[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0047] It should be noted that the terms "comprising" and "etc." and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0048] Figure 1 This is a flowchart illustrating a first method for shifting gears in an electric bicycle according to an embodiment of the present invention. This embodiment is applicable to the shifting of gears in electric bicycles. The method can be executed by the shifting control device for the electric bicycle in this embodiment, which can be implemented using software and / or hardware, such as... Figure 1 As shown, this method is executed by the gear shift control device of the electric bicycle, and the gear shift control method of the electric bicycle specifically includes:

[0049] S101. Determine whether the electric bicycle is performing a gear shifting operation based on the gear shifting parameters detected by the gear shifting control sensor.

[0050] Specifically, a gear shifting sensor can be installed on the rear wheel of an electric bicycle to detect whether the bicycle is performing a gear shift. The gear shifting parameters can be the signals detected by the sensor. The controller can determine whether the electric bicycle is performing a gear shift based on these parameters and then execute subsequent operations accordingly.

[0051] S102. When the electric bicycle is performing a gear shifting operation, control the motor to stop power output and obtain the rear wheel speed and pedal frequency signals of the electric bicycle at the current moment.

[0052] Specifically, when it is determined that the electric bicycle is performing a gear shift, the motor is controlled to stop power output. This reduces friction and wear caused by motor operation during gear shifting, thereby reducing mechanical damage to the electric bicycle's internal transmission system and extending its lifespan.

[0053] Specifically, the speed sensor detects the rear wheel rotation speed of the electric bicycle at the current moment; the cadence sensor detects the cadence signal of the electric bicycle at the current moment.

[0054] Specifically, a speed sensor is installed on the rear wheel of the electric bicycle to detect the rear wheel speed in real time. The speed sensor is electrically connected to the controller to transmit the detected current rear wheel rotation speed to the controller. A cadence sensor can be installed on the crank or chainring of the electric bicycle. The cadence sensor tracks the rotation of the pedals in real time, thereby detecting cadence information such as the rider's pedaling rhythm. The cadence sensor is also electrically connected to the controller to transmit the detected current cadence signal to the controller.

[0055] S103. Determine the gear at the current moment based on the current rear wheel speed and the current cadence signal.

[0056] Specifically, the controller can determine the gear at the current moment based on the ratio between the current rear wheel speed and the current pedal frequency signal.

[0057] S104. Control the electric bicycle to perform a gear shifting operation according to the current gear position.

[0058] Specifically, in electric bicycles, the mechanical gear shift switch is directly connected to the mechanical derailleur mounted on the rear wheel via a mechanical cable, enabling mechanical gear shifting. The electric bicycle is controlled to perform gear shifting operations based on the current gear position, thus achieving smooth gear changes.

[0059] The gear shifting control method for electric bicycles in this invention determines whether the electric bicycle is performing a gear shifting operation based on the gear shifting parameters detected by the gear shifting control sensor. When the electric bicycle is performing a gear shifting operation, the motor is controlled to stop power output, and the rear wheel speed and pedal frequency signal of the electric bicycle at the current moment are acquired. The gear at the current moment is determined based on the rear wheel speed and pedal frequency signal, and the gear shifting operation is performed. This can prevent mechanical wear of the electric bicycle's transmission system during gear shifting, thereby extending the service life of the transmission system. In addition, it can achieve smooth gear shifting.

[0060] Optional, Figure 2 This is a schematic flowchart of a second gear shifting control method for an electric bicycle provided in an embodiment of the present invention. Figure 2 Based on the above embodiments, the operation of determining whether an electric bicycle is performing a gear shift operation based on the shift parameters detected by the shift control sensor is described in detail, such as... Figure 2 As shown, the gear shifting control method of this electric bicycle includes:

[0061] S201, Obtain the gear position of the electric bicycle at time i.

[0062] Specifically, the i-th moment can be the previous moment. The gear position at each moment can be displayed on the instrument panel. The instrument panel and the controller are connected by communication, so the controller can transmit the determined gear position at the current moment to the instrument panel for real-time display and updating. At the same time, the controller can also obtain the gear position displayed on the instrument panel.

[0063] Specifically, the controller obtains the gear position of the electric bicycle at time i, so that it can adjust the gear position at time i based on the current gear position, i.e., perform a gear shifting operation.

[0064] S202. Determine whether the electric bicycle is performing a gear shifting operation based on the gear shifting parameters detected by the gear shifting control sensor.

[0065] S203. When the electric bicycle is performing a gear shifting operation, control the motor to stop power output and obtain the rear wheel speed and pedal frequency signals of the electric bicycle at the current moment.

[0066] S204. Determine the gear at the current moment based on the current rear wheel speed and the current cadence signal.

[0067] S205. When the difference between the gear at time i and the gear at the current time meets the preset gear range, the electric bicycle is controlled to maintain the gear at time i.

[0068] Specifically, the preset gear range can be understood as the range of differences between the gear at time i and the gear at the current time. It can be understood that the preset gear range is small. If the difference between the gear at time i and the gear at the current time is approximately 0, then the difference between the gear at time i and the gear at the current time satisfies the preset gear range. In this case, the gear at the current time is approximately equal to the gear at time i, and there is no need to shift gears. The electric bicycle can continue to travel in the gear at time i.

[0069] S206. When the difference between the gear at time i and the gear at the current time exceeds the preset gear range, the electric bicycle is controlled to perform a gear shifting operation according to the gear at the current time.

[0070] Specifically, if the difference between the gear at time i and the gear at the current time is large, it means that the gear at the current time is significantly different from the gear at time i. In this case, to perform a gear shift, the gear at time i needs to be shifted up or down based on the gear at the current time. The controller then controls the electric bicycle to continue driving at the current gear instead of the gear at time i, in order to ensure the normal riding of the electric bicycle.

[0071] The gear shifting control method for electric bicycles provided in this invention determines whether the gear at the current moment is approximately equal to the gear at the i-th moment by comparing the difference between the gear at the i-th moment and the gear at the current moment with a preset gear range. When the gear at the current moment is approximately equal to the gear at the i-th moment, the electric bicycle is controlled to maintain the gear at the i-th moment. When the difference between the gear at the current moment and the gear at the i-th moment is large, the electric bicycle is controlled to perform a gear shifting operation according to the gear at the current moment, thereby achieving gear shifting smoothness. In addition, the gear position of the electric bicycle can be monitored in real time for timely gear shifting, optimizing energy use during gear shifting, reducing unnecessary energy loss, and improving the overall energy efficiency of the vehicle.

[0072] Optional, Figure 3 This is a flowchart illustrating the third type of gear shifting control method for an electric bicycle provided in an embodiment of the present invention. Figure 3 Based on the above embodiments, the methods for controlling the electric bicycle to maintain the gear at time i and controlling the electric bicycle to perform a gear shifting operation according to the current gear are described in detail, such as... Figure 3 As shown, the gear shifting control method of this electric bicycle includes:

[0073] S301, Obtain the gear position of the electric bicycle at time i;

[0074] S302. Determine whether the electric bicycle is performing a gear shifting operation based on the gear shifting parameters detected by the gear shifting control sensor.

[0075] S303. When the electric bicycle is performing a gear shifting operation, control the motor to stop power output and obtain the rear wheel speed and pedal frequency signals of the electric bicycle at the current moment.

[0076] S304. Determine the gear at the current moment based on the current rear wheel speed and the current cadence signal.

[0077] S305. When the difference between the gear position at time i and the gear position at the current time meets the preset gear position range, obtain the preset number of teeth on the chainring.

[0078] Specifically, the preset chainring tooth count is the number of teeth on the front chainring of an electric bicycle that is manually set in the application. The chainring is part of the bicycle's drivetrain, located on the pedal axle (crank), and connected to the rear sprocket via the chain. It is responsible for transmitting the rider's pedaling power to the rear wheel, thus generating power. Furthermore, the relationship between the chainring tooth count and the gear position is mainly reflected in the gear ratio, which is the ratio of the current chainring tooth count to the sprocket tooth count. This ratio determines the bicycle's gear ratio, thus affecting riding performance and efficiency. By setting the chainring tooth count, the gear position of the electric bicycle at time i can be determined.

[0079] S306. Determine the gear position of the electric bicycle at time i based on the preset number of teeth on the chainring, and control the motor to output the first preset power to maintain the gear position at time i.

[0080] Specifically, the first preset power output can be understood as the power output of the motor when it maintains the gear at time i. In other words, when the gear at the current time is approximately the same as the gear at time i, the motor output at the current time needs to maintain the same power output as at time i in order to ensure the normal operation of the electric bicycle at the current time.

[0081] S307. When the difference between the gear at time i and the gear at the current time exceeds the preset gear range, the motor is controlled to output power with the second preset power according to the gear at the current time to perform a gear shifting operation.

[0082] Specifically, the second preset power output can be understood as the power output of the motor when it is in the current gear. In other words, when the gear at the current moment is significantly different from the gear at the i-th moment, the motor output at the current moment will be different from the power output at the i-th moment, so as to ensure the normal operation of the electric bicycle at the current moment.

[0083] Specifically, when the gear at the current moment is greater than the gear at the i-th moment, the second preset power output is greater than the first preset power output; when the gear at the current moment is less than the gear at the i-th moment, the second preset power output is less than the first preset power output.

[0084] The gear shifting control method for electric bicycles provided in this invention determines the motor's power output based on the difference between the gear position at time i and the gear position at the current time, and performs a gear shifting operation. This enables smooth gear shifting. Furthermore, it allows for real-time monitoring of the electric bicycle's gear positions for timely gear shifting, optimizes energy usage during gear shifting, reduces unnecessary energy loss, and improves the overall energy efficiency of the vehicle.

[0085] Optional, Figure 4 This is a flowchart illustrating the fourth gear shifting control method for an electric bicycle provided in an embodiment of the present invention. Figure 4 Based on the above embodiments, the operation after the electric bicycle performs a gear shift operation according to the current gear position is described in detail, such as... Figure 4 As shown, the gear shifting control method of this electric bicycle includes:

[0086] S401. Determine whether the electric bicycle is performing a gear shifting operation based on the gear shifting parameters detected by the gear shifting control sensor.

[0087] S402. When the electric bicycle is performing a gear shifting operation, control the motor to stop power output and obtain the rear wheel speed and pedal frequency signals of the electric bicycle at the current moment.

[0088] S403. Determine the gear at the current moment based on the current rear wheel speed and the current cadence signal.

[0089] S404. Control the electric bicycle to perform gear shifting operation according to the current gear position.

[0090] S405. The dashboard of the electric bicycle displays the current gear.

[0091] Specifically, the dashboard displays the current gear position so that the displayed gear information can be updated, which helps riders check whether the gear shift was successful and the current gear position of the electric bicycle.

[0092] The gear shifting control method for electric bicycles provided in this embodiment of the invention controls the display of the current gear position on the instrument panel of the electric bicycle, so as to update the gear position on the instrument panel for easy viewing.

[0093] This invention also provides a gear shifting control device for an electric bicycle. Figure 5 This is a schematic diagram of the structure of a gear shifting control device for an electric bicycle provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the gear shifting control device of the electric bicycle includes:

[0102] The gear holding operation unit is used to control the electric bicycle to hold the gear at the i-th moment when the difference between the gear at the i-th moment and the gear at the current moment meets the preset gear range.

[0103] The gear shifting execution unit is used to control the electric bicycle to perform a gear shifting operation according to the current gear when the difference between the gear at time i and the gear at the current time exceeds the preset gear range.

[0104] Optionally, the gear position holding operation unit at time i includes a preset chainring tooth count acquisition subunit and a gear position holding operation subunit at time i. The gear shift execution operation unit includes a gear shift execution operation subunit.

[0105] The preset number of teeth acquisition subunit is used to acquire the preset number of teeth on the crankcase.

[0106] The gear position operation subunit for holding the gear at time i is used to determine the gear of the electric bicycle at time i based on the preset number of teeth on the chainring, and control the motor to output the first preset power to hold the gear at time i.

[0107] The gear shifting operation subunit is used to control the motor to output power with a second preset power according to the current gear position and perform the gear shifting operation.

[0108] Optionally, the parameter acquisition module includes a rear wheel speed acquisition submodule and a cadence signal acquisition submodule.

[0109] The rear wheel speed acquisition submodule is used to acquire the rear wheel speed of the electric bicycle at the current moment, as detected by the speed detection sensor.

[0110] The cadence signal acquisition submodule is used to acquire the cadence signal of the electric bicycle at the current moment detected by the cadence sensor.

[0111] Optionally, the shift control device for electric bicycles may also include a dashboard display control module.

[0112] The dashboard display control module is used to control the display of the current gear on the dashboard of the electric bicycle.

[0113] The electric bicycle shift control device provided in this embodiment of the invention uses a shift operation judgment module to determine whether the electric bicycle is performing a shift operation based on shift parameters detected by a shift control sensor; a parameter acquisition module to control the motor to stop power output when the electric bicycle is performing a shift operation, and to acquire the rear wheel speed and pedal frequency signal of the electric bicycle at the current moment; a current gear determination module to determine the current gear based on the current rear wheel speed and pedal frequency signal; and a shift execution operation module to control the electric bicycle to perform a shift operation based on the current gear.
