The configurations common to those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and duplicate description will be omitted. The control device 41 may or may not have the functions of the first to sixth embodiments, and may not have the functions of the first to sixth embodiments.

Bicycle anti-theft systems are known to prevent bicycle theft. The bicycle anti-theft system is unlocked by entering the password by operating the operation buttons. By the way, the PIN is a list of numbers, so it is difficult to remember. It is preferable that the method of releasing the operation restriction of the human-powered vehicle 10 is easy to remember. Hereinafter, a technique for releasing the operation restriction of the human-powered vehicle 10 will be described.

Further, at least one component 44 includes a component having a restricted operation state. The operation restriction state includes a state in which the component itself limits the operation range or a state in which the component restricts the operation of other components. It is preferable that the component having the operation-restricted state makes it difficult for the human-powered vehicle 10 to move in the operation-restricted state. For example, components having a restricted operation state include a transmission 16 and a braking device 18.

The transmission 16 shifts to the operation restricted state when the predetermined condition is satisfied. The transmission 16 takes a gear ratio higher than the intermediate gear ratio in the operation restricted state, and is in a posture in which it is difficult to shift to a state of taking another gear ratio. The operation restriction state of the transmission 16 is released by the restriction release signal of the control unit 41A. The transmission 16 takes a gear ratio lower than the gear ratio in the operation-restricted state in the operation-restricted state.

The braking device 18 shifts to the operation restricted state when the predetermined condition is satisfied. The braking device 18 takes a braking posture capable of braking the rotating body RB to be braked in the operation restricted state, and is in a state in which it is difficult to shift to another posture. The operation restriction release signal of the control unit 41A releases the operation restriction state of the braking device 18. The braking device 18 takes an allowable posture that allows the operation of the rotating body RB to be braked in the operation restriction released state.

The control device 41 includes a control unit 41A configured to release the operation restriction state of at least one component 44 of the human-powered vehicle 10 when a predetermined pattern is input to the human-powered vehicle 10. Includes at least one change in electrical connection state of at least one component 44 and at least one other component different from at least one component 44. Other components may include components among the components 44 of the human-powered vehicle 10 other than the transmission 16 and the braking device 18 whose operation is restricted by the command of the control device 41.

The component 44 shifts to the operation restricted state manually or by a command of the control unit 41A. In the present embodiment, the component 44 shifts to the restricted state by the command of the control unit 41A. Specifically, the control unit 41A is configured to change the state of at least one component 44 to the operation restricted state when at least one component 44 satisfies a predetermined condition. For example, the control unit 41A acquires cadence from the cadence sensor 30 at a predetermined cycle. The control unit 41A determines the running state of the human-powered vehicle 10 based on the cadence. The traveling state includes a stopped state in which the human-powered vehicle 10 is stopped. Further, the control unit 41A measures the stop time of the human-powered vehicle 10. The control unit 41A changes the state of the component 44 to the operation restricted state based on the stop time being longer than the predetermined time. The predetermined condition for changing the state of the component 44 to the operation restricted state is not limited to this. For example, the predetermined conditions include a predetermined operation on the operating device 24.

The control device 41 and the component 44 are connected by a cable 38. The control device 41 communicates with the component 44. Communication is done by wire. The power system and the communication system may be configured by an independent system or may be configured by a common system. In the present embodiment, the control device 41, the power storage device 42, the notification device 43, and the electric device 12 communicate by power line communication (PLC). The control unit 41A of the control device 41 monitors the connection state of each device connected to the cable 38 by power line communication. The connection state indicates whether or not the cable 38 is electrically connected. Whether or not they are electrically connected includes the concept of whether or not communication is possible.

The control unit 41A of the control device 41 is configured to release the operation-restricted state of the component 44 when a predetermined pattern is input to the human-powered vehicle 10 when the state of the component 44 is the operation-restricted state.

Preferably, the component 44 turns off the main power of the component 44 based on the transition of the component 44 to the operation restricted state. The component 44 can receive information from the control unit 41A in the off state. Upon transition to the motion restricted state, the component 44 maintains the posture immediately before transitioning to the motion restricted state. Specifically, the posture is maintained to the extent that the component 44 does not collapse unless a force that deforms it is applied. Preferably, the structure for maintaining the posture of the component 44 preferably includes mechanical engagement.

The control unit 41A detects that "a predetermined pattern is input to the human-powered vehicle 10". For example, the control unit 41A outputs an operation restriction release command to the component 44 by detecting the input of a predetermined pattern.
Preferably, the control unit 41A is configured to release the operation restriction state of the component 44 when a predetermined pattern is input to the human-powered vehicle 10 within a predetermined time after the main power supply of the component 44 is turned on. Will be done.
Specifically, the control unit 41A does not accept the input of a predetermined pattern when the component 44 is in the off state. The control unit 41A receives an input of a predetermined pattern for a period within a predetermined time after the main power supply of the component 44 is turned on. Further, the control unit 41A does not accept the input of the predetermined pattern when the predetermined time elapses after the main power supply of the component 44 is turned on. In this way, the control unit 41A receives the input of the predetermined pattern only for a predetermined period from the time when the main power of the component 44 is turned on to the elapse of the predetermined time.

The predetermined pattern includes a change in the connection state of the cable 38 connected to the component 44 and a change in the signal input based on an operation on another component. Here, the cable 38 includes those used for power line communication and power supply. "Change in the connection state of the cable 38 connected to the component 44" is a change in the connection state based on the insertion and removal of the cable 38 from the component 44, and the component 44 and the cable in the state where the component 44 and the cable 38 are connected. Includes a change in connection state based on a switch that toggles the connection with 38. When the component 44 is the transmission 16, an example of "change in the connection state of the cable 38 connected to the component 44" is "plugging / unplugging the cable 38 with respect to the transmission 16".

The "signal input change based on the operation on the other component" includes the change in the signal formed by the other component based on the operation change of the operation unit operated by the user. When the other component is the operating device 24, as an example of the "signal input change based on the operation on the other component", the "signal input change based on the switch operation of the operating device 24" can be mentioned.

The predetermined pattern includes at least one "change in the connection state of the cable 38 connected to the component 44" and at least one "change in signal input based on an operation on another component".

As an example of a predetermined pattern, a pattern performed on the following component group will be described. The operating device 24 has a right switch 24R and a left switch 24L. The right switch 24R is attached to, for example, the right side of the steering device ST. The left switch 24L is attached to, for example, the left side of the steering device ST. One of the right switch 24R and the left switch 24L is a switch that shifts up the transmission 16 and the other is a switch that shifts down the transmission 16.

In such a group of components, the predetermined pattern includes four elements. The "first" to "fourth" indicate the input order for the human-powered vehicle 10. The first element is a change in the input signal input to the control unit 41A when the right switch 24R is pressed. The second element is a change in the input signal input to the control unit 41A when the left switch 24L is pressed. The third element is a change in which the connection state between the transmission 16 and the cable 38 becomes a non-connection state as the cable 38 is pulled out from the transmission 16. The fourth element is a change in which the non-connected state of the transmission 16 and the cable 38 becomes a connected state as the cable 38 is inserted from the transmission 16. The control unit 41A forms the above-mentioned restriction release signal based on detecting a predetermined pattern.

Preferably, the control unit 41A is configured to receive the change information and change the predetermined pattern based on the received change information. For example, the change of the predetermined pattern is performed via the notification device 43. The notification device 43 includes a cycle computer 43A having a display screen. It is preferable that the notification device 43 can communicate with the control unit 41A. The notification device 43 may be connected to the cable 38. For example, the notification device 43 communicates with the control device 41 by power line communication. In the present embodiment, the notification device 43 has a touch panel.

The notification device 43 reads a predetermined pattern from the control unit 41A and displays the predetermined pattern on the display screen. The notification device 43 has an application for changing a predetermined pattern. The application displays a plurality of elements constituting the predetermined pattern in the order of the predetermined pattern. The application accepts the user's selection operation as change information and determines the elements of each order of the predetermined pattern.

FIG. 6 is an example of the operation screen 60 of the application. The display image shown in FIG. 6 is an operation image for changing the first of the predetermined patterns. In this example, eight elements are displayed as selectable elements. The first element is "pressing the right switch 24R of the operating device 24". The second element is "pressing the left switch 24L of the operating device 24". The third element is "operate the right brake lever". The fourth element is "operate the left brake lever". The fifth element is "to change the cable 38 of the transmission 16 from the connected state to the disconnected state". The sixth element is "to change the cable 38 of the transmission 16 from the unconnected state to the connected state". The seventh element is "to change the cycle computer 43A from the disconnected state to the connected state". The eighth element is "to set the saddle SD at a predetermined position (height)". Further, the operation image shows "change" and "cancel". By touching "Change", the first element is changed from the element before the change to the selected element. By touching "Cancel", the first element is maintained as it is without being changed by the element before the change.

The operation of the control unit 41A when a predetermined pattern is input to the human-powered vehicle 10 will be described with reference to FIG. 7. As described above, the control unit 41A receives a predetermined pattern for a reception period from the time when the component 44 is in the operation restricted state and the main power supply of the component 44 is turned on to a predetermined time. During the reception period, the control unit 41A executes the flowchart shown in FIG. 7 at a predetermined cycle. At the first timing of the predetermined cycle, the control unit 41A shifts to step S11 of the flowchart shown in FIG. 7 and starts the flow.

In step S11, the control unit 41A determines whether or not the right switch 24R of the operating device 24 is pressed. In step S11, when the control unit 41A determines that the right switch 24R has been pressed (YES determination), the control unit 41A shifts to the next step S12, and when the other determination (NO determination), the control unit 41A Ends the flow and waits until the start of the next cycle.

In step S12, the control unit 41A determines whether or not the left switch 24L of the operating device 24 is pressed. When the control unit 41A determines in step S12 that the left switch 24L has been pressed, the control unit 41A shifts to the next step S13, and when the other determination (NO determination) is made, the control unit 41A ends the flow. Then wait until the start of the next flow.

In step S13, the control unit 41A determines whether or not the cable 38 of the transmission 16 is changed from the connected state to the disconnected state. In step S13, when the control unit 41A determines that the cable 38 of the transmission 16 has changed from the connected state to the disconnected state, the control unit 41A shifts to the next step S14, and the other determination (NO determination) is made. At that time, the control unit 41A ends the flow and waits until the start time of the next cycle.

In step S14, the control unit 41A determines whether or not the cable 38 of the transmission 16 is changed from the disconnected state to the connected state. In step S14, when the control unit 41A determines that the cable 38 of the transmission 16 has changed from the disconnected state to the connected state, the control unit 41A shifts to the next step S15, and the control unit 41A sends an operation restriction release signal. Is generated, and the operation restriction state of the component 44 is released. At the time of other determination (NO determination), the control unit 41A ends the flow and waits until the start of the next cycle.

The operation of the above embodiment will be described. The predetermined pattern for releasing the operation restricted state of the component 44 includes, as described above, a change in the electrical connection state of at least one of the component 44 and the other components. Since the change in the electrical connection state is accompanied by a human operation (operation other than the operation of only the hand) such as the connection / disconnection of the cable 38 and the operation of the switch, it is easy for the person to remember and is hard to forget. Further, since the input of a predetermined pattern involves a human movement, decoding by random number input can be suppressed, and the crime prevention property is high.
