[Prior Art] In recent years, cycling has become popular, in addition to the small size and non-energy consumption of bicycles, and it has also shown that modern people want to pursue healthier living patterns. In addition to being one of the many leisure activities for many people, bicycles have become a tool for some office workers and students to go to school. Because of this, the bicycle technology is more mature, and the traditional bicycle function has not been enough for modern people. Therefore, there are many kinds of products such as variable speed bicycles, folding bicycles, racing bicycles, and electric bicycles in the current bicycle market. Even so, how to make bicycle products more diverse and close to the general public's habits is still one of the goals that manufacturers are striving to achieve. SUMMARY OF THE INVENTION The present invention relates to a bicycle automatic shifting method and apparatus that can adjust an operating mode of a bicycle according to the state of the bicycle and the user.

In order to make the above description of the present invention more comprehensible, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: FIG. An elementary block diagram of a bicycle automatic transmission of an embodiment. As shown in Fig. 1, the bicycle automatic transmission 1 includes a torque meter 11, a gravity sensor 13, a revival speedometer 15, a transmission 17, a control module 19, and a heartbeat table 21. The torque meter 11 is preferably mounted or coupled to the pedal shaft of the bicycle 100 to measure the pedal torque data of the bicycle 100. This pedal torque data can be used to determine the user's foot strength and foot force changes. A gravity sensor 13 is mounted on the bicycle 100 to move with the bicycle 100. The gravity sensor 13 can sense the change of the acceleration force, wherein the acceleration force is the force acting on the object during the acceleration of the zero, so various movement changes such as shaking, rising, falling, etc. can be transformed by the gravity sensor 13. The electrical signal is then passed back to the control module 19 to detect the gravity sensing data of the bicycle 100. This gravity sensing data is used to determine whether the bicycle 100 is moving uphill, downhill or flat. The transmission 17 is coupled to the wheels of the bicycle 100 for changing the rotational speed of the wheels. The control module 19 is coupled to the torque meter 11, the gravity sensor 13, the tachometer 15, the transmission 17 and the heartbeat table 21 to receive data of such components, such as pedal torque data and gravity sensing data. 5 201132550 A... A* - The control module 19 includes a memory unit 23 and a processing unit 25. The memory unit 23 can be used to store one of the first operational modes of the bicycle 100 in its current operating state and a predetermined profile. The processing unit 25 is configured to compare data such as pedal torque data and gravity sensing data with preset data to generate a second operation mode from the preset data. The processing unit 25 then compares the second mode of operation with the first mode of operation to determine if the operational state of the bicycle has changed. When the operating state of the bicycle changes, the processing unit 25 switches the transmission 17 to a shifting state corresponding to the second operating mode to change the vehicle speed of the bicycle 100. The tachometer 15 is coupled to the control module 19 for measuring the rotational speed data of one of the bicycles 100. The heartbeat table 21 is also coupled to the control module 19 for measuring heartbeat data of one of the users. Both the heartbeat data and the return speed data may be used by the processing unit 25 to retrieve a data reference of the second operational mode from the preset data. Preferably, the preset data of the memory unit 23 includes a plurality of preset torque values for comparison, a preset gravity value, a preset return speed value, and a preset heartbeat value, and the preset values are transparent to the truth table. The format is stored in the memory unit 23. In addition, the memory unit 23 also stores a plurality of bicycle operation modes, including a leisure mode, a climbing mode, a downhill mode, and a sprint mode. The embodiment further discloses a bicycle automatic shifting method, which is a first operating mode in which the current operating state of the bicycle is recorded. Then, measure the pedal torque data of one of the bicycles. Next, grab one of the gravity sensing data of one of the bicycle gravity sensors. Then, the pedal torque data and the gravity sensing data are compared with one of the preset data of the bicycle to generate a second operation mode from the preset data. Next, the second operational mode and the first operational mode are compared to determine whether the bicycle operating state has changed. When the bicycle is running 201132550, the state of the bicycle is changed, and then one of the bicycle transmissions is switched to a shifting state corresponding to the second operating mode. In addition to determining the operating mode of the bicycle based on the pedal torque data and the gravity sensing data, it is preferable to refer to the user's heartbeat data and the bicycle's swing data together. Please refer to Fig. 2, which is a flow chart of a bicycle automatic shifting method in accordance with a preferred embodiment of the present invention, and also refers to the bicycle automatic shifting device 1 of Fig. 1. As shown in step S201 and Fig. 1, the first operation mode of the bicycle φ operating state is recorded first. The first mode of operation may be a casual mode, a hill climbing mode, a downhill mode, or a sprint mode. Next, as shown in step S202, the pedal torque data of one of the bicycles 100 is measured by the torque meter 11, and the pedal torque data is stored in the memory unit 23. Then, as shown in step S203, gravity sensing data of one of the gravity sensors 13 of the bicycle 100 is retrieved, and the gravity sensing data is stored in the memory unit 23. Next, as shown in step S204, one of the rotational speed data of the tachometer 15 of the bicycle 100 is read, and the rotational speed data is stored in the memory unit 23. Then, as shown in step S205, the heartbeat data of one of the users measured by the heartbeat table 21 is read and stored in the memory unit 23. Next, as shown in step S206, it is judged whether or not the number of times of reading data is larger than a predetermined number of times. When the number of readings has not reached the predetermined number of times, the process returns to step S202, and the pedal torque data of the bicycle is measured once, and steps S203 to 205 are sequentially performed until the number of readings is greater than the predetermined number of times. The number of readings 7 201132550 can be set according to the design of the device and the needs of the user. Although the embodiment is an example of repeated reading, the present embodiment is not limited thereto, and may be performed immediately after the data is taken once. Judging the operation mode 2 of the bicycle, after the number of readings is greater than the predetermined number of times, as shown in step S2〇7, the pedal pedal torque data, the gravity sensing data, the average value of the data, and the bicycle-pre-speed data and the heartbeat 褚The machine carefully pre-empted and pre-0 and Beko made a comparison to generate a second mode of operation from the pre-5 and Becco.

For example, assuming that the first operation mode recorded in step S201 is the leisure mode, the second operation mode generated in step S207 is a sprint mode, and the second operation mode is different from the first operation mode, representing the state of the bicycle. changed. Then, as shown in step S210, the bicycle transmission is switched to a shifting state corresponding to one of the second operating modes. The leisure mode, the climbing mode, the downhill mode, and the sprint mode have different bicycle states. For example, in the leisure mode, it is preferable to have a low rotation speed, a low heart rate, and a gear ratio of the center alignment, and it is preferable to set the suitability. In the climbing mode, it is low speed, high heartbeat, and the gear ratio is small to large, and the labor saving setting is better. In the downhill mode, for high speed, low heart rate, the gear ratio is set to a large to small speed, and safety considerations are preferred. In the sprint mode, the high speed, high heart rate, gear ratio is large to medium or large to small. The bicycle automatic transmission device 1 of the present embodiment firstly detects the change of the user's foot force by using the torque meter 11, and simultaneously grabs the data of the gravity sensor 13 to the processing unit 25 to confirm whether it is climbing, downhill or flat. It is judged that the acceleration or deceleration is performed. In addition, the detected tachometer 15 and the heartbeat table 21 simultaneously transmit the detected data to the processing unit 25. The processing unit 25 uses the read data data, and after passing through an appropriate algorithm, determines whether the transmission 17 should enter or retreat to further forward the command of the bicycle 100 (not shown) to forward or Reverse and make the strander (not shown π 201132550 • »f ri) drive the front or rear shift, and enter (4) to the purpose of automatic shifting. The automatic transmission device 1 and method of the vehicle are based on the torque meter 1!, the gravity sensor 13, the tachometer 15, the transmission port and the heart, and the amount of data remaining in the table 21 is not limited. herein. Referring to Figure 3, there is shown a block diagram of an element of a bicycle automatic transmission according to another preferred embodiment of the present invention. As shown in Fig. 3, the bicycle automatic transmission 3 includes a state sensing device 31, a transmission %, and a control module 35. The state sensing device 3 is configured to sense a self-condition parameter. The transmission 33 is connected to the bicycle! (8) - the wheel. The control module .35 is coupled to the state sensing device 31 and the transmission 33 to receive the state parameters of the bicycle 100. The control module 35 includes a memory unit 37 and a processing unit 39. The memory unit 37 can store one of the first operation modes of the bicycle 1 current operating state and a preset data. The processing unit 39 is configured to compare the state parameter of the bicycle 100 with the preset data to generate a second operation mode from the preset data, and compare the second operation mode with the first operation mode to determine the operation state of the bicycle 100. Whether or not the change is made, wherein when the operating state of the bicycle 100 is changed, the processing unit 39 switches the transmission 33 to a shifting state corresponding to one of the second operating modes. Preferably, the state sensing device 31 can be a torque meter, a gravity damper, a heart rate meter, a tachometer, or any combination of these elements. The status parameter may be one of the bicycle pedal torque data, one of the bicycle's gravity sensing data, one of the user's heartbeat data, or one of the bicycle's return speed data, or any combination of these data. Therefore, the bicycle automatic shifting device 3 can determine the operation mode required for the bicycle 12 201132550 i 100 based on a single data or a plurality of data to determine whether to switch the transmission 33 to conform to the actual operating state of the bicycle 100 and the physical condition of the user. In the above, the present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
