Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and particularly relates to a control method, system and electronic transmission for an electronic transmission. Background Technology

[0002] With the popularization of cycling and technological upgrades, traditional mechanical cable-driven derailleurs, due to their limited operational precision and the tendency for cables to wear out easily and affect performance, can no longer meet users' high demands for shifting response speed, accuracy, and stability. Against this backdrop, electronic derailleurs have emerged. They replace the traditional mechanical cable-driven force transmission method by using electronic switches to trigger signals and motors to drive the shifting mechanism. This results in faster and more precise gear shifting, significantly improving the riding experience and becoming one of the core features of bicycles.

[0003] However, electronic transmissions consume a lot of power when in operation. Currently, the batteries in electronic transmissions on the market are small, resulting in low battery capacity and requiring frequent charging to maintain operation. Furthermore, electronic transmissions cannot enter a sleep state while charging, which greatly reduces the standby time and battery life. Alternatively, if an electronic transmission enters a sleep state after being unused for a long time, it cannot be woken up and immediately enters working mode, preventing users from using it immediately and resulting in a poor user experience.

[0004] Therefore, the technical problem to be solved by this invention is how to design a technology to improve the standby time of electronic transmissions and enhance user experience. Summary of the Invention

[0005] This invention provides a control method, system, and electronic transmission for an electronic transmission, thereby improving the standby time of the electronic transmission and enhancing the user experience.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In one aspect, the present invention provides a control method for an electronic transmission, comprising the following steps: S1, Collect button information of the electronic transmission, and determine the initial operating state of the electronic transmission based on the button information. The initial operating state includes low-frequency use state, medium-frequency use state and high-frequency use state. S2, the buttons are inspected using different inspection modes according to different initial working states, and the information of the buttons is detected subsequently; the inspection modes include a first inspection mode, a second inspection mode, and a third inspection mode. The first inspection mode is used in the low-frequency use state, the second inspection mode is used in the medium-frequency use state, and the third inspection mode is used in the high-frequency use state. The inspection frequencies of the first inspection mode, the second inspection mode, and the third inspection mode are different. S3, collect the acceleration data of the electronic transmission, and switch the inspection mode of the button according to the changes in the acceleration data; S4, according to the inspection mode, the electronic transmission inspects the button and executes the gear shift command according to the button information.

[0007] In the electronic transmission control method described above, the method for determining the initial operating state of the electronic transmission based on the button information in step S1 is as follows: If no trigger signal is detected for the button, the initial state of the electronic transmission is a low-frequency operation state. If a click trigger signal is detected for the button, the initial state of the electronic transmission is the medium-frequency operation state; If a double-click trigger signal of the button is detected, the initial state of the electronic transmission is a high-frequency use state.

[0008] In the control method of the electronic transmission described above, the first inspection mode is that the buttons of the electronic transmission are inspected for only a seconds within each inspection cycle of x seconds, where a < x; the second inspection mode is that the buttons of the electronic transmission are inspected for only b seconds within each inspection cycle of x seconds, where b < x; the third inspection mode is that the buttons of the electronic transmission are continuously inspected; wherein b is greater than a.

[0009] In the electronic transmission control method described above, the method for switching the button's inspection mode based on changes in the acceleration data in step S3 is as follows: If the acceleration data remains unchanged within a time threshold range, the system switches to the first inspection mode to inspect the button; if the acceleration data changes and the rate of change is within a set threshold range, the system switches to the second inspection mode to inspect the button; if the acceleration data changes and the rate of change exceeds the set threshold range, the system switches to the third inspection mode to inspect the button.

[0010] In another aspect, the present invention provides a control system for an electronic transmission, comprising: The hand-operated unit includes buttons and a first controller, the first controller being connected to the buttons and used to collect information from the buttons; The transmission actuator includes an acceleration sensor and a second controller, the second controller being connected to the acceleration sensor; the acceleration sensor is used to detect the acceleration information of the electronic transmission, the second controller is used to collect the acceleration information and determine the inspection mode of the button based on the acceleration information, and the second controller is also used to receive the button information and execute the transmission command; A communication unit is provided to enable the first controller and the second controller to communicate with each other.

[0011] In some embodiments of this application, both the first controller and the second controller employ an MCU (Microcontroller Unit).

[0012] In some embodiments of this application, the communication unit employs 2.4GHz wireless technology.

[0013] In another aspect, the present invention provides an electronic transmission, including an electronic transmission body, wherein the electronic transmission body applies the control method described above.

[0014] In another aspect, the present invention provides a computer-readable storage medium, The computer-readable storage medium stores computer-executable instructions, which, when executed by a processor, are used to implement the method described above.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: (1) The control method determines the initial working state of the electronic transmission by collecting the initial key information of the electronic transmission, and determines different inspection modes to inspect the keys according to different initial working states, and detects the information of subsequent keys; then, by collecting the acceleration data of the electronic transmission, it determines whether the working state of the electronic transmission has changed during operation, and adjusts the inspection mode according to the changes in acceleration data. Different inspection modes have different inspection frequencies, so the power consumption of the electronic transmission is also different. This ensures that the electronic transmission can respond in time when the key is pressed and can be put into use immediately, ensuring the stability of the working state; and also ensures that the electronic transmission is used with the minimum power consumption throughout the process, reducing standby power consumption and extending standby time and battery life. (2) The control system collects information from the buttons by setting a first controller in the manual shift unit. When a button is pressed, the second controller in the shift execution unit is woken up. The acceleration data of the electronic transmission is collected by the acceleration sensor in the shift execution unit, thereby obtaining information on the change of the working state of the electronic transmission. This allows the second controller to adjust the inspection mode of the buttons in time. Finally, the shift command is executed by the second controller. The device is simple in principle and easy to operate, which greatly improves the user experience. Attached Figure Description

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] like Figure 1As shown, this application provides a control method for an electronic transmission. By setting different inspection frequencies for button inspection under different operating states, the power consumption of the electronic transmission is greatly reduced, thereby increasing the standby time of the electronic transmission and extending the battery life. The control method includes the following steps: S1 collects the button information of the electronic transmission and determines the initial operating state of the electronic transmission based on the button information. The initial operating state includes low-frequency operation state, medium-frequency operation state and high-frequency operation state.

[0025] The specific details of determining the initial operating state of the electronic transmission based on button information can be set according to actual needs. In this application, the method for determining the initial operating state of the electronic transmission based on button information is as follows: If no trigger signal is detected for the button, meaning the user has not pressed the button, it indicates that the electronic gear shifter is in a low-frequency operation state initially. This low-frequency operation state can be applied in scenarios where the user is not riding.

[0026] If a single click trigger signal is detected, indicating that the user has clicked the button, it means that the electronic gear shifter is initially in the mid-frequency operation mode. The mid-frequency operation mode can be used when the user is using the electronic gear shifter for relatively dispersed riding activities.

[0027] If a double-click trigger signal is detected, indicating that the user double-clicked the button, it means that the electronic shifter is initially in a high-frequency usage state. This high-frequency usage state is suitable for situations where multiple users are using the electronic shifter for concentrated riding activities. It is applicable in situations requiring frequent gear changes, thus placing higher demands on the electronic shifter's performance.

[0028] S2 performs inspections on the buttons using different inspection modes according to different initial working states, and detects the information of subsequent buttons. The inspection modes include the first inspection mode, the second inspection mode, and the third inspection mode. The first inspection mode is used when the operation is in low-frequency state, the second inspection mode is used when the operation is in medium-frequency state, and the third inspection mode is used when the operation is in high-frequency state. The inspection frequencies of the first inspection mode, the second inspection mode, and the third inspection mode are different.

[0029] Because the requirements for the electronic transmission's shifting speed differ between low-frequency, medium-frequency, and high-frequency operating states, the required responsiveness of the electronic transmission also varies in these three states. Since the degree of requirement for the electronic transmission's shifting speed increases from low to high, the inspection frequency also increases from low to high in these three states. A higher inspection frequency indicates more timely detection of button changes, resulting in higher shifting sensitivity. The first inspection mode involves inspecting the electronic transmission's buttons for only a seconds within each inspection cycle of x seconds, where a < x; the second inspection mode involves inspecting the electronic transmission's buttons for only b seconds within each inspection cycle of x seconds, where b < x; the third inspection mode involves continuous inspection of the electronic transmission's buttons, where b is much greater than a. S3: Collect the acceleration data of the electronic transmission and switch the button inspection mode based on changes in the acceleration data.

[0030] Because the operating status changes constantly during riding, the inspection mode can be adjusted according to these changes to reduce the power consumption of the electronic gearbox. The operating status during riding is represented by changes in the acceleration data of the electronic gearbox.

[0031] If the acceleration data remains unchanged within the time threshold range, switch to the first inspection mode to inspect the button; if the acceleration data changes and the rate of change is within the set threshold range, switch to the second inspection mode to inspect the button; if the acceleration data changes and the rate of change exceeds the set threshold range, switch to the third inspection mode to inspect the button.

[0032] It should be noted that "acceleration data remains unchanged" means that the magnitude of acceleration across all three axes does not change. There is also a special case where the acceleration magnitude is 0. The threshold time range can be set to 120 seconds. This time range can prevent accidental user operation and more accurately determine changes in acceleration data, thereby more precisely adjusting the button inspection mode and improving the user experience.

[0033] Changes in acceleration data refer to changes in the magnitude of at least one of the three axes of acceleration. Changes in acceleration data can be set to occur at the instant of acquisition or within a threshold range of acquisition time. For example, the rate of change of acceleration data within 5 seconds can be set. The instantaneous change or the change within a threshold range of acquisition time can be set according to actual usage requirements.

[0034] S4, according to the inspection mode, the electronic gearbox inspects the buttons and executes the gear shift command according to the button information.

[0035] like Figure 2 As shown, this application provides a control system for an electronic transmission, including: The manual shift unit 100 includes a button 101 and a first controller 102. The first controller 102 is connected to the button 101 and is used to collect information from the button 101. When the first controller 102 detects that the button 101 is pressed, the second controller 202 is activated and can execute the speed shift command.

[0036] The transmission execution unit 200 includes an acceleration sensor 201 and a second controller 202. The second controller 202 is connected to the acceleration sensor 201. The acceleration sensor 201 is used to detect the acceleration information of the electronic transmission. The second controller 202 is used to collect the acceleration information and determine the inspection mode of the button 101 based on the acceleration information. The second controller 202 is also used to receive the information from the button 101 and execute the transmission command.

[0037] Communication unit 300 is used to enable communication between the first controller 102 and the second controller 202.

[0038] In some embodiments of this application, both the first controller 102 and the second controller 202 employ an MCU (Microcontroller Unit). MCUs offer advantages such as high integration and low power consumption, which helps to further reduce the power consumption of the electronic transmission and extend battery life.

[0039] In some embodiments of this application, the communication unit 300 employs 2.4GHz wireless technology. 2.4GHz wireless technology has the advantages of strong anti-interference capability and high data transmission stability, making it convenient for use in complex cycling environments; 2.4GHz wireless technology also has the advantages of low power consumption and small device size, which helps reduce the power consumption of the electronic gearbox and extend battery life.

[0040] Through extensive experimentation, this application provides an optimal embodiment of a control method for an electronic transmission, as detailed below: The first inspection mode is that the first controller 102 works for only 2.5ms every 1 second to inspect the button 101, that is, the first controller 102 only works periodically for 2.5ms every 1 second to detect whether the button 101 has a trigger signal; the second inspection mode is that the first controller 102 works for 600ms every 1 second to inspect the button 101, that is, the first controller 102 only works periodically for 600ms every 1 second to detect whether the button 101 has a trigger signal; the third inspection mode is that the first controller 102 works for 1 second every 1 second to inspect the button 101, that is, the first controller 102 keeps working continuously to inspect the button 101 and detect whether the button 101 has a trigger signal.

[0041] If the acceleration data remains unchanged, switch to the first inspection mode to inspect button 101; if the acceleration data changes and the rate of change is less than or equal to 50%, switch to the second inspection mode to inspect button 101; if the acceleration data changes and the rate of change is greater than 50%, switch to the third inspection mode to inspect button 101.

[0042] Table 1. Comparison of power consumption and charging frequency of the electronic transmission using this application and prior art.

[0043] As can be seen from Table 1 above, after using this application, the power consumption of the electronic transmission is greatly reduced. Reduced power consumption means less electricity usage, resulting in longer standby time for the same battery size, and eliminating the need for frequent charging, thus extending battery life. Combined with... Figure 3 As shown, when the electronic gearbox is turned on, the button 101 is inspected in the first inspection mode. In the first inspection mode, the first controller 102 is considered to be in a semi-dormant state, which can reduce power consumption. When the button 101 is first detected to be pressed, the second controller 202 is awakened and enters the working state. At the same time, the second controller 202 can execute the gear shift command. Then the second controller 202 determines whether the acceleration data has changed. If there is no change, the first controller 102 remains in a semi-dormant state, that is, it continues to inspect in the first inspection mode. If the acceleration data changes, the first controller 102 enters the working state and inspects in the second inspection mode or the third inspection mode.

[0044] In another aspect, this application also provides an electronic transmission, including an electronic transmission body, wherein the electronic transmission body applies the control method described above.

[0045] In another aspect, this application also provides a computer-readable storage medium, The computer-readable storage medium stores computer-executable instructions, which, when executed by a processor, are used to implement the control method described above.
