  In the example shown in FIG. 4, a control map M11 to M13 used when traveling on a flat road and a control map M21 used when traveling on a downhill are set. In the control map M21, when the value of the inclination angle α indicates a downhill (a negative value greater than or equal to a predetermined magnitude), the auxiliary driving force ta is reduced compared to the control maps M11 to M13. .

(Operation of the driving force control device for a battery-assisted bicycle)
Next, the operation of the driving force control apparatus 100 will be described. Specifically, an operation for lowering the auxiliary driving force ta when it is determined that the battery-assisted bicycle 10 is traveling on a downhill compared to when the battery-assisted bicycle 10 is traveling on a flat road will be described.

  FIG. 3 is an operation flowchart of the driving force control apparatus 100. As shown in FIG. 3, in step S10, the driving force control device 100 detects human power torque. Specifically, the driving force control apparatus 100 calculates the human power torque based on the total torque of the human power torque and the motor torque detected by the torque detection unit 107.

  In step S20, the driving force control apparatus 100 detects the inclination angle α of the road surface R on which the battery-assisted bicycle 10 travels. In step S30, the driving force control apparatus 100 detects the crankshaft rotation speed VR. In step S40, the driving force control apparatus 100 detects the traveling speed V. Note that the processing in steps S10 to S40 may be executed simultaneously instead of in time series.

  In step S50, the driving force control apparatus 100 determines whether or not the battery-assisted bicycle 10 is traveling downhill based on the detected inclination angle α. In addition to the inclination angle α, the driving force control apparatus 100 may determine that the vehicle is traveling on a downhill when the traveling speed V is equal to or greater than a predetermined value.

When the battery-assisted bicycle 10 is traveling downhill (YES in step S50), in step S60, the driving force control device 100 refers to the control map. Specifically, the driving force control device 100, based on the detected inclination angle α and the crankshaft rotation speed V R, determining whether to use the control map used at the time of traveling downhill M21 (see FIG. 4) To do. Here, it is assumed that the control map M21 is selected.

  In step S70, the driving force control apparatus 100 determines whether or not the auxiliary driving force ta needs to be reduced based on the referenced control map M21.

  When it is necessary to reduce the auxiliary driving force ta (YES in step S70), in step S80, the driving force control device 100 decreases the auxiliary driving force ta. Specifically, the driving force control device 100 makes the torque (motor torque) of the electric motor 111 lower than when the battery-assisted bicycle 10 is traveling on a flat road.

(Action / Effect)
According to the driving force control apparatus 100, when it is determined that the battery-assisted bicycle 10 is traveling on a downhill, the assist driving force ta is lower than that when the battery-assisted bicycle 10 is traveling on a flat road. That is, when the battery-assisted bicycle 10 is traveling on a downhill, power consumption is suppressed by reducing the torque (motor torque) generated by the electric motor 111. Note that the auxiliary driving force ta is low when the battery-assisted bicycle 10 is traveling downhill, so that the rider does not feel uncomfortable due to the decrease in the auxiliary driving force ta. That is, according to the driving force control apparatus 100, the cruising distance of the battery-assisted bicycle 10 can be further extended without changing the magnitude or opportunity of the practical auxiliary driving force ta.

  Furthermore, since power consumption by the electric motor 111 is suppressed, a smaller and lighter battery 50 can be used. Further, since power consumption by the electric motor 111 is suppressed, it is not necessary for the rider to provide a mode switching unit that switches between the normal mode (power mode) and the power saving mode according to the exhausted state of the battery 50.

  In the present embodiment, the driving force control apparatus 100 can determine whether or not to reduce the auxiliary driving force ta based on the crankshaft rotational speed VR. Specifically, even when the battery-assisted bicycle 10 is traveling downhill, if the rider is stroking the crank pedal 41 at a predetermined speed or higher, the same auxiliary driving force ta as that on a flat road can be generated. it can.

  That is, even when the battery-assisted bicycle 10 is traveling downhill, if the rider needs the auxiliary driving force ta, the auxiliary driving force ta similar to that on a flat road can be generated.

  In the present embodiment, the driving force control device 100 controls the auxiliary driving force ta based on the control map stored in the storage unit 115. For this reason, the control pattern of the auxiliary driving force ta can be easily changed by rewriting the contents of the control map stored in the storage unit 115.
