For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatus.

[0048] Figure 1 The present invention provides a flow chart of a first electric bicycle shift control method. This embodiment is applicable to the shifting of electric bicycles. The method can be executed by the electric bicycle shift control device in the embodiment of the present invention. The device can be implemented in software and / or hardware. Figure 1 As shown, the method is executed by a shift control device of an electric bicycle, and the shift control method of the electric bicycle specifically includes:

[0049] S101. Determine whether the electric bicycle is performing a gear shifting operation according to a gear shifting parameter detected by a gear shifting control sensor.

[0050] Specifically, the gear shift control sensor can be set on the rear wheel of the electric bicycle to detect whether the electric bicycle is performing a gear shift operation. The gear shift parameter can be a parameter signal detected by the gear shift control sensor. The controller can determine whether the electric bicycle is performing a gear shift operation based on the gear shift parameter detected by the gear shift control sensor, so as to perform subsequent operations.

[0051] S102: When the electric bicycle is performing a gear shifting operation, the motor is controlled to stop power output, and a rear wheel speed and a pedaling frequency signal of the electric bicycle at the current moment are obtained.

[0052] Specifically, when it is determined that the electric bicycle is performing a gear shifting operation, the motor is controlled to stop power output, so that the friction and wear caused by the operation of the motor can be reduced during the gear shifting process, thereby reducing the mechanical damage to the transmission system in the electric bicycle and extending the life of the transmission system.

[0053] Specifically, the rear wheel speed of the electric bicycle detected by the speed detection sensor at the current moment is obtained; and the pedaling frequency signal of the electric bicycle detected by the pedaling frequency sensor at the current moment is obtained.

[0054] Specifically, a speed detection sensor is provided on the rear wheel of the electric bicycle so as to detect the speed of the rear wheel in real time. The speed sensor is electrically connected to the controller so as to transmit the detected rear wheel speed at the current moment to the controller. The cadence sensor can be provided on the crank or chain ring of the electric bicycle. The cadence sensor can track the rotation of the pedals in real time, and then can detect the cadence information such as the pedaling rhythm of the rider. The cadence sensor is electrically connected to the controller so as to transmit the detected cadence signal at the current moment to the controller.

[0055] S103, determining the current gear position according to the current rear wheel speed and the current pedaling frequency signal.

[0056] Specifically, the controller may determine the gear position at the current moment according to the ratio between the rear wheel speed at the current moment and the pedaling frequency signal at the current moment.

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

[0058] Specifically, in an electric bicycle, a mechanical shift switch is directly connected to a mechanical transmission installed on the rear wheel through a mechanical cable, so that mechanical gear position adjustment can be achieved. The electric bicycle is controlled to perform a gear shift operation according to the current gear position to achieve gear shifting, so that the electric bicycle can achieve smooth gear shifting.

[0059] The gear shift control method of an electric bicycle in an embodiment of the present invention determines whether the electric bicycle is performing a gear shift operation based on the gear shift parameters detected by the gear shift control sensor; when the electric bicycle is performing a gear shift operation, the motor is controlled to stop power output, and the rear wheel speed and the pedaling frequency signal of the electric bicycle at the current moment are obtained; the gear position at the current moment is determined based on the rear wheel speed and the pedaling frequency signal at the current moment, and the gear shift operation is performed, which can prevent mechanical wear of the transmission system of the electric bicycle during the gear shift process, thereby extending the service life of the transmission system. In addition, smooth gear shifting can be achieved.

[0060] Optional, Figure 2 A schematic flow chart of a second electric bicycle shift control method provided by an embodiment of the present invention, Figure 2 Based on the above embodiment, the operation of judging whether the electric bicycle is in the process of performing the gear shift operation according to the gear shift parameters detected by the gear shift control sensor is described in detail. Figure 2 As shown, the shift control method of the electric bicycle includes:

[0061] S201, obtaining the gear position of the electric bicycle at the i-th moment.

[0062] Specifically, the i-th moment may be the moment before the current moment. The gear position at each moment may be displayed on the instrument panel, and the instrument panel and the controller are connected in communication, so that the controller may transmit the gear position determined at the current moment to the instrument panel so that the instrument panel may display and update the gear position in real time, and the controller may also obtain the gear position displayed on the instrument panel.

[0063] Specifically, the controller obtains the gear position of the electric bicycle at the i-th moment so as to subsequently adjust the gear position at the i-th moment according to the gear position at the current moment, that is, to 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, controlling the motor to stop power output, and obtaining a rear wheel speed and a pedaling frequency signal of the electric bicycle at the current moment.

[0066] S204: Determine the current gear position according to the current rear wheel speed and the current pedaling frequency signal.

[0067] S205: When the difference between the gear position at the i-th moment and the gear position at the current moment satisfies a preset gear range, the electric bicycle is controlled to maintain the gear position at the i-th moment.

[0068] Specifically, the preset gear range can be understood as the difference range between the gear at the i-th moment and the gear at the current moment. It can be understood that the preset gear range is smaller. If the difference between the gear at the i-th moment and the gear at the current moment is approximately 0, then the difference between the gear at the i-th moment and the gear at the current moment satisfies the preset gear range. In this way, the gear at the current moment is approximately equal to the gear at the i-th moment. There is no need to shift gears, and the electric bicycle can maintain the gear at the i-th moment and continue to drive.

[0069] S206: When the difference between the gear position at the i-th moment and the gear position at the current moment exceeds the preset gear position range, the electric bicycle is controlled to perform a gear shift operation according to the gear position at the current moment.

[0070] Specifically, if the difference between the gear at the i-th moment and the gear at the current moment is large, it means that the gear at the current moment is significantly different from the gear at the i-th moment. In this case, to perform a gear shifting operation, it is necessary to upshift or downshift the gear at the i-th moment according to the gear at the current moment. The controller controls the electric bicycle to continue traveling with the current gear instead of the gear at the i-th moment, so as to ensure normal riding of the electric bicycle.

[0071] The shift control method of the electric bicycle provided by the embodiment of the present invention can determine 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 the 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 perform the gear holding operation 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 the gear shifting operation according to the gear at the current moment to achieve the gear shifting of the electric bicycle. In this way, the smoothness of the gear shifting can be achieved. In addition, the gear of the electric bicycle can be monitored in real time for timely gear shifting, and the use of electric energy during the gear shifting process can be optimized, unnecessary energy loss can be reduced, and the overall energy efficiency of the vehicle can be improved.

[0072] Optional, Figure 3 A schematic flow chart of a third electric bicycle shift control method provided by an embodiment of the present invention, Figure 3 Based on the above embodiment, controlling the electric bicycle to maintain the gear position at the i-th moment and controlling the electric bicycle to shift gears according to the current gear position are described in detail. Figure 3 As shown, the shift control method of the electric bicycle includes:

[0073] S301, obtaining the gear position of the electric bicycle at the i-th moment;

[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, the motor is controlled to stop power output, and a rear wheel speed and a pedaling frequency signal of the electric bicycle at the current moment are obtained.

[0076] S304: Determine the current gear position according to the current rear wheel speed and the current pedaling frequency signal.

[0077] S305: When the difference between the gear position at the i-th moment and the gear position at the current moment satisfies the preset gear range, obtain a preset number of teeth on the chainring.

[0078] Specifically, the preset number of teeth on the chainring is the number of teeth on the front chainring of the electric bicycle that is preset manually on the application. The chainring is part of the bicycle transmission system, located on the pedal shaft (crank), and connected to the flywheel of the rear wheel through a chain. It is responsible for transmitting the pedaling force of the rider to the rear wheel to achieve power output. In addition, the relationship between the number of teeth on the chainring and the gear position is mainly reflected in the gear ratio, which refers to the ratio of the current number of teeth on the chainring to the number of teeth on the flywheel. This ratio determines the transmission ratio of the bicycle, which in turn affects the performance and efficiency of riding. By setting the number of teeth on the chainring, the gear position of the electric bicycle at the i-th moment can be obtained.

[0079] S306, determining the gear position of the electric bicycle at the i-th moment according to the preset number of teeth on the chainring, and controlling the motor to output a first preset power to perform an operation of maintaining the gear position at the i-th moment.

[0080] Specifically, the first preset power output can be understood as the power output of the motor when the motor maintains the gear position at the i-th moment. That is to say, when the gear position at the current moment is approximately the same as the gear position at the i-th moment, the motor output at the current moment needs to maintain the same power output as at the i-th moment to ensure the normal operation of the electric bicycle at the current moment.

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

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

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

[0084] The shift control method for an electric bicycle provided in an embodiment of the present invention determines the power output of the motor according to the difference between the gear position at the i-th moment and the gear position at the current moment, and performs the shift operation, thereby achieving smooth shifting. In addition, the gear position of the electric bicycle can be monitored in real time when necessary to facilitate timely shifting, and the use of electric energy during the shifting process can be optimized, thereby reducing unnecessary energy loss and improving the overall energy efficiency of the vehicle.

[0085] Optional, Figure 4 A schematic flow chart of a fourth electric bicycle shift control method provided by an embodiment of the present invention, Figure 4 Based on the above embodiment, the operation after the electric bicycle performs the gear shifting operation according to the current gear position is described in detail. Figure 4 As shown, the shift control method of the 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, the motor is controlled to stop power output, and a rear wheel speed and a pedaling frequency signal of the electric bicycle at the current moment are obtained.

[0088] S403, determining the current gear position according to the current rear wheel speed and the current pedaling frequency signal.

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

[0090] S405: Control the instrument panel of the electric bicycle to display the current gear position.

[0091] Specifically, the instrument panel displays the current gear position so that the gear position information displayed on the instrument panel can be updated, which is helpful for the rider to check whether the gear shift is successful and the current gear position of the electric bicycle.

[0092] The shift control method of an electric bicycle provided by the embodiment of the present invention controls the instrument panel of the electric bicycle to display the current gear position, so as to update the gear position on the instrument panel for easy viewing.
