[0028] Reference Figure 1 , Figure 1 The present invention is a schematic diagram of the structure of a self-service gear shifting device for power-assisted bicycle riding in the hardware operating environment involved in the embodiment of the present invention.

The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0030] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the self-service gear shifting device for assisting bicycle riding, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0031] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a self-service gear shifting program for assisting bicycle riding.

[0032] exist Figure 1 In the self-service gear shifting device for power-assisted bicycle riding shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the self-service gear shifting device for power-assisted bicycle riding of the present invention can be set in the self-service gear shifting device for power-assisted bicycle riding, and the self-service gear shifting device for power-assisted bicycle riding calls the self-service gear shifting program for power-assisted bicycle riding stored in the memory 1005 through the processor 1001, and executes the self-service gear shifting method for power-assisted bicycle riding provided by the embodiment of the present invention.

[0033] The embodiment of the present invention provides a self-service gear shifting method for power-assisted bicycle riding, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a self-service gear shifting method for power-assisted bicycle riding according to the present invention.

[0034] In this embodiment, the self-service gear shifting method for riding a power-assisted bicycle comprises the following steps:

[0035] Step S1, obtaining a user's riding parameters, and determining a transmission gear and a motor assist ratio suitable for the user according to the riding parameters;

[0036] It should be noted that in the specific implementation, the parameters of the user's riding include cadence, torque and speed; by comparing the general riding parameter range with the current user's riding parameters, it is determined whether the current user's riding parameter range is within the general riding parameter range, and then the transmission gear and motor power ratio suitable for the user are determined. When the user's riding speed is greater than or less than the general riding parameter range, the transmission and motor adjust the gear to ensure that the user always rides in a comfortable cadence range and appropriate torque; for example, if the speed is slow, the torque is large, and the cadence is slow, the user needs to climb a slope; if the cadence is fast, the torque is weak, and the speed is fast, it means that the user is pedaling in vain and is downhill; when the speed is fast, the torque is large and the cadence is fast, it means that the user wants to accelerate; if the speed is within a certain range (such as greater than or equal to 30kM / h), the cadence slows down, but the speed is still within a certain range; so when obtaining the user's riding parameters, it is necessary to make a comprehensive judgment based on the cadence, torque, and speed;

[0037] Step S2, obtaining riding scene parameters, and adjusting the transmission gear and the motor assist ratio according to the riding scene parameters;

[0038] It should be noted that in a specific implementation, the parameters of the riding scene are collected, the riding road conditions and the slope of the riding road conditions are determined, and the transmission gear and the motor assist ratio are adjusted according to the riding scene parameters;

[0039] Furthermore, the transmission is adjusted up and down according to the user's comfortable pedaling range (when the force is greater than the comfortable pedaling range, the transmission reduces the gear ratio, and when it is less than the comfortable pedaling range, the transmission increases the gear ratio). When it is detected that the user's force is still outside the comfortable pedaling range for a long time after the transmission gear is adjusted, the output power of the motor is further increased to provide sufficient power for the user; the specific transmission gear and motor gear decisions are made based on the scene of the vehicle (such as uphill, downhill, flat road, sliding, muddy, gravel road...) and the user's comfortable pedaling range for comprehensive judgment;

[0040] Step S3, performing self-service gear shifting on the bicycle according to the transmission gear position and the motor assist ratio adjusted in step S2.

[0041] refer to Figure 3 , Figure 3 The figure is a flow chart of a second embodiment of a self-service gear shifting method for power-assisted bicycle riding according to the present invention.

[0042] Based on the above-mentioned first embodiment, in this embodiment, the self-service shifting method also includes step S0: the step S0 is to determine whether the user is riding for the first time. If so, the user is required to manually operate the transmission to ride and collect the user's riding parameters, and determine the transmission gear and motor assist ratio suitable for the user based on the riding parameters and the shifting timing; if not, determine the transmission gear and motor assist ratio suitable for the user in combination with the user's riding status.

[0043] More specifically, when the user rides for the first time, he or she will ride a distance according to the user's habits. The mainboard will communicate with the mobile phone APP via Bluetooth, and the user will interact with the vehicle through the mobile phone APP. At the same time, the main control board will store the collected information such as the user's cadence, torque, speed and shift timing during riding, and generate a cadence range and torque limit range suitable for the user's transmission shift through an algorithm. When the user's riding speed is greater than or less than this range, the transmission and motor will adjust the gear position to ensure that the user always rides in a comfortable cadence range and appropriate torque.

[0044] refer to Figure 4 , Figure 4 The figure is a flow chart of a third embodiment of a self-service gear shifting method for power-assisted bicycle riding according to the present invention.

[0045] Based on the above-mentioned first embodiment, in this embodiment, it is determined whether the riding parameters of the user are within the general riding parameter range according to the current riding scene parameters. If so, the current transmission gear is maintained; if not, the gear of the transmission is adjusted. After adjusting the gear of the transmission, if the riding parameters of the user are still outside the general riding parameter range, the power assistance ratio of the motor is adjusted.

[0046] In this embodiment, the determination of whether the user is riding for the first time is performed by identifying the user's biological characteristics, key or smart card; the riding scene parameters in step S2 include slope level and road conditions.

[0047] It should be noted that in the specific implementation, identification based on the user's biological characteristics includes fingerprint, facial recognition, iris scanning, etc. to confirm the identity, key-based identification includes entering the correct key or password to identify the user; smart card-based identification determines whether it is the same user by swiping the card.

[0048] It should be noted that in a specific implementation, the slope level is collected by a perception module and the real-time slope is determined. The perception module includes a gyroscope or other components that can identify the slope.

[0049] The riding scene parameters also include road condition scene images, which are collected by a camera module to determine the real-time road conditions. The camera module may include a camera image processing module.

[0050] In the process of adjusting the transmission gear and the motor assist ratio, they can also be adjusted in combination with the road scene image.

[0051] Taking into account the differences in riding experience, physical condition and riding environment of each type of user, it is necessary to collect the user's personal riding habits before the user officially uses it. When using it specifically, it is necessary to first start the initial riding program, manually operate the transmission and motor assist to ride a certain mileage, collect riding parameters and riding scene parameters, and finally complete the user's exclusive automated operation logic by determining the user portrait and fitting the self-service shifting method for assisted bicycle riding.

[0052] When the user starts a cycling activity, the system determines the user's cycling status and cycling scene changes, and performs automatic gear shifting operations on the transmission and motor. After each cycling activity, the user can propose improvement plans and fine-tune the self-service gear shifting method for assisted bicycle riding based on the current cycling experience. The system also integrates user cycling data based on relevant user portraits and cycling scenes and stores it in the cloud.

[0053] In this embodiment, the step S2 further includes obtaining the user's physical parameters, and adjusting the transmission gear and the motor assist ratio according to the user's physical parameters, the riding parameters, and the riding scene parameters.

[0054] More specifically, based on the general standards of healthy cycling (such as cadence, power, heart rate, etc.), the pedaling data and physical conditions of various users are collected and combined to fit a set of comfortable pedaling ranges that cover most users. Combined with the environmental perception module, the main control will issue a command and coordinate the switching of the transmission motor gear when the range is exceeded or lower than this range, so as to ensure a healthy cadence and pedaling force during cycling.

[0055] refer to Figure 5 , Figure 5 This is a structural block diagram of a first embodiment of a self-service gear shifting device for assisting bicycle riding according to the present invention.

[0056] like Figure 5 As shown, a self-service gear shifting device for power-assisted bicycle riding, the self-service gear shifting device for power-assisted bicycle riding comprises:

[0057] User data collection module: obtains user riding parameters, and determines the transmission gear and motor assist ratio suitable for the user according to the riding parameters;

[0058] A riding scene acquisition module: obtaining riding scene parameters, and adjusting the transmission gear and the motor assist ratio according to the riding scene parameters;

[0059] Control module: performs self-service gear shifting on the bicycle according to the adjusted transmission gear position and the motor assist ratio.

[0060] It should be noted that in the specific implementation, the control module includes a main control board, a mid-mounted motor (hub motor) and a transmission, wherein the main control board is connected to torque, cadence, speed, gyroscope and other sensors through a CAN bus architecture.

[0061] It is understandable that the self-service gear shifting device for power-assisted bicycle riding is connected to a terminal device, which is a mobile phone, computer, tablet or other device with a display screen, and the user can see the status of the self-service gear shifting device for power-assisted bicycle riding in real time on the terminal device. The user can authenticate the identity through the terminal device.

[0062] A prototype vehicle equipped with a self-service gear-shifting device for power-assisted bicycle riding was tested against a bicycle without the device on the same road. The prototype vehicle equipped with a self-service gear-shifting device for power-assisted bicycle riding provided better riding continuity, ease of use and comfort than the bicycle without the device.

[0063] The self-service gear shifting device equipped with power-assisted bicycles effectively increases the battery life of the vehicle. According to the test quantification, the battery life of the vehicle with the automatic gear shifting function turned on is increased by more than 30% compared with that without the automatic gear shifting function under the same riding environment and route. The specific reason is that compared with ordinary electric power-assisted bicycles, the self-service gear shifting device equipped with power-assisted bicycles can adjust the output of the motor in real time according to the riding status, thereby saving electricity.

[0064] According to user test feedback, the self-service gear shifting device equipped with power-assisted bicycles effectively improves riding efficiency during riding, reduces the learning cost of shifting gears and cooperating with electric assistance, and makes the acceleration during riding more continuous. At the same time, the riding concentration brought about by freeing up your hands is unprecedented, and greater concentration means greater safety.

[0065] It should be understood that the above is only an example and does not constitute any limitation on the technical solution of the present invention. In specific applications, technicians in this field can make settings as needed, and the present invention does not limit this.

[0066] It should be noted that the workflow described above is merely illustrative and does not limit the scope of protection of the present invention.
