A motor 160 driven by the electric power supplied from the motor drive circuit 120, and a power transmission mechanism (not shown) for transmitting the auxiliary driving force generated by the driving of the motor 160 to the chain 29. It is out. In the present embodiment, a so-called center mount type bicycle with a motor that mounts the motor 160 near the bottom bracket and transmits the auxiliary driving force of the motor 160 to the chain 29 is illustrated, but the driving method is particularly limited. The present invention can be applied to a system in which a hub motor is incorporated in the front wheel 21 or the rear wheel 22 instead of the above.

  Electric power for driving the motor 160 is supplied from a battery 110 that is detachably provided along the seat tube 14. The battery 110 is composed of, for example, a lithium ion secondary battery, and can be repeatedly used by charging.

  A stay 31 for supporting the basket 30 is connected to the front end portion of the front fork 11. A light 170 is attached to the stay 31.

  FIG. 2 is a block diagram showing a configuration of an electric system of the electric bicycle 1 according to the embodiment of the present invention. The control unit 100 comprehensively controls driving of the light 170 and the motor 160 based on an operation input to the operation / display unit 180 by the user. For example, a single semiconductor chip includes a CPU (arithmetic processing unit), a memory In addition, an LSI (Large Scale Integration) in which a computer system including an input / output circuit, a timer circuit, and the like is integrated is configured. Note that the control unit 100 operates with electric power supplied from the battery 110.

  Based on the detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210, the control unit 100 derives an assist amount suitable for the driving situation by calculation. For example, when the vehicle speed is low and the input torque (stepping force) is large, it is estimated that the vehicle is in a state immediately after starting or a state where the vehicle is traveling uphill. Deriving a large assist amount. The control unit 100 changes the assist ratio in accordance with the assist mode selected by the input operation on the mode selection button 185 (see FIGS. 4B and 5) of the operation / display unit 180. In the bicycle 1 with an electric motor according to the present embodiment, three assist modes (eco, standard, power) having different assist ratios are determined in advance, and one of these is pressed by pressing the mode selection button 185. Can be selected. The control unit 100 supplies a control signal (torque command value) indicating the derived assist amount to the motor drive circuit 120.

  For example, when the vehicle speed of the host vehicle detected by the vehicle speed sensor 210 is equal to or higher than a predetermined value and the torque (stepping force) detected by the torque sensor 200 is smaller than the predetermined value, the control unit 100 The operation shifts to a regenerative charging mode in which the battery 110 is charged by the electric power generated with the rotation of 160. The control unit 100 supplies a power signal from the battery 110 to the motor 160 by supplying a control signal to the motor drive circuit 120 to obtain an auxiliary driving force by the motor 160, and uses the power generated by the motor 160. Switching to the regenerative charging mode for charging the battery 110.

  The conditions for shifting to the regenerative charging mode are not limited to those described above. For example, the control unit 100 may shift to the regenerative charging mode when a brake operation is detected. In this case, a brake sensor for detecting a brake operation is provided, and the control unit 100 shifts to the regenerative charging mode based on a detection signal from the brake sensor. Moreover, the control part 100 may transfer to regenerative charge mode, when the inertial driving | running | working to which the treading force is not applied is detected.

  The motor drive circuit 120 is connected to the battery 110 via the power supply line L1. In the power running mode, the motor drive circuit 120 extracts drive power corresponding to the assist amount (torque command value) derived by the control unit 100 from the battery 110 and supplies it to the motor 160, and in the regenerative charge mode, the motor 160 The battery 110 is charged by supplying the generated power to the battery 110.

  FIG. 3 is a diagram showing in detail the connection relationship between battery 110, motor drive circuit 120, and motor 160. The motor drive circuit 120 includes an inverter circuit 121 including transistors T1 to T6 and an inverter control circuit 122 that generates a gate signal for individually turning on and off the transistors T1 to T6 constituting the inverter circuit 121. Further, the motor drive circuit 120 includes a transistor T7 connected to the inverter circuit 121. The transistor T7 is also turned on / off according to the gate signal supplied from the inverter control circuit 122. Each of the transistors T1 to T6 includes an n-channel MOSFET having a diode having a cathode connected to the drain side and an anode connected to the source side. That is, the transistors T1 to T6 can pass a current in the reverse direction via the diode even in the off state. On the other hand, the transistor T7 is configured by a p-channel MOSFET having an anode connected to the drain side and a cathode connected to the source side. That is, the transistor T7 can flow a current in the reverse direction via the diode even in the off state.

  In the present embodiment, the motor 160 is constituted by an inner rotor type brushless motor, and includes a rotor including a permanent magnet, a stator having a motor winding C, and three Hall elements H for detecting the rotational position of the rotor. , Including.

  Connection points u, v, transistors T1, T3, T5 connected to the positive side (high side) of the battery 110 and transistors T2, T4, T6 connected to the negative side (low side) of the battery 110, w is connected to each of the three motor windings C. The inverter control circuit 122 detects the angular position of the rotor based on the detection signals output from the three hall elements H, and turns on the transistors T1 to T6 in a predetermined order according to the detected angular position. Thereby, the direction of the current flowing through the motor winding C is sequentially switched, and the rotor rotates.

  The inverter control circuit 122 performs torque control of the motor 160 by performing PWM control for adjusting the on-duty of the transistors T1 to T6 in accordance with a control signal indicating the assist amount (torque target value) supplied from the control unit 100. . Further, the inverter control circuit 122 cuts off the power supply from the motor 160 to the battery 110 by turning off the transistor T7 in the powering mode. Note that the current from the battery 110 is supplied to the motor 160 via the diode of the transistor T7.

  On the other hand, in the regenerative charge mode, the inverter control circuit 122 keeps all the high-side transistors T1, T3, and T5 in the off state and turns on and off the low-side transistors T2, T4, and T6 at the same timing. PWM control is performed and the transistor T7 is turned on. During a period in which the low-side transistors T2, T4, and T6 are in an on state, a short-circuit current flows through the motor winding C and energy is stored in the motor winding C, thereby generating a braking force in the motor 160. . When the low-side transistors T2, T4, and T6 are turned off from this state, an induced voltage is generated in the motor winding C, and a regenerative current is supplied to the battery 110 via the diodes of the transistors T2, T4, and T6 and the transistor T7. This causes the battery 110 to be charged.

  The write drive circuit 130 is connected to the battery 110 via the power supply line L2. Based on the control signal supplied from the control unit 100, the light driving circuit 130 takes out the driving power from the battery 110 and supplies it to the light 170 to turn on the light 170. The control unit 100 controls turning on and off of the light 170 by controlling the light driving circuit 130 based on an operation input to the operation / display unit 180. In addition, when the automatic lighting mode is selected based on an input operation on the operation / display unit 180, the control unit 100 turns on and off the light 170 based on the illuminance detection signal supplied from the illuminance sensor 220. Control. Note that the automatic lighting mode is a mode in which the light 170 is automatically turned on and off according to the ambient brightness.

  The illuminance sensor 220 includes a photoelectric conversion element such as a photodiode or a phototransistor and a photoconductive element such as a Cds cell, and has a signal level corresponding to the brightness detected by detecting ambient brightness. Output illuminance detection signal. The illuminance sensor 220 is arranged so that light around the host vehicle is irradiated on the light detection surface.

  The control unit 100 is connected to the operation / display unit 180 via a signal line, and controls the motor drive circuit 120 and the light drive circuit 130 in accordance with an operation input to the operation / display unit 180 by the user. Further, the control unit 100 displays the remaining battery level on the display surface 180A (see FIG. 4A) of the operation / display unit 180 based on the voltage detection signal from the voltage sensor 230 that detects the voltage level of the battery 110. Let

  4A is a plan view showing an example of the configuration of the display surface 180A of the operation / display unit 180, and FIG. 4B is a plan view showing an example of the configuration of the operation surface 180B of the operation / display unit 180. FIG. 5 is a block diagram showing the configuration of the electrical system of the operation / display unit 180.

  In the present embodiment, the operation / display unit 180 has a substantially rectangular parallelepiped shape, and the display surface 180A and the operation surface 180B constitute two adjacent surfaces of the rectangular parallelepiped. In the present embodiment, the operation / display unit 180 is installed on the handle 24 so that the display surface 180A faces upward and the operation surface 180B faces the user.

  Various display units 181 to 184 for displaying the state of the host vehicle are provided on the display surface 180 </ b> A of the operation / display unit 180. Further, on the operation surface 180B of the operation / display unit 180, a mode selection button 185 for the user to select setting of the assist ratio by the motor 160, and a light button 186 for the user to select whether the light 170 is turned on or off. And are provided.

  The battery remaining amount display unit 181 is a display unit that displays the current voltage level of the battery 110. As shown in FIG. 4A, the battery remaining amount display unit 181 includes five light emitting units for displaying the current battery voltage level in five stages. When the display control unit 187 receives information indicating the voltage level of the battery 110 from the control unit 100, the display control unit 187 turns on the light emitting units by the number corresponding to the voltage level.

  The assist mode display unit 182 is a display unit that displays the assist mode selected by operating the mode selection button 185. In the present embodiment, any one of three assist modes (eco, standard, power) having different assist ratios can be selected by pressing the mode selection button 185. It is also possible to select an assist-off mode in which the assist by the motor 160 (generation of auxiliary driving force) is stopped by pressing the mode selection button 185. Each time the mode selection button 185 is pressed, the three assist modes and the assist-off mode are sequentially selected. When the display control unit 187 receives information indicating the currently selected assist mode from the control unit 100, the display control unit 187 turns on the light emitting unit corresponding to the selected assist mode.

  The light lighting display unit 183 is a display unit indicating that the light 170 is turned on. The light lighting unit 183 includes a light emitting unit that is turned on when the light 170 is turned on and turned off when the light 170 is turned off. When the display control unit 187 receives information indicating that the light 170 is turned on from the control unit 100, the display control unit 187 turns on the light emitting unit.

  The power saving mode display unit 184 is a display unit indicating that the host vehicle is currently in the power saving mode. The power saving mode display unit 184 includes a light emitting unit that is turned on in the power saving mode. For example, when the control unit 100 determines that the host vehicle is continuously stopped for a predetermined period (for example, 3 minutes) based on detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210, the control unit 100 shifts to the power saving mode. To do. When the display control unit 187 receives information indicating the transition to the power saving mode from the control unit 100, the display control unit 187 turns on the light emitting unit of the power saving mode display unit 184 and also displays the remaining battery level display unit 181, the assist mode display unit 182, and the light. The light emitting unit of the lighting display unit 183 is turned off. In addition, when the control unit 100 shifts to the power saving mode, the control unit 100 controls the light driving circuit 130 so that the light 170 is maintained in the off state. When the control unit 100 returns from the power saving mode, the control unit 100 controls the light driving circuit 130 to drive the light 170 in a state before the transition to the power saving mode. The condition for shifting to the power saving mode is not limited to the above case. For example, in addition to the above case, when the operation input to the light button 186 and the mode selection button 185 is not performed for a predetermined period, the brake is applied. When the operation is not performed for a predetermined period, the mode may be shifted to the power saving mode. The electric system of the operation / display unit 180 is operated by electric power supplied from the battery 110. By shifting to the power saving mode described above, the number of lighting of the light emitting units is reduced, so that the consumption of the battery 110 can be reduced.

  When the light button 186 and the mode selection button 185 are pressed, the display control unit 187 supplies a control signal indicating that these buttons have been pressed to the control unit 100. The control unit 100 that has received such a control signal performs the following control.

  FIG. 6 is a diagram showing a state transition of the electric bicycle 1 according to the first embodiment of the present invention, which is switched by operating the mode selection button 185 and the light button 186.

(First state)
The first state corresponds to a so-called power-off state, and the control unit 100 stops functioning in the first state. That is, power is not supplied to a CPU (arithmetic processing unit) constituting the control unit 100, and the function of the CPU is stopped. Further, in the first state, the motor drive circuit 120 and the light drive circuit 130 are in an off state, so that power is not supplied from the battery 110 to the motor 160 and the light 170. That is, in the first state, assist (generation of auxiliary driving force) and regenerative charging by the motor 160 are stopped, and the light 170 is turned off.

(Second state)
When the mode selection button 185 or the light button 186 is pressed in the first state, the CPU configuring the control unit 100 is activated and shifts to the second state. In the second state, the control unit 100 drives the light 170 in the automatic lighting mode. That is, when the signal level of the illuminance detection signal supplied from the illuminance sensor 220 is equal to or lower than a predetermined threshold (that is, when the surrounding brightness is darker than the predetermined brightness), the control unit 100 turns the light 170 on. When a control signal is supplied to the light drive circuit 130 to turn on and the signal level of the illuminance detection signal supplied from the illuminance sensor 220 is higher than a predetermined threshold (that is, when the surrounding brightness is brighter than the predetermined brightness) ), A control signal is supplied to the write drive circuit 130 to turn off the light 170. Thus, in the second state, the light 170 is turned on or off according to the ambient brightness. When the light 170 is turned on, the light emitting unit of the light lighting display unit 183 of the operation / display unit 180 is in a lighting state, so that the user can recognize that the light 170 is turned on or off.

  Further, in the second state, assist enable / stop switching and assist mode switching by the motor 160 can be performed by pressing the mode selection button 185. That is, the control unit 100 switches the assist mode in the order of “power”, “standard”, and “eco” every time the mode selection button 185 is pressed in the second state. In addition, when the mode selection button 185 is pressed while “eco” is selected as the assist mode, the control unit 100 stops assist (generation of auxiliary driving force) by the motor 160. In addition, when the mode selection button 185 is pressed in the assist stop state, the control unit 100 validates the assist in the state where the assist mode is “power”. That is, every time the mode selection button 185 is pressed in the second state, the control unit 100 sets the mode of assistance by the motor 160 to “power”, “standard”, “eco”, “assist stop”,. Switch in order. Note that the switching order of these four modes can be changed as appropriate. Since the selected assist mode is displayed on the assist mode display unit 182 of the operation / display unit 180, the user can recognize which assist mode is currently selected.

  When the assist is enabled, the control unit 100 calculates an assist amount suitable for the driving situation based on detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210, and calculates the calculated assist amount. A corresponding control signal (torque command value) is supplied to the motor drive circuit 120. Note that the control unit 100 stores the last assist mode selected by the user, and when shifting from the first state to the second state, the assist ratio according to the stored assist mode is obtained. Thus, a control signal (torque command value) is generated and supplied to the motor drive circuit 120. For example, after the standard mode is selected, when the state shifts to the first state (that is, the power is turned off) and then shifts to the second state, the motor 160 in the second state Driven in mode.

  In the second state, regenerative charging by the motor 160 is enabled. That is, in the second state, the control unit 100 supplies the motor drive circuit 120 with a control signal to be shifted to the regenerative charging mode when a predetermined condition for shifting to the regenerative charging mode is satisfied. As a result, the high-side transistors T1, T3, and T5 constituting the motor drive circuit 120 are all maintained in the off state, and the low-side transistors T2, T4, and T6 are PWM-controlled so that they are turned on and off at the same timing. And the transistor T7 is turned on. Thereby, the battery 110 is charged with the electric power generated by the rotation of the motor 160.

(Third state)
In the third state, as in the second state, it is possible to switch assist assist / stop and assist mode switching by the motor 160 using the mode selection button 185. That is, the control unit 100 switches the assist mode in the order of “power”, “standard”, and “eco” every time the mode selection button 185 is pressed in the third state. In addition, when the mode selection button 185 is pressed while “eco” is selected as the assist mode, the control unit 100 stops assist (generation of auxiliary driving force) by the motor 160. In addition, when the mode selection button 185 is pressed in the assist stop state, the control unit 100 validates the assist in the state where the assist mode is “power”. That is, every time the mode selection button 185 is pressed in the second state, the control unit 100 changes the assist state by the motor 160 to “power”, “standard”, “eco”, “assist stop”,. Switch in order. Note that the switching order of these four states can be changed as appropriate.

  In the third state, the control unit 100 forcibly turns on or off the light 170. That is, the control unit 100 switches on / off the light 170 in accordance with the operation of the light button 186 by the user regardless of the ambient brightness detected by the illuminance sensor 220. For example, when the light 170 is automatically turned on in the second state, when the light button 186 is pressed, the control unit 100 shifts to the third state, and the control unit 100 performs the light so that the light 170 is turned off. The drive circuit 130 is controlled. Thereafter, each time the light button 186 is pressed in the third state, the light 170 is turned on and off. In the third state, the point that the regenerative charging by the motor 160 is enabled is the same as in the second state.

  In the present embodiment, in the second state and the third state, the light button 186 or the mode selection button 185 is continuously pressed for a predetermined period t1 (for example, 2 seconds), whereby the first state ( That is, the power supply is turned off. In addition, after the light 170 is automatically turned on according to the ambient brightness, the light 170 is forcibly turned on or turned off, and then the first mode (power supply is turned on). It is possible to shift to the second state after shifting to the off state.

  Further, as described above, for example, the control unit 100 determines that the host vehicle is continuously stopped for a predetermined period (for example, 3 minutes) based on detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210. If this happens, it will switch to the power saving mode. When the control unit 100 shifts to the power saving mode, the control unit 100 supplies a control signal to the display control unit of the operation / display unit 180 to 187. When the display control unit 187 receives the control signal from the control unit 100, the display control unit 187 turns on the light emitting unit of the power saving mode display unit 184 and emits light from the remaining battery level display unit 181, the assist mode display unit 182, and the light lighting display unit 183. Turn off the light. In addition, when the control unit 100 shifts to the power saving mode, the control unit 100 controls the light driving circuit 130 so that the light 170 is maintained in the off state.

  When the control unit 100 determines that the state in which the host vehicle is stopped after shifting to the power saving mode continues for a predetermined period (for example, 2 minutes), the control unit 100 shifts to the first state (that is, the power-off state). . As a result, the control unit 100, the motor drive circuit 120, and the light drive circuit 130 are turned off, and all the light emitting units constituting the display units 181 to 184 in the operation / display unit 180 are turned off.

  FIG. 7 is a flowchart according to the first embodiment of the present invention showing the flow of processing when the control unit 100 transitions to the first to third states based on an input operation on the operation / display unit 180. It is.

  The control unit 100 is activated when the mode selection button 185 or the light button 186 is pressed in the first state corresponding to the power-off state (step S1), and in step S2, the mode selection button 185 or the light button 186 is activated. It is determined whether or not the button has been pressed. When the mode selection button 185 or the light button 186 is pressed in step S2, the control unit 100 shifts the process to step S3 (that is, shifts to the second state).

  The control unit 100 shifts to the second state in step S3, and determines whether or not the light button 186 is pressed in step S4. When the control unit 100 determines that the light button 186 is pressed in step S4, the control unit 100 shifts the process to step S6 (that is, shifts to the third state), and the light button 186 is not pressed. If it is determined, the process proceeds to step S5.

  In step S5, the control unit 100 determines whether or not a so-called long press in which the mode selection button 185 or the light button 186 is continuously pressed for a predetermined period t1 (for example, 2 seconds) has been made. If it is determined that the button has been pressed for a long time, the process proceeds to step S1 (that is, shifts to the first state), and it is determined that any one of these buttons has not been pressed for a long time. If so, the process returns to step S4.

  In step S6, the control unit 100 shifts to the third state, and in step S7, whether or not the mode selection button 185 or the light button 186 is continuously pressed for a predetermined period t1 (for example, 2 seconds) has been made. If it is determined that one of these buttons has been pressed for a long time, the process proceeds to step S1 (that is, the process proceeds to the first state).

  As is clear from the above description, in the electric bicycle 1 according to the first embodiment of the present invention, the second state where the light 170 is driven in the automatic lighting mode and the light 170 is operated by the light button 186. In the third state in which the light is turned on and off in response, the assist selection by the motor 160 can be switched by pressing the mode selection button 185 and the assist mode can be switched. That is, according to the electric bicycle 1 according to the first embodiment of the present invention, the transition from the state where the auxiliary driving force is generated by the motor to the state where the generation of the auxiliary driving force is stopped corresponds to the power-off state. This can be done without going through the first state, and this can be done by a simpler operation than before.

  In addition, according to the electric bicycle 1 according to the embodiment of the present invention, the light 170 can be turned only by pressing the mode selection button 185 or the light button 186 once from the first state corresponding to the power-off state. Since lighting and assist running are possible, the complexity of operation by the user can be eliminated.

  In addition, in the bicycle with an electric motor according to the embodiment of the present invention, only two buttons, a mode selection button 185 and a light button 186, are provided as operation units that receive user input operations. A general bicycle with an electric motor further includes a power button for starting the electric system in addition to these buttons. In the electric bicycle according to the embodiment of the present invention, the electric system is activated by pressing one of the mode selection button 185 and the light button 186, and the mode selection button 185 or the light button 186 is long pressed. As a result, the power is turned off (transition to the first state). That is, according to the electric bicycle 1 according to the embodiment of the present invention, the mode selection button 185 and the light button 186 have the function of a conventional power button. As described above, in the electric bicycle 1 according to the embodiment of the present invention, the operation / display unit 180 is made compact by eliminating the conventional power button, and the complexity of the operation by the user is eliminated. ing.

  In the above-described embodiment, the mode selection button 185 and the light button 186 are integrally provided in the operation / display unit 180. However, these buttons may be configured separately. In this case, for example, a mode selection button may be provided on the right handle, and a light button may be provided on the left handle.

  In the above-described embodiment, the case where the mode selection button 185 and the light button 186 that are button switches are provided as the operation unit that receives an input operation by the user is illustrated. You may implement | achieve with forms other than a switch, for example, forms, such as a toggle switch and a rotary switch.

  In addition to the mode selection button 185 and the light button 186, a conventional power button may be further provided. In this case, the first state in which the power is off may be shifted to the second state by pressing the power button. The transition from the second state and the third state to the first state may be performed by pressing a power button.

[Second Embodiment]
FIG. 8 is a diagram showing a state transition of the motor-equipped bicycle according to the second embodiment of the present invention that is switched by operating the mode selection button 185 and the light button 186.

(First state)
The first state corresponds to a so-called power-off state, and the control unit 100 stops functioning in the first state. That is, power is not supplied to a CPU (arithmetic processing unit) constituting the control unit 100, and the function of the CPU is stopped. Further, in the first state, the motor drive circuit 120 and the light drive circuit 130 are in an off state, so that power is not supplied from the battery 110 to the motor 160 and the light 170. That is, in the first state, assist (generation of auxiliary driving force) and regenerative charging by the motor 160 are stopped, and the light 170 is turned off.

(Second state)
When the mode selection button 185 or the light button 186 is pressed in the first state, the CPU configuring the control unit 100 is activated and shifts to the second state. In the second state, the control unit 100 drives the light 170 in the automatic lighting mode. That is, when the signal level of the illuminance detection signal supplied from the illuminance sensor 220 is equal to or lower than a predetermined threshold (that is, when the surrounding brightness is darker than the predetermined brightness), the control unit 100 turns the light 170 on. When a control signal is supplied to the light drive circuit 130 to turn on and the signal level of the illuminance detection signal supplied from the illuminance sensor 220 is higher than a predetermined threshold (that is, when the surrounding brightness is brighter than the predetermined brightness) ), A control signal is supplied to the write drive circuit 130 to turn off the light 170. Thus, in the second state, the light 170 is turned on or off according to the ambient brightness. When the light 170 is turned on, the light emitting unit of the light lighting display unit 183 of the operation / display unit 180 is in a lighting state, so that the user can recognize that the light 170 is turned on or off.

  In the second state, assist (generation of auxiliary driving force) by the motor 160 is effective. That is, in the second state, the control unit 100 calculates an assist amount suitable for the driving situation based on the detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210, and a control signal corresponding to the calculated assist amount. (Torque command value) is supplied to the motor drive circuit 120. Note that the control unit 100 stores the last assist mode selected by the user, and when shifting from the first state to the second state, the assist ratio according to the stored assist mode is obtained. Thus, a control signal (torque command value) is generated and supplied to the motor drive circuit 120. For example, after the standard mode is selected, when the state shifts to the first state (that is, the power is turned off) and then shifts to the second state, the motor 160 in the second state Driven in mode.

  Further, in the second state, when the mode selection button 185 is pressed, the assist mode can be switched. That is, the control unit 100 sequentially switches the assist mode to “power”, “standard”, “eco”, “power”,... Each time the mode selection button 185 is pressed in the second state. Note that the order of switching the assist mode by pressing the mode selection button 185 can be changed as appropriate. Since the selected assist mode is displayed on the assist mode display unit 182 of the operation / display unit 180, the user can recognize which assist mode is currently selected.

  In the second state, regenerative charging by the motor 160 is enabled. That is, in the second state, the control unit 100 supplies the motor drive circuit 120 with a control signal to be shifted to the regenerative charging mode when a predetermined condition for shifting to the regenerative charging mode is satisfied. As a result, the high-side transistors T1, T3, and T5 constituting the motor drive circuit 120 are all maintained in the off state, and the low-side transistors T2, T4, and T6 are PWM-controlled so that they are turned on and off at the same timing. And the transistor T7 is turned on. Thereby, the battery 110 is charged with the electric power generated by the rotation of the motor 160.

(Third state)
In the second state, when the mode selection button 185 is continuously pressed for a predetermined period t2 (for example, 1 second) (that is, when a long press is performed), the mode shifts to the third state. When the mode selection button 185 is pressed for a period shorter than the predetermined period t2 (for example, 1 second) recognized as a long press in the second state, the assist mode is switched. In the third state, the control unit 100 drives the light 170 in the automatic lighting mode as in the second state.

  Further, in the third state, stop of assist (generation of auxiliary driving force) by the motor 160 is maintained, while regenerative charging by the motor 160 is made effective. That is, in the third state, the control unit 100 supplies a control signal to the motor drive circuit 120 in order to stop the power supply from the battery 110 to the motor 160. On the other hand, in the third state, the control unit 100 supplies a control signal to the motor drive circuit 120 to perform regenerative charging when a predetermined condition for shifting to the regenerative charging mode is satisfied. Thereby, the battery 110 is charged with the electric power generated by the rotation of the motor 160.

  Further, when the mode selection button 185 is pressed for a predetermined period t2 (for example, 1 second) in the third state, the state is shifted to the second state. Thus, according to the bicycle with an electric motor according to the present embodiment, the assist by the motor 160 is effective and the light 170 is driven in the automatic lighting mode, and the assist by the motor 160 is stopped and the light 170 is turned on. It is possible to perform a direct switch between the third state in which is driven in the automatic lighting mode by long-pressing the mode selection button 185.

(Fourth state)
When the light button 186 is pressed in the second state, the state shifts to the fourth state. Further, when the mode selection button 185 is continuously pressed for a predetermined period t2 (for example, 1 second) in a fifth state to be described later, the state is shifted to the fourth state. In the fourth state, the control unit 100 forcibly turns on or off the light 170. That is, the control unit 100 switches on / off the light 170 in accordance with the operation of the light button 186 by the user regardless of the ambient brightness detected by the illuminance sensor 220. For example, when the light 170 is automatically turned on in the second state, when the light button 186 is pressed, the state shifts to the fourth state, and the control unit 100 turns the light 170 so that the light 170 is turned off. The drive circuit 130 is controlled. Thereafter, each time the light button 186 is pressed, the light 170 is switched on and off.

  Note that, in the fourth state, assist (generation of auxiliary driving force) and regenerative charging are enabled in the same manner as in the second state. When the mode selection button 185 is pressed in the fourth state, the assist mode can be switched. That is, every time the mode switching button 186 is pressed, the control unit 100 sequentially switches the assist mode to “power”, “standard”, “eco”, “power”,.

(5th state)
When the light button 186 is pressed in the third state, the state shifts to the fifth state. Further, when the mode selection button 185 is continuously pressed for a predetermined period t2 (for example, 1 second) in the fourth state, the state is shifted to the fifth state. When the mode selection button 185 is pressed for a period shorter than the predetermined period t2 (for example, 1 second) recognized as a long press in the fourth state, the assist mode is switched.

  In the fifth state, the stop of the assist by the motor 160 (generation of auxiliary driving force) is maintained, while the regenerative charging by the motor 160 is made effective as in the third state. In the fifth state, the control unit 100 forcibly turns on or off the light 170. That is, the control unit 100 switches on / off the light 170 in accordance with the operation of the light button 186 by the user regardless of the ambient brightness detected by the illuminance sensor 220. For example, when the light 170 is automatically turned on in the third state, when the light button 186 is pressed, the state shifts to the fifth state, and the control unit 100 turns the light 170 so that the light 170 is turned off. The drive circuit 130 is controlled. Thereafter, each time the light button 186 is pressed, the light 170 is switched on and off. Thus, according to the bicycle with an electric motor according to the present embodiment, the assist by the motor 160 is effective, and the light 170 is turned on and off in response to pressing of the light button 186, and the assist by the motor 160 is performed. Direct switching between the fifth state in which the light 170 is stopped and the light 170 is turned on and off in response to pressing of the light button 186 can be performed by long pressing the mode selection button 185.

  In the present embodiment, in the second to fifth states, when the light button 186 or the mode selection button 185 is continuously pressed for a predetermined period t1 (for example, 2 seconds), the first state ( That is, the power supply is turned off. That is, the mode selection button 185 long press period t2 required for performing the transition between the second state and the third state and the transition between the fourth state and the fifth state. By long-pressing the mode selection button 185 or the light button 186 over a long period t1, it is possible to shift from the second to fifth states to the first state.

  In addition, after the light 170 is automatically turned on according to the surrounding brightness, the light 170 is forcibly turned on or off from the fourth state and the fifth state. After shifting to the first mode (power off state) by the above operation, it is possible to shift to the second state and the third state.

  Further, as described above, for example, the control unit 100 determines that the host vehicle is continuously stopped for a predetermined period (for example, 3 minutes) based on detection signals supplied from the torque sensor 200 and the vehicle speed sensor 210. If this happens, it will switch to the power saving mode. When the control unit 100 shifts to the power saving mode, the control unit 100 supplies a control signal to the display control unit of the operation / display unit 180 to 187. When the display control unit 187 receives the control signal from the control unit 100, the display control unit 187 turns on the light emitting unit of the power saving mode display unit 184 and emits light from the remaining battery level display unit 181, the assist mode display unit 182, and the light lighting display unit 183. Turn off the light. In addition, when the control unit 100 shifts to the power saving mode, the control unit 100 controls the light driving circuit 130 so that the light 170 is maintained in the off state.

  When the control unit 100 determines that the state in which the host vehicle is stopped after shifting to the power saving mode continues for a predetermined period (for example, 2 minutes), the control unit 100 shifts to the first state (that is, the power-off state). . As a result, the control unit 100, the motor drive circuit 120, and the light drive circuit 130 are turned off, and all the light emitting units constituting the display units 181 to 184 in the operation / display unit 180 are turned off.
