experiments or the like conducted in advance. The slope of the graph indicated by the solid line in FIG. 8 shows an example of the first response speed. The slope of the graph indicated by the two-dot chain line in FIG. 8 shows an example of the second response speed. When a manual driving force is input, the control unit 101 controls the motor 81a according to the first response speed or the second response speed.

[0099] In this embodiment, when the control unit 101 controls the motor 81a in accordance with the first response speed, the control unit 101 controls the motor 81a so that the motor output becomes the maximum output value PM of the motor 81a at time t2 when a manual driving force equal to or greater than the second threshold T2 is input to the pedal 13. When the control unit 101 controls the motor 81a in accordance with the second response speed, the control unit 101 controls the motor 81a so that the motor output becomes the maximum output value PM of the motor 81a at time t1 when a manual driving force equal to or greater than the second threshold T2 is input to the pedal 13. The time required to reach time t1 is shorter than the time required to reach time t2.

[0100] The control unit 101 sets the response speed of the motor 81a according to the position of the luggage detected by the pressure detection unit 110. In this embodiment, when the control unit 101 detects that the luggage is placed at a first position, the control unit 101 sets the response speed of the motor 81a when the output of the motor 81a increases to a first response speed. When the control unit 101 detects that the luggage is placed at a second position, the control unit 101 sets the response speed of the motor 81a when the output of the motor 81a increases to a second response speed that is faster than the first response speed.

[0101] An example of control executed by the control unit 101 will be described. FIG. 9 is used to describe the example of control executed by the control unit 101. The control unit 101 starts a fourth control flow according to the flowchart shown in FIG. 9 when a predetermined condition is satisfied. When the fourth control flow ends, the control unit 101 repeatedly executes the fourth control flow at predetermined time intervals until the predetermined condition is satisfied. The conditions for starting the fourth control flow and the conditions for repeating the execution of the fourth control flow are the same as those for the first control flow in the first embodiment.

[0102] In step S31, the control unit 101 detects that the luggage is placed at the first position. If the control unit 101 detects that the luggage is placed at the first position, the process proceeds to step S32. If the control unit 101 does not detect that the luggage is placed at the first position, the process proceeds to step S33.

[0103] In step S32, the control unit 101 sets the response speed of the motor 81a to the first response speed. After performing the process of step S32, the control unit 101 ends the fourth control flow.

[0104] In step S33, the control unit 101 detects that the luggage is placed at the second location. If the control unit 101 detects that the luggage is placed at the second location, the process proceeds to step S34. If the control unit 101 does not detect that the luggage is placed at the second location, the fourth control flow ends.

[0105] In step S34, the control unit 101 sets the response speed of the motor 81a to the second response speed. After performing the process of step S34, the control unit 101 ends the fourth control flow.

[0106] The control unit 101 executes the fourth control flow to set the response speed of the motor 81a according to the position of the luggage, thereby realizing a comfortable ride. In this embodiment, when the luggage is placed in the first position, the control unit 101 sets the response speed of the motor 81a to a first response speed that is slower than the second response speed, thereby gradually increasing the assist force of the human-powered vehicle 1. By gradually increasing the assist force of the human-powered vehicle 1, the control unit 101 can suppress an increase in the running speed of the human-powered vehicle 1 when the luggage is in a position where it is likely to fall, such as the edge of the loading platform C. By suppressing an increase in the running speed of the human-powered vehicle 1, the luggage is less likely to lose balance while the human-powered vehicle 1 is traveling, and it is possible to suppress the luggage placed on the loading platform C from falling while the human-powered vehicle 1 is traveling.

[0107] In this embodiment, when the luggage is placed at the second position, the control unit 101 sets the response speed of the motor 81a to a second response speed faster than the first response speed. By setting the response speed of the motor 81a to the second response speed faster than the first response speed, the control unit 101 quickly increases the assist force of the human-powered vehicle 1 when the luggage is in a position where it is difficult to fall, such as the center part of the loading platform C, to realize a comfortable ride. In this embodiment, after detecting whether the luggage placed on the loading platform C is placed at the first position where it is easy to fall, if the luggage is not placed at the first position, it is detected whether the luggage is placed at the second position where it is difficult to fall, but the present invention is not limited to this embodiment. After detecting whether the luggage placed on the loading platform C is placed at the first position where it is difficult to fall, if the luggage is not placed at the first position, it may be detected whether the luggage is placed at the second position where it is easy to fall. After detecting whether the luggage is located at a first position where it is less likely to fall, if the luggage is not located at the first position, the first response speed is set to a speed faster than the second response speed when detecting whether the luggage is located at a second position where it is more likely to fall.

[0108] Fifth embodiment A control system 70 according to a fifth embodiment will be described. Fig. 10 is used to describe the control system 70 according to the fifth embodiment. The same reference numerals as those in the first to fourth embodiments are used for configurations common to the first to fourth embodiments, and duplicated descriptions will be omitted.

[0109] The drive unit 81 has a plurality of operation modes. The control unit 101 is configured to be able to switch between the plurality of operation modes. The plurality of operation modes are selected in a state in which a passenger is aboard the human-powered vehicle 1. The plurality of operation modes are selected, for example, according to the position of luggage. In this embodiment, the plurality of operation modes include a first operation mode and a second operation mode.

[0110] The control unit 101 controls the output of the motor 81a in accordance with a predetermined parameter in the first operation mode and the second operation mode. In the first operation mode and the second operation mode, the output ratio of the motor 81a to the human-powered driving force input to the human-powered vehicle 1 varies in accordance with the predetermined parameter. The output ratio of the motor 81a to the human-powered driving force input to the human-powered vehicle 1 indicates the ratio between the human-powered driving force and the assist force of the human-powered vehicle 1. In this specification, the output ratio of the motor 81a to the human-powered driving force input to the human-powered vehicle 1 may be described as the output ratio of the motor 81a.

[0111] For example, in the first operation mode and the second operation mode, the output ratio of the motor 81a varies according to the traveling speed of the human-powered vehicle 1. When the traveling speed of the human-powered vehicle 1 is within a predetermined range, the output ratio of the motor 81a becomes a preset maximum value. In this specification, the maximum value of the output ratio of the motor 81a is described as the maximum output ratio of the motor 81a.

[0112] The maximum output ratio of the motor 81a in the first operation mode is set in advance to a first maximum output ratio. The maximum output ratio of the motor 81a in the second operation mode is set in advance to a second maximum output ratio. The second maximum output ratio is different from the first maximum output ratio. In this embodiment, the second maximum output ratio is greater than the first maximum output ratio. The first maximum output ratio and the second maximum output ratio are set based on experiments or the like performed in advance.

[0113] In this embodiment, the control unit 101 sets the maximum output ratio of the motor 81a by switching the operation mode of the drive unit 81. The control unit 101 sets the maximum output ratio of the motor 81a to the first maximum output ratio by switching the operation mode of the drive unit 81 to the first operation mode. The control unit 101 sets the maximum output ratio of the motor 81a to the second maximum output ratio by switching the operation mode of the drive unit 81 to the second operation mode.

[0114] The control unit 101 may set the maximum output ratio of the motor 81a without switching the operation mode of the drive unit 81. For example, the control unit 101 may set the maximum output ratio of the motor 81a by changing the maximum output ratio of the motor 81a, which is set in advance according to the operation mode, to another value.

[0115] The control unit 101 sets the maximum output ratio of the motor 81a according to the position of the luggage detected by the pressure detection unit 110. In this embodiment, when the control unit 101 detects that the luggage is placed at a first position, it sets the maximum output ratio of the motor 81a with respect to the human-powered driving force input to the human-powered vehicle 1 to a first maximum output ratio. When the control unit 101 detects that the luggage is placed at a second position, it sets the maximum output ratio of the motor 81a with respect to the human-powered driving force input to the human-powered vehicle 1 to a second maximum output ratio that is greater than the first maximum output ratio.

[0116] An example of control executed by the control unit 101 will be described. FIG. 10 is used to describe the example of control executed by the control unit 101. The control unit 101 starts a fifth control flow according to the flowchart shown in FIG. 10 when a predetermined condition is satisfied. When the fifth control flow ends, the control unit 101 repeatedly executes the fifth control flow at predetermined time intervals until the predetermined condition is satisfied. The conditions for starting the fifth control flow and the conditions for repeating the execution of the fifth control flow are the same as those for the first control flow in the first embodiment.

[0117] In step S41, the control unit 101 detects that the luggage is placed at the first position. If the control unit 101 detects that the luggage is placed at the first position, the process proceeds to step S42. If the control unit 101 does not detect that the luggage is placed at the first position, the process proceeds to step S43.

[0118] In step S42, the control unit 101 outputs a signal for switching the operation mode of the drive unit 81 to the first operation mode to the drive unit 81. After performing the process of step S42, the control unit 101 ends the fifth control flow.

[0119] In step S43, the control unit 101 detects that the luggage is placed at the second location. If the control unit 101 detects that the luggage is placed at the second location, the control unit 101 proceeds to step S44. If the control unit 101 does not detect that the luggage is placed at the second location, the control unit 101 ends the fifth control flow.

[0120] In step S44, the control unit 101 outputs a signal for switching the operation mode of the drive unit 81 to the second operation mode, to the drive unit 81. After performing the process of step S44, the control unit 101 ends the fifth control flow.

[0121] The control unit 101 executes the fifth control flow to set the maximum output ratio of the motor 81a according to the position of the luggage, thereby realizing a comfortable ride. In this embodiment, when the luggage is placed in the first position, the control unit 101 sets the maximum output ratio of the motor 81a to a first maximum output ratio that is smaller than the second maximum output ratio, thereby reducing the assisting force of the human-powered vehicle 1. By reducing the assisting force of the human-powered vehicle 1, the control unit 101 can suppress an increase in the running speed of the human-powered vehicle 1 when the luggage is in a position where it is likely to fall, such as the edge of the loading platform C. By suppressing an increase in the running speed of the human-powered vehicle 1, the luggage is less likely to lose balance while the human-powered vehicle 1 is traveling, and it is possible to suppress the luggage placed on the loading platform C from falling while the human-powered vehicle 1 is traveling.

[0122] In this embodiment, when the luggage is placed at the second position, the control unit 101 sets the maximum output ratio of the motor 81a to a second maximum output ratio that is greater than the first maximum output ratio. By setting the maximum output ratio of the motor 81a to a second maximum output ratio that is greater than the first maximum output ratio, the control unit 101 increases the assist force of the human-powered vehicle 1 when the luggage is in a position where it is difficult to fall, such as the center part of the loading platform C, to realize a comfortable ride. In this embodiment, after detecting whether the luggage placed on the loading platform C is placed at a first position where it is easy to fall, if the luggage is not placed at the first position, it is detected whether the luggage is placed at a second position where it is difficult to fall, but the present invention is not limited to this embodiment. After detecting whether the luggage placed on the loading platform C is placed at a first position where it is difficult to fall, if the luggage is not placed at the first position, it may be detected whether the luggage is placed at a second position where it is easy to fall. After detecting whether the luggage is located at a first position where it is less likely to fall, if the luggage is not located at the first position, the first maximum output ratio is set to a value larger than the second maximum output ratio when detecting whether the luggage is located at a second position where it is more likely to fall.

[0123] Sixth embodiment A control system 70 according to a sixth embodiment will be described. Fig. 11 is used to describe the control system 70 according to the sixth embodiment. The same reference numerals as those in the first to fifth embodiments are used for configurations common to the first to fifth embodiments, and duplicated descriptions will be omitted.

[0124] The control unit 101 is configured to be able to stop the motor 81a. For example, the control unit 101 outputs a stop signal to the motor 81a to stop the motor 81a. The motor 81a stops based on the stop signal output from the control unit 101.

[0125] The control unit 101 is configured to be able to acquire the running speed of the human-powered vehicle 1. The running speed of the human-powered vehicle 1 is detected by various sensors mounted on the human-powered vehicle 1. The control unit 101 can acquire the running speed of the human-powered vehicle 1 based on signals output from the various sensors.

[0126] The control unit 101 stops the motor 81a according to the position of the baggage placed on the loading platform C and the traveling speed of the human-powered vehicle 1. In this embodiment, when the control unit 101 detects that the baggage is placed at a first position, it stops the motor 81a when the traveling speed of the human-powered vehicle 1 exceeds a first traveling speed. The first traveling speed is set based on experiments or the like performed in advance. The memory unit 102 stores the first traveling speed.

[0127] In this embodiment, when it is detected that a baggage is placed at the second position, the control unit 101 stops the motor 81a when the traveling speed of the human-powered vehicle 1 exceeds a second traveling speed that is higher than the first traveling speed. The second traveling speed is set based on experiments or the like performed in advance. The memory unit 102 stores the second traveling speed.

[0128] An example of control executed by the control unit 101 will be described. FIG. 11 is used to describe the example of control executed by the control unit 101. The control unit 101 starts a sixth control flow according to the flowchart shown in FIG. 11 when a predetermined condition is satisfied. When the sixth control flow ends, the control unit 101 repeatedly executes the sixth control flow at predetermined time intervals until the predetermined condition is satisfied. The conditions for starting the sixth control flow and the conditions for repeating the execution of the sixth control flow are the same as those for the first control flow in the first embodiment.

[0129] In step S51, the control unit 101 acquires the running speed of the human-powered vehicle 1 based on signals output from various sensors. The control unit 101 acquires a first running speed by reading information from the storage unit 102. If the control unit 101 detects that a baggage has been placed at a first position and the running speed of the human-powered vehicle 1 exceeds the first running speed, the process proceeds to step S52. If the control unit 101 does not detect that a baggage has been placed at the first position and if at least one of the cases where the running speed of the human-powered vehicle 1 does not exceed the first running speed is satisfied, the process proceeds to step S53.

[0130] In step S52, the control unit 101 outputs a stop signal to the motor 81a to stop the motor 81a. After performing the process of step S52, the control unit 101 ends the sixth control flow.

[0131] In step S53, the control unit 101 acquires the second running speed by reading information from the storage unit 102. If the control unit 101 detects that a baggage has been placed at the second position and the running speed of the human-powered vehicle 1 exceeds the second running speed, the process proceeds to step S54. If at least one of the following is satisfied: the control unit 101 has not detected that a baggage has been placed at the second position, and the running speed of the human-powered vehicle 1 has not exceeded the second running speed, the control unit 101 ends the sixth control flow.

[0132] In step S54, the control unit 101 outputs a stop signal to the motor 81a to stop the motor 81a. After performing the process of step S54, the control unit 101 ends the sixth control flow.

[0133] By executing the sixth control flow, the control unit 101 can stop the motor 81a according to the position of the luggage and the running speed of the human-powered vehicle 1, realizing a comfortable run. In this embodiment, when the luggage is placed in the first position, the control unit 101 stops the motor 81a when the running speed of the human-powered vehicle 1 exceeds the first running speed. Since the first running speed is lower than the second running speed, the control unit 101 can advance the timing of stopping the assist of the human-powered vehicle 1 in association with an increase in the running speed of the human-powered vehicle 1 when the luggage is in a position where it is likely to fall, such as the edge of the loading platform C. By advancing the timing of stopping the assist of the human-powered vehicle 1, the luggage is less likely to lose balance while the human-powered vehicle 1 is running, and it is possible to prevent luggage placed on the loading platform C from falling while the human-powered vehicle 1 is running.

[0134] In this embodiment, the control unit 101 stops the motor 81a when the traveling speed of the human-powered vehicle 1 exceeds the second traveling speed when the luggage is in the second position. Since the second traveling speed is higher than the first traveling speed, the control unit 101 can easily continue to assist the human-powered vehicle 1 when the luggage is in a position where it is difficult to fall, such as the center part of the loading platform C, and realizes a comfortable ride. In this embodiment, after detecting whether the luggage placed on the loading platform C is located in the first position where it is easy to fall, if the luggage is not located in the first position, it is detected whether the luggage is located in the second position where it is difficult to fall, but the present invention is not limited to this embodiment. After detecting whether the luggage placed on the loading platform C is located in the first position where it is difficult to fall, if the luggage is not located in the first position, it may be detected whether the luggage is located in the second position where it is easy to fall. After detecting whether the luggage is located at a first position where it is less likely to fall, if the luggage is not located at the first position, and then detecting whether the luggage is located at a second position where it is more likely to fall, the first traveling speed is set to a speed faster than the second traveling speed.
