In the auxiliary stop mode, for example, the auxiliary control unit 48 is configured to control the motor 46 in a manner that allows the auxiliary unit 42 to not assist in the propulsion of the manually driven vehicle 10.

[0095] The auxiliary control unit 48 is configured, for example, in auxiliary mode, to control the motor 46 in such a way that it outputs an auxiliary force based on the human-powered driving force input to the human-powered vehicle 10. The human-powered driving force corresponds, for example, to the driving force output to at least one first rotating body 34 by rotating the crankshaft 20 through a user. The auxiliary force includes, for example, the driving force output to the first rotating body 34 by rotating the motor 46. The auxiliary force corresponds to the assistance provided by the auxiliary unit 42 in propelling the human-powered vehicle 10. The human-powered driving force and the auxiliary force can be represented by torque or power.

[0096] The auxiliary control unit 48 is configured, for example, to control the motor 46 in an auxiliary mode such that the auxiliary level of the motor 46 is a predetermined auxiliary level. The auxiliary level includes, for example, at least one of the auxiliary ratio of the auxiliary force of the auxiliary unit 42 to the human driving force input to the human-powered vehicle 10, and the maximum auxiliary value of the auxiliary force of the auxiliary unit 42.

[0097] When the assistance level includes an assistance ratio, the predetermined assistance level includes a predetermined assistance ratio. The assistance control unit 48 is configured, for example, to control the motor 46 such that the assistance ratio becomes the predetermined assistance ratio. The predetermined assistance ratio is configured to be changeable by the user manually driving the vehicle 10. The predetermined assistance ratio can also be changed according to the magnitude of the manual driving force. For example, the greater the manual driving force, the greater the predetermined assistance ratio will be changed by the assistance control unit 48.

[0098] When the assistance level includes an assistance maximum value, the predetermined assistance level includes the predetermined assistance maximum value. The assistance control unit 48 is configured, for example, to control the motor 46 in a manner that makes the assistance maximum value less than or equal to the predetermined assistance maximum value. The predetermined assistance maximum value is determined, for example, by at least one of the output characteristics of the motor 46 and the control mode. The predetermined assistance maximum value is configured to be changeable by the user of the manually driven vehicle 10.

[0099] The auxiliary modes may include, for example, a first auxiliary mode and a second auxiliary mode with an auxiliary level greater than the first auxiliary mode. The auxiliary modes may also include a third auxiliary mode with an auxiliary level greater than the second auxiliary mode. When the auxiliary level includes an auxiliary ratio, the predetermined auxiliary ratio in the second auxiliary mode is greater than the predetermined auxiliary ratio in the first auxiliary mode. When the auxiliary level includes a maximum auxiliary value, the predetermined maximum auxiliary value in the second auxiliary mode is greater than the predetermined maximum auxiliary value in the first auxiliary mode. The auxiliary modes may also include a third auxiliary mode with an auxiliary level greater than the second auxiliary mode.

[0100] like Figure 1 as well as Figure 3 As shown, the auxiliary operating device 44 is provided, for example, in a user-operable part of the human-powered vehicle 10. The auxiliary operating device 44 is provided, for example, on the frame 14. In this embodiment, the auxiliary operating device 44 is mounted on the frame 16. The auxiliary operating device 44 is provided, for example, on the top tube 16B of the frame 16. The auxiliary operating device 44 can also be detachably mounted on the frame 14. The auxiliary operating device 44 can also be mounted on the handlebars 28. The auxiliary operating device 44 can also be, for example, a bicycle computer mounted on the handlebars 28.

[0101] like Figure 2 As shown, the auxiliary operation device 44 includes, for example, an auxiliary operation control unit 54. The auxiliary operation control unit 54 includes, for example, a processing unit that executes a predetermined control program. The processing unit included in the auxiliary operation control unit 54 includes, for example, a CPU or an MPU. The processing unit included in the auxiliary operation control unit 54 can also be located in multiple mutually separate locations. One part of the processing unit can be located in the manually driven vehicle 10, and another part can be located in a server connected to the Internet. When the processing unit is located in multiple mutually separate locations, the parts of the processing unit are connected to each other via a wireless communication device in a manner capable of communication. The auxiliary operation control unit 54 can also include one or more microcomputers.

[0102] The auxiliary operation control unit 54 may also include an auxiliary operation storage unit. The auxiliary operation storage unit stores, for example, control programs and information used in control processing. The auxiliary operation storage unit may include, for example, non-volatile memory and volatile memory.

[0103] The auxiliary operation control unit 54 can be connected to the auxiliary control unit 48 in a communicable manner, for example, via wired communication. The auxiliary operation control unit 54 can also communicate with the auxiliary control unit 48 via, for example, power line communication (PLC), CAN, or UART. Alternatively, the auxiliary operation control unit 54 can be connected to the auxiliary control unit 48 in a communicable manner via wireless communication.

[0104] like Figure 2 and Figure 3 As shown, the auxiliary operation device 44 includes an operation unit 56. The auxiliary operation device 44 is configured to transmit operation signals to the auxiliary unit 42 via wired communication based on user operations on the operation unit 56. When the operation unit 56 is operated by the user, for example, the auxiliary operation control unit 54 sends an operation signal to the auxiliary control unit 48. The operation signal may include, for example, a signal for controlling the auxiliary unit 42. The operation signal may include, for example, an operation signal for changing the auxiliary mode. The operation signal may also include a signal for putting the auxiliary unit 42 into sleep mode or stopping the supply of power to the auxiliary unit 42. When the auxiliary control unit 48 receives an operation signal for changing the auxiliary mode, it changes the auxiliary mode, for example, based on the received operation signal.

[0105] The operation unit 56 includes, for example, a first operation unit 56A, a second operation unit 56B, a third operation unit 56C, and a display unit 56D. The first operation unit 56A is, for example, a power switch. When the first operation unit 56A is operated in the auxiliary control mode (auxiliary stop mode), the auxiliary operation device 44 sends a first operation signal to the auxiliary unit 42 to start the auxiliary operation. Upon receiving the first operation signal, the auxiliary unit 42 switches the auxiliary control mode from the auxiliary stop mode to the auxiliary mode.

[0106] When the first operation unit 56A is operated, for example, in the auxiliary control mode, the auxiliary operation device 44 sends a second operation signal to the auxiliary unit 42 to stop the assistance. Upon receiving the second operation signal, the auxiliary unit 42 switches the auxiliary control mode from the auxiliary mode to the auxiliary stop mode. The first operation unit 56A may also include a switch for sending the first operation signal to the auxiliary unit 42 and a switch for sending the second operation signal to the auxiliary unit 42.

[0107] The second operation unit 56B and the third operation unit 56C are, for example, switches for changing the assistance level. For instance, when the second operation unit 56B is operated, the auxiliary operation device 44 sends a third operation signal to the auxiliary unit 42 to increase the assistance level. Upon receiving the third operation signal, the auxiliary unit 42 switches the assistance mode to another assistance mode to increase the assistance level. For example, if the auxiliary unit 42 receives the third operation signal while the assistance mode is in the first assistance mode, it switches the assistance mode from the first assistance mode to the second assistance mode.

[0108] For example, when the third operation unit 56C is operated, the auxiliary operation device 44 sends a fourth operation signal to the auxiliary unit 42 to reduce the auxiliary level. Upon receiving the fourth operation signal, the auxiliary unit 42 switches the auxiliary mode to another auxiliary mode to reduce the auxiliary level. For example, if the auxiliary unit 42 receives the fourth operation signal while the auxiliary mode is the second auxiliary mode, it switches the auxiliary mode from the second auxiliary mode to the first auxiliary mode. The second operation unit 56B and the third operation unit 56C can also be used as switches for selecting auxiliary modes other than the first auxiliary mode.

[0109] Display unit 56D displays, for example, the status of auxiliary unit 42. Display unit 56D also displays, for example, the current auxiliary control mode. The remaining battery level of battery 40 can also be displayed on display unit 56D. The status of the manually operated vehicle 10 can also be displayed on display unit 56D. Furthermore, the status of other manually operated electric components installed on the manually operated vehicle 10 besides auxiliary unit 42 can also be displayed on display unit 56D.

[0110] The auxiliary operation device 44 includes, for example, an auxiliary operation communication unit 58. The auxiliary operation communication unit 58 is configured to wirelessly communicate with the transmission device 62 of the control system 60 and the transmission operation device 64 of the control system 60.

[0111] like Figure 1 and Figure 2 As shown, the manually driven vehicle 10 includes a control system 60. The control system 60 includes a transmission device 62 and a transmission operation device 64 for operating the transmission device 62. The control system 60 may also include, for example, an auxiliary unit 42 and an auxiliary operation device 44. The control system 60 may also include a first control system 60A and a second control system 60B, where the first control system 60A includes the transmission device 62 and the transmission operation device 64, and the second control system 60B includes the auxiliary unit 42 and the auxiliary operation device 44. For example, the component groups included in the first control system 60A form a first communication group, and the component groups included in the second control system 60B form a second communication group. A portion of the component groups included in the first control system 60A may also be included in the second control system 60B. A portion of the component groups included in the second control system 60B may also be included in the first control system 60A.

[0112] The transmission device 62 is configured to perform a gear-changing operation that alters the gear ratio of the manually driven vehicle 10. The gear ratio is, for example, the ratio of the rotational speed of the wheel 12 to the rotational speed of the crankshaft 20. The rotational speed of the wheel 12 includes, for example, the rotational speed of the drive wheel. The transmission device 62 is, for example, provided in the transmission path of the human-powered drive force in the manually driven vehicle 10.

[0113] The derailleur 62 includes, for example, at least one of a derailleur 62A and an internal derailleur. In this embodiment, the derailleur 62 includes a derailleur 62A. When the derailleur 62 includes a derailleur 62A, the transmission body 38 includes a chain. The transmission body 38 may also include a belt. The derailleur 62A includes, for example, an electric actuator. The electric actuator is configured, for example, to actuate the derailleur 62A. When the derailleur 62 includes an internal derailleur, the internal derailleur is, for example, located at the hub of the rear wheel 12R.

[0114] Derailleur 62A is configured, for example, to operate the transmission 38 to change the gear ratio. Derailleur 62A changes the gear ratio by switching the transmission 38 from one of a plurality of rotating bodies to another. In the case where the rotating bodies include sprockets, the plurality of rotating bodies may each include rotating bodies with different numbers of teeth.

[0115] Derailleur 62A is configured, for example, to move a transmission body 38, which engages with one of a plurality of rotating bodies, to another of the plurality of rotating bodies. The plurality of rotating bodies includes, for example, a plurality of sprockets. Derailleur 62A is configured, for example, to move a transmission body 38, which engages with one of the plurality of sprockets, to another of the plurality of sprockets.

[0116] At least one first rotating body 34 may include, for example, a plurality of first rotating bodies 34. At least one second rotating body 36 may include, for example, a plurality of second rotating bodies 36. A plurality of rotating bodies may include, for example, at least one of a plurality of first rotating bodies 34 and a plurality of second rotating bodies 36. A plurality of first rotating bodies 34 may include, for example, a plurality of first sprockets. A plurality of second rotating bodies 36 may include, for example, a plurality of second sprockets. A plurality of rotating bodies may include, for example, at least one of a plurality of first sprockets and a plurality of second sprockets.

[0117] The derailleur 62A is configured, for example, to perform a gear shifting operation. During the gear shifting operation, the derailleur 62A changes the engagement state of multiple rotating bodies with the transmission body 38 by operating the transmission body 38, thereby changing the gear ratio.

[0118] The transmission device 62 performs speed changing operations, for example, by changing the gear. The transmission device 62 is configured to select one gear from multiple gears. For example, different gear ratios are set for each of the multiple gears. For example, the higher the gear, the larger the gear ratio. The gears are set, for example, according to the number of teeth of the multiple rotating bodies.

[0119] The gear shifting operation includes upshifting and downshifting. For example, the gear shifting device 62 is configured to perform an upshifting operation, changing from one of multiple gears to another, thereby increasing the gear ratio. For example, the gear shifting device 62 is configured to perform a downshifting operation, changing from one of multiple gears to another, thereby decreasing the gear ratio.

[0120] The derailleur 62A is configured, for example, as an operating transmission 38 to change from one of a plurality of gears to another. The plurality of gears are set, for example, according to at least one of a plurality of rotating bodies.

[0121] Derailleur 62A, for example, moves a chain engaged with one of a plurality of sprockets to another of the plurality of sprockets. Derailleur 62A includes, for example, a rear derailleur and a front derailleur. The gear ratio of each gear is set, for example, based on a combination of one of a plurality of first sprockets and one of a plurality of second sprockets.

[0122] Derailleur 62A may also include only one of the rear derailleur and the front derailleur. When derailleur 62A includes only the rear derailleur, the gear ratio of each shifter is set according to one of the plurality of second sprockets. When derailleur 62A includes only the front derailleur, the gear ratio of each shifter is set according to one of the plurality of first sprockets.

[0123] The rear derailleur selects one of a plurality of second sprockets based on the selected shift gear. The rear derailleur moves the chain to engage the selected sprocket. When the highest shift gear is selected, the sprocket with the fewest teeth among the multiple second sprockets is selected by the rear derailleur. When the lowest shift gear is selected, the sprocket with the most teeth among the multiple second sprockets is selected by the rear derailleur.

[0124] The front derailleur selects one of a plurality of first sprockets based on the selected shift gear. The front derailleur moves the chain to engage the chain with the selected sprocket. When the highest shift gear is selected, the sprocket with the fewest teeth among the plurality of first sprockets is selected by the front derailleur. When the lowest shift gear is selected, the sprocket with the most teeth among the plurality of first sprockets is selected by the front derailleur.

[0125] At least one of the plurality of rotating bodies may include a shift-promoting region that facilitates shifting action of the shifting device 62. The shift-promoting region is an area that facilitates movement of the transmission body 38, based on the derailleur 62A, from one of the plurality of rotating bodies to an adjacent one of the plurality of rotating bodies. The shift-promoting region may, for example, have a recess formed on the side of the sprocket and at least one of the teeth of the sprocket. The shift-promoting region includes at least one of a first shifting region that facilitates upshifting operation and a second shifting region that facilitates downshifting operation.

[0126] The gear shifting device 62 includes a first communication unit 66A, an actuator 68, and a gear shifting control unit 70. The first communication unit 66A is, for example, a communication device. The actuator 68 is configured to perform a gear shifting operation. The actuator 68 corresponds, for example, to the electric actuator of the derailleur 62A.

[0127] The transmission control unit 70 includes, for example, a processing unit that executes a predetermined control program. The processing unit included in the transmission control unit 70 may include, for example, a CPU or an MPU. The processing unit included in the transmission control unit 70 may also be located in multiple, mutually separate locations. One part of the processing unit may be located in the manually driven vehicle 10, and another part may be located in a server connected to the Internet. When the processing unit is located in multiple, mutually separate locations, the different parts of the processing unit are connected to each other via a wireless communication device in a manner capable of communication. The transmission control unit 70 may also include one or more microcomputers.

[0128] The transmission control unit 70 may also include a transmission storage unit. The transmission storage unit stores, for example, control programs and information used in control processing. The transmission storage unit may include, for example, non-volatile memory and volatile memory.

[0129] The transmission device 62 may include a communication unit 66, for example. The communication unit 66 may be a communication device. The communication unit 66 may be configured to communicate with the auxiliary operation device 44 and the transmission operation device 64. The auxiliary operation device 44 is configured to operate the auxiliary unit 42 that assists in the propulsion of the manually driven vehicle 10, and the transmission operation device 64 is configured to operate the transmission device 62. The transmission device 62 may include a second communication unit 66B, for example. The second communication unit 66B may be a communication device. The communication unit 66 may include a first communication unit 66A and a second communication unit 66B.

[0130] The transmission device 62 may also include, for example, a substrate 72 on which a first communication unit 66A and a second communication unit 66B are mounted. The substrate 72 may include, for example, a printed circuit board. A transmission control unit 70 may be mounted on the substrate 72. The substrate 72 may be housed within a housing of the transmission device 62.

[0131] The transmission unit 62 also includes, for example, a cable connector 74 configured to connect a cable 40A. The cable 40A is configured to connect to the battery 40. The cable connector 74 includes, for example, a socket for inserting a connector of the cable 40A. The cable connector 74 is, for example, provided on the outer surface of the housing of the transmission unit 62. The cable connector 74 is electrically connected to the base plate 72. Power from the battery 40 is supplied to the communication unit 66, the transmission control unit 70, and the actuator 68 via the cable connector 74.

[0132] The communication unit 66 is configured, for example, to wirelessly communicate with the auxiliary operating device 44 and the transmission device 62. The communication unit 66 may include, for example, an antenna for wirelessly communicating with the auxiliary operating device 44 and the transmission device 62. The communication unit 66 may also be configured to perform wired communication with the auxiliary operating device 44 and the transmission device 62.

[0133] The first communication unit 66A communicates with the auxiliary operating device 44, for example, via a first communication method, and the second communication unit 66B communicates with the transmission operating device 64, for example, via a second communication method. The second communication method is, for example, different from the first communication method.

[0134] The first communication method is, for example, wireless communication using a wireless signal at a first frequency, and the second communication method is wireless communication using a wireless signal at a second frequency different from the first frequency. The first frequency is, for example, a frequency within the 2.4 GHz band. The first communication method is, for example, Bluetooth (registered trademark). The second frequency is, for example, a frequency greater than or less than the first frequency.

[0135] At least one of the first communication unit 66A and the second communication unit 66B is configured to be capable of changing frequencies. For example, the first communication unit 66A is configured to be capable of changing a first frequency, and the second communication unit 66B is configured not to change a second frequency. The first communication unit 66A is configured, for example, to be capable of changing the first frequency within a predetermined frequency range. When both the first communication unit 66A and the second communication unit 66B are configured to be capable of changing frequencies, the predetermined range of the first frequency that the first communication unit 66A can change to may be the same as or different from the predetermined range of the second frequency that the second communication unit 66B can change to. Alternatively, both the first communication unit 66A and the second communication unit 66B may be configured not to change frequencies.

[0136] The transmission control unit 70 is configured, for example, to control the communication unit 66 according to a communication control state. The communication control state includes a first communication control state and a second communication control state. The transmission control unit 70 is configured, for example, to switch the communication control state from one of the first communication control state and the second communication control state to the other. The transmission control unit 70 is configured, for example, in the first communication control state, to control the communication unit 66 so that it communicates with the auxiliary operating device 44 via a first communication method. The transmission control unit 70 is configured, for example, in the second communication control state, to control the communication unit 66 so that it communicates with the transmission operating device 64 via a second communication method.

[0137] The transmission control unit 70 is configured, for example, to control the first communication unit 66A and the second communication unit 66B according to a communication control state. In the first communication control state, the transmission control unit 70 is configured to control the first communication unit 66A to communicate with the auxiliary operating device 44 via a first communication method. In the second communication control state, the transmission control unit 70 is configured to control the second communication unit 66B to communicate with the transmission operating device 64 via a second communication method.

[0138] For example, when the communication control state is the first communication control state, the transmission control unit 70 controls the communication unit 66 in a manner that enables the first communication unit 66A to receive the first transmission command while preventing the second communication unit 66B from receiving the second transmission command. For example, when the communication control state is the second communication control state, the transmission control unit 70 controls the communication unit 66 in a manner that prevents the first communication unit 66A from receiving the first transmission command while enabling the second communication unit 66B to receive the second transmission command.

[0139] The transmission mechanism 62 includes, for example, an operation input unit 76. The operation input unit 76 includes, for example, at least one of a button, a dial, and a lever. The transmission control unit 70 changes the communication control state by operating the operation input unit 76. The operation input unit 76 may also be located externally to the transmission mechanism 62. The operation input unit 76 may also be located on the transmission operation device 64. The operation input unit 76 may also be configured to be located in at least one of a personal computer, tablet computer, and smartphone, and connected to the transmission mechanism 62 in a wired or wireless manner. In the case where the operation input unit 76 is located in at least one of a personal computer, tablet computer, and smartphone, for example, the user operates the operation input unit 76 before boarding the human-powered vehicle 10.

[0140] The transmission control unit 70 can also change the communication control state independently of the operation input unit 76. For example, the transmission control unit 70 changes the communication control state based on the state of power supply to the transmission 62. For example, the transmission control unit 70 changes the communication control state based on whether the transmission 62 is connected to the battery 40. For example, the manual transmission vehicle 10 may include a transmission battery different from the battery 40. When the transmission 62 is not connected to the battery 40, the transmission 62 may be configured to receive power from the transmission battery. The transmission 62 may also have a storage section for storing the transmission battery.

[0141] For example, when the transmission 62 is connected to the battery 40, the transmission control unit 70 switches the communication control state to a first communication control state. For example, when the transmission 62 is not connected to the battery 40, the transmission control unit 70 switches the communication control state to a second communication control state. The transmission control unit 70 can also switch the communication control state to the second communication control state when power is supplied to the transmission 62 from the transmission battery. If the transmission 62 has a storage compartment for storing the transmission battery, the transmission control unit 70 can also change the communication control state based on whether or not the transmission battery is being stored in the storage compartment. The transmission 62 can also determine whether power is being supplied to the transmission 62 from the transmission battery based on whether or not the transmission battery is being stored in the storage compartment. By changing the communication control state based on the state of power supply to the transmission 62, in the case where the manual transmission vehicle 10 does not include the auxiliary unit 42, the transmission control unit 70 can switch the communication control state to the second communication control state. Therefore, the communication control state is changed even if the user does not perform any operation, thus improving availability.

[0142] The transmission control unit 70 changes the communication control state, for example, based on the connection status of the cable 40A to the cable connector 74. When the cable 40A is connected to the cable connector 74, the transmission control unit 70 can also switch the communication control state to a first communication control state. When the cable 40A is not connected to the cable connector 74, the transmission control unit 70 can also switch the communication control state to a second communication control state.

[0143] For example, when the communication network of the control system 60 is configured, the operator sets a communication control state. For example, when the operator wants to configure the communication network of the control system 60 to control the transmission 62 using the auxiliary operating device 44, the operator operates the operation input unit 76 by selecting a first communication control state. For example, when the operator wants to configure the communication network of the control system 60 so that the auxiliary operating device 44 does not control the transmission 62, the operator operates the operation input unit 76 by selecting a second communication control state. The operator can be a user or a manufacturer. When the communication network of the control system 60 is configured so that the auxiliary operating device 44 does not control the transmission 62, for example, in a manually operated vehicle 10 that does not have an auxiliary operating device 44 capable of controlling the transmission 62.

[0144] Reference Figure 4 This explains the processing of changes in communication control status. For example, when power is supplied to the transmission control unit 70, the transmission control unit 70 begins processing and transfers to... Figure 4 Step S11 of the flowchart shown. If Figure 4Once the flowchart ends, the transmission control unit 70, for example, repeatedly performs the processing from step S11 after a predetermined cycle until the power supply stops.

[0145] In step S11, the transmission control unit 70 determines whether a communication control state change request exists. For example, if the operation input unit 76 is operated, the transmission control unit 70 determines that a communication control state change request exists. If a communication control state change request exists, the transmission control unit 70 proceeds to step S12. If no communication control state change request exists, the transmission control unit 70 terminates the process. The transmission control unit 70 may also determine the existence of a communication control state change request based on at least one of the following: whether the transmission device 62 is connected to the battery 40; whether the transmission device battery is stored in the storage unit; whether the cable 40A is connected to the cable connection unit 74; and whether the transmission device 62 is connected to the auxiliary operation device 44.

[0146] In step S12, the transmission control unit 70 determines whether the communication control state is the first communication control state. If the communication control state is the first communication control state, the transmission control unit 70 proceeds to step S13. In step S13, the transmission control unit 70 switches the communication control state to the second communication control state and ends the process.

[0147] If the communication control state is not the first communication control state in step S12, the transmission control unit 70 proceeds to step S14. In step S14, the transmission control unit 70 switches the communication control state to the first communication control state and ends the process.

[0148] The transmission operation device 64 includes a transmission operation control unit 78. The transmission operation control unit 78 includes, for example, a processing unit that executes a predetermined control program. The processing unit included in the transmission operation control unit 78 includes, for example, a CPU or an MPU. The processing unit included in the transmission operation control unit 78 can also be located in multiple mutually separate locations. One part of the processing unit can be located in the manually driven vehicle 10, and another part can be located in a server connected to the Internet. When the processing unit is located in multiple mutually separate locations, the different parts of the processing unit are connected to each other via a wireless communication device in a manner capable of communication. The transmission operation control unit 78 can also include one or more microcomputers.

[0149] The shift operation device 64 includes, for example, a shift operation storage unit 80. The shift operation storage unit 80 is connected to the shift operation control unit 78 via, for example, a wired or wireless connection. The shift operation storage unit 80 stores, for example, control programs and information used for control processing. The shift operation storage unit 80 includes, for example, non-volatile memory and volatile memory.

[0150] The transmission operation device 64 includes, for example, at least one transmission operation unit 82 for receiving user input. The transmission operation unit 82 includes, for example, at least one of a button, a dial, and a lever. The transmission operation unit 82 may also include two operation units corresponding to upshifting and downshifting operations, respectively. The transmission operation control unit 78 generates transmission commands based on the operation of the transmission operation unit 82. The transmission commands include, for example, commands for upshifting or downshifting.

[0151] The shifting operation device 64 includes, for example, a shifting operation communication unit 84. The shifting operation device 64 is configured, for example, to communicate with the auxiliary operation device 44 via a first communication method. The shifting operation device 64 is also configured, for example, to communicate with the shifting device 62 via a second communication method. The shifting operation communication unit 84 communicates with the auxiliary operation communication unit 58 via the first communication method and with the second communication unit 66B via the second communication method. The shifting operation communication unit 84 may also include a first shifting operation communication unit using the first communication method and a second shifting operation communication unit using the second communication method.

[0152] The shift operation control unit 78 is configured, for example, to select which of the first and second communication methods to use to send the shift command. The shift operation control unit 78 is configured, for example, to select which of the first and second communication methods to use to send the shift command based on the communication control state of the shift device 62. The shift operation control unit 78 is configured, for example, to use the first communication method to send the shift command when the communication control state of the shift device 62 is the first communication control state. The shift operation control unit 78 is configured, for example, to use the second communication method to send the shift command when the communication control state of the shift device 62 is the second communication control state. The shift operation unit 82 may switch communication methods based on the operation of the operation input unit 76, and may also include a switching operation unit for switching the communication method of the shift operation communication unit 84. The shift operation control unit 78 may also be configured to receive the current communication control state from the shift control unit 70.

[0153] The shift control unit 78 is configured to wirelessly transmit a first command to the auxiliary operation device 44. The auxiliary operation communication unit 58 of the auxiliary operation device 44, for example, wirelessly receives the first command. The first command is, for example, a shift command. The shift control unit 78 is configured, for example, to cause the shift operation communication unit 84 to send the first command based on a user operation input to the shift operation unit 82. The shift control unit 78 is configured, for example, to cause the shift operation communication unit 84 to send the first command based on a user operation input to the shift operation unit 82 when the communication control state is in the first communication control state.

[0154] When the communication control state is in the second communication control state, the shift operation control unit 78 is configured to wirelessly transmit a second shift command to the shifting device 62. When the communication control state is in the second communication control state, the shifting device 62 receives the second shift command from the shifting operation device 64, for example, without via the auxiliary operation device 44. When the communication control state is in the second communication control state, the shift operation control unit 78 is configured, for example, to cause the shift operation communication unit 84 to send the second shift command based on a user operation input to the shift operation unit 82.

[0155] When the auxiliary operation control unit 54 receives the first instruction from the auxiliary operation communication unit 58, it sends, for example, a first gear shifting instruction to the gear shifting device 62. The first gear shifting instruction is a signal used to cause the gear shifting device 62 to perform a gear shifting operation. The first communication unit 66A of the gear shifting device 62 is configured, for example, to wirelessly receive the first gear shifting instruction. The first communication unit 66A is configured, for example, to wirelessly receive the first gear shifting instruction sent from the auxiliary operation device 44 via a first communication method. The first communication unit 66A is configured to receive the first gear shifting instruction sent from the auxiliary operation device 44 based on the auxiliary operation device 44's receipt of the first instruction.

[0156] The shifting operation device 64 is configured, for example, to wirelessly transmit a second shifting command to the shifting device 62. The second shifting command is a signal used to cause the shifting device 62 to perform a shifting operation. The second communication unit 66B is configured, for example, to wirelessly receive the second shifting command transmitted from the shifting operation device 64 via a second communication method. The second communication unit 66B is configured, for example, to wirelessly receive the second shifting command. The second shifting command is, for example, a shifting command. The shifting operation control unit 78 is configured, for example, to cause the shifting operation communication unit 84 to transmit the second shifting command based on a user operation input to the shifting operation unit 82. The shifting operation control unit 78 is configured, for example, to cause the shifting operation communication unit 84 to transmit the second shifting command based on a user operation input to the shifting operation unit 82 when the communication control state is in the second communication control state.

[0157] The transmission control unit 70 is configured to control the actuator 68 based on transmission commands. The transmission control unit 70 performs transmission operations by actuating the actuator 68. Based on the received transmission commands, the transmission control unit 70 performs upshift or downshift operations.

[0158] The transmission control unit 70 is configured to control the actuator 68 to perform a transmission operation based on a first transmission command. When the first communication unit 66A receives the first transmission command, the transmission control unit 70 performs an upshift or downshift operation based on the received command. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation upon receiving the first transmission command from the first communication unit 66A. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation when the first communication unit 66A receives the first transmission command. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation when the transmission start timing is reached after the first communication unit 66A receives the first transmission command.

[0159] The transmission control unit 70 controls the actuator 68 to perform a transmission operation based on the second transmission command. When the second communication unit 66B receives the second transmission command, the transmission control unit 70 performs an upshift or downshift operation based on the received command. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation upon receiving the second transmission command from the second communication unit 66B. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation when the second communication unit 66B receives the second transmission command. For example, the transmission control unit 70 is configured to control the actuator 68 to start the transmission operation when the transmission start timing is reached after the second communication unit 66B receives the second transmission command.

[0160] The communication unit 66 can also transmit the status of the transmission device 62 to a manually operated electric component that is different from the transmission device 62. The communication unit 66 can transmit at least one of the start and end of the transmission operation to the auxiliary unit 42, and can also transmit at least one of the start and end of the actuator 68's operation during the transmission operation. For example, the communication unit 66 can also transmit the current gear in the transmission device 62 to the auxiliary operation device 44. The auxiliary operation device 44 can also display the current gear in the transmission device 62 on the display unit 56D.

[0161] The auxiliary operating device 44 receives a first command sent by the transmission operating device 64. The auxiliary operating device 44 is configured to send the first command received from the transmission operating device 64 (which operates the transmission 62) to the auxiliary unit 42. The auxiliary operating device 44 is configured, for example, to communicate with the transmission 62 via a first communication method. The auxiliary operating device 44 sends the first transmission command received from the auxiliary unit 42 to the transmission 62.

[0162] The auxiliary unit 42 receives a first instruction from the auxiliary operating device 44 via wired communication. The auxiliary unit 42 is configured to send a first gear shifting instruction to the auxiliary operating device 44 based on the first instruction received from the auxiliary operating device 44. The auxiliary control unit 48 is configured to cause the auxiliary operating device 44 to send a first gear shifting instruction to the gear shifting device 62 based on the receipt of the first instruction from the auxiliary operating device 44. The first gear shifting instruction may be sent from the auxiliary operating device 44, for example, at a predetermined time after the auxiliary operating device 44 receives the first instruction.

[0163] In the control system 60, the transmission 62 is configured to perform a gear shifting operation according to a predetermined period. The auxiliary control unit 48 is configured, for example, to calculate the predetermined period based on the output of the detection unit 52. The predetermined period is, for example, a period based on at least one of the cadence of the manual transmission 10 and the crank angle of the crank 18 of the manual transmission 10. The predetermined period is, for example, determined based on at least one of the cadence, manual driving force, the rotation angle of the crank 18, the rotation angle of the second rotating body 36, and the gear. The predetermined period can also be a constant time. A constant time is, for example, set by the transmission 62 to a sufficient time until the change in gear ratio is completed.

[0164] The predetermined period is set, for example, based on the period during which the gear ratio can be appropriately changed by the transmission device 62. The predetermined period includes, for example, a period during which the manual driving force is reduced. The predetermined period is calculated, for example, by the auxiliary unit 42. The transmission device 62 is configured to perform a gear shifting operation based on the predetermined period. The transmission device 62 determines, for example, the start timing of starting the gear shifting operation based on the predetermined period. The transmission device 62 determines, for example, the period during which the actuator 68 is actuated based on the predetermined period. The auxiliary unit 42 is configured to reduce the auxiliary force based on the predetermined period. The auxiliary unit 42 reduces the auxiliary force, for example, based on the predetermined period, during the period when the transmission device 62 performs the gear shifting operation.

[0165] The predetermined period corresponds to a period less than or equal to a predetermined percentage of the maximum value of the human-driven force. The auxiliary control unit 48 is configured, for example, to acquire the maximum value of the human-driven force every predetermined period based on the detection result of the human-driven force detection unit 52C. The predetermined percentage is, for example, 10% or more and 90% or less. The predetermined percentage is, for example, 60% or more and 80% or less. The human-driven force is at its minimum value, for example, when the first crank arm 22A or the second crank arm 22B is at top dead center or bottom dead center. The human-driven force is at its maximum value, for example, when the first crank arm 22A or the second crank arm 22B is at a position corresponding to a peak point between top dead center and bottom dead center. When the first crank arm 22A rotates in the first direction, the first crank arm 22A passes from the peak point through the top dead center, through the next peak point, and through the bottom dead center, thereby returning to the initial peak point.

[0166] The predetermined period is, for example, the time point during which the rotation angle of crank 18 becomes the angle corresponding to top dead center or bottom dead center. The predetermined period is, for example, the time point during which the first crank arm 22A or the second crank arm 22B is at top dead center or bottom dead center. Hereinafter, the predetermined period will be explained based on the time point when the first crank arm 22A is at top dead center. The predetermined period can be based on the time point when the first crank arm 22A is at bottom dead center, or it can be based on the time point when the second crank arm 22B is at top dead center, or it can be based on the time point when the second crank arm 22B is at bottom dead center.

[0167] When the second rotating body 36 includes a speed-shifting amplification region, the predetermined period can also be determined based on the speed-shifting amplification region. In the case where the predetermined period is determined based on the speed-shifting amplification region, the predetermined period may be determined, for example, based on the rotation angle of the second rotating body 36.

[0168] When a predetermined shift period is determined based on the gear shift, for example, the auxiliary storage unit 50 stores information related to the shift period required for each gear and when changing from one gear to another. The information related to the shift period includes, for example, a table storing the gear before the shift and the shift period corresponding to the gear after the shift. The shift period is set, for example, based on a predetermined rotation angle and the amount of chain winding onto the sprocket corresponding to the changed gear. The predetermined rotation angle can be a constant value or can be varied depending on the size of the sprocket. The amount of chain winding includes the length of the portion where the sprocket engages with the transmission body 38.

[0169] The auxiliary control unit 48, for example, determines a predetermined period upon receiving a first instruction. The auxiliary control unit 48 generates a first gear shift instruction based on the predetermined period. The first gear shift instruction includes, for example, information related to the gear shift start timing and the operating time of the actuator 68. The auxiliary control unit 48 generates the first gear shift instruction based on the predetermined period. Upon receiving the first gear shift instruction, the gear shift control unit 70 initiates the gear shift operation based on the information contained in the first gear shift instruction related to the gear shift start timing and the operating time of the actuator 68.

[0170] The auxiliary unit 42 is configured, for example, to reduce the auxiliary force according to a first command. The auxiliary unit 42 is configured to reduce the auxiliary force based on the shift start timing determined by the first command and the operating time of the actuator 68. The predetermined period corresponds, for example, to the period during which the auxiliary force of the auxiliary unit 42 is reduced according to the first command. The auxiliary control unit 48 calculates the reduction period of the auxiliary force based, for example, on the shift start timing and the operating time of the actuator 68. The start timing of the reduction period is, for example, set before the shift start timing. The start timing of the reduction period can also be set after the shift start timing. The end timing of the reduction period is, for example, set after the actuator 68 has completed its operation. The end timing of the reduction period can also be set before the actuator 68 has completed its operation. The end timing of the reduction period can also be when the change in the shift ratio is detected.

[0171] The auxiliary unit 42 is configured, for example, not to provide assistance during the lowering period. The auxiliary unit 42 sets the assistance force to zero, for example, during the lowering period.

[0172] The auxiliary control unit 48 can also be configured to control the motor 46 at an auxiliary level that becomes the shift assist level during deceleration. The shift assist level is set to a level lower than a predetermined auxiliary level. The shift assist level can also be changed according to the shifting operation. For example, the greater the difference between the shift ratio before and after the shift, the smaller the shift assist level is set.

[0173] The auxiliary control unit 48 can, for example, change the transmission assist level based on the amount of manual driving force. The auxiliary control unit 48 can change the transmission assist level, for example, by adjusting the level of manual driving force to a lower level. The greater the manual driving force, the more significantly the control system 60 reduces the assist force of the auxiliary unit 42, so that the user is less likely to perceive the reduction in assist force.

[0174] The auxiliary control unit 48 can, for example, change the gear shift assist level based on the pitch angle of the manually driven vehicle 10. The auxiliary control unit 48 can change the gear shift assist level, for example, in a manner that the greater the pitch angle of the manually driven vehicle 10, the greater the gear shift assist level. By changing the gear shift assist level based on the pitch angle of the manually driven vehicle 10, the assist force of the auxiliary unit 42 is maintained when the manually driven vehicle 10 is traveling uphill, and the transmission device 62 can perform gear shifting operations.

[0175] When the assist level includes an assist ratio, the shift assist level includes a shift assist ratio. The assist control unit 48 is configured, for example, to control the motor 46 such that the assist ratio becomes the shift assist ratio during deceleration. The shift assist ratio can also be changed according to the shifting operation. For example, the greater the difference between the shift ratio before and after the shift, the smaller the shift assist ratio is set.

[0176] When the assist level includes the maximum assist value, the shift assist level includes the shift assist maximum value. The assist control unit 48 is configured, for example, to control the motor 46 during deceleration in a manner that makes the maximum assist value below the shift assist maximum value. The predetermined maximum assist value can also be changed according to the shifting operation. For example, the greater the difference between the shift ratio before and after the shift, the smaller the shift assist maximum value is set.

[0177] The transmission device 62 is configured to control the motor 46 at a predetermined auxiliary level once the deceleration period ends. Alternatively, the transmission device 62 can be configured to change the auxiliary level from the transmission auxiliary level to a predetermined auxiliary level prior to the transmission auxiliary level once the deceleration period ends, after a predetermined increase period. By changing the auxiliary level over a predetermined increase period, the user can less easily perceive the change in the auxiliary force of the auxiliary unit 42.

[0178] The auxiliary unit 42 can also be configured such that if the auxiliary force is below a predetermined auxiliary force during a predetermined period, the auxiliary force will not be reduced during that period. The predetermined auxiliary force is, for example, set to a value that does not affect the shifting operation of the transmission device 62.

[0179] The transmission device 62 can also be configured such that, when a transmission operation is performed based on a second transmission command, the transmission control unit 70 calculates a predetermined period. The transmission control unit 70 can also be configured to calculate the predetermined period based on the output of the detection unit 52. When the transmission operation is performed based on a second transmission command, the transmission device 62 determines the transmission start timing and the actuator 68's operating time based on the predetermined period. The transmission device 62 can also be configured such that, when a transmission operation is performed based on a second transmission command, the transmission control unit 70 sends the predetermined period calculated by the transmission device 70 to the auxiliary unit 42.

[0180] Reference Figure 5 The processing of the transmission operation control unit 78 controlling the transmission operation device 64 in the control system 60 will be described. For example, when power is supplied to the transmission operation control unit 78, the transmission operation control unit 78 begins processing and transfers to... Figure 5 Step S21 of the flowchart shown. If Figure 5 Once the flowchart ends, the speed change operation control unit 78 will, for example, repeatedly perform the processing from step S21 after a predetermined cycle until the power supply stops.

[0181] In step S21, the shift operation control unit 78 determines whether the shift operation unit 82 has been operated. If the shift operation unit 82 has been operated, the shift operation control unit 78 proceeds to step S22. If the shift operation unit 82 has not been operated, the shift operation control unit 78 terminates the process. Figure 5 The processing.

[0182] In step S22, the shift operation control unit 78 determines whether the communication control state is a first communication control state. If the shift operation control unit 78 is configured to receive the current communication control state from the shift control unit 70, the shift operation control unit 78 determines the communication control state, for example, based on the current communication control state received from the shift control unit 70. If the operation input unit 76 is provided in at least one of a personal computer, a tablet computer, and a smartphone, the shift operation control unit 78 may also be configured to receive the current communication control state from the operation input unit 76. If the shift operation unit 82 includes a switching operation unit, the shift operation control unit 78 determines the communication control state, for example, based on the operation input to the switching operation unit. If the communication control state is a first communication control state, the shift operation control unit 78 proceeds to step S23. In step S23, the shift operation control unit 78 sends a first command via a first communication method, and the process ends. Figure 5 The transmission operation control unit 78 causes the transmission operation communication unit 84 to send a first command to the auxiliary operation device 44 via a first communication method.

[0183] If the communication control state is not the first communication control state in step S22, the transmission operation control unit 78 proceeds to step S24. In step S24, the transmission operation control unit 78 sends a second transmission command via the second communication method, and the process ends. Figure 5 The transmission operation control unit 78 causes the transmission operation communication unit 84 to send a second transmission command to the transmission device 62 via a second communication method.

[0184] Reference Figure 6 The processing of the auxiliary operation control unit 54 controlling the auxiliary operation device 44 will be explained. For example, if power is supplied to the auxiliary operation control unit 54, the auxiliary operation control unit 54 begins processing and transfers to... Figure 6 Step S31 of the flowchart shown. If Figure 6 Once the flowchart ends, the auxiliary operation control unit 54 will, for example, repeatedly perform the processing starting from step S31 after a predetermined cycle until the power supply stops.

[0185] In step S31, the auxiliary operation control unit 54 determines whether the first instruction has been received. If the auxiliary operation communication unit 58 receives the first instruction, the auxiliary operation control unit 54 determines that the first instruction has been received. If the first instruction has been received, the auxiliary operation control unit 54 proceeds to step S32. In step S32, the auxiliary operation control unit 54 sends the first instruction to the auxiliary unit 42, and the process ends. Figure 6 The processing.

[0186] If the auxiliary operation control unit 54 does not receive the first command in step S31, it proceeds to step S33. In step S33, the auxiliary operation control unit 54 determines whether the first gear shift command has been received. If the first gear shift command has been received, the auxiliary operation control unit 54 proceeds to step S34. If the auxiliary operation control unit 54 does not receive the first gear shift command in step S33, it terminates the operation. Figure 6 The processing.

[0187] In step S34, the auxiliary operation control unit 54 sends a first speed change command via a first communication method, thus ending the process. Figure 6 The auxiliary operation control unit 54 sends a first speed change command from the auxiliary operation communication unit 58 via a first communication method in step S34.

[0188] Reference Figure 7 The processing of the auxiliary control unit 48 by the auxiliary control unit 42 will be explained. For example, when power is supplied to the auxiliary control unit 48, the auxiliary control unit 48 begins processing and transfers to the auxiliary control unit 42. Figure 7 Step S41 in the flowchart shown. Auxiliary control unit 48 in... Figure 7 At the end of the flowchart, for example before the power supply stops, the process starting from step S41 is repeated after a predetermined period.

[0189] In step S41, the auxiliary control unit 48 determines whether a first command has been received. If the auxiliary control unit 48 receives a first command from the auxiliary operation device 44, it determines that the first command has been received. If the first command has been received, the auxiliary control unit 48 proceeds to step S42. If the auxiliary control unit 48 has not received a first command in step S41, it terminates the process. Figure 7 The processing.

[0190] In step S42, the auxiliary control unit 48 calculates a predetermined period based on the first command and proceeds to step S43. In step S43, the auxiliary control unit 48 sends the first gear shift command to the auxiliary operating device 44 and proceeds to step S44.

[0191] In step S44, the auxiliary control unit 48 determines whether to begin reducing the auxiliary force. For example, if the current time is the start timing of the reduction period, the auxiliary control unit 48 determines that the reduction of the auxiliary force should begin. If the reduction of the auxiliary force does not begin, the auxiliary control unit 48 repeats step S44 until it determines that the reduction of the auxiliary force has begun. If the reduction of the auxiliary force begins, the auxiliary control unit 48 proceeds to step S45. In step S45, the auxiliary control unit 48 reduces the auxiliary force and proceeds to step S46.

[0192] In step S46, the auxiliary control unit 48 determines whether to end the reduction of the auxiliary force. For example, if the current time is the end time of the reduction period, the auxiliary control unit 48 determines to end the reduction of the auxiliary force. If the reduction of the auxiliary force is not to end, the auxiliary control unit 48 repeats step S46 until it determines that the reduction of the auxiliary force has ended. If the reduction of the auxiliary force has ended, the auxiliary control unit 48 proceeds to step S47. In step S47, the auxiliary control unit 48 increases the auxiliary force, ending the process. Figure 7 The auxiliary control unit 48, for example, in step S47, changes the auxiliary force of the auxiliary unit 42 to the auxiliary force before the processing in step S45.

[0193] Reference Figure 8 The processing of the transmission control unit 70 controlling the transmission device 62 in the control system 60 will be described. For example, when power is supplied to the transmission control unit 70, the transmission control unit 70 begins processing and transfers to... Figure 8 Step S51 of the flowchart shown. If Figure 8 Once the flowchart ends, the transmission control unit 70 will, for example, repeatedly perform the processing from step S51 after a predetermined cycle until the power supply stops.

[0194] In step S51, the transmission control unit 70 determines whether the communication control state is the first communication control state. If the communication control state is the first communication control state, the transmission control unit 70 proceeds to step S52.

[0195] In step S52, the transmission control unit 70 determines whether a first transmission command has been received. If the first transmission command has been received, the transmission control unit 70 proceeds to step S53. If the first transmission command has not been received, the transmission control unit 70 terminates the process. Figure 7 The processing. In step S53, the transmission control unit 70 performs a transmission operation based on the first transmission command, and ends the process. Figure 7 The processing.

[0196] If the communication control state is not the first communication control state in step S51, the transmission control unit 70 proceeds to step S54. In step S54, the transmission control unit 70 determines whether a second transmission command has been received. If a second transmission command has been received, the transmission control unit 70 proceeds to step S55. If no second transmission command has been received, the transmission control unit 70 terminates the process. Figure 7 The processing. In step S55, the transmission control unit 70 performs a transmission operation based on the second transmission command, and ends the process. Figure 7 The processing.

[0197] In the control system 60, the auxiliary unit 42 generates a first gear shift command, so the gear shifting device 62 can appropriately perform a gear shifting operation in a manner corresponding to the period of reduction of the auxiliary force of the auxiliary unit 42. According to the control system 60, even when the gear shifting operation of the gear shifting device 62 and the control of the auxiliary force of the auxiliary unit 42 are performed independently, the gear shifting device 62 can still perform a gear shifting operation during the period of reduction of the auxiliary force of the auxiliary unit 42.

[0198] In the control system 60, the auxiliary operating device 44 relays the first command output by the transmission operating device 64 to the auxiliary unit 42. Since the auxiliary operating device 44 is built into the jacking pipe 16B, the distance from the transmission device 62 to the auxiliary operating device 44 is shorter than the distance from the transmission operating device 64 to the auxiliary unit 42. By relaying the communication of the first command through the auxiliary unit 42, the reliability of communication between the transmission operating device 64 and the auxiliary unit 42 is improved. Therefore, the transmission device 62 can perform transmission operations more reliably based on the actions of the auxiliary unit 42.

[0199] The transmission device 62 can receive transmission commands via both a first communication method and a second communication method. The transmission device 62 can switch communication control states to select either the first or second communication method. Therefore, even if the transmission device 62 does not communicate with the auxiliary unit 42 and the auxiliary operating device 44, it can still perform transmission actions based on the second transmission command. Thus, the transmission device 62 contributes to availability.

[0200] <Example of Change>

[0201] The description of the embodiments is an illustration of the possible methods of the control system and transmission device for manually driven vehicles disclosed herein, and is not intended to limit the methods. The control system and transmission device for manually driven vehicles disclosed herein can be implemented in, for example, variations of the embodiments shown below, as well as combinations of at least two non-contradictory variations. In the following variations, for parts common to the embodiments, the same reference numerals are used as in the embodiments, and their descriptions are omitted.

[0202] At least one of the transmission device 62 and the transmission operation device 64 may also omit the configuration for wireless communication based on the second communication method. For example, the transmission device 62 includes a first communication unit 66A but does not include a second communication unit 66B. The transmission device 62 is configured, for example, to wirelessly communicate with the auxiliary operation device 44 via the first communication method, and omits the configuration for wireless communication based on the second communication method. In this modified example, for example, the second communication method is not implemented... Figure 4 The processing. In this modified example, for example, omitting... Figure 5The processing of steps S22 and S24 and Figure 8 The processing of steps S51, S54 and S55.

[0203] • The transmission control unit 70 can also control the communication unit 66 in a manner that allows the second communication unit 66B to receive the second transmission command when it is in the first communication control state. The transmission control unit 70 can also control the actuator 68 in a manner that does not perform a transmission operation according to the second transmission command even if it receives the second transmission command when it is in the first communication control state.

[0204] • The transmission control unit 70 can also control the communication unit 66 in a manner that allows the first communication unit 66A to receive the first transmission command when in the second communication control state. The transmission control unit 70 can also control the actuator 68 in a manner that, even if the first transmission command is received, it does not perform a transmission operation according to the first transmission command when in the second communication control state.

[0205] The auxiliary unit 42 may also have a current sensor that detects the current flowing through the inverter circuit. The current sensor may be connected to the auxiliary control unit 48 via wired or wireless means, for example, in a communicative manner. The auxiliary control unit 48 may also calculate a predetermined period based on the current detected by the current sensor.

[0206] • The second communication unit 66B can also be integrally constructed with the first communication unit 66A, provided that the second communication method is different from the first communication method. For example, the communication unit 66 in this modified example has an antenna capable of switching frequency bands between the first and second communication methods.

[0207] • The second communication method can also be wired communication. Examples of the second communication method are power line communication (PLC) or UART.

[0208] The first shift command may also not include information related to the shift start timing. For example, the auxiliary control unit 48 is configured to send the first shift command to the shifting device 62 via the shifting operation device 64 when the current time becomes the shift start timing. In this modified example, the shifting device 62 starts shifting upon receiving the first shift command. The auxiliary control unit 48 may also be configured to immediately send the first shift command to the shifting device 62 via the shifting operation device 64 upon receiving the first command. When the auxiliary control unit 48 is configured to immediately send the first shift command to the shifting device 62 via the shifting operation device 64 upon receiving the first command, the auxiliary control unit 48 may also immediately begin reducing the auxiliary force upon receiving the first command.

[0209] • The first gear shift command may also not include information related to the operating time of the actuator 68.
