no. 1 approach

[0038] refer to Figure 1 to Figure 5 The bicycle control device will be described.

[0039] In the following description, "left side" means the left-hand side of the user riding on the power-assisted bicycle (bicycle), and "right side" means the right-hand side of the user riding on the power-assisted bicycle. "Front" indicates the forward direction of the power-assisted bicycle. "Rear" indicates the reverse direction of the electric assist bicycle.

[0040] figure 1 In , an example of a power-assisted bicycle provided with a bicycle control device is shown.

[0041] The power-assisted bicycle includes a frame 2, a pair of wheels (a front wheel 4 and a rear wheel 6) rotatably mounted on the frame 2, a drive mechanism 8 for driving the rear wheel 6, and a drive mechanism 8 for changing the direction of the front wheel 4. The handlebar 10, the seat 12, the battery 14, the operation part 16 and the display part 18.

[0042] The operation unit 16 and the display unit 18 are ...

no. 2 approach

[0100] refer to Figure 6 , the control unit 32 of another embodiment will be described. The control unit 32 of the present embodiment has the same configuration as the control unit 32 shown in the first embodiment. In the following description, the corresponding components to those of the control unit 32 shown in the first embodiment are denoted by the same reference numerals for each component.

[0101] The control unit 32 of the present embodiment differs from the control unit 32 of the first embodiment in the mode switching process executed. In particular, the processing regarding the first operation switch 42 is different. Since the processing of the second operation switch 44 is the same as the mode switching processing in the first embodiment, description thereof will be omitted. Figure 6 followed by the "A" shown in Figure 5 "A". Hereinafter, processing related to the first operation switch 42 will be described.

[0102] In the control unit 32 of this embodimen...

no. 3 approach

[0112] refer to Figure 7 , and another embodiment of the operation unit 16 and the display unit 18 will be described. Hereinafter, the same components as those of the operation unit 16 and the display unit 18 shown in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. In addition, in the first embodiment, the input unit 34 is provided independently of other devices, but in the present embodiment, a part of the function of the operation unit 16 as the input unit 34 is provided in the shift operation unit 62 .

[0113] The operation unit 16 has a second operation switch 44 and a first operation switch 42 as the input unit 34 . The second operation switch 44 and the first operation switch 42 have the same functions as those of the second operation switch 44 and the first operation switch 42 shown in the first embodiment, and the operation mode can be changed, but they cannot be driven in the walking mode. Or stop the motor...

Abstract

The invention provides a bicycle control device, a motor assist bicycle with the bicycle control device, and a motor control method for the motor assist bicycle. Assisting of driving of a wheel can be achieved during a user pushes a bicycle and walks according to the intention of the user. The bicycle control device includes an input unit and a controller that switches, when the input unit is operated, between a ride mode that controls the motor in correspondence with manual driving force and a walk mode that drives the motor in correspondence with the operation of the input unit. After switching to the walk mode, the controller drives the motor in correspondence with the operation of the input unit.

Description

technical field [0001] The present invention relates to a bicycle control device, a power-assisted bicycle provided with the bicycle control device, and a motor control method of the power-assisted bicycle. Background technique [0002] There is known a power-assisted bicycle that drives a motor to assist wheel drive not only when riding a bicycle but also when pushing the power-assisted bicycle for walking. [0003] The motor-assisted bicycle described in Patent Document 1 is provided with a switch for walking with the cart. When the switch for walking with a stroller is pressed, the control device of this electrically-assisted bicycle determines whether or not it is in a walking with a stroller based on the pedaling force acting on the pedals and the rotational speed of the crank shaft. Then, the control device drives the motor in a predetermined mode when it determines that the vehicle is in the walking state while pushing the cart. The switch for strolling and walking ...
