[0022] In order to solve the problem in the prior art that the transmission, power-assisted motor, smart lock, power supply and other devices on the bicycle are not compatible and cannot be uniformly managed and controlled and parameter adjusted, the present application provides a parameter adjustment method, which pre-stores the communication protocols corresponding to each device, obtains the parameter adjustment instructions entered in the parameter adjustment interface, and calls the corresponding target communication protocol to send the parameter adjustment instructions to the target device. The user can uniformly adjust the parameters of other devices through one device, thereby simplifying the parameter adjustment process, improving the adjustment efficiency, and thus improving the user's riding experience.

[0023] The parameter adjustment method provided in the present application is executed on a control device, which may be a terminal device installed on a bicycle, or may include a handheld terminal and a controller, or may include a terminal device and a server. The handheld terminal may be a terminal installed on the handlebar of a bicycle.

[0024] The parameter adjustment method provided in this application is exemplified below.

[0025] Please see attached Figure 1 , a parameter adjustment method provided in an embodiment of the present application includes: S101: Displaying a parameter adjustment interface.

[0026] Specifically, the control device includes a display screen, which can display a parameter adjustment interface according to the user's input instructions. Exemplarily, the control device includes a handheld terminal and a controller, the handheld terminal includes a display screen, and the controller is connected to the transmission, motor, smart lock, power supply, indicator light, speaker, etc., and instructs the handheld terminal to display a parameter adjustment list of the transmission, motor, smart lock, power supply and other devices on the display screen. Among them, the transmission is used to change the input and output speed ratio of the bicycle according to the instructions of the controller, so as to change the speed. The motor is used to provide power to the bicycle or stop providing power according to the instructions of the controller. The smart lock is used to lock the bicycle according to the instructions of the controller. The power supply is used to power other devices according to the instructions of the controller.

[0027] S102: Acquire the parameter adjustment instruction input in the parameter adjustment interface.

[0028] Specifically, the parameter adjustment instruction is an instruction for adjusting the parameters of any one or more devices among the transmission, motor, smart lock, and power supply. The parameter adjustment instruction can be input by the vehicle manufacturer before assembling the bicycle, or by the user during the use of the bicycle.

[0029] In one embodiment, the parameter adjustment interface displays the current parameters of the transmission, motor, smart lock, and power supply.

[0030] Exemplarily, the control device pre-stores the communication protocols corresponding to the transmission, motor, smart lock, power supply and other devices. For the target device, the corresponding target communication protocol is called to communicate with the target device to obtain the current parameters of the target device, and the current parameters of the target device are displayed on the display interface. Among them, the control device can pre-store the correspondence between the device and the communication protocol, and call the corresponding target communication protocol according to the correspondence. The control device can also identify each device installed on the bicycle according to the vehicle model information or by broadcasting, and call the corresponding target communication protocol according to the identification result.

[0031] Exemplarily, the parameters of the transmission include the gear position of the transmission, the current gear shifting mode (such as manual gear shifting mode or automatic gear shifting mode), whether the gear shift is successful, the number of successful gear shifts, the number of failed gear shifts, the mileage of the bicycle, the number of rotations of the bicycle tires, the bicycle pedal position, the pedal pedaling frequency, the torque applied to the pedals, the gear shifting time, the motor data corresponding to the gear position, the bicycle status before and after the gear shift, the bicycle's tilt angle, the bicycle's tire speed, etc.

[0032] The parameters of the smart lock include the switch status of the smart lock, the conditions for the smart lock to automatically unlock or lock, etc.

[0033] The parameters of the motor include the switching state of the motor, the motor state corresponding to the gear position of the transmission, the motor speed, the motor temperature, the output power of the motor, the output torque of the motor, the average power consumption of the motor, and the voltage and current parameters of the motor.

[0034] The power supply parameters include power on / off status, power level, charging time, power supply temperature, etc.

[0035] The parameter adjustment interface can also display the network connection status of the control device, the connection status or connection method between the control device and each device (such as Internet of Vehicles connection, Bluetooth connection, 5G connection), etc.

[0036] The user can select the parameter to be adjusted on the display interface according to the current parameter and input the corresponding parameter adjustment instruction. The control device can also respond to the user's instruction to select the parameter and display various parameter adjustment instructions on the display interface for the user to select. The control device can also parse the voice information or text information input by the user to obtain the parameter adjustment instruction.

[0037] S103: Determine a target device corresponding to the parameter adjustment instruction, where the target device is any one or more of a transmission, a motor, a smart lock, and a power supply installed on the bicycle.

[0038] Specifically, the control device may determine the target device corresponding to the parameter adjustment instruction according to the parameter adjustment instruction and the correspondence between the preset parameters and each device, or may parse the corresponding target device from the parameter adjustment instruction.

[0039] It is understood that for any parameter adjustment instruction, the control device can adjust the parameters of one device according to the parameter adjustment instruction, or can adjust the parameters of multiple devices at the same time. For example, if the parameter adjustment instruction is a shift instruction, the control device adjusts the parameters of the motor and the transmission at the same time according to the parameter adjustment instruction.

[0040] S104: calling the target communication protocol corresponding to the target device to send the parameter adjustment instruction to the target device.

[0041] Specifically, the control device may determine the target communication protocol according to the mapping relationship between the device and the communication protocol, call the target communication protocol to establish a communication connection with the target device, and thereby send a parameter adjustment instruction to the target device.

[0042] In the above embodiment, by pre-storing the communication protocols corresponding to each device, obtaining the parameter adjustment instructions input in the parameter adjustment interface, calling the corresponding target communication protocol to send the parameter adjustment instructions to the target device, the user can uniformly adjust the parameters of other devices through one device, thereby simplifying the parameter adjustment process, improving the adjustment efficiency, and thus improving the user's riding experience. At the same time, during the bicycle assembly process, different devices can be connected to the same control device (such as a handheld panel), which can improve the flexibility of the bicycle assembly process and improve the assembly efficiency.

[0043] In one embodiment, the control device also obtains a riding scene, and the riding scene includes any one or more of the current terrain, riding speed, and output torque of the motor. Among them, the current terrain is any one of uphill, downhill, mountainous, flat, etc., which can be determined according to the acceleration detected by the acceleration sensor, the riding speed is determined according to the acceleration information or the wheel speed, and the output torque of the motor is obtained from the motor. Afterwards, the control device inputs the riding scene into the prediction model to obtain the prediction parameters of the target device output by the prediction model. Among them, the prediction model is trained based on historical riding scenes and historical parameters corresponding to the target device. Exemplarily, multiple groups of riding scenes and parameters of each device set by the user are collected in advance to obtain training samples, and the training samples are input into the classification model to optimize the parameters of the classification model to obtain the prediction model. Among them, the training samples can be obtained based on the riding data of the user of the bicycle, or based on the riding data of multiple users. The control device can store the prediction model in advance, or obtain the prediction model from the server to obtain the prediction parameters of the target device.

[0044] The control device can output the predicted parameters or the language playback predicted parameters on the display interface, and the user can determine whether to adjust the parameters of the target device to the corresponding predicted parameters according to actual needs, so that the user can quickly complete the parameter adjustment. The control device can also adjust each device according to the predicted parameters in the automatic parameter switching mode.

[0045] In one embodiment, the control device can set the current mode to the automatic shift mode or the manual shift mode according to the user's instruction. The manual shift mode instructs the transmission to shift according to the user's shift instruction, and the automatic shift mode instructs the transmission to shift according to the speed of the bicycle. In the automatic shift mode, the control device can control the transmission to shift at an appropriate time according to the bicycle's running speed or pedaling information, thereby improving the riding experience when shifting gears.

[0046] In one embodiment, in the automatic shifting mode, the control device first obtains the running speed of the bicycle, and if it is determined that the running speed reaches the shifting threshold, the transmission is controlled to shift according to the pedal torque and / or pedal position of the bicycle. The control device can obtain the current gear position, and determine the shifting threshold of the current gear position according to the corresponding relationship between the gear position and the shifting threshold. The corresponding relationship between the gear position and the shifting threshold can be a fixed value, or it can be determined according to the riding scene. The control device can also obtain the shifting threshold input by the user.

[0047] In one embodiment, when the control device determines that the driving speed reaches the shifting threshold, if it detects that the pedal torque is less than or equal to the first preset value, it determines that the output torque of the motor is small and instructs the transmission to shift gears, thereby reducing the impact of shifting gears.

[0048] When the control device determines that the driving speed reaches the shifting threshold, if it detects that the pedal torque is greater than the first preset value and less than the second preset value, it further determines the pedal position, and if the pedal position is in the preset vertical interval, it instructs the transmission to shift gears. The pedal position can be determined based on the acceleration collected by the acceleration sensor on the pedal. The pedal being in the preset vertical interval means that one of the two pedals is at the top position and the other is at the bottom position. At this time, the output torque of the motor is smaller than the torque when the pedal is in other positions. At this time, shifting gears can reduce the impact of shifting gears.

[0049] When the control device determines that the driving speed reaches the shifting threshold, if it detects that the pedal torque is greater than or equal to the second preset value, the pedal position is determined, and if the pedal position is within the preset interval threshold, the transmission is instructed to shift gears. The preset interval threshold is the interval where the pedal is located when the motor output torque is small, so that the gear shift can be performed when the motor output torque is small, reducing the impact of the gear shift. The first preset value is less than the second preset value, and the first preset value and the second preset value can be obtained according to experimental data.

[0050] When the control device detects that the pedal torque is greater than or equal to the second preset value and the pedal position is not within the preset interval threshold, for example, the heights of the two pedals are the same and the pedals are in the horizontal interval, the output torque of the motor is large at this time, so no gear shifting is performed and the control device continues to wait for the appropriate gear shifting opportunity, thereby improving the user's riding experience.

[0051] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
